Towing The Machine; Towing A Trailer With The Machine; Using The Hydraulic Control - Toro 07390 Workman HDX-Auto Operator's Manual

Towing the Machine

In case of an emergency, the machine can be towed for a
short distance. However, Toro does not recommend this as
a standard procedure.
WARNING
Towing at excessive speeds could cause machine
to lose steering control. Never tow machine faster
than 8 kph (5 mph).
Towing the machine is a 2-person job. Affix a tow line to
holes in the front frame member. Move the shifter to Neutral
and release the parking brake. If the machine must be moved
a considerable distance, transport it on a truck or trailer.
Note: The power steering will not function, making it
difficult to steer.
Towing a Trailer with the
Machine
This machine is capable of pulling trailers and attachments of
greater weight than the machine itself.
Several types of tow hitches are available for this machine,
depending on your application. Contact your Authorized
Distributor for details.
When equipped with a tow hitch bolted onto the rear axle,
your machine can tow trailers or attachments with a gross
trailer weight (GTW) up to 1587 kg (3500 lb). Always load a
trailer with 60% of the cargo weight in the front of the trailer.
This places approximately 10% (272 kg (600 lb) max.) of the
gross trailer weight (GTW) on the tow hitch of the machine.
Trailer brakes are required whenever you tow a trailer over
680 kg (1500 lb) GTW is towed behind this machine.
When hauling cargo or towing a trailer (attachment), do not
overload your machine 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 fifth wheel kit)
to prevent the front wheels from lifting off the ground if the
towed attachments movement is suddenly impaired.

Using the Hydraulic Control

The hydraulic control supplies hydraulic power from the
machine pump whenever the engine is running. Use the
quick couplers at the rear of the machine to provide hydraulic
power for rear hitch attachments.
Important: If multiple vehicles use the same
attachment, cross contamination of the hydraulic fluid
may occur. Change the hydraulic fluid more frequently.
Hydraulic Control 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 hydraulic lift lever position lifts the bed cylinders or a
rear hitch attachment by applying Raise hydraulic pressure
through quick coupler A. This also allows the return oil to
flow through quick coupler B, back through the control
valve, and then into the reservoir. This is a momentary
position; when the hydraulic lift lever is released, a spring
returns the lever to the Center Off position.
1. Quick coupler A position
•
Lower (Quick Coupler B position)
This position lowers the bed or a rear hitch attachment by
applying Lower hydraulic pressure through quick coupler
B. This also allows the return oil to flow through quick
coupler A, back through the control valve, and then into
the reservoir. This is a momentary position; when the
hydraulic lift lever is released, a spring returns the control
lever to the Center Off position. Momentarily holding
and then releasing the hydraulic lift lever in this position
will provide flow to the quick coupler B, which provides
Lower hydraulic pressure to the bed cylinders or a rear
hitch attachment. When the hydraulic lift lever is released,
the Lower hydraulic pressure to the bed cylinders or a
rear hitch attachment is hydraulically locked.
Important: If used with a hydraulic cylinder,
holding the hydraulic lift lever in the Lower position
