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. 93-7282 1. Stop the engine and remove the ignition key before leaving the machine 93-7317 2. Read the Operator’s Manual. 3. Wheel height 1. Thrown object hazard—stay a safe distance from the machine. 2. Thrown object hazard, mower—keep the deflector in place. 3.
Setup Note: Determine the left and right sides of the machine from the normal operating position. Loose Parts Note: Use the chart below to identify parts used for assembly. DESCRIPTION QTY.

Loosen adjustment bolt on one side and rotate hanger bracket to raise or lower mower (Fig. 10). The mower blades must be level from side to side. Check the side-to-side level any time you install the mower or when you see an uneven cut on your lawn.
Checking the Front-to-Rear Blade Slope 1 Check the front-to-rear blade slope any time you install the mower. Before checking the slope, set air pressure in the front and rear tires to 12 psi (85 kPa). If the front blade tip is not 3/8 in. (9.5 mm) or lower than the rear blade tip, adjust the blade slope using the following instructions. 2 1. Park the machine on a level surface, disengage the power take off (PTO), set the parking brake, and turn the ignition key to off. Remove the key. 3 m-2452 2.
Lowering Attachments Operating the Power Take Off (PTO) 1. Depress the brake and/or clutch pedals to stop the machine. The power take off (PTO) engages and disengages power to the electric clutch. 2. Pull attachment lift lever rearward, to release lift pressure, and push the button on top to release the latch. Move lift lever forward to lower attachment. While the ignition key is in the run or lights positions and the power take off (PTO) is engaged, the PTO light, in the Indicator Module, will be on.

Lift switch —DOWN Adjusting the Gage Wheels The gage wheels (on certain models) must be adjusted in the proper hole location for each height-of-cut position. Adjusting the Dial-A-Height The Dial-A-Height control (Fig. 14) is used to limit the downward travel of the attachment.
Tips for Mowing Grass Long Grass Fast Throttle Setting If the grass is ever allowed to grow slightly longer than normal, or if it contains a high degree of moisture, raise the cutting height higher than usual and cut the grass at this setting. Then cut the grass again using the lower, normal setting. For best mowing and maximum air circulation, operate the engine at fast.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position.
Sharpening the Blades 3. Inspect the blades, especially the curved area (Fig. 18). If you notice any damage, wear, or a slot forming in this area (Fig. 18), immediately install a new blade. 1. Use a file to sharpen the cutting edge at both ends of the blade (Fig. 20). Maintain the original angle. The blade retains its balance if the same amount of material is removed from both cutting edges. 1 1 2 3 Figure 20 1. Sharpen at original angle m–151 Figure 18 1. Cutting edge 2. Curved area 2.
How to Grease Front 1. Disengage the power take off (PTO), set the parking brake, and turn the ignition key to off. Remove the key 2. Clean the grease fittings with a rag. Make sure to scrape any paint off the front of the fittings. 3. Connect a grease gun to the fitting. Pump grease into the fittings. 4. Wipe up any excess grease. 1 2 1 Where to Add Grease m–1078 Figure 23 1. Long blade, 16–11/32 in. 1. Lubricate the blade spindles, idler pulley arm and gage wheel bearings (Fig. 25). 2.

Hose Warning After each use, wash the underside of the mower to prevent grass build-up for improved mulch action and clipping dispersal. A broken or missing washout fitting could expose you and others to thrown objects or blade contact. Contact with thrown debris or blade contact will cause injury or death. 1.
8. Raise attachment lift all the way to the latched position. Turn the front wheels, as necessary, and slide the mower out to the the right side. 3 Note: Save all hardware, washers and hairpin cotters for use when installing deck. 2 1 Storage 1. Clean dirt and chaff from the outside of the engine’s cylinder head fins and blower housing. Also remove grass clippings, dirt, and grime from the external parts of the entire machine, especially the engine, shrouding, and the top of the mower.
Troubleshooting Problem Abnormal vibration. Blades does not rotate. Uneven cutting g height. g Possible Causes Corrective Action 1. Cutting blades is bent or unbalanced. 1. Install new cutting blades. 2. Blade mounting bolt is loose. 2. Tighten blade mounting bolt. 3. Engine mounting bolts are loose. 3. Tighten engine mounting bolts. 4. Loose engine pulley, idler pulley, or blade pulley. 4. Tighten the appropriate pulley. 5. Engine pulley is damaged. 5.
