Features

PLATFORM

Operator’s platform features large adjustable operator’s seat with padded armrests. Joystick control valves designed to provide smooth and consistent loader control. Access ladders and hand grabs are positioned for maintaining “three-point” contact. Swing system provides quick, smooth and controlled response to joystick commands.

HYDRAULIC

The 3200 PSI hydraulic system maximizes lift capacity and improves controllability of the loader during multi-function operations. Redesigned continuous rotation assembly improves hose routings and ease of maintenance. A 5-circuit hydraulic swivel is standard.

ELECTRICAL

An 8-circuit electrical collector standard for providing electrical power and setting stabilizers. Work light packages for stick boom and operator’s platform are optional. Optional 25’ (7.62 m) Teleboom features thumb-switch proportional control.

STRUCTURAL

A-Frame pedestal is formed of high strength steel to maximize strength and minimize weight

BOOM STRUCTURE

Castings at main boom base, midpoint and stick end minimize weight and maximize strength.
