To steer the mower to the right while traveling forward, allow the right steering control lever to move back toward the neutral position. The further the steering control is allowed to move back, the quicker the mower will turn right.
To stop the forward travel completely, allow the steering control levers to return to the neutral position. If the mower is to be parked, engage the parking brake.
– NOTE Smooth operation of the steering control levers will produce smooth mower operation. While learning the operation of the steering controls, keep the travel speed low.
– IMPORTANT Do not travel forward over a curb. The mower will hang up on the curb. Raise the deck and travel backwards over the curb at a 45 degree angle.
REVERSE TRAVEL
CAUTION
Disengage power to the mower before backing up. Do not mow in reverse unless absolutely necessary and then only after observation of the entire area behind the mower.

– NOTE The mower may not travel straight in reverse. Slight adjustments may need to be made using the steering controls.
To steer left while traveling in reverse, allow the left steering control lever to move forward. The further the control is allowed to move forward, the quicker the mower will turn left.
To steer right while traveling in reverse, allow the right steering control lever to move forward. The further the control is allowed to move forward, the quicker the mower will turn right.
To stop the reverse travel, allow the steering control levers to return to the neutral position. If the mower is to be parked, engage the parking brake.
4.8 ENGAGING THE DECK DRIVE (CUTTER BLADES)
1. Set the throttle at about 3/4 speed. Do not attempt to engage the deck drive at high speed as this shortens the electric clutch life — use only moderate engine speed when engaging the deck drive.
2. Engage the deck drive by pulling out on the yellow switch, located on the instrument panel, to the engage position. See Figure 4-5.

CAUTION
Before backing up, observe the rear for persons and obstructions. Clear the area before backing up. Possible injury or property damage could occur.
To travel in reverse, use the rear reference bar as an anchor for your hands, and slowly pull both steering control handles back. Keep the travel speed low while traveling in reverse. See Figure 4-4

CAUTION
Disengage power to the mower before backing up. Do not mow in reverse unless absolutely necessary and then only after observation of the entire area behind the mower.
CAUTION
Before backing up, observe behind the mower for persons and obstructions. Clear the area before backing up. Possible injury or property damage could occur.
– NOTE A squealing noise may be heard when engaging or disengaging the deck drive. It is caused by the electric clutch plates meshing as the mower comes up to speed. This is normal.
3. To disengage the deck drive, push the switch in to the disengage position.
4. Always operate the engine at full throttle to properly maintain cutting speed. If the engine starts to lug down, reduce the forward speed and allow the engine to operate at maximum RPM.
4.9 HILLSIDE OPERATION
WARNING
DO NOT operate on steep slopes. Under no circumstances should the machine be operated on slopes greater than 20 degrees. See Figure 2-1, Page 6 to determine approximate slope of area to be mowed. ALWAYS FOLLOW OSHA APPROVED OPERATION.

2. Stay at least 2 cutting widths away from drop-offs, ditches, retaining walls, water, avoid any slope exceeding 20-degrees.
3. To prevent tipping or loss of control, do not start or stop suddenly, avoid unnecessary turns and travel at reduced speed. If tires lose traction, disengage blades and proceed slowly off the slope.
4. Avoid sudden starts when mowing uphill. Sudden starts may cause the machine to tip backwards.
5. Loss of traction may occur when traveling down hill. Weight transfers to the front of the machine and may cause the drive wheels to slip causing loss of braking or steering.
6. Never back down a hill.
7. Keep tires properly inflated.
4.10 PARKING THE MOWER
1. Park the machine on a flat, level surface only. Do not park the machine on an incline.
2. Place the steering control levers in the neutral position.
3. Disengage the cutter blades.
4. Slow the engine to idle speed.
5. Engage the parking brake.
6. Turn the ignition key to the OFF position and remove the key.
4.11 AFTER OPERATION
1. Wash the entire mower after each use. Do not use high pressure spray or direct the spray onto electrical components.
– IMPORTANT Do not wash a hot or running engine. Cold water will damage the engine. Use compressed air to clean the engine if it is hot.
2. Keep the entire mower clean to inhibit serious heat damage to the engine or hydraulic oil circuit.
3. Check the drive belts for proper alignment and any signs of wear. Correct and adjust if necessary.

1. This mower has been designed for good traction and stability under normal mowing conditions. However, caution must be used when traveling on slopes, especially when the grass is wet. Wet grass reduces traction and steering control.

DANGER
To avoid injury from burns, allow the mower to cool before removing the fuel tank cap and refueling.

WARNING
DO NOT operate without Discharge Chute, Mulching Kit, Operator Controlled Discharge Chute (OCDC) or entire Grass Catcher properly installed.

4. After the mower has cooled down, fill the fuel tank with fresh, clean fuel at the end of every day of operation. See Engine Owner’s Manual for proper octane requirements.
5. Check the tire pressure. Adjust pressure if necessary.
4.12 REMOVING CLOGGED MATERIAL
DANGER
ROTATING BLADES
NEVER PUT YOUR HANDS INTO THE DISCHARGE CHUTE FOR ANY REASON!
Shut off the engine and remove the key and only then use a stick or similar object to remove material if clogging has occurred.
1. If the discharge chute becomes clogged, shut off the engine and remove the ignition key. Using a stick or similar item, dislodge the clogged material. Then resume normal mowing.
4.13 MOVING MOWER WITH ENGINE STOPPED

2. The discharge chute must not be removed and must be kept in the lowest position to deflect grass clippings and thrown objects downward. Direct the side discharge away from sidewalks or streets to minimize cleanup of clippings. When mowing close to obstacles, direct the discharge away from the obstacles to reduce the chance of property damage by thrown objects.
3. Cut grass when it is dry and not too tall. Do not cut grass too short (cut off 1/3 or less of existing grass for best appearance). Mow frequently.
4. Keep mower and discharge chute clean.
5. When mowing wet or tall grass, mow the grass twice. Raise the mower to the highest setting for the first pass and then make a second pass to the desired height.
6. Use a slow travel speed for trimming purposes.
7. Operate the engine at full throttle for best cutting. Mowing with a lower RPM causes the mower to tear the grass. The engine is designed to be operated at full throttle.
8. Use the alternate stripe pattern for best lawn appearance. Vary the direction of the stripe each time the grass is mowed to avoid wear patterns in the grass.
4.15 ADJUSTING CUTTING HEIGHT
The mower deck can be adjusted from a height of 1-1/2 inch to 4-1/2 inches at 1/4-inch intervals. To adjust the cutting height:

To “free-wheel” or move the mower around without the engine running, place the dump valve levers in the FREEWHEEL position. Disengage the parking brake and move the mower by hand. The dump valve levers must be returned to the DRIVE position and torqued to 7-10 ft/lbs to drive the mower.
4.14 RECOMMENDATIONS FOR MOWING
1. Do not mow with dull blades. A dull blade will tear grass, resulting in poor lawn appearance and reduced mowing power.

WARNING
DO NOT adjust the cutting height with the mower blades rotating. Disengage the power to the cutter blades, put the steering control levers in the neutral position, apply the parking brake and then adjust cutting height.
1. Disengage the power to the cutter blades. 2. Pull the cutter deck lift lever all the way backward until it locks in
place. See Figure 4-6.
3. Insert the lanyard pin into the cutting height index at the desired cutting height. Pull backward on the cutter deck lift lever, push and hold the lock button See Figure 4-6. Slowly release the cutter deck lift lever. A deck height decal is located on the cutting height index as an aid in adjusting the deck to the desired height.

5. Repeat for the RH wheel using the same adjustment procedure listed above.

The engine and drive unit can get hot during operation causing burn injuries. Allow the engine and drive components to cool before making any adjustments.

NOTE

Before proceeding with this adjustment, be sure that the caster wheels turn freely and that the tire pressure in the drive wheels is correct. If the tire pressure is not correct, the machine will pull to the side with the lower pressure.
1. If at full speed the mower pulls right, it is an indication that the left wheel is turning faster than the right wheel. To adjust this condition, proceed as follows:
A. Stop the machine and place the steering control levers in the neutral position. Loosen the lock nuts securing the ball joints at each end of the LH steering control rod. Rotate the control rod to lengthen the rod and tighten the lock nuts. This will cause the control rod to stroke the LH pump less, slowing down the LH wheel. See Figure 6-2.

NOTE
If after making the adjustment as outlined in step 1A, the machine creeps forward or backward, the neutral adjustment must be made as described.
2. If at full speed the mower pulls left, it is an indication that the right wheel is turning faster than the left wheel. To adjust this condition, proceed as follows:
A. Stop the machine and place the steering control levers in the neutral position. Loosen the lock nuts securing the ball joints at each end of the RH steering control rod. Rotate the control rod to lengthen the rod and tighten the lock nuts. This will cause the control rod to stroke the RH pump less, slowing down the RH wheel. The same adjustment is used for the RH side as shown in Figure 6-2.

WARNING
If the pump drive belt fails, steering control will be lost which could result in serious injury or death. Replace the pump drive belt as needed or every 400 hours / 2 years, whichever occurs first.
6.5 BELT ALIGNMENT
Belt alignment is important for proper performance of your Scag mower. If you experience frequent belt wear or breakage, see your authorized Scag service center for belt adjustment.
6.6 CUTTER DECK ADJUSTMENTS

– NOTE If after making the adjustment as outlined in step 2A, the machine creeps forward or backward, the neutral adjustment must be made as described on page 25 and 26.
6.3 THROTTLE CONTROL AND CHOKE ADJUSTMENTS
These adjustments must be performed by your Scag dealer to ensure proper and efficient running of the engine. Should either need adjustment, contact your authorized Scag service center.
6.4 BELT ADJUSTMENTS
WARNING
Before removing any guards, shut the engine off and remove the ignition key. Wait for all moving parts to come to a complete stop before beginning work.

Cutter deck level, pitch and height are set at the factory. However, if these adjustments should ever need to be made, the following procedures will aid in obtaining the proper cutter deck adjustment.
– NOTE –
Before proceeding with the cutter deck adjustments, be sure all tires are properly inflated.
CUTTER DECK LEVEL
The cutter deck should be level from side-to-side for proper cutting performance. To check for level, be sure that the mower is on a flat, level surface, the tires are properly inflated and the cutter deck is set at the most common cutting height that you will use. On the RH side of the machine, check the distance from the top of the cutter deck to the floor. Next check the distance from the top of the cutter deck to the floor on the LH side of the machine. Both measurements should be the same. If the two measurements are different, the cutter deck level must be adjusted as follows:
1. If the cutter deck is lower on one side, loosen the elastic stop nuts securing the deck level links on the front and rear of the lower side. See Figure 6-3.

All drive belts and cutter deck belts are spring loaded and self-tensioning. The belts should be checked periodically for proper alignment and wear.

Figure 6-3. Cutter Deck Level Adjustment
2. Turn the adjustment bolts on the front and rear deck level links clockwise until the cutter deck is level between both sides. See Figure 6-3.
3. Tighten the two (2) elastic stop nuts to secure the cutter deck in the proper position.
CUTTER DECK PITCH

Figure 6-4. Cutter Deck Pitch Adjustment
2. Turn the adjustment bolts on both sides either clockwise to raise or counter-clockwise to lower the front of the cutter deck until the measurements are equal. Tighten the elastic stop nuts.

The pitch of the cutter deck should be equal between the front and rear of the cutter deck for proper cutting performance. To check for proper deck pitch, be sure that the mower is on a flat, level surface and the tires are properly inflated.
Check the distance from the top of the cutter deck to the floor at the rear RH side of the cutter deck directly behind the cutter deck hanging chains. Next check the distance from the top of the cutter deck to the floor at the front RH side of the cutter deck directly in front of the cutter deck hanging chains. The measurement at the front of the cutter deck should be the same as the rear of the deck. Make these measurements at the LH side of the cutter deck also. If the measurement at the front of the deck is not the same, the cutter deck pitch must be adjusted as follows:
1. Loosen the elastic stop nuts securing the deck level links on the front of the cutter deck on both sides. See Figure 6-4 and 6-5.

7.3 HYDRAULIC SYSTEM

B. CHANGING HYDRAULIC OIL

A. CHECKING HYDRAULIC OIL LEVEL
The hydraulic oil level should be checked after the first 8 hours of operation. Thereafter, check the oil after every 200 hours of machine operation or monthly, whichever occurs first.
– IMPORTANT –
If the oil level is consistently low, check for leaks and correct immediately.
1. Remove the operator cushion as outlined in Section 6.8.
2. Wipe dirt and contaminants from around the reservoir cap. Remove the cap from the hydraulic oil reservoir.
3. Visually check the level of hydraulic oil. Hydraulic oil must be at least 2-1/4″ inches from top of the filler neck. If the level cannot be determined visually, use a clean tape measure to check the level. If the fluid is low, add 20W50 oil (Scag p/n 486255 – 1 Quart or p/n 486254 – 1 Gallon). DO NOT overfill; (overfilling the oil reservoir may cause oil seepage around the cap area).
4. Clean the fill cap and install it onto the reservoir.

The hydraulic oil should be changed after every 500 hours or annually, whichever occurs first. The oil should also be changed if the color of the fluid has become black or milky. A black color and/or a rancid odor usually indicates possible overheating of the oil, and a milky color usually indicates water in the hydraulic oil.
– IMPORTANT –
The hydraulic oil should be changed if you notice the presence of water or a rancid odor to the hydraulic oil.
1. Park the mower on a level surface, stop the engine and remove the ignition key.
2. Remove the operator cushion and rear cover as outlined in Section 6.8.

DANGER
To avoid injury from burns, allow the mower to cool before changing the oil and removing the filter.

7.5 ENGINE FUEL SYSTEM

DANGER
To avoid injury from burns, allow the mower to cool before removing the fuel tank cap and refueling.

A. FILLING THE FUEL TANK
Fill the fuel tank to the bottom of the filler neck insert (approximately 5 gallons for 32″ models, 7 gallons for 36″ models or 8 gallons for all other models indicating Full (F) on the fuel gauge) at the beginning of each operating day. See Figure 7-5. Do not overfill. Use clean, fresh unleaded gasoline with a minimum octane rating of 87 and a maximum of 10% Ethanol.
DO NOT use E85 Fuel. Using E85 Fuel will cause severe damage to the engine.

WARNING
Always wear proper hand and eye protection when working with cutter blades.
1. Remove the ignition key before replacing the blades.
2. Raise the mower deck to the highest position. Place the lanyard pin in the highest cutting height position to prevent the cutter deck from falling.
3. Secure the cutter blades to prevent them from rotating, (use the optional Blade Buddy tool, P/N 9212, to assist in securing the cutter blades), remove the nut from the blade attaching bolt. Remove the cutter blade, bolt and spacer from the spindle shaft. See Figure 7-8.
– NOTE The front of the machine will have to be raised slightly to remove the blade bolt from the cutter spindle.

CAUTION
Inspect the cutter blade spacer(s) and washer for wear and/or cupping. Replace the worn parts. Worn spacer(s) and/or washer will not allow proper tightening of the cutter blade and can lead to cutter blade failure, personal injury or property damage.
4. To install the new cutter blade, put the flat washer onto the blade bolt and slide the bolt into the hole in the cutter blade.
– NOTE Be sure that the blade is installed with the lift wing pointing toward the top of the deck.
5. Install the spacer onto the blade bolt and insert the bolt into the cutter spindle shaft.
6. Install the hex nut to the blade bolt at the top of the cutter spindle. Secure the blades from rotating and torque to 75 ft/lbs. See Figure 7-8.
