Ultra Narrow Rubber-Tracked Tractor
![]() |
"With narrow 8-in. tracks and 30 in. ground clearance, it was developed for spraying, fertilizing or cultivating specialty crops such as onions. But one grower has already asked us to build him a hi-boy version with 6 ft. of ground clearance so he can use it to top dress corn," says Dave Grossen of GK Machine, Donald, Ore.
The TR2 Tracker is Deere-powered, either by an 80 hp or 110 hp turbocharged diesel. The engine is coupled to a Sundstrand hydrostatic transmission that uses twin 35 gpm pumps.
The track system features on-the-go hydraulic width adjustment. Using telescoping axles, width can be adjusted from 60 to 80 in. without stopping. Tension is maintained with a hydraulic cylinder that applies pressure to 13-in. dia. idler wheels.
Tracks are available in 8 and 11.7-in. widths, turning on six 11-in. dia. roller wheels. With a full 3,000-lb. payload, ground pressure ranges from 4 to 6 psi de-pending on which tracks are being used. Top speed is 9 and 15 mph, respectively.
Options include cab with pressurized charcoal filter system, 80 hp pto, a Cat. # II 3 pt. hitch, 50 or 60-ft. suspended spray booms, Hypro spray pump, and a 250-gal. stainless steel or poly tank. The spray system mounts on a modular platform that attaches and detaches from the rear in seconds with just two bolts.
Starts at $50,000.
