Canopy:

Walk-through canopy allows access to operator's station from ei-
ther side. Canopy frame is a tip-over protective structure (TOPS)
with steel roof for operator protection. Both right and left control
stands can be locked to prevent unwanted actuation of digging
functions. Adjustable vinyl seat, fore and aft.

Controls:

All hydraulic functions are actuated by low-effort direct acting con-
trols. Two levers control swing, boom, arm and bucket functions.
Right and left propel levers control forward, reverse and track coun-
terrotation. A floor-mounted pedal controls boom swing. A lever to
the right of the operator controls raising and lowering the blade.

Boom and Arm:

The boom can be pivoted 50 degrees left and right. The boom and
arm are welded, low-stress, full box-section designs.
Armlength 3ft.11in.(1.20m)

Servicing and Vandal Protection:

Handrails are provided for easy servicing. Tilt-up engine cover pro-
vides unrestricted access. Engine cover and fuel cap have built-in
