Specialist Off-Road Vehicle Feature - June 1999

Hiller Tdi Tracked All Terrain Vehicle

Manufactured by the Swedish firm of Pist & Terrangteknik AB the Hiller TDi is the newest in a long line of tracked machinery manufactured by this long established firm. Readers may recall the GARRON manufactured by the same company, currently in extensive use in the Highlands of Scotland for mountain rescue and recovery work and power cable and pipeline maintenance operations.

The HILLER has air-suspension on three axles, a modern comfortable cab with suspension seats and heater, and offers excellent all-round visibility and ease of driving position and controls for the operator. It's design is very much state of the art and the 100E (Electronic) variant has an LCD management system for hydraulics, engine, safety alarms and fault search and plug-in computor diagnostic. The heart of the machine is a VW 1.9 litre turbo diesel engine driving through a hydrostatic transmission system, and offering power-take-off applications via a triple hydrostatic pump at 25-65 hp. Tracks are available from 500mm U-profile grouser bars in hi-grade steel to 800mm width in either alloy "L" or "A" profiles.

Fuel economy and durability and exhaust emission levels meet the EURO 2 standards, and hydrostatic gearing gives maximum torque of 4000kg at speeds of up to 20km/h.

Common applications are for Snow-grooming work where the machine is fitted with a 2.5m, 8 way blade at the front and a rear tiller and cross country track setter. Load carrying is 1000KG with a tipping rear body, and optional fitment of a Hiab crane, or pole/log handlers and/or excavator with 2.2m depth. Anywhere were access conditions require the versatility of a low-ground pressure tracked machine the HILLER TDi excells.
