vehicle.

to keep the platform from scraping the
ground when the ATB starts up a grade.

front of the chassis, knob out and turn to lock.
A
DANGER
Death or Serious Injury may occur from a
“runaway” ATB 42/50.
7. Disconnecting the disconnect plates will
allow the ATB 42/50 drive wheels to turn
freely. Before proceeding, be certain the tow
bar is installed and connected to a towing
vehicle that can safely control both itself and
the ATB 42/50.
A
CAUTION
Be certain the tow vehicle brakes are set.
8. Remove the two bolts (1) that hold each drive
wheel disconnect plate (2).
9. Turn each disconnect plate (2) over so that
the nipple (3) points inward, then retighten
the bolts (1).
10. At the end of the tow, before you disconnect
the ATB 42/50 from the towing vehicle, turn
the disconnect plates back over so the
nipples are out. This will prevent the ATB
42/50 from rolling when you disconnect it
from the tow vehicle.
11. Reverse the above procedure at the end of
the tow.

4-Wheel Functions
u
4-Wheel Drive
4-wheel drive improves traction on all surfaces.
There are two ways to tell if the ATB has 4-wheel
drive.
1. Look for the “4x4” decal shown on the front
of the turntable.
2. Look at the wheels. If the hubs of all four wheels
look like this, the ATB has 4-wheel drive.
NOTE
The ATB shown on the front cover of this
manual is a 2-wheel drive machine.
Note that the hub on the front wheel is different.
u
4-Wheel Steer
For a complete discussion of 4-wheel steer see
the “4-Wheel Steer” of the “Operation” chapter 8.
u
4-Wheel Steer With Crab Steer
For the ATB to have crab steer it must first have
4-wheel steer.
For a complete discussion of crab steering see
the “4-Wheel Steer with Crab Steer” section of
the “Operation” chapter 8.
