Safety 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. 93-7009 1. Thrown object hazard from mower—keep the deflector in place. 2. Cutting/dismemberment hazard of hands and feet—stay away from rotating blades and moving parts. 93-7010 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. Grass deflector 1 Spring 2 Bolt, 3/8 x 3-1/2 in. 2 Locknut, 3/8 in. 2 Gage wheel 2 Pin 2 Hairpin cotter 2 Mower mounting plate 1 Shoulder bolt 2 Locknut, 1/2 in. 2 Bolt, 5/16 x 2-1/2 in. 2 Locknut, 5/16 in.
Installing the Mower 5. Deflect the anti-rattle spring, slide the adjusting plate of the gage wheel into the mower gage wheel bracket, and secure it with the pin and hairpin cotter (Fig. 3). Danger Note: After installing the mower onto the tractor and adjusting the height-of-cut. adjust the gage wheels; refer to Adjusting the Gage Wheels, page 12.

Slide the end of the long rod through the hole in the mower mount (Fig. 8). Install the thin washer and hairpin cotter to secure the rod in place.
11. Look under tractor and take down the PTO cable nested inside the frame rail. 12. Loosen the jam nut near the end of the cable. Route the cable through the slot in the deck bracket (Fig. 9). 1 13. Hook the Z end of the PTO cable into the bellcrank arm (Fig. 9). 14. Engage the PTO lever on the dash. Measure the distance between the Z end of the cable and the mounting bracket (Fig. 9). Adjust the jam nuts so that a 3-1/2 in. (89 mm) dimension is obtained (Fig. 9). 2 3 15.
Front-to-Rear Blade Slope 3. Carefully rotate the blade(s) side to side (Fig. 11). Measure between the outside cutting edges and the flat surface (Fig. 11). If both measurements are not within 3/16 in. (5 mm), an adjustment is required; refer to steps 4 and 5. Front Check the front-to-rear blade slope any time you install the mower. Before you check the slope, set the air pressure in the front and rear tires; refer to the tractor Operator’s Manual for the correct tire pressure.
Front 2 Removing the Mower 1078 1. Park the machine on a level surface, disengage the PTO, set the parking brake, stop the engine, and remove the ignition key. 2. Move the height-of-cut lever into the “D” notch. 3. Remove the height-of-cut lift assist spring from the retaining bolt (Fig. 16), using the spring tool provided with the machine. The spring is between the frame and the right rear wheel. 3 1 4 4 1 Figure 14 1. Blade front to rear 2. Measure front blade tip 3. Measure rear blade tip 4.
13. Move the height-of-cut lever into the “D” notch. Hook the lift assist spring onto the retaining bolt for storage (Fig. 16). 1 4 Note: Do not install the lift assist spring if the rear tire chains are to be installed. 5 2 4 1 2 1801 3 4 Figure 17 1.

2 Operation Side Discharge or Mulch Grass Danger 1 Without the grass deflector, discharge cover, or complete grass catcher assembly mounted in place, you and others are exposed to blade contact and thrown debris. Contact with the rotating mower blade(s) and thrown debris will cause injury or death. 3 1852 Figure 21 • Never remove the grass deflector from the 1. Disengaged 2. Engaged mower because the grass deflector routes material down toward the turf.
Adjusting the Gage Wheels Cut 1/3 of the Grass Blade The gage wheels must be adjusted in the proper hole location for each height-of-cut position. 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. After adjusting the height-of-cut, raise the height-of-cut lever; refer to Setting the Height-of-Cut, page 11. Mowing Direction 2.
Blade Maintenance 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. 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 Maintenance Recommended Maintenance Schedule Maintenance Service Interval Each Use Maintenance Procedure • Wash the underside of the mower.
Installing the Blade(s) 4. Inspect all parts. If a defect or damage is noticed, install new parts. 1. Install the blade, curved washer, and blade bolt (Fig. 28). 4 Important The curved part of the blade must be pointing toward the inside of the mower to ensure proper cutting. 3 2. Tighten the blade nut to 40-60 ft.-lb. (54-81 N⋅m). 2 4 1 1796 3 Figure 25 1. Nut 2. Curved washer 3. Blade 4. Spindle 2 1 Sharpening the Blade(s) 1796 Figure 28 1.
Washing the Underside of the Mower 4 1 After each use, wash the underside of the mower to prevent grass buildup for improved mulch action and clipping dispersal. 2 1. Park the machine on a hard level surface, disengage the PTO, stop the engine, and remove the ignition key. 2. Attach a hose coupling to the end of the mower washout fitting and turn the water on high (Fig. 31).
Storage Warning 1. Clean dirt and chaff from the top of the mower. A broken or missing washout fitting could expose you and others to thrown objects or blade contact. Contact with blade or thrown debris contact will cause injury or death. 2. Scrape heavy buildup of grass and dirt from the underside of the mower. Then wash the mower with a garden hose. 3. Check the condition of the blade(s); refer to Servicing the Cutting Blade, page 13.
