Specifications
On standard loaders with operator’s station, the hydraulic pilot joystick controls and rocker swing pedal are ergonomically designed for ease of operation and maximum loader control required for the high cycle millyard applications.
The operator station is designed with comfort in mind. The spacious cabs feature a large, fully adjustable suspension seat with lumbar support. Fold-up armrests are fully adjustable to allow adjustment of the joystick controls to match the operator for ease of operation, increased performance.
Excellent visibility of the work area is provided through large tinted cab windows. Overhead visibility is maximized through the large, tinted Lexan skylight. Operator protection is afforded through the front guard. This swing-out guard is designed for quick and simple access to allow cleaning of the front window. »Learn More
Mounting System
The Resilient Pad Mounting System includes a set of special rubber isolators on each mounting fastener that absorbs stress in two directions. An additional hydraulic accumulator is built into the main boom cylinder circuit to further absorb peak-load shocks. »Learn More
