the key from the ignition before removing the obstruction. • Cut grass slopes carefully. Do not start, stop, or turn suddenly. • Do not touch the engine or muffler while the engine is running or soon after it has stopped because these areas could be hot enough to cause burns. Maintenance and Storage • Check the blade mounting bolts frequently to be sure that they are tightened to specification.

inch (13 mm). That is the back of the blade plane is 1/2 inch (13 mm) higher than the front. 1. Position the machine on a level surface on the shop floor. 2. Set the cutting unit to the desired height-of-cut. 3. Rotate 1 blade so that it points straight forward. 4. Using a short ruler, measure from the floor to the front tip of the blade. Rotate the blade tip to the rear and measure from the floor to the tip of the blade. Figure 12 5.

Check and adjust all castor tire pressures to 50 psi (3.4 BAR). Select the Proper Height-of-Cut Setting to Suit Conditions 4. Check for bent blades; refer to Checking for a Bent Blade. Remove approximately 1 inch (25 mm) or no more than 1/3 of the grass blade when cutting.

Tilting the Cutting Unit for Maintenance To prepare the unit for maintenance: 1. Position the machine on a level surface, raise the cutting unit, turn off the engine, engage the parking break, and apply the lift arm latches. g017953 Figure 16 Note: If the cutting unit is a 72 inch (183 cm) model with a rear discharge kit fitted, the rear LH foot guard should be removed prior to carrying out this operation. 2.
lift arm pads. Repeat for the LH side, making sure the RH side height-of-cut rod does not fall out (Figure 19). 4. Install the height-of-cut collars onto the height-of-cut rods and secure them with the clevis pins and hair pin cotters (Figure 19). Make sure the head of the clevis pin is toward the front of the deck. 1 Separating the Cutting Unit from the Traction Unit 2 3 g017958 4 Figure 21 1.
pin cotters (Figure 23). Head of clevis pin to be positioned toward the front of the deck. 2. Move the cutting unit into position in front of the traction unit. 3. Install the hydraulic motor onto the cutting unit, secure it using the two bolts, then install the two hydraulic motor covers (Figure 22). 4. Move the lift switch to the Float position.
Grasp the castor wheel and slide the bolt out of the fork or pivot arm. G010549 Figure 26 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 inch (3 mm). If the dimension exceeds 1/8 inch (3 mm), replace the blade because it is bent; refer to Removing the Cutting Blade. Removing and Installing the Blade(s) Figure 25 1.
Inspecting and Sharpening the Blade(s) DANGER A worn or damaged blade can break, and a piece of the blade could be thrown into the operator's or bystander's area, resulting in serious personal injury or death. Figure 28 • Inspect the blade periodically for wear or damage. 1. Cutting edge 3. Wear/slot forming 2. Curved area/sail 4. Crack • Do not try to straighten a blade that is bent. • Never weld a broken or cracked blade.
Checking and Correcting Mismatch of Blades 1. Lower the cutting unit to the shop floor. Remove the belt covers from the top of the cutting unit and set the covers aside. 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. 1. Using a 3 foot (1 meter) long carpenters level, find a level surface on the shop floor. 2.
