3.8 QUICK ATTACH ASSEMBLY
This machine is equipped with a quick attach assembly
system for easy attachment changes.
3.8.1 Disconnecting from an Attachment
1. Park the machine on a hard, level surface.
2. Place the transmission control lever in the (N)
NEUTRAL position and engage the parking brake
switch

ground the attachment and tilt the carriage
backward. Shut the engine OFF.
4. Exit the machine using both hand holds.
Note: If removing a standard carriage with forks, spread
the forks apart on the carriage shaft. This will help give
the carriage better support to stand alone.

the lock pin (3) at the bottom of the quick attach.

Position the machine directly behind the attachment
to be mounted.

drive the machine forward until the attachment pivot
pins are below and between the two hooks on the
attachment.
4. Raise the boom until the attachment pivot pins have
seated fully in the hooks on the attachment.
5. Tilt the attachment up slightly. The quick attach link
should be tight up against the rear of the attachment,
and the holes in the link and the attachment should
be aligned.
