SAFETY INFORMATION

2.1 GENERAL
Safety of the operator and bystanders is one of the main concerns in designing and developing a new piece of equipment. Designers and manufacturers build in as many safety features as possible. However, every year many accidents occur which could have been avoided by a few seconds of thought and a more careful approach to handling the equipment.
Most work-related accidents are caused by failure to observe basic safety rules or precautions. An accident can often be avoided by recognizing potentially hazardous situations before an accident occurs. As you assemble, operate, or maintain the rotary cutter (unit), you must be alert to potential hazards. You should also have the necessary training, skills, and tools to perform any assembly or maintenance procedures.
Improper operation and maintenance of this unit could result in a dangerous situation that could cause injury or death.

1. Start the tractor and cycle the wing lift control lever several times to purge any trapped air and charge the hydraulic cylinders.

NOTICE
The cutter does not have a hydraulic reservoir and therefore can deplete the oil in the tractor’s reservoir during initial charging of the cylinders. Check the tractor’s hydraulic oil reservoir after this initial setup and add oil as necessary.

2. Remove the wing uplock pins. ( 4 Places )

3. To prevent loss, lay the lock-bracket back until hitting the stop, then install the pins in the hole for safe storage.

5.4 CHECKING THE DRIVELINE LENGTH

Before operating the rotary cutter, make sure the driveline will not bottom out or become disengaged. Bottoming out occurs when the inner shaft penetrates the outer housing until the assembly can shorten no more. Bottoming out can cause serious damage to the tractor PTO by pushing the PTO into the tractor and through the support bearings or downward onto the PdiTffeOresnht raaftet,s.breaking it off. A broken driveline can cause personal injury.

5.5 SHORTENING THE DRIVELINE

1. Move the rotary cutter up and down to get the shortest possible distance between the tractor PTO shaft and the gearbox input shaft. Shut down the tractor PTO shaft and the gearbox input shaft. Shut down the tractor leaving the rotary cutter in the position of shortest distance. Securely block the rotary cutter in position.
2. Separate the driveline into two halves and connect them to the tractor PTO and gearbox.
3. Place the driveline halves parallel to one another to determine how much to shorten the driveline.
4. Each section should end approximately 3″ short of reaching the universal joint shield on the opposite section. If too long, measure

3″ back from the universal joint shield and mark on the opposite section.
5. Repeat Step 4 for the other half of the drive.
6. Raise and lower the rotary cutter to determine the position with the greatest distance between the PTO shaft and the gearbox input shaft. Shut down the tractor leaving the rotary cutter in the position of greatest distance. Securely block the rotary cutter in position.
7. Hold the driveline sections parallel to each other and check for minimum 6″ overlap. If the driveline has been marked for cutting, the overlap will be the distance between the two marks. If the driveline has less than the minimum overlap, do not use. Contact your IronCraft dealer.

NOTICE
If the driveline is the correct length, omit the following Steps 8 – 9 and proceed to Step 10.

8. Clamp a driveline section in a well-padded vice to prevent damage to the shield. Cut off the shield where marked. Using the cut off section of the shield as a guide, cut the shaft the same amount. Repeat for the other driveline section.
9. File and clean the cut ends of both drive halves. Remove all chips and filings.
10. Apply multi-purpose grease around the inner driveline section. Slide the drive

halves over each other several times to distribute the grease. Install the driveline on tractor and rotary cutter. Make certain the driveline shielding is in place and in good condition.
11. Set the tractor lift control stop to a position that will prevent the driveline from contacting the front edge of the rotary cutter deck when the rotary cutter is fully raised.

NOTICE
Do not use the rotary cutter if proper driveline engagement cannot be obtained through these methods. Contact your IronCraft dealer.

6.4 SETTING THE ROTARY CUTTER

Properly setting the rotary cutter is essential for efficient and safe operation. A properly set rotary cutter will make a more uniform cut, distribute clippings more evenly, require minimal tractor work, and

follow the contour of uneven terrain. The two adjustments to make before cutting are:
· Leveling front-to-back · Cutting height

NOTICE
Avoid very low cutting heights. Striking the ground with the blades causes damaging shock loads and will cause damage to the rotary cutter and drive. Blades contacting the ground may cause objects to be thrown out from under the cutter deck. Avoid operating the rotary cutter at a height which causes the blades to contact the ground.

6.4.1 LEVELING FRONT-TO-BACK
1. Locate the tractor and cutter on a flat, level surface and use the hydraulics to adjust the cutter height until the front skid shoes are two to three inches off the ground.
2. Shorten or lengthen the leveling rods, as needed, until the front of the deck is level with the rear of the deck. Lengthening the leveling rods raises the back of the cutter.
a. Operating the rotary cutter with the deck approximately 3/4″ higher in the rear than the front will allow the rotary cutter to cut

the grass only once and requires less work from the tractor.
b. Operating the rotary cutter with the deck approximately 3/4″ higher in the front than the rear will increase mulching of the grass or crop material.
c. Operating the rotary cutter at any position other than level with the ground will result in a slightly uneven cut.
3. Adjust the leveling rods to have equal amounts of tension.

6.4.2 SETTING THE CUTTING HEIGHT

The rotary cutter should be operated at the highest position, which will give the desired cutting results. This will help prevent the blades from striking the ground, increasing blade life, and reducing stress on the rotary cutter and tractor.
1. Park the tractor and rotary cutter on level ground.

2. Using the tractor hydraulic cylinder control lever, position the front of the rotary cutter with the side skids 1″ lower than the desired cut height. For example, for a 3″ cut, position the skids 2″ from the ground. Set the control lever stop at this position to maintain this height when raising and lowering the cutter.

Ironcraftusa.com

6.8 GENERAL OPERATING PROCEDURE
Although the rotary cutter is easy to use, each operator should review this section to familiarize themselves with the detailed safety and operating procedures.

1. Operate the rotary cutter only in conditions where you have clear visibility in daylight or with adequate artificial lighting. Never operate the rotary cutter in darkness or foggy conditions where you cannot clearly see at least 300 feet in front and to the sides of the tractor and rotary cutter. Make sure that you can clearly see and identify passersby, steep slopes, ditches, drop-offs, overhead obstructions, debris, and foreign objects. If you are unable to clearly see these type of items, discontinue operating the cutter.
2. Clear the area of bystanders, especially small children.
3. Clear the area to be cut of stones, branches, debris, and any hard objects that may be thrown. Never operate the rotary cutter in an area that you have not inspected and removed debris or foreign material. Mark the location of objects that cannot be removed.
4. Do not operate the rotary cutter, or drive the tractor into material that is burning, or areas that recently burnt and may contain hot spots. Burning material, sparks, and coals could be thrown from the rotary cutter to areas of vegetation that might ignite. Tire damage can occur when driving over hot material. Oil and grease on the tractor and rotary cutter could ignite, resulting in equipment destruction. Carry a fire extinguisher on the tractor at all times to extinguish possible fires encountered. Do not operate the rotary cutter on a tractor with an underframe exhaust.

5. Raise the rotary cutter fully and remove the transport lock. Fasten the transport lock around a leveling rod to prevent its loss. Lower the rotary cutter to operating height.
6. Remove the wing uplock pins and replace them in the storage location. Lower the wings.
7. Engage the PTO at low engine RPM, then raise PTO speed to 540 or 1000 RPM, as appropriate.
8. Begin cutting at a slow speed, then increase to a speed that gives a clean cut without lugging the engine. Do not operate above 5 MPH.
9. Never allow blades to contact solid objects like rocks, posts, wire, curbs, guardrails, or the ground while mowing.
10. When you get to the end of a pass, slightly raise the rotary cutter (2-4″) before turning. Never raise the rotary cutter entirely while the blades are turning. If the rotary cutter must be raised higher than 12″ from ground level, disengage the tractor PTO and wait for all blade rotation to come to a complete stop before proceeding to raise the rotary cutter.
11. When turning, the angle between the tractor and rotary cutter must not exceed 80°. This extreme angle is intended for intermittent use only. Plan your cutting to minimize extreme turning angles. Sharp turns can cause premature failure of the joints and put pressure on the tractor PTO shaft, and could cause extensive mechanical damage to the rotary cutter and tractor.

OPERATION

43

Ironcraftusa.com

12. Large, dense, or wet vegetation may need to be cut in two or more passes to achieve a uniform cut. In such conditions, raise the cutting height to 12″ or more on the first pass. Then lower the rotary cutter to the desired height and mow the vegetation a second time. If possible, select a cutting direction that is at a 90 degree angle to the first pass to reduce streaking for a more uniform cut.
13. Stay alert and watch for trees, low hanging limbs, power lines, and other overhead obstacles while operating. Use care to avoid hitting these items.
14. Avoid cutting in reverse. Instead, disengage the PTO, wait for the blades to stop, and raise the deck. Back up into the area to be cut. Lower the deck, engage the PTO, and cut forward. Do not back the rotary cutter into solid objects. The joint where the hitch attaches to the deck will pivot upward, allowing the front edge of the deck to contact the driveline. Check to make sure there are no persons behind the

rotary cutter, and use extreme care when maneuvering in reverse.
15. Always cross steep ditches and banks at a diagonal. Never cross straight across and never back into a steep ditch or bank. Cutting over ditches and backing up hills can “Bottom Out” the driveline. Bottoming out is when the driveline shaft has shortened to the point it is pressing against the gearbox and tractor PTO shafts. Once a driveline has bottomed out, it cannot be shortened anymore without causing serious damage to the tractor PTO components, cutter gearbox, and driveline.
16. Do not operate a pull-type cutter at an angle exceeding 25 degrees up or down or at any angle that will force the driveline to bind and/or hit the tractor drawbar.
17. Whenever using a rotary cutter in dry grass, be aware that a thrown metal object can create a spark against the blade or metal deck housing. Take extra precautions in this type of dry situation to prevent fires.

6.9 CHAIN SHIELDING
IronCraft installs full chain shielding as standard equipment on all flex-wing rotary cutters.

WARNING
PROJECTILE HAZARD
The chain shielding is designed to reduce the risk of thrown objects.
The rotary cutter deck and protective devices cannot prevent all objects from escaping the blade enclosure in every mowing condition. It is possible for objects to ricochet and escape, traveling as much as 300 feet.
Death or serious injury can result from being struck by a thrown object. Do not operate the cutter if the chain shielding is missing or damaged.

1. Full chain shielding must be installed when operating in populated areas or other areas where thrown objects could injure people or damage property.
2. If the chain shielding is missing or damaged, operation must be stopped until it can be repaired or replaced.
3. Inspect chain shielding each day of operation and replace any broken or missing chains, as required.

44

Ironcraftusa.com

6.10 RIGHT OF WAY (ROADWAY) MOWING
Use double chain guards for highway, right-of-way, parks, greenbelt mowing, or all other mowing where human dwellings, vehicles, or livestock could be within 300 feet of the cutter.
NO SHIELDING IS 100% EFFECTIVE IN PREVENTING THROWN OBJECTS. TO REDUCE THE POSSIBILITY OF INJURY:
1. Maintain rotary cutter shielding in good operational condition.
2. Inspect the condition of the thrown object guards, cutter side skirts, and skid shoes daily: Replace or repair worn or damaged guards.
3. Inspect the condition of the blades and blade bolts daily. Replace any cracked, worn, bent or damaged blades. Always replace blade bolts and lockwashers when replacing blades. Make sure the blade bolts are properly tightened.
4. Raise cutting height to 6″ minimum.
5. Never allow blades to contact solid objects like rocks, posts, wire, curbs, guardrails, or the ground while mowing.
ROTARY CUTTERS CAN THROW OBJECTS 300 FEET OR MORE UNDER ADVERSE CONDITIONS.
1. To avoid serious injury or death from thrown objects, inspect the area thoroughly for potential thrown objects and remove them before cutting.
2. Remove debris, rocks, wire, cable, metal objects, and other foreign material from area.
3. Wire, cable, rope, chains, and metal objects can be thrown or swung outside the deck with great velocity.
4. Mark the location of objects that cannot be removed.
STOP MOWING IF PASSERSBY ARE WITHIN 300 FEET UNLESS:
1. All thrown object shielding including front and rear deflectors, chain guards, steel guards, bands, side skirts, and skid shoes are in place and in good condition when mowing.
2. Mower sections or wings are adjusted to be close and parallel to ground without exposing blades.
3. Mowing area has been inspected and foreign materials and debris have been removed.
4. Passersby are inside an enclosed vehicle.

9.6 BLADE SERVICING

Inspect blades before each use to determine that they are properly installed and in good condition. If any blade is bent, excessively nicked, worn, or has any other damage, replace both blades on the spindle. Small nicks can be ground out when sharpening. Manually rock the blade carriers to check for any looseness. Recheck torque every fifty hours. Retighten any loose parts.

9.6.1 BLADE REMOVAL

9.6.2 BLADE INSTALLATION

To remove the blades for sharpening or replacement, remove the nut and lockwasher from the blade bolt through the inspection hole in the deck of the mower near the gearbox.

When installing blades, be sure to check the blade bolt pivot diameter for wear. Replace the bolt if worn more than 1/4 inch at any point. Tighten nut to 600 ft. lbs.

Always use a new lockwasher and nut when replacing the blade bolt.

9.6.3 BLADE SHARPENING

Make sure blades are installed with the cutting edge in the direction of rotation. The left and center spindles rotate counterclockwise as viewed from above the deck. The right spindle rotates clockwise as viewed from above the deck.

CAUTION
SHARP OBJECT HAZARD
The grinder may catch on the blade during sharpening, propelling it forcefully. To prevent the possibility of serious injury, make sure blades are secured against movement while sharpening.

When sharpening blades, always sharpen both blades at the same time and grind the same amount on each blade to maintain balance. Unbalanced blades will cause excessive vibration, which can damage gearbox bearings. Vibration may also
FOLLOW ORIGINAL PATTERN

cause structural cracks to the rotary cutter. Follow the original sharpening pattern. Do not sharpen blades to a razor edge, leave a 1/16″ blunt edge. Do not sharpen the back side of the blade. Do not heat and pound out the edge.

9.7 BLADE CARRIER REMOVAL

1. Remove the cotter pin and loosen the castle nut on the gearbox shaft. Do not remove the nut until the blade carrier is loosened.
2. Use a suitable two jaw gear puller to pull the carrier off the tapered gearbox shaft.

3. If a gear puller is not available, insert a bar through the blade bolt access the hole with the end against the blade carrier. Strike the opposite end of the bar sharply. Rotate the blade carrier 180 degrees and repeat until the carrier breaks loose.
4. Remove the castle nut and the blade carrier.

9.8 BLADE CARRIER INSTALLATION

1. Clean the splines on both the blade carrier and the output shaft.
2. Position the carrier on the gearbox output shaft and install the castle nut. Tighten the nut to a minimum 450 ft. lbs.

3. Strike the carrier near the hub several times with a heavy hammer to seat the hub. Use care not to strike the nut or the end of the shaft.
4. Retighten the nut to 700 ft. lbs.
5. Install the cotter pin and spread the tangs.

9.9 SLIP CLUTCH OPERATIONAL CHECK

The rotary cutter is equipped with three slip clutches, with one located in front of each spindle gearbox. The slip clutches serve as overall protection for the tractor, driveline, and gearboxes. Even though new clutch assemblies are “run-in” and checked for torque prior to shipment, readjustment may be advisable if the clutch has been exposed to weather for an extended period of time. The clutch facing and plates should be inspected for rust and/or corrosion. After the rotary cutter has been stored for thirty days or more, perform the following check:

1. Make a trial run in the heaviest operating conditions expected. If any clutch slips noticeably, tighten the eight adjusting bolts no more than 1/2 turn between trial runs until the clutch slippage is reduced.

2. Scribe a mark across the clutch facing of each slip clutch. When subjected to shock loads, a separation of the marks will assure that the clutch setting is correct.

NOTICE
Check the clutches periodically during the first hour of operation for excessive heat build-up due to unexpected slippage.

SERVICE AND MAINTENANCE

Ironcraftusa.com

If a clutch is being rebuilt (new facing and/or plates), it is necessary to “run-in” these parts prior to final adjustment. The plates should be thoroughly cleaned and free of foreign material, as well as being checked for warping with a straight edge. Warped plates cannot be adjusted properly and will
not hold. To accomplish the “run-in” after assembly, follow this procedure:

1. Tighten all the adjusting bolts evenly until the clutch cannot be slipped by hand.
2. With the blade carrier locked in a stationary position, operate with the PTO at idling speed (approximately 100 RPM), until evidence of heating is noted. Do not allow the clutch to overheat.

3. Discontinue operation and allow the clutch to cool completely.
4. After the clutch has cooled, tighten all the adjusting bolts evenly and proceed with the regular clutch adjusting procedures, as described above.

9.10 SLIP CLUTCH ADJUSTMENT
The slip clutches are factory preset to the correct torque for protecting the implement and tractor. Periodic adjustment is recommended. Should adjustment be needed, follow this procedure:

1. Check to be sure all spring lengths are the same. Initial spring length is shown in the chart.
2. If necessary, adjust the nut on any spring that is unequal. Adjust all eight spring retaining nuts 1/3 of a turn (two flats on a nut) and check clutch slippage.
3. If further adjustment is necessary, adjust in 1/3 turn increments. Adjust only to provide sufficient torque to prevent slippage under normal conditions. Occasional slippage is normal for drive train protection. If satisfactory results cannot be obtained, consult your authorized dealer.
