Danger 1 If the engine is started and the PTO shaft is allowed to rotate, serious injury could result. Do not start the engine and engage the PTO lever when the PTO shaft is not connected to the gear box on the cutting unit. Installing the Rear Shields 2 (Models 30369 and 30367 only) 3 1. Mount the rubber deflector to the left rear corner of the cutting with a hold down, (2) 5/16 x 1 in. lg. carriage bolts and flange nuts. Position the deflector as shown in figure 1. 4 Figure 2 1. L.H. foot shield 2.
6. Mount the rear deflector to the rear of the cutting unit with (3) 5/16 x 1–1/4 in. lg. carriage bolts and flange nuts. Position the deflector as shown in figure 4. 2. Slide the spacers onto the castor spindle to get the desired height-of-cut; refer to figure 11 to determine the combinations of spacers for the setting.. Slide a thrust washer onto the spindle, push the castor spindle through the castor arm.
Connecting the Lift Arms to the Cutting Unit 6. Push down on the rear of the cutting unit and insert the height of cut rods through the lift arm pads. 7. Install the height of cut collars onto the height of cut rods and secure with the clevis pins and hair pin cotters (Fig. 7). Position the head of the clevis pin toward the front of the deck, if possible. 1. Move the cutting unit into position in front of the traction unit. 2. Move the lift lever to the Float position.
Before Operating 1. Start the engine and raise the cutting unit off the floor so that the height-of-cut can be changed. Stop the engine and remove the key after the cutting unit is raised. Caution 2. Position the castor wheel axles in the same holes in both castor forks. Refer to figure 11 to determine the correct holes for the setting. If you leave the key in the ignition switch, someone could accidently start the engine and seriously injure you or other bystanders.
Figure 11 4. Push the castor spindle through the castor arm. Install the shims (as they were originally installed) and the remaining spacers onto the spindle shaft. Install the tensioning cap to secure the assembly. 5. Remove the hair pin and clevis pin securing the height of cut collar to the height of cut rod on the rear of the cutting unit (Fig. 12). Figure 13 Note: When using 1 in. (25 mm), 1-1/2 in. (38 mm), or occasionally 2 in. (51 mm) height–of–cut, move the skids and roller to the highest holes.
Adjusting the Rollers 8. Lower cutting unit onto the flat surface. Remove the covers from the top of the cutting units Note: If the cutting unit is to be used in the 1 or 1-1/2 in. (25 or 38 mm) height-of-cut setting, the cutting unit rollers must be repositioned in the top bracket holes. 9. Rotate the blade on each spindle until the ends face forward and backward. 10. Measure from the floor to the front tip of the cutting edge. 1.
Operation Always Mow with Sharp Blades A sharp blade cuts cleanly and without tearing or shredding the grass blades like a dull blade. Tearing and shredding causes the grass to turn brown at the edges which impairs growth and increases susceptibility to diseases. Note: Determine the left and right sides of the machine from the normal operating position. Operating Tips After Operating Mow When Grass is Dry To ensure optimum performance, clean the underside of the mower housing after each use.
Maintenance Recommended Maintenance Schedule Maintenance Service Interval Maintenance Procedure After first 2 hours • Tighten the castor wheel nuts. After first 10 hours • Tighten the castor wheel nuts. • Torque the blade bolts. Daily • Check the blades. • Lubricate the castor arm bushings.1 • Lubricate the castor wheel bearings.1 Tighten the castor wheel nuts. Torque the blade bolts. Lubricate the grease fittings.1 Clean under the cutting unit belt covers. Check the blade drive belt adjustment.
Caution If you leave the key in the ignition switch, someone could accidentally start the engine and seriously injure you or other bystanders. Remove the key from the ignition switch before you do any maintenance. Figure 18 Greasing the Bearings, Bushings and Gear Box The machine has grease fittings that must be lubricated regularly with No. 2 General Purpose Lithium Base Grease.
2. Position the machine and cutting unit on a level surface and lower the cutting unit. Remove the dipstick/fill plug from the top of the gear box (Fig. 21) and make sure that the lubricant is between the marks on the dipstick. If the lubricant level is low, add SAE 80–90 wt. gear lube until the level is between the marks. 3. Remove the hairpin and clevis pin securing the height of cut collar to the height of cut rod on the rear of the cutting unit (Fig. 22). Remove the height of cut collar. 4.
Mounting the Cutting Unit to the Traction Unit 7. Start the traction unit and raise the cutting unit. 8. Push down on the rear of the cutting unit and insert the height of cut rods through the lift arm pads. 1. Position the machine on a level surface and shut the engine off. 2. Move the cutting unit into position in front of the traction unit. 9. Install the height of cut collars onto the height of cut rods and secure with the clevis pins and hair pin cotters (Fig. 25).
Servicing the Castor Arm Bushings 2. Remove the bearing from the wheel hub and allow the bearing spacer to fall out (Fig. 28). Remove the bearing from the opposite side of the wheel hub. The castor arms have bushings pressed into the top and bottom of the tube and after many hours of operation, the bushings will wear. To check the bushings, move the castor fork back and forth and from side to side. If the castor spindle is loose inside the bushings, the bushings are worn and must be replaced. 3.
3. Rotate the opposite end of the blade forward. Measure between the cutting unit and cutting edge of the blade at the same position as in step 2. The difference between the dimensions obtained in steps 2 and 3 must not exceed 1/8 in. (3 mm). If the dimension exceeds 1/8 in. (3 mm), the blade is bent and must be replaced; refer to Removing the Cutter Blade, page 22. Important The curved part of the blade must be pointing toward the inside of the cutting unit to ensure proper cutting.
Correcting Cutting Unit Mismatch Note: Remove the blades and sharpen them on a grinder. After sharpening the cutting edges, install the blade with the anti-scalp cup and blade bolt; refer to Removing and Installing the Cutter Blade(s), page 22. If there is mismatch between the blades, the grass will appear streaked when it is cut. This problem can be corrected by making sure that the blades are straight and all of the blades are cutting on the same plane. FLAT PART OF BLADE A SAIL 1.
Replacing the Drive Belt 4. Route the new belt around the spindle pulleys and idler pulley assembly as shown in figure 35. The blade drive belt, tensioned by the spring loaded idler pulley, is very durable. However, after many hours of use, the belt will show signs of wear. Signs of a worn belt are: squealing when belt is rotating, blades slipping when cutting grass, frayed edges, burn marks and cracks. Replace the belt if any of these conditions are evident. 1. Lower the cutting unit to the shop floor.
