Hustler Turf 4500 Accessories, PTO shaft, Front tool bar, Flotation springs, Auxiliary hydraulics

ACCESSORIES

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).

Flotation

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.

Figure 4-1

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.

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

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.
