Towing Traction Unit
IMPORTANT: If towing limits are exceeded,  severe
damage to the piston (traction) pump may occur.
If it becomes  necessary to tow  or push the  machine,
move machine in a forward direction at a speed below
2
mph (3.2 kph), and for a very short distance. If the ma-
chine needs to be moved more than 1/4 mile (0.4 km),
machine should be transported on a trailer. The piston
(traction) pump is equipped with two (2) bypass valves
that must be opened for towing or pushing (Fig. 2).
