Inspecting The Tires; Checking The Front-Wheel Alignment - Toro 07385 Workman HDX-D Operator's Manual

Inspecting the Tires

Service Interval: Every 100 hours
The air pressure in the front tires should be 220 kPa (32 psi)
and the rear tires should be 124 kPa (18 psi).
Operating accidents, such as hitting curbs, can damage a tire
or rim and also disrupt wheel alignment, so inspect the tire
condition after an accident.
Important: Check the tire pressure frequently to ensure
proper inflation. If the tires are not inflated to the correct
pressure, the tires will wear prematurely and may cause
4-wheel drive to bind.
Figure 54 is an example of tire wear caused by under inflation.

Figure 55 is an example of tire wear caused by over inflation.

Checking the Front-Wheel
Alignment
Service Interval: Every 400 hours/Yearly (whichever comes
first)
1. Make sure that the tires are facing straight ahead.
2. Measure the center-to-center distance (at axle height) at
the front and rear of the steering tires
Note: The measurement must be within 0 ± 3 mm (0
± 0.12 inch) at the front of the tire then at the rear of
the tire. Rotate the tire 90° and check the measurement.

Important: Check the measurements at consistent
locations on the tire. The machine should be on a
flat surface with the tires facing straight ahead.

front to rear of the tire
3. Adjust the center-to-center distance as follows:
A. Loosen the jam nut at the center of the tie rod
(Figure
1. Tie rods
B. Rotate the tie rod to move the front of the tire
inward or outward to achieve the center to center
distances from front to back.
C. Tighten the tie rod jam nut when the adjustment
is correct.
D. Check to ensure that the tires turn an equal
amount to the right and to the left.
Note: If the tires do not turn equally, refer to the
Service Manual for the adjustment procedure.
