DESIGN AND FUNCTION

Design and Function

General

The Husqvarna ZTH is a compact, ride-on mower specially designed for mowing large areas of grass. It is operated via two motion control levers and has hydrostatic drive to the rear wheels. Each rear wheel is driven by an independent hydrostatic drive system comprising a hydraulic pump and a hydraulic motor. The hydraulic pumps are driven by a belt from the engine’s crankshaft.

The mower is steered by the independent adjustment of the speed and direction of each rear wheel. The front wheels are free to turn in whichever direction is most suitable.

The mower deck is mounted underneath the mower and is supplied with a side discharge chute as standard. The range of accessories includes a BioClip kit of guide plates and blades for mounting beneath the mower deck casing.
