Foam Filled Tires
Foam filled tires eliminate the possibility of air
leaks or blow outs which might cause a tipover.
Inspect them at the start of each work shift
according to the procedures in the “Daily
Inspection and Maintenance” chapter 7.
The foam filled tire shown here is not acceptable
for service.
❑
Large Tires
The large bar lug tires are designed for off
pavement use.
Their additional size provides a little more ground
clearance than regular bar lug tires and the bar
lugs give better traction off pavement.

Tow Kit
Improper towing can cause an ATB 42/50 to
break away from the towing vehicle.
A “runaway” ATB 42/50 can cause Death or
Serious Injury.
Do not tow an ATB 42/50 faster than 10 mph
(16 km/h). An ATB 42/50 can behave
erratically above 10 mph (16 km/ h).
When you tow the ATB 42/50 around a corner
or a curve do not turn so sharply that either of
the yokes are fully turned. If the yokes are fully
turned the steering mechanism might be
damaged or the tow vehicle and ATB 42/50
might jackknife.
Check with the tow vehicle manufacturer or
manufacturer’s literature, to be sure the towing
vehicle can safely tow and stop a 13,600 pound
(6,170 kg) ATB 42 or a 15,280 pound (6,930 kg)
ATB 50 on the steepest grade and type of surface
you will encounter. Remember, the ATB 42/50
does not have brakes when it is towed.

Towing Procedures
1. Remove the tow bar and tie rod weldment
from the storage cradles and lay them near
the front of the chassis.
2. Attach the tow bar to the towing lug with the
tow pin and snap pin.
3. Attach the tie rod weldment to the tow bar
and the right hand steering yoke.
4. Attach the ring end of the tow bar to the tow
vehicle.
5. Raise the platform approximately 3 feet (1 m)
to keep the platform from scraping the
ground when the ATB starts up a grade.
6. Pull the Steering Float Valve, located on the
front of the chassis, knob out and turn to lock.
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.
