QUADTRAC® tractors have positive drive tracks, rather than the friction drive type that is used by the competitive two-track system. This means the drive wheel has driving cogs that engage with a molded lug on the track assembly, and as the drive wheel rotates, the track assembly is propelled. This assures a positive drive, improved braking and overall control of the tractor.
The unique design of this tractor also allows both the front and rear axle to be equipped with a differential lock for improved traction. Two track systems cannot offer this feature because their steering control is tied to the two tracks.
By incorporating internal wet brakes in the axle assembly, the braking system has been improved over conventional 4WD tractors that locate their braking system on the driveline.
