Towing Traction Unit - Toro Reelmaster 7000-D Service Manual

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, at a speed below
3 mph (4.8 kph) and for a distance less than 1/4 mile
(0.4 km). The piston (traction) pump is equipped with a
bypass valve that needs to be turned 90
(Fig. 1). Do not turn bypass valve when engine is run-
ning.
IMPORTANT: If the machine must be pushed or
towed in the reverse direction, the bypass valve
o
needs to be turned 90 , and a check valve in the rear
traction manifold must be bypassed. Do not exceed
3 mph (4.8 kph) or a distance of ¼ mile (0.4 km) when
pushing or towing the machine in reverse.
The following Toro parts are needed to bypass the check
valve:
59−7410 diagnostic fitting
354−79 diagnostic fitting cap
95−8843 hydraulic hose
95−0985 coupler fitting (2)
340−77 hydraulic fitting (2)
NOTE: The #6 zero leak plug on the rear traction mani-
fold has a tapered sealing surface on the plug head.
Lightly rap the plug head using a punch and hammer be-
fore using an allen wrench to remove the plug. The im-
pact will allow plug removal with less chance of damage
to the socket head of the plug.
1. To bypass the check valve, install a diagnostic fitting
in the unmarked port located between ports M8 and P2
on the rear traction manifold (Fig. 2).
2. Connect a hydraulic hose between the diagnostic fit-
ting installed in the rear traction manifold and the re-
verse traction pressure test port (Fig. 3).
