Hydraulic Control - Toro 07360 Operator's Manual

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 rear axle
tube, your Workman can tow trailers or attachments
with a Gross Trailer Weight (GTW) up to 1500 lbs.
Always load a trailer with 60% of the cargo weight in
the front of the trailer. This places approximately 10%
(200 lbs. max.) of the Gross Trailer Weight (GTW) on
the tow hitch of the vehicle.
When towing either standard tongue or 5th wheel
trailers having a Gross Trailer Weight (GTW) in excess
of 1500 lbs., use either a chassis mounted draw bar hitch
(rated for 3500 lb. GTW) or 5th wheel kit with brakes.
Trailer brakes are required whenever a trailer over 1500
lbs. 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 "live" 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.
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.
1. Quick coupler "A" position
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.
