If the PTO engages, there is a malfunction in the interlock system that should be corrected before beginning operation. 1 4.
Operating Characteristics Important If the machine must to be pushed or towed in reverse, the check valve in the four-wheel drive manifold must also be bypassed. To bypass the check valve, connect a hose assembly (Hose Part No. 95-8843, Coupler Fitting No. 95-0985 [Qty. 2], and Hydraulic Fitting No. 340-77 [Qty. 2]) to the reverse traction pressure test port (Fig. 29) and the reverse four-wheel drive pressure port (Fig. 30).
Mow at Proper Intervals Under most normal conditions you will need to mow approximately every 4–5 days. But remember, grass grows at different rates at different times. This means that in order to maintain the same height-of-cut, which is a good practice, you will need to cut more frequently in early spring; as the grass growth rate slows in mid summer, cut only every 8–10 days.

Adjusting the Service Brakes 2. Check the traction pedal stop adjustment. The distance from the top of the stand to the top of the stop must be 1-1/2 in. (38 mm) (Fig. 68). Loosen the nuts and adjust, as required. 1 Adjust the service brakes when there is more than 1 in. (25 mm) of “free travel” of the brake pedal, or when the brakes do not work effectively. Free travel is the distance the brake pedal moves before braking resistance is felt. 1-1/2 in. (38 mm) 1.
2. Place a drain pan under the hub, remove the plug, and allow the oil to drain. 3. When all of the oil has drained, position the wheel so that the plug hole is at the ten or two o’clock position. 4. Place a drain pan under the brake housing on the other side of the wheel (Fig. 71). 5. Remove the plug from the bottom of the housing and allow the oil to drain. 6. When all of the oil has drained, install the plug in the housing. 7. Add approximately 16 oz. (0.5 l) of high quality SAE 85W-140 wt.
Checking the Rear Wheel Toe-In After every 800 operating hours or annually, check the rear wheel toe-in. 1. Measure the center-to-center distance (at axle height) at the front and rear of the steering tires. The front measurement must be 1/4 in. (6 mm) less than the rear measurement. 2. To adjust, loosen the clamps at both ends of the tie rods. 1 3. Rotate the tie rod end to move the front of the tire inward or outward. 4. Tighten the tie rod clamps when the adjustment is correct.
Warning Battery terminals or metal tools could short against metal components causing sparks. Sparks can cause the battery gasses to explode, resulting in personal injury. • When removing or installing the battery, do not allow the battery terminals to touch any metal parts of the machine. • Do not allow metal tools to short between the battery terminals and metal parts of the machine. 1 Warning Figure 75 Incorrect battery cable routing could damage the machine and cables causing sparks.
Fuses 4. Grasp the front of the cutting unit and lift it to an upright position. There are 5 fuses in the electrical system. They are located below the operators control panel (Fig. 76 and 77). 5. Hold the cutting unit upright, fit the cable end over the pin on the cutting unit lift arm and secure it with the hairpin cotter (Fig. 78). 2 1 1 Figure 78 1. Cable Figure 76 2. Pin 1.
Tensioning the Cutting Unit Drive Belts 2 Check the condition and tension of the cutting unit drive belts initially after 8 hours of operation and every 50 operating hours thereafter. The proper belt tension will be attained when a force of 45 lb. on a used belt (90 lb. on a new belt) is applied to the idler pulley (Fig. 80) when sliding it into the belt. 1 Figure 81 1. Height-of-cut chain 2. u-bolt Adjusting the Side Cutting Units 1 1.
Servicing the Castor Arm Bushings 2 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. 1 1. Raise the cutting unit so that the wheels are off of the floor. Block the cutting unit so that it cannot accidentally fall. 3 2.
Checking for a Bent Blade 3. Install the blade, anti-scalp cup, and blade bolt. Tighten the blade bolt to 85–110 ft.-lb. (115–149 N⋅m). 1. Position the machine on a level surface. Raise the cutting unit, engage the parking brake, put the traction pedal in neutral, put the PTO lever in the Off position, stop the engine, and remove the ignition key. Block the cutting unit to prevent it from accidentally falling.
FLAT PART OF BLADE A Correcting Cutting Unit Mismatch SAIL If there is mismatch between the blades, on a single cutting unit, 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. SAIL B 1. Using a 3 foot (1 meter) long carpenters level, find a level surface on the shop floor. WEAR 2. Raise the height-of-cut to the highest position; refer to Adjusting the Height-Of-Cut, page 17.
Replacing the Drive Belt The blade drive belt, tensioned by the stationary 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. Remove the belt covers from the top of the cutting unit and set the covers aside. 2.
