Drive System: A hydrostatic closed loop circuit with series or parallel drive. It also has a "positraction" feature which is operational when the system is in parallel drive. If one wheel or axle is spinning the greater pressure then drops across that spool of the divider/combiner cartridge shifting it and equalizing the flow. This ensures that both wheels or both axles will have power.

Weight: A42RT has a gross weight of 13,500 lbs. It is designed to be self-loading and it is light enough to legally transport two units on one truck.

Accessibility: Accessibility to the engine is provided with a swing door on each side of the chassis plus a removable top cover. All hydraulic components are in the front of the chassis, which has a removable cover.

Ground Controls: Electrical and hydraulic ground controls are mounted on the left side of the turret (when viewed from the platform). All electrical components are in a NEMA electrical enclosure that is sealed to protect them from the elements. All hydraulic components have a ~ removable cover over them.

Steering : 2-wheel steering is industry competitive with an outside turning radius of 15' (4.6m). The steering is done through a Piggy-Back pump that is mounted to the end of the hydrostatic pump, which supplies pressure and flow to operate steering.

Chassis: Chassis is designed so the optional 4-wheel drive can be installed without any chassis modification.

Rough terrain capability: Gradeability on the 2-wheel drive is 28% (15.50), adequate for most job sites. Optional 4-wheel drive increases gradeability to 32% (17~). The 2-wheel drive unit has the drive and steering in the same axle for improved terrain ability. High speed drive is 3.0 mph (4.8 kmh) and low speed is 1.5 mph (2.4 kmh), creep speed is 0.75 mph (1.2 kmh).

Stowed Height: The stowed height is only 7' 8", which allows the unit to go through an 8' door.
