For over a quarter century, Gyro-Trac has been manufacturing the most productive mulching machines that produce more mulch for less horsepower, less fuel, less weight and, pound for pound, for less total cost per pile of mulch than any other brand. Under eleven patents and several patents pending, Gyro-Trac produces tracked mulching machines from 140 to 350 horsepower with aggressive captive track and steel track undercarriage options; high-flow and low-flow cutter-heads for skid steers and excavators; a light weight, high productivity boom mounted cutter-head for tractors and track hoes; and the Bio-energy Baling System (BBS-XP) that is fully integrated with the 350 HP GT-35 tracked mulching machine.
