Towing
If it becomes necessary to tow (or push) the machine,
tow (or push) at a speed below 1 mph (1.6 kph), and for
a very short distance. If machine needs to be moved a
considerable distance, machine should be transported
on a trailer. Refer to Traction Unit Operator’s Manual for
Towing Procedures.
IMPORTANT: If towing limits are exceeded, severe
damage to the transmission may occur. Also, if ma-
chine is towed too fast, wheels may lock up. If wheel
lock up occurs, stop towing the machine. Wait for
traction circuit pressure to stabilize before resum-
ing towing at a slower speed.
Relieving Hydraulic System Pressure
Before disconnecting or performing any work on the hy-
draulic system, all pressure in the hydraulic system
must be relieved. Park machine on a level surface, lower
attachment, turn key switch to OFF and allow engine to
stop.
To relieve hydraulic pressure in traction circuit, move
traction pedal to both forward and reverse directions. To
relieve hydraulic pressure in lift circuit, move lift lever to
lower. To relieve hydraulic pressure in Sand Pro 5040
and Infield Pro 5040 steering circuit, rotate steering
wheel in both directions.
Traction Circuit Component Failure
The traction circuit on Sand Pro and Infield Pro ma-
chines is a closed loop system that includes the hydros-
tat and three (3) wheel motors. If a component in the
traction circuit should fail, debris and contamination
from the failed component will circulate throughout the
traction circuit. This contamination can damage other
components in the circuit so it must be removed to pre-
vent additional component failure.
Once the filter has been placed in the circuit, operate the
traction circuit to allow oil flow through the circuit. The fil-
ter will remove contamination from the traction circuit
during circuit operation. The filter can be removed from
the machine after contamination has been removed
from the traction circuit.
IMPORTANT: When operating the traction system with
the high pressure filter installed, make sure that flow is
always directed through the filter before entering a re-
placed component (e.g. do not press the traction pedal
in the reverse direction if the filter is placed for forward
direction flow). If flow is reversed, debris from the filter
will re–enter the traction circuit.
If a component failure occurs in the traction circuit, it is
recommended that the entire traction circuit be disas-
sembled, drained and thoroughly cleaned to ensure that
all contamination is removed from the circuit. If any de-
bris remains in the traction circuit and the machine is op-
erated, the debris can cause additional component
failure.
An alternative method of removing traction circuit con-
tamination would be to temporarily install a high pres-
sure hydraulic oil filter (see Special Tools) into the circuit.
The filter should be used when connecting hydraulic test
gauges in order to test traction circuit components or af-
ter replacing a failed traction circuit component (e.g. hy-
drostat or wheel motor). The filter will ensure that
contaminates are removed from the closed loop and
thus, do not cause additional component damage.
Optional Hydraulic Accessories
Numerous hydraulic accessories are available for Sand
Pro and Infield Pro machines. Make sure to retain Instal-
lation Instructions, Operator’s Manuals and other infor-
mation if your machine is equipped with any optional
hydraulic accessories.
The Hydraulic Schematics section of this chapter in-
cludes the hydraulic schematics for the optional remote
hydraulics kit and front lift kit.
