Safety • Do not operate the mower without either the entire grass catcher or the guard in place. • Be alert, slow down and use caution when making turns. Look behind and to the side before changing directions. • Never leave a running machine unattended. Always turn off blades, set parking brake, stop engine, and remove key before dismounting. • Turn off blades when not mowing.
• Reduce speed and use extreme caution on slopes. • Do not make sudden turns or rapid speed changes. • Use a walk behind mower and/or a hand trimmer near drop-offs, ditches, steep banks or water. • Remove or mark obstacles such as rocks, tree limbs, etc. from the mowing area. Tall grass can hide obstacles. • Avoid sudden starts when mowing uphill because the mower may tip backwards. • Be aware that loss of traction may occur going downhill.
• Keep the nozzle in contact with the rim of the fuel tank or container opening at all times until the fueling is complete. Do not use a nozzle lock-open device. • Engine exhaust contains carbon monoxide, which is an odorless, deadly poison that can kill you. Do not run engine indoors or in an enclosed area. • If fuel is spilled on clothing, change clothing immediately. • Stop the engine, disconnect spark plug wire(s) and remove key before performing any service, repairs, maintenance or adjustments.

Rubber seal Cleaning the Cooling System Fuel System Maintenance Clean the air intake screen from grass and debris before each use.
Note: Now is the best time to install a new fuel filter because the fuel tank is empty. Electrical System Maintenance Spark Plug Check the spark plug(s) after every 200 operating hours. Make sure that the air gap between the center and side electrodes is correct before installing the spark plug. Use a spark plug wrench for removing and installing the spark plug(s) and a gapping tool/feeler gauge to check and adjust the air gap. Install a new spark plug(s) if necessary. Figure 28 1. Fuel lter 2.
Checking the Spark Plug charged. Use a paper towel to clean the battery case. If the battery terminals are corroded, clean them with a solution of four parts water and one part baking soda. Apply a light coating of grease to the battery terminals to prevent corrosion. 1. Look at the center of the spark plug(s) (Figure 30). If you see light brown or gray on the insulator, the engine is operating properly. A black coating on the insulator usually means the air cleaner is dirty.
Checking the Electrolyte Level 5. Slide the rubber cover up the positive (red) cable. Disconnect the positive (red) cable from the battery post (Figure 31). 6. Remove the battery hold-down (Figure 31) and lift the battery from the battery tray. Battery electrolyte contains sulfuric acid which is a deadly poison and causes severe burns. • Do not drink electrolyte and avoid contact with skin, eyes or clothing. Wear safety glasses to shield your eyes and rubber gloves to protect your hands.
Note: Do not run the tractor with the battery disconnected, electrical damage may occur. 4. Slowly pour distilled water into each battery cell until the electrolyte level is up to the Upper line (Figure 32) on the battery case. Servicing the Fuses Important: Do not overfill the battery because electrolyte (sulfuric acid) can cause severe corrosion and damage to the chassis. Service Interval/Specification The electrical system is protected by fuses.
Before Inspecting or Servicing the Blades uneven cut. Check the pressure at the valve stem after every 50 operating hours or monthly, whichever occurs first (Figure 35). Check the tires when they are cold to get the most accurate pressure reading. Park the machine on a level surface, disengage the PTO, and set the parking brake. Stop the engine, remove the key, and disconnect the spark plug wire(s) from the spark plug(s).
blades made by other manufacturers may result in non-conformance with safety standards. Hold the blade end using a rag or thickly-padded glove. Remove the blade bolt, curved washer, stifener and blade from the spindle shaft (Figure 39). Figure 37 Figure 39 1. 2. 3. Figure 38 Sail area of blade Blade Curved washer 4. 5. Blade bolt Stifener Sharpening the Blades 1. Use a file to sharpen the cutting edge at both ends of the blade (Figure 40). Maintain the original angle.
Installing the Blades 1. Install the blade onto the spindle shaft with the stiffener (Figure 39). 5. Remove the hairpin cotter and washer from the leveling bracket (Figure 43). To level the blade(s), reposition the leveling bracket(s) in a different hole and install the washer and hairpin cotter. (Figure 43). A front hole lowers the blade height and a rear hole raises its height. Adjust both sides as required.
pin from the end of the rod (Figure 44), loosen the jam nut, and turn the yoke until the 11-1/2 inch (29.3 cm) dimension is obtained. 10. To adjust the front-to-rear blade slope, remove the hairpin cotter from the front trunion yokes and loosen the jam nuts (Figure 46). 7. Then secure the yoke with the clevis pin and cotter pin. Repeat this procedure on the opposite side of the mower. Figure 46 1. 2. Figure 44 1. Rear trunion rod 2. Clevis pin and cotter pin 3. 4.
5. Remove the hairpin cotter and clevis pin from the front trunion yokes (Figure 47). Check the belts for cracks, frayed edges, burn marks, or any other damage. Replace damaged belts. Squealing when the belt is rotating, blades slipping when cutting grass, frayed belt edges, burn marks, and cracks are signs of a worn mower belt. Replace the mower belt if any of these conditions are evident. Replacing the Mower Belt Figure 47 1. Hairpin cotter and clevis pin 2. 1.
Replacing the Grass Deector Note: Check to ensure that the length of exposed thread on the spring eye bolt is 1/8 in. (3 mm) (Figure 49). An uncovered discharge opening could allow the lawn mower to throw objects in the operator’s or bystander’s direction and result in serious injury. Also, contact with the blade could occur. Never operate the lawn mower unless you install a cover plate, a mulch plate, or a grass chute and catcher. 1.
Note: It may be helpful to press down near the end of the bolt with a 9/16 inch open end wrench to align the bolts with the second holes on the mower bracket and grass deflector. 5. Lift the grass deflector and check that it is spring loaded and pivots freely to the full down position. 5. Lower the mower to the lowest height-of-cut. 6. Sit on the seat and start the engine. Engage the PTO and let the mower run for one to three minutes. 7. Disengage the PTO, stop the engine, and remove the ignition key.
Storage C. Restart the engine and run it until it stops. D. Choke or prime the engine. Start and run the engine until it will not start. Operate the primer, if equipped, several times to ensure no fuel remains in the primer system. Cleaning and Storage 1. Disengage the PTO, set the parking brake, stop the engine, and remove the key. E. Dispose of fuel properly. Recycle as per local codes. 2. Remove grass clippings, dirt, and grime from the external parts of the entire machine, especially the engine.
