Towing A Trailer With The Machine; Using The Hydraulic Control - Toro 07385 Workman HDX-D Operator's Manual

Towing a Trailer with the
Machine
The machine is capable of pulling trailers and attachments of
greater weight than the machine itself.
Several types of tow hitches are available for the machine,
depending on your application. Contact your Authorized
Toro Distributor for details.
When equipped with a tow hitch bolted onto the rear axle
tube, your machine can tow trailers or attachments with
a Gross Trailer Weight (GTW) up to 1,587 kg (3,500 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 (1,500 lb) GTW is towed behind a 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 fifth-wheel attachments, like a fairway aerator,
always install the wheel 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 runs. The power can be
used through the quick couplers at the rear of the machine.
CAUTION
Hydraulic fluid escaping under pressure can have
sufficient force to penetrate skin and do serious
damage.
Use care when connecting or disconnecting
hydraulic quick couplers. Shut off the engine,
apply the parking brake, lower the attachment, and
place the remote hydraulic valve in the float detent
position to relieve the hydraulic pressure before
connecting or disconnecting the quick couplers.
Important: If multiple machines use the same
attachment, cross contamination of the transmission
fluid may occur. Change the transmission fluid more
frequently.
Using the Hydraulic-Bed-Lift Lever to
Control Hydraulic Attachments
•
O Position
FF
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 is held by the
check valves in both directions.
•
R (Quick Coupler "A") Position
AISE
This is the position which lifts the bed, rear-hitch
attachment, or applies pressure to quick coupler A. This
also allows hydraulic fluid to return 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, O
1. Quick coupler A position
•
L (Quick Coupler "B") Position
OWER
This position lowers the bed, rear-hitch attachment, or
applies pressure to quick coupler B. This also allows
hydraulic fluid to return 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 hydraulic-fluid 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 hydraulic-fluid flow to go over a relief valve,
which can damage the hydraulic system.
•
O Position
N
This position is similar to Lower (quick coupler B
position). It also directs hydraulic fluid to quick coupler
B except that the lever is held in this position by a
detent lever in the control panel. This allows hydraulic
fluid to flow continuously to equipment that uses a
31
position.
