Hustler Turf 4300 - Manual (Page 19)

728444 Rev. 11/02 4-1
A large variety of attachments are specifically designed
for your Hustler tractor to handle most ground maintenance
chores. These mount directly on the tractor in various ways,
and each is provided with individual Assembly Instructions,
Parts Manual, and Owner’s Manual which includes
operation and maintenance information.
The following describes standard tractor equipment for
accepting and powering these attachments (Fig. 4-1).
Front tool bar
This is the point of connection between the tractor and
mower decks or other front mounted attachments (dozer
blades, snow thrower, utility scoop, etc.). The tractor
hydraulic system raises and lowers the tool bar assembly
through a series of lifting cables.
These cables can be adjusted to keep attachments level
when in the raised position. If adjustment is necessary,
loosen the lock nut, remove the clevis pin to free the
threaded cable yoke from tool bar bracket. Turn yoke on
threaded cable end to lengthen or shorten effective length as
needed.
Flotation springs
Flotation springs connected between the tractor and front
mounted attachments act as shock absorbers, allowing the
attachment to float when moving over uneven ground.
Proper flotation provides good balance and weight
distribution with tractor for best drive wheel traction. The
tractor comes standard equipped with three of these springs
which must be connected as specified in instructions
supplied with the attachment being mounted.
PTO shaft
This telescoping shaft assembly delivers live engine
power to front mounted attachments through the electric
clutch. When not connected to an attachment, the shaft
must be secured to the hanger located under the tractor
footrest.
WARNING: Never turn the PTO switch ON
unless the PTO shaft is securely connected to a
power driven attachment.
The PTO electric clutch switch bracket (on operator’s
platform) has provisions for inserting a lock out pin so
switch may not be unintentionally switched on when PTO
shaft is not connected to attachment.
This shaft assembly has three grease fittings for periodic
servicing when in use. Refer to the maintenance schedule
for frequency.
Auxiliary hydraulics
The tractor’s hydraulic system includes a control valve,
hoses and quick-connect couplers for supplying hydraulics
to attachment cylinders. When not in use, the coupler dust
covers must be in place to prevent contamination. Always
replace them immediately if damaged or lost.
Once connected, the operator has control of the
attachments’ hydraulic cylinder by means of the control
lever on operator’s deck. If stroking the lever produces the
wrong cylinder movement (up-down, right-left, etc.),
reverse the attachment hoses at the quick-connect couplers.
WARNING: Never attempt to connect or
disconnect the couplers with pump clutch
engaged and system oil under pressure.
