PREPARATION
Never operate the tractor and mower until you have read and completely understand this manual, the Tractor Operator’s Manual, and each of the Safety Messages found on the safety signs on the tractor and mower. Personal protection equipment including hard hat, safety glasses, safety shoes, and gloves are recommended during assembly, installation, operation, adjustment, maintaining, repairing, removal, or moving the implement. Do not wear loose clothing, gloves, neckties, rings, bracelets, or other jewelry which may get caught in moving parts. Wear protective hair covering to contain long hair. PROLONGED EXPOSURE TO LOUD NOISE MAY CAUSE PERMANENT HEARING LOSS! Tractors with or without Mowers attached can often be noisy enough to cause permanent, partial hearing loss. We recommend that you wear hearing protection on a full- time basis if the noise in the Operator’s position exceeds 80db. Noise over 85db on a long-term basis can cause severe hearing loss. Noise over 90db adjacent to the Operator over a long-term basis may cause permanent, total
3

hearing loss. NOTE: Hearing loss from loud noise (from tractors, chain saws, radios, and other such sources close to the ear) is cumulative over a lifetime without hope of natural recovery. Operate the mower only with a tractor equipped with an approved Roll-Over Protective System (ROPS). Always wear your seat belt on tractors equipped with a ROPS. Serious injury or even death could result from falling off the tractor – particularly during a turnover when the operator could be pinned under the ROPS or the tractor. Clear area to be cut of stones, branches or other debris that might be thrown, causing injury or damage. Operate only in daylight or good artificial light. Ensure mower is properly mounted, adjusted and in good operating condition. Make sure driveline spring-activated locking pin operates freely and is seated firmly in tractor PTO stub shaft groove. Ensure that all safety shielding and safety signs are properly installed and in good condition.

MAINTENANCE SAFETY
Make sure there is plenty of ventilation. Never operate the engine of the towing vehicle in a closed building. The exhaust fumes may cause asphyxiation. Before working on this machine, drive to a level area, disengage the PTO, lower implement (or if working underneath, raise and block securely), shut off the engine, set the brakes, and remove the ignition keys. Be certain all moving parts on attachments have come to a complete stop before attempting to perform maintenance. Never work under equipment unless it is blocked securely. Never depend on hydraulic system to keep implement in raised position. Keep all persons away from operator control area while performing adjustments, service, or maintenance. Always use personal protection devices such as eye, hand and hearing protectors, when performing any service or maintenance. Frequently check mower blades. They should be sharp, free of nicks and cracks and securely fastened. Periodically tighten all bolts, nuts and screws and check that all cotter pins are properly installed to ensure unit is in a safe condition. When completing a maintenance or service function, make sure all safety shields and devices are installed before placing unit in service. After servicing, be sure all tools, parts and service equipment are removed. Check to ensure all safety signs are installed and in good condition. (See safety sign section for location drawing.) Do not allow grease or oil to build up on any deck or platform.
5

Where replacement parts are necessary for periodic maintenance and servicing, genuine factory replacement parts must be used to restore your equipment to original specifications. The manufacturer will not claim responsibility for use of unapproved parts and/or accessories and other damages as a result of their use. If equipment has been altered in any way from original design, the manufacturer does not accept any liability for injury or warranty. A fire extinguisher and first aid kit should be kept readily accessible while performing maintenance on this equipment.
TRANSPORT SAFETY
Comply with state and local laws govering highway safety and movement of farm machinery on public roads. The use of flashing amber lights is acceptable in most localities. However, some localities prohibit their use. Local laws should be checked for all highway lighting and marking requirements. When driving the tractor and equipment on the road or highway under 20 mph at night or during the day, use flashing amber warning lights and a slow moving vehicle (SMV) identification emblem. Always be sure the implement is in the proper raised position for transport. Reduce speed when transporting mounted implements to avoid bouncing and momentary loss of steering control. Plan your route to avoid heavy traffic. Do not drink and drive! Watch for traffic when operating near or crossing roadways. Use extreme care and maintain minimum ground speed when transporting on hillside, over rough ground and when operating close to ditches or fences. Be careful when turning sharp corners. Turn curves or go up or down hills only at a low speed and at a gradual steering angle. Make certain that at least 20% of the tractor’s weight is on the front wheels to maintain safe steerage. Slow down on rough or uneven surfaces, and loose gravel. Never allow riders on either tractor or mower. Be a safe and courteous driver. Always yield to oncoming traffic in all situations like narrow bridges and intersections.

OPERATION INSTRUCTION
The safe operation of this mower is the responsibility of the operator. The operator should be familiar with the machine, tractor and all safety practices before starting operation. This mower is designed for lawn and grass mowing. It is not designed for rough conditions or heavy mowing. The mower is equipped with suction type blades, which are best suited for lawn mowing. Always operate tractor PTO at 540RPM. This chapter provides information for attaching mower to tractor and preparing it for field operation. Review this data prior to tractor hookup and operation.
TRACTOR PREPARATION Do not install mower on a tractor over 40 HP.
WARNING!
Do not operate tractor with less than 20% of its gross unballasted mass on the front wheels with the mower in the transport position. WHEEL TREADS Tractor wheel tread spacing should be increased when working on inclines or rough ground to reduce the possibility of tipping. STABILIZER BARS AND SWAY BLOCKS Use stabilizer bars or sway blocks to prevent side sway of the mower. DRAWBAR Shorten or remove the tractor drawbar so it will not interfere with the up and down movement of the mower.
WARNING!
Do not get between tractor and mower when the engine is running. ATTACHING THE MOWER TO TRACTOR (LIFT TYPE ONLY) This mower is designed for tractors with 540 RPM and category I hitch. Back the tractor up to the mower so that the lower draft arms are in alignment with the mower lift pins. Stop the engine, lock the brakes or place the tractor in park. Connect the tractor and stabilizer bars to the lower lift pins. Adjust the top link so it will pin to the top holes in the A-Frame or into the holes in the floating top link.
DANGER!
Never allow children to operate, ride or come close to the mower or tractor. Usually, 15-16 year old children who are mature and responsible can operate the mower with reasonable safety if they have read the operator’s manual, been trained in safe operation of the machine, and are physically large and strong enough to reach and operate the controls easily. DRIVELINE ATTACHMENT TO TRACTOR
10

1. Slide yoke onto the tractor PTO shaft. 2. Move yoke back and forth until locking pin has engaged on the PTO shaft groove.
WARNING!
When attaching the driveline yoke to the tractor PTO shaft, it is important that the spring activated locking pin seats properly in the tractor PTO shaft groove.
CUTTING HEIGHT ADJUSTMENT
WARNING!
Avoid personal injury! Be sure tractor engine is off, that key is removed from ignition and allow blades to completely stop turning before dismounting to make adjustments. Important: Avoid very low cutting heights. Striking the ground with the blades gives the most damaging shock loads a mower can encounter and will cause damage to it and the driveline. 1. Using the tractor, raise the mower off the ground and place supports underneath of it, so that it will not drift downwards while making adjustments or maintenance. 2. While supporting the wheel and yoke assembly off the ground, remove the snapper pin from the top of the gauge wheel spindle. Position the supplied spacers as required for achieving the desired cutting height.
TRACTOR REQUIREMENTS AND PREPARATION
This Finishing Mower is designed for light duty cutting such as lawn maintenance with a Category I, 3 pt. hitch and with a 540 rpm PTO. This mower is not designed for tractors over 40 horsepower. The PTO must be in good working condition. It is recommended that only tractors with wide front axles be used with this cutter. Tricycle front wheel arrangements are inherently unstable and tractor rollover accidents are more likely to occur. Tractor wheel tread spacing should be increased when working on inclines or rough ground to reduce the possibility of tipping. The tractor also needs lift arm stabilizer bars or sway blocks to control side movement of the cutter. Check the tractor’s 3 pt. hydraulic lift system. Refer to your tractor operator’s manual or dealer for any adjustments necessary to put the hydraulic system in good working order. Be sure tires and rims are in good condition. Inflate tires to the proper recommended air pressure. Check the tractor master shield over the PTO shaft. Make sure it is in good condition and fastened securely to the tractor. Purchase a new shield if old shield is damaged or missing. It is recommended that a ROPS (Roll-Over Protection System) and a seat belt be installed on all tractors. Contact your local dealer for a ROPS for your tractor.
CAUTION!
Be sure your tractor is in good condition. Read all the safety precautions and make sure all tractor operators are familiar with the safety rules of operation.
11

The operator is responsible for the safe operation of this mower. The operator must be properly trained. Operators should be familiar with the mower and tractor and all safety practices before starting operation. Read the safety rules and safety signs before operation. Recommended mowing speed for most conditions is from two to five mph.
WARNING!
When using the unit, a minimum 20% of tractor and equipment weight must be on tractor front wheels. Without this weight, tractor could tip up, causing possible loss of control and possible personal injury or death. The weight may be attained with a front end loader, front wheel weights, ballast in tires or front tractor weights. When attaining a minimum 20% of tractor and equipment weight on the front wheels, you must not exceed the ROPS weight certification. Weigh the tractor and equipment. DO NOT GUESS OR ESTIMATE!
WARNING!
A heavy load can cause instability in driving a tractor. Make sure the front of the tractor is properly counterbalanced with weights. Always drive slowly – especially around turns. An unstable tractor could steer badly and possibly tip over, causing injury or death.
DANGER!
For non-agricultural applications, OSHA, ASAE SAE and ANSI standards require the use of chain guards, deflectors or solid skirts at all times. The mower manufacturer strongly recommends the use of chain guards, rubber belting or solid skirts for agricultural applications as well, to reduce the risk of property damage, serious bodily injury or even death from objects thrown or from contact with the cutting blades. Front, rear, left and right are determined by the normal direction of travel, the same as when driving an automobile.
STARTING AND STOPPING MOWER
The power required for operating the mower is supplied via the tractor PTO. Refer to your tractor’s manual for instructions on engaging and disengaging the PTO. 1. Always engage the PTO at low engine RPM. 2. Operate the mower at 540 RPM PTO speed. Do not exceed 540 RPM PTO speed. 3. In case of emergency, you must learn how stop the tractor and mower quickly. Important: Stop cutter and tractor immediately upon striking an obstruction. Inspect the mower and
12

repair any damage before resuming operation. Do not disengage PTO when the engine is at full PTO RPM. Always bring the tractor engine to idle speed before disengaging the PTO. !
WARNING!
Avoid personal injury! When attempting to stop a tractor which does not have a live PTO, the momentum created by the blades of a mower can cause the tractor to be pushed forward. Do not operate this mower unless the tractor has a live or independent PTO. To start operation, reduce engine speed and engage the tractor PTO. Before starting to cut, gradually increase the engine speed to develop full PTO speed. Enter the area to be cut with the cutter operating at PTO speed and, if it becomes necessary to temporarily regu-late engine speed during operation, increase or decrease the speed gradually. To transport the mower, disengage the PTO and raise to full transport height.
CUTTING SPEED
Proper ground speed for cutting will depend upon the height, type, and density of the grass to be cut. Normally, ground speed will range from 1.5 to 3 MPH. Tall dense grass should be cut at low speeds, while thin medium height grass can be cut at faster ground speeds.
CUTTING TIPS
Always operate the PTO at the recommended RPM when cutting. This is necessary for correct blade speed, which creates a clean and even grass cut. Under certain conditions the tractor tires may roll some grass blades down and prevent them from being cut at the same height as the surrounding area. If this occurs, reduce the tractor ground speed, but maintain 540 RPM PTO speed. The lower ground speed will allow grasses to be at least partially rebound and cut. Taking a partial cut and/or reversing the direction of travel may also produce a cleaner cut. When people are passing by the area you are cutting, stop the cutting until the area has been cleared. Although the mower is shielded to prevent objects from being thrown by the blades, no shielding device is 100% effective. The mower operator has greater knowledge of the hazards created by the machine than people on the street. Therefore, he must take every precaution possible when other people are around.
WARNING!
Avoid personal injury! Pick up all rocks and other debris before cutting. Enter new cutting areas carefully. Cut material higher the first time to allow the mower to clear unseen or hidden objects. Never assume that a cutting area is clear. Always check carefully.
Extremely tall grass should be cut in two stages. First, raise the mower above the desired cutting height and cut the grass in one direction. Second, adjust the mower to the desired cutting height and cut in a perpendicular (90 degree) direction from the first cut.
Before cutting analyze the area to determine the best cutting procedure. One must consider the grass height, its type and the terrain relief.
Grass is best cut when it is dry. Mowing wet grass can cause plugging, which results in grass clumps behind the mower.
DETACHING AND STORING
13

Lower the mower to the ground. Park the tractor with transmission in the correct gear (Automatic transmissions should be set on Park; Standard transmissions should be set on Neutral). Set the parking brake, turn off the engine and remove the keys from the ignition. Wait until the PTO stops rotating completely before dismounting the tractor. Disconnect the driveline from the tractor PTO and store it to prevent contact from the ground and away from excessive moisture. Always reinstall or lower into position the tractor PTO master shield. This shield should always remain in place except when connecting or disconnecting the driveline.
BEFORE OPERATING OR TRANSPORTING THE MOWER
Always display the SMV (slow moving vehicle) symbol on the rear of the tractor that transports the mower. The SMV symbol should be clearly visible to vehicles overtaking the tractor transporting the mower. Prominent display of this symbol will help the operator avoid accidents which could cause injury or possibly death. See figure as below.
MAINTENANCE INSTRUCTIONS
Before operating the mower, make sure that it is properly lubricated and thoroughly inspected. Only a minumum of time and effort is required to regularly lubricate and maintain it. Following a regular program will provide long life and trouble free operation.
WARNING! Always disengage the tractor PTO before raising the mower for transport or making adjustments. LUBRICATION
Do not let excess grease collect on or around parts, particularly when operating in sandy areas. The illustration below show the location of all the lubrication fittings. Use an multi-purpose grease for all the locations. Be sure to clean the grease fitting before applying any grease.Daily lubrication of the driveline U-joints is necessary. Failure to maintain proper lubrication will result in premature ware and damage to the U-joints, gearbox and/or driveline.

Description Gauge Wheel Pivots Blade Spindle

Frequency Every 8hours or daily Every 8hours or daily

Lubrication intervals shown are for mowers operating under normal conditions. Severe or unusual conditions may require more frequent lubrication.

GEARBOX LUBRICATION
The gearbox must be filled with SAE 90 EP oil before operating. To fill gearbox to the correct operating level: 1. Place the mower on an even and leveled surface. 2. Remove filler and test level plug (See figure below for location of plugs). 3. Add oil through the filler plug until it starts running out of the test plug. (Pour oil slowly to make
sure that the lower portion of the gearbox housing has been filled).
4. Screw the test and filler plugs back in their corresponding places.
It is recommended that the oil level plug be removed after every 8-10 hours of operation and oil added until it runs out of the test plug hole. The filler plug hole and test plug hole are both located on the back of side of the gearbox.

Note:
1. It is recommended that the test plug be removed after every 8-10 hours of operation, and oil added to the proper fill level if required.
2. Do not overfill thegearbox with oil. This will result in pressure build up inside the unit, which can cause the oil seals to leak.
3. If the gearbox suddenly starts making and unusual noise, stop at once, check for oil leaks and refill it as required.
GAUGE WHEEL ASSEMBLEIES
The gauge wheels are equipped with bearings which require grease regularly. Grease fittings are provided in the gauge wheel pivot. It is recommended that these be lubricated after every 8 hours of operation.

15

DRIVELINE LUBRICATION
Grease fittings are located on the cross and bearing kit assemblies of both U-joints. U-joints should be greased after every 8 hours of operation. See figure below for the location of the grease fittings. Do not force grease through the needle bearing cup assemblies.
The metal telescoping drive tubes inside the plastic shield tubes must be lubricated before each use. See figure below. Disconnect the driveline from the tractor and pull halves apart (do not disconnect the driveline that is attached to the mower gearbox). Insert grease into drive tube and spread it evenly. Reconnect the two driveline halves together. Reconnect the driveline to the tractor PTO, raise and lower the mower several times so that the grease just applied spreads over the entire working area of the drive tubes.
WARNING!
When attaching the driveline yoke to the tractor PTO shaft, it is important that the spring activated locking pin is seated on the PTO shaft groove. A loose yoke could slip off and result in personal injury or damage to the mower.
BLADE SPINDLE LUBRICATION
Blade spindles must be lubricated after every 8 hours of operation. Each spindle is supplied with a grease fitting,which are positioned together on top of deck,and there are tubes leading the oil into the bearing hub,and it must be lubricated sufficiently.Do not force large amounts of grease on the spindles,as it may get on the drive belts.
BLADE SERVICING
Use only correct specified blades on your mower. They are manufactured of special heat-treated alloy steel. Substitute blades may not meet specifications and may fail in a hazardous manner, which could cause injury.
16

BLADE REMOVAL AND INSTALLATION
Place the machine at a comfortable height and lock it in position with sufficient support to guarantee the operator’s safety. Prevent the blade rotating by locking the shaft with a wrench (the shaft is designed for this with two flat areas immediately above the blade). Unscrew the nut (ref. #1, figure above) and remove the blade. Check the state of wear of the shaft and the nut and, if necessary, replace them. To install the blade, place the blade and washer on the spindle shaft and screw the nut on fully and tighten securely, keeping the shaft locked at the same time as described above.
When installing the blades, the electric impact wrench has a torque value of 167 ft/lbs to 177 ft/lbs for tightening.
Note: Always wear heavy leather gloves while tightening blade bolts.
BLADE SHARPENING
To maintain a proper blade balance, always sharpen both ends of the blade equally. Follow the sharpening pattern as shown in figure below. Do not sharpen the blades to a razor edge, but leave a 1/32″ blunt edge. Never sharpen the back side of the blades.
WARNING!
Avoid personal injury! Always support or block the mower when servicing the blades, carrier or any other component on the underside of the deck.
Hold the end of the blade using heavy leather gloves.

STORAGE
Your mower represents an investment from which you should get the greatest possible benefit and use. Therefore, when the cutting season is over, the mower should be thoroughly checked and prepared for storage so that a minimum amount of work will be required to put it back into operation for the next season. We suggest the following storage procedures: 1. Thoroughly clean the mower. 2. Lubricate the mower as recommended in the maintenance section of this manual. 3. Tighten all bolts and pins to the recommended torque. 4. Check the mower for worn or damaged parts and replace them. 5. Store the mower in a clean, dry place with the deck resting on blocks. 6. Use spray touch up enamel where necessary to prevent rust and maintain its appearance
