Toro Workman HDX-D - Inspecting the Tires; Checking the Front Wheel Alignment

Inspecting the T ires
Service Interval : Every 100 hours
Front tires air pressure specication: 220 kPa (32
psi)
Rear tires air pressure specication: 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 ination. If the tires are not
inated to the correct pressure, the tires will wear
prematurely and may cause 4-wheel drive to bind.
Figure 46 is an example of tire wear caused by
under-ination.

Checking the Front Wheel
Alignment
Service Interval : Every 400 hours/Y early (whichever
comes rst)
1. Ensure that the tire pressures are correct before
checking the front wheel alignment; refer to
Checking the T ire Pressure ( page 21 ) .
2. Either have an operator in the operator ’ s seat
or add weight to the driver ’ s seat equal to the
average operator of the vehicle.
The operator or weight must remain on the seat
for the duration of the front wheel alignment
procedure.
3. On a level surface, roll the machine straight back
2 to 3 m (6 to 10 ft) and then straight forward to
the original starting position.
This allows the machine suspension to settle
into the normal operating position.
4. Ensure that the tires are facing straight ahead.
5. Measure the distance between the front tires at
axle height at both the front and rear of the tires
( Figure 48 ).
The front wheel toe-in should be 0 ± 6 mm (0
± 1/4 inch).
Important: Check the measurements at
consistent locations on the tire. The machine
should be on a at surface with the tires
facing straight ahead.

A. Loosen the jam nut at the center of the tie
rod ( Figure 49 ).
