Operator Station
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.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.Enclosed Components
Weatherproof electric service panels include starters, controls, transformers, circuit breakers and fuse blocks.Motor Options
Electric motors range in horsepower from 75 to 100 hp and are totally enclosed and rated for severe duty. Power supply wiring packages provide for 440V/60Hz US or 575V/60Hz Canadian service.Boom Length Options
