Specifications General Specifications Width of Cut Models 30722 and 30710 have a 71-1/2 inch (1.816 m) width of cut. Height-of-Cut Adjustable from 1 to 4 in. (25 to 102 mm) in 1/2 in. (13 mm) increments Cutter Housing Both cutter housings are made from 11 gauge (13 mm) steel and reinforced with 3-1/2 inch (89 mm) x 7 gauge (4.76 mm) channel iron. Cutting Unit Drive Gear box mounted on cutting unit is driven by PTO shaft. Power is transmitted to the blades by three B section belts.
Setup Note: Determine the left and right sides of the machine from the normal operating position. Note: Use this chart as a checklist to ensure that all parts necessary for assembly have been shipped. Without any of these parts, total setup cannot be completed. Description Qty. Use Large castor wheel assembly 2 Small castor wheel assembly 2 Belly shield 1 Belly shield hook 2 Locknut, 5/16 in. 4 Belly shield hanger 2 Capscrew, 3/8 x 1-1/4 in.
Installing the Castor Wheel Assemblies 3 1 The thrust washers, spacers, and tensioning caps have been installed on the castor wheel spindles for shipping. 2 1. Remove the tensioning caps from the spindle shafts and slide off the spacers and thrust washers (Fig. 2 and 3). 3 4 1 2 2 2 Figure 3 4 1. Tensioning cap 2. Thrust washers 3. Spacers 4. Rear castor spindle Grass Deflector (Model 30722 & 30722TE) Remove the shipping bands allowing the deflector to be lowered (Fig. 4). Figure 2 1.
Installing the Belly Shield (Model 30710 & 30710TE) 1. Position the traction unit on level surface, shut the engine off, and engage the parking brake. 2. Block up the forward end of the engine to prevent it from shifting during disassembly. 3. Remove the capscrew and flange nut securing the front engine support to the frame. Secure the belly shield hanger and engine support to the frame with a capscrew (3/8 x 1-1/4 in.) and flange nut. Repeat the procedure on the opposite side of the machine (Fig. 5).
Warning Push arms are spring loaded. Sudden release of the push arms could cause injury. Another person is required to push the arms down during installation of the ball joints or other implements. 3. Have another person push down on the left push arm. Insert a 2 x 4 in. (51 x 102 mm) block of wood between the frame and the top of the push arm (Fig. 9). Screw the ball joint into the left-hand push arm until the center of the ball joint is 2-3/8 inches (60 mm) away from the front of the push arm (Fig. 10).
Connecting the Left-Hand Push Arm to the Cutting Unit 1. Remove the capscrews, nuts, and flat washers from the push arm mount holes in the left castor arm. Warning The left-hand push arm is spring-loaded to about 150 lb. (667 N). Sudden release of the push arm could result in injury. Figure 11 1. PTO shield 2. Self-tapping screw (2) Another person is needed to push the arm down. Warning 2.
2. Mount the PTO shield over the input shaft and onto the gear box mounting plate with two self-tapping screws (Fig. 15). 3. Attach the lift chains to the lift arm and cutting unit (Fig. 15) with 6 shackles, shackle pins (3/8 x 1-1/2 in.), and cotter pins (1/8 x 3/4 in.). Adjust the chain length so that both become tight at the same time when lifting the lift arm. 4.
Before Operating Operation Checking the Lubricant in the Gear Box Note: Determine the left and right sides of the machine from the normal operating position. The use of protective equipment, such as but not limited to, for eyes, ears, feet, and head is recommended. The gear box is designed to operate on SAE 80–90 wt. gear lube. Although the gear box is shipped with lubricant from the factory, check the level before operating the cutting unit. Caution 1.
Note: A more optimum cutting appearance of the turf can be achieved in the lower heights-of-cut by lowering the rear of the cutting unit. Accomplish this by relocating the rear castor wheel axles in the upper hole of the caster forks (Fig. 19). Place the axles into the lower castor fork holes for higher height-of-cut settings where optimum cutting appearance is not required.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. 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. • Lubricate the castor wheel bearings. Every 50 hours • • • • • • Every 250 hours • Change the gear box oil.
1 Figure 22 Figure 25 1. Fill/check plug Separating the Cutting Unit from the Traction Unit 1. Position the machine on a level surface, lower the cutting unit to the shop floor, shut the engine off, and engage the parking brake. 2. Remove the self-tapping screws securing the shield to the top of the cutting unit and set the shield aside. Figure 23 3. Drive the roll pin out of the yoke and input shaft of the gear box (Fig. 26). Also, loosen the capscrews and locknuts.
7. Roll the cutting unit away from the traction unit. Danger If the engine is started and the PTO shaft is allowed to rotate, serious injury could result. Mounting the Cutting Unit to the Traction Unit 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. 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. 4.
Replacing the Blade Drive Belts 1. Raise the cutting unit and block it so that it cannot accidentally fall. 2. Remove the tensioning cap and spacers from the top of the castor spindle. 1. Lower the cutting unit to the shop floor. Remove the covers on the top of the cutting unit and set the covers aside. Loosen the idler pulleys to release the tension on the belts. 3. Pull the castor spindle out of the mounting tube.

Remove the bushing from the wheel hub and allow the bearing to fall out (Fig. 31). Remove the bushing from the opposite side of the wheel hub. 4.
Removing the Cutting Blade Inspecting and Sharpening the Blade The blade must be replaced if a solid object is hit, the blade is out-of-balance, worn, or bent. Always use genuine Toro replacement blades to ensure safety and optimum performance. Never use blades made by other manufacturers because they could be dangerous. 1. Raise the cutting unit to the highest position, shut the engine off, and engage the parking brake. Block the cutting unit to prevent it from accidentally falling. 2.
6. Rotate the blades so that the tips line up with one another. The tips of the adjacent blades must be within 1/8 inch (3 mm) of each other. If the tips are not within 1/8 inch (3 mm) of each other, proceed to step 7 and add shims between the spindle housing and bottom of the cutting unit. SHARPEN AT THIS ANGLE ONLY END VIEW 7. Remove the capscrews, flat washers, lock washers, and nuts from the outer spindle, in the area where the shims must be added. To raise or lower the blade, add a shim, Part No.
