Tuthill Drive Systems showed its new EZ Trac hydraulic drive system, which it said provides front-wheel drive for on-road trucks that need to go off-road or travel in bad weather.
EZ Trac installs on the front steering axle and is activated by a cab-mounted switch when a driver needs additional traction and mobility, according to Tuthill. The company pointed out that the system uses “simple hydraulic technology” and weighs hundreds of pounds less and is easier to service than conventional front wheel drive systems.
Once the truck is back on the pavement or weather conditions improve, the company said, EZ Trac can be easily switched off for normal freewheeling operation. Tuthill also noted the system can be set to automatically disengage above 20 mph and engage when rear wheels lose traction.
