3. Remove the wheel nuts and slide the wheel and tire assembly off of the studs. 4. Mount a lift arm to the pivot bracket with a pivot pin and a cotter pin (Figure 4). Mount the lift arm with the bend positioned outward. 2. Move the lift lever to the FLOAT position. Push a lift arm down until the holes in the lift arm line up with the holes in the castor arm bracket and the height of cut rod can be inserted into the lift arm pads (Figure 5). 3.
7. Install the height of cut collars onto the height of cut rods and secure with the clevis pins and hairpin cotters (Figure 5). Position the head of the clevis pin toward the front of the deck, if possible. 8. Install a bolt (1/2 x 3/4 inch) and a washer to top of each height of cut rod (Figure 5). 7 Greasing the Machine No Parts Required 6 Procedure Before operating the machine, it must be greased to ensure proper lubricating characteristics; refer to 7 Greasing the Machine (page 10).

Install the shims (as they were originally installed) and the remaining spacers onto the spindle shaft.
Adjusting the Skids Adjusting the Cutting Unit Pitch Mount the skids in the lower position when operating in height of cuts higher than 64 mm (2-1/2 inches) and in the higher position when operating in height of cuts lower than 64 mm (2-1/2 inches). Cutting unit pitch is the difference in height-of-cut from the front of the blade plane to the back of the blade plane. Use a blade pitch of 6 mm (1/4 inch). That is the back of the blade plane is 6 mm (1/4 inch) higher than the front. 1.
Adjusting the Rollers Note: If the cutting unit is to be used in the 25 or 38 mm (1 or 1-1/2 inch) height-of-cut setting, position the cutting unit rollers in the top bracket holes. 1. Remove the screw and nut securing the roller shaft to the deck bracket (Figure 13). 8. Lower cutting unit onto the flat surface. Remove the covers from the top of the cutting units. 9. Rotate the blade on each spindle until the ends face forward and backward. 10.
Operating Tips inside the cutting unit, cutting quality will eventually become unsatisfactory. Fast Throttle Setting/Ground Speed To reduce the risk of fire hazard, keep the engine, muffler, battery compartment, parking brake, cutting units, and fuel storage compartment free of grass, leaves, or excessive grease. Clean up any spilled oil or fuel. To maintain enough power for the machine and deck while mowing, operate the engine at the fast throttle position and adjust your ground speed for conditions.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the first 2 hours • Tighten the castor wheel nuts. After the first 10 hours • Tighten the castor wheel nuts. • Torque the blade bolts. Before each use or daily • • • • Lubricate the castor arm bushings. Lubricate the castor wheel bearings. Check the blades. Clean the cutting unit.
CAUTION If you leave the key in the ignition switch, someone could accidently start the engine and seriously injure you or other bystanders. Remove the key from the ignition before you do any maintenance. Important: The fasteners on the covers of this machine are designed to remain on the cover after removal. Loosen all the fasteners on each cover a few turns so that the cover is loose but still attached, then go back and loosen them until the cover comes free.
2. the rear of the cutting unit (Figure 20). Remove the height of cut collar. Remove the dipstick/fill plug from the top of the gearbox (Figure 19) and ensure that the lubricant is between the marks on the dipstick. If the lubricant level is low, add enough lubricant until the level is between the marks. 4. Remove the hairpin cotters and clevis pins securing the lift arms to the castor arm brackets (Figure 21). g012237 Figure 21 g010548 Figure 19 1. Dipstick/fill plug 1. Lift arm 3.
Mounting the Cutting Unit to the Traction Unit 1. 2. 3. 4. and the castor arm bracket (Figure 23). Insert end of cotter pin into the slot in the castor arm tab to retain cotter pin. Position the machine on a level surface and shut the engine off. Move the cutting unit into position in front of the traction unit. Slide the male PTO shaft into the female PTO shaft (Figure 22). Move the lift lever to the FLOAT position.
5. Apply grease to the inside and outside of the new bushings. Using a hammer and flat plate, drive the bushings into the mounting tube. 6. Inspect the castor spindle for wear and replace it if damaged. 7. Push the castor spindle through the bushings and mounting tube, slide the thrust washer and spacer(s) onto the spindle, and install the tensioning cap on the castor spindle.
1. 2. good quality-of-cut. The sail is important because it pulls grass up straight, thereby producing an even cut. However, the sail will gradually wear down during operation, and this condition is normal. As the sail wears down, the quality-of-cut will degrade somewhat, although the cutting edges are sharp. The cutting edge of the blade must be sharp so that the grass is cut rather than torn. A dull cutting edge is evident when the tips of the grass appear brown and shredded.
where the shims must be added. To raise or lower the blade, add a shim, Part No. 3256-24, between the spindle housing and the bottom of the cutting unit. Continue to check the alignment of the blades and add shims until the tips of the blades are within the required dimension. nicked. Sharpen only the top side of the cutting edge and maintain the original cutting angle to ensure sharpness (Figure 29). The blade will remain balanced if the same amount of metal is removed from both cutting edges.
3. Remove the old belt from around the spindle pulleys and idler pulley. 4. Route the new belt around the spindle pulleys and idler pulley assembly as shown in Figure 32. Storage 1. Disengage the PTO, release the traction pedal to the neutral position, and engage the parking brake. 2. Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operator’s position. 3. Allow the engine to cool before adjusting, cleaning, storing, or repairing the machine. 4.
