Adjustable Tow Head

Figure 2 - Adjustable Tow Head

Figure 3 - Tow Head Adjustment

The preferred towing angle of any chipper is with the chassis level to the ground.

The TW 280PHB chipper has the ability to adjust the tow head height to correspond with
the vehicle's towing point. The adjustable head can be moved between 432 mm and 1005
mm from the ground, giving an overall adjustment range of 573 mm.

The tow head must only be adjusted when the chipper is NOT hitched to a vehicle and
is in a stable position.

The adjustable tow head functions in the same way as a fixed standard tow head. The front
section of the head is retained in position using two locking rings.

To adjust the height of the towing head:

1.

Turn the locking handle located on the side of the head, in an anticlockwise direction to
allow the locking ring to disengage from its opposing ring (Figure 3, Item 1).

2.

Move the tow head to the desired height.

3.

Turn the locking handle clockwise until the tow head is tightly held in the required

position.

When the tow head is set to the correct height, the chipper can be hitched to the towing
vehicle in the normal manner (Section 4.2 "

Hitching to the Towing Vehicle" on page 21).
