Towing A Trailer With The Vehicle; Hydraulic Control - Toro Workman HD 07369 Operator's Manual

Towing a Trailer with the
Vehicle
The Workman is capable of pulling trailers and
attachments of greater weight than the vehicle itself.
Several types of tow hitches are available for the
Workman, depending on your application. Contact
your Authorized Toro Distributor for details.
When equipped with a tow hitch bolted onto the
rear axle tube, your Workman can tow trailers or
attachments with a Gross Trailer Weight (GTW) up to
3500 lb (1587 kg). Always load a trailer with 60% of
the cargo weight in the front of the trailer. This places
approximately 10% (600 lb (272 kg) max.) of the Gross
Trailer Weight (GTW) on the tow hitch of the vehicle.
Trailer brakes are required whenever you tow a trailer
over 1500 lb (680 kg) GTW is towed behind a Workman
vehicle.
When hauling cargo or towing a trailer (attachment), do
not overload your vehicle or trailer. Overloading can
cause poor performance or damage to the brakes, axle,
engine, transaxle, steering, suspension, body structure,
or tires.
Important: To reduce potential for drive line
damage, use low range.
When towing 5th wheel attachments, like a fairway
aerator, always install the wheely bar (included with the
5th wheel kit) to prevent the front wheels from lifting
off the ground if the towed attachments movement is
suddenly impaired.

Hydraulic Control

The hydraulic control supplies hydraulic power from
the vehicle pump whenever the engine is running. The
power can be used through the quick couplers at the
rear of the vehicle.
Important: If multiple vehicles use the
same attachment, cross contamination of the
transmission fluid may occur. Change the
transmission fluid more frequently
Control Lever Positions
• Off Position
This is the normal position for the control valve
when it is not being used. In this position the work
ports of the control valve are blocked and any load
will be held by the check valves in both directions.
• Raise (Quick Coupler "A" Position)
This is the position which will lift the bed, rear
hitch attachment or apply pressure to quick coupler
A. This also allows return oil from quick coupler
B to flow back into the valve and then out to the
reservoir. This is a momentary position and when
the lever is released it spring returns to the center
off position.
1. Quick coupler A position
• Lower (Quick Coupler B Position)
This position will lower the bed, rear hitch
attachment, or apply pressure to quick coupler B.
This also allows return oil from quick coupler A
to flow back into the valve and then out to the
reservoir. This is a momentary position and when
the lever is released it spring returns to the center off
position. Momentarily holding and then releasing
the control lever in this position will provide flow
to quick coupler B which provides power down on
the rear hitch. When released, it will hold the down
pressure on the hitch.
Important: If used with a hydraulic cylinder,
holding the control lever in the lower position
causes the oil flow to go over a relief valve which
can damage the hydraulic system.
• On Position
This position is similar to Lower (quick coupler
B position). It also directs oil to quick coupler B
except that the lever is held in this position by
a detent lever in the control panel. This allows
oil to flow continuously to equipment that uses a
hydraulic motor. This position must only be used
on attachments with a hydraulic motor attached.
Important: If used with a hydraulic cylinder or
no attachment, the On position causes the oil
flow to go over a relief valve which can damage
