The warning system in this manual identifies
potential hazards and has special safety messages that
help you and others avoid personal injury, even death.
DANGER, WARNING and CAUTION are signal
words used to identify the level of hazard. However,
regardless of the hazard, be extremely careful.
DANGER signals an extreme hazard that will cause
serious injury or death if the recommended
precautions are not followed.
WARNING signals a hazard that may cause serious
injury or death if the recommended precautions are
not followed.
CAUTION signals a hazard that may cause minor or
moderate injury if the recommended precautions are
not followed.
Two other words are also used to highlight
information. “Important” calls attention to special
mechanical information and “Note” emphasizes
general information worthy of special attention.
The left and right side of the machine is determined
by sitting on the seat in the normal operator’s
position.

Installing the Carrier Frame to
the T raction Unit
1. Fasten the angle brackets to the traction unit
frame with the six (6) 1/2”-13 x 1” (25 mm) hex
head flange bolts and flange locknuts. Position
the bottom locknuts on the outside of the angle
brackets. Torque the fasteners to 60–80 ft.-lbs

brackets on traction units with hydrostatic
drive, use the 1/2”-13 x 1-1/4” hex head flange
bolts supplied with the traction unit.
2. Attach the carrier frame to the angle brackets
with the four (4) 3/8”-16 x 1-3/4” (44 mm) hex
head bolts and locknuts. Note that the locknuts
must be on the outside of the carrier frame.
Leave the locknuts loose to allow movement
between the carrier frame and angle brackets
(Fig 5).
