Towing Traction Unit
IMPORTANT: If towing limits are exceeded, severe
damage to the piston pump may occur.
If it becomes necessary to tow (or push) the machine,
tow (or push) in a forward direction only, at a speed
below3 mph(4.8 kph)andforadistanceless than1/4
mile (0.4 km). The piston (traction) pump is equipped
witha bypass valve thatneeds to be turned 90
o
fortow-
ing. Do not turn bypass valve when engine is running.
See TractionUnit Operator’s Manual for additional tow-
ing procedures.
IMPORTANT: If the machine must be pushed or
towed in a reverse direction, the check valve in the
4WD/2WD control manifold must be bypassed. To
bypass this check valve, connect a hydraulic hose
between the reverse traction pressure test port and
the 4WD/2WD control manifold t est port (G). Toro
part numbers 95--8843 (hydraulic hose), 95--0985
(coupler fitting) (2 required) and 340--77 (hydraulic
fitting) (2 required) are needed for this connection.
