Safety and Instruction Decals Safety decals and instructions are easily visible to the operator and are located near any area of potential danger. Replace any decal that is damaged or lost. On the Discharge Chute (Part No. 93–1122) On the Left Side and on the Discharge Chute (Part No. 92–7108) Next to the Front Wheels (Part No. 93–7282) On the Height-of-Cut Bracket (Part No. 111655) Two on the Leveler Bar (Part No. 98–3478) On the Top, Rear of the Mower (Part No.
. Lift the discharge chute and check that it is spring loaded and pivots freely to the full down position. 1 2 IMPORTANT: Discharge chute must be spring loaded in the down position. Lift the chute up to test that it snaps to the full down position. 6 1 m–3472 3 5 Figure 2 4 2 Top View m–3484 Figure 1 1. Bracket 2. Spring hook end 3. Space for spring 1. Mower belt 4.

3 4. Attach the pulley box if it is not already on the tractor. Make sure the latches on the tractor’s front Attach–A–Matic are open (Fig. 4). Then slide the pulley box into the Attach–A–Matic latches and seat it. Close the latches. 2 5 1 1 3 m–3468 Figure 5 7 1. Slots in the side mounting brackets (2) 2.

8. After the two J–pins are seated through the mower’s mounting brackets, using the attachment lift and your hand on the right front adjustable mower wheel bracket (Fig. 7), position the mower so its attachment bar fits into the mid Attach–A–Matic mount. 3 POTENTIAL HAZARD • The “scissor” formed by the mower mounting brackets and the attachment lift arm is dangerous. 1 2 WHAT CAN HAPPEN • Hands and fingers can get caught between the mower parts and the tractor and be injured.
1 2 POTENTIAL HAZARD • Components under the hood will be hot if the tractor has been running. WHAT CAN HAPPEN • Touching hot components can cause burns. HOW TO AVOID THE HAZARD • Allow the tractor to cool before performing maintenance or touching components under the hood. ÉÉÉÉ ÉÉÉÉ ÉÉÉÉ ÉÉÉÉ m–4230 Figure 11 5. Position the end of the belt into the groove of the PTO pulley (Fig. 10), making sure it is also under the pulleys in the pulley box. 1. Pulley outside diameter 2. Wide side of belt 8.
3. Pull the height–of–cut lever out to disengage it from the quadrant. 4. Adjust the height of cut to the desired level. Release the lever inward to lock into the quadrant (Fig. 14). 1 4 2 3 3 5 1 m–3458 4 Figure 12 1. Belt tension release arm 2. Belt tension indicator (2) 3. Belt tension adjustment knob 2 4.

Measure here (side to side) Adjusting Side–to–Side Blade Cut This optional adjustment is available if necessary to compensate for uneven side–to–side cut. Equalize side–to–side cut by adjusting the two carriage bolts (Fig. 17) on the mower. Check height of blade at outside blade tips as shown (Fig. 15). 4.
Adjusting the Blade Slope for Transport Because the attachment lift is used when the PTO drive is engaged, blade slope in transport must be adjusted to extend PTO drive belt life. This adjustment also provides for adequate transport height. Three steps accomplish this: 1) Making sure the lift arm cams are in the same position, 2) Measuring blade slope in its front and rear positions and 3) Making adjustments if the blade slope is not within specification.
2. Get off the tractor. Place the mower height–of–cut lever in the lowest cut position. 1 3. Lower the deck until its weight is completely on its wheels, not on the tractor. 4. Turn the ignition key to “STOP” to stop the engine. Remove the ignition key. 5. Remove the grille. m–3454 POTENTIAL HAZARD • Components under the hood will be hot if the tractor has been running. Figure 20 1. PTO pulley WHAT CAN HAPPEN • Touching hot components can cause burns. 8. Replace the grille.
Operation Side Discharge The mower has a hinged discharge chute that disperses clippings to the side and down toward the turf. 1 POTENTIAL HAZARD • Without the discharge chute or complete grass catcher assembly mounted in place, you and others are exposed to blade contact and thrown debris. m–3456 Figure 22 1. J–pin WHAT CAN HAPPEN • Contact with rotating mower blade(s) and thrown debris will cause injury or death. 11.
IMPORTANT: For best performance, always use full throttle when the power take off (PTO) switch is ON. 2. Push the attachment lift lever downward to lower the attachment. 3. Pull the power take off (PTO) switch to ON (Fig. 24). 1 2 1 m–3264 Figure 24 1. Push (off-disengaged) m–3258 2. Pull (on-engaged) Figure 25 1.

the best one to use. When cutting grass longer than six inches tall, you may want to cut the lawn twice to assure an acceptable quality-of-cut. 2 Cut 1/3 of the Grass Blade 3 It is best to cut only about 1/3 of the grass blade. Cutting more than that is not recommended, unless grass is sparse or it is late fall when grass grows more slowly. 1 Mowing Direction 1233 Alternate mowing direction to keep the grass standing straight.
Blade Maintenance 1. With the blade(s) “ENGAGED,” move onto a previously cut area. Maintain a sharp blade throughout the cutting season because a sharp blade cuts cleanly without tearing or shredding the grass blades. Tearing and shredding turns grass brown at the edges, which slows growth and increases the chance of disease. Every 30 days, check the cutter blade(s) for sharpness and file down any nicks. 2.
Removing the Blade 1. Remove the mower; refer to Removing the Mower, page 10. POTENTIAL HAZARD • A blade that is worn or damaged could break apart and pieces could be thrown at bystanders or at you as you use the mower. 2. Carefully tip the mower over. 3. Hold the blade end using a rag or thickly padded glove. Remove the bolt, stiffener, and blade (Fig. 30). A block of wood may be wedged between the blade and the mower to lock the blade when you are removing the bolt.
How to Grease 1. Disengage the power take off (PTO), set the parking brake, lower the attachment lift, and turn the ignition key to “STOP” to stop the engine. Remove the ignition key. 2 1 Figure 32 1. Blade 2. Clean the grease fittings with a rag. Make sure to scrape any paint off the end of the fitting(s). 2. Balancer 3. Connect a grease gun to the fitting. Pump grease into the fittings. Installing the Blade(s) 4. Wipe up any excess grease. 1. Hold the blade end using a rag or thickly padded glove.
Blade Drive Belt 3. Once the indicators are in the same position on both sides, swing the tension release arm into the pulley box by moving it into the position shown in Fig. 35. Removing the Blade Drive Belt 1. Remove the mower; refer to Removing the Mower, page 10. 2. Remove the pulley cover mounting screws and pulley covers from the blade pulleys (Fig. 36). 3. Release the spring (Fig. 36). 4 2 4. Remove the belt from the pulleys (Fig. 36). 3 Installing the Blade Drive Belt 5 1 1.
9. Run the mower again for one to three minutes to remove excess water. 7. Store the machine in a clean, dry garage or storage area. Remove both the ignition and “Key Choice” keys and keep them in a memorable place. Cover the machine to protect it and keep it clean. 1 Washing the Underside of the Mower 3 After each use, wash the underside of the mower to prevent grass build-up for improved mulch action and clipping dispersal. 2 1. Park the tractor on a hard level surface. 2.
PROBLEM Blade(s) does not rotate. POSSIBLE CAUSES CORRECTIVE ACTION 1. Blade drive belt is worn, loose or broken. 1. Install new blade drive belt. 2. Blade drive belt is off pulley. 2. Install blade drive belt and check idler pulley and belt guides for correct position. 3. PTO belt is worn, loose or broken. 3. Install new PTO belt. 1. Tire pressure is incorrect. 1. Set tire pressure. 2. Mower is not level. 2. Level mower from side-to-side and front-to-rear. 3. Underside of mower is dirty. 3.
