Manitou has released a lineup of construction machinery based on the experience from the Gehl and Mustang compact track loader undercarriage designs. The Manitou 1050RT is the smallest option in the lineup. We do not currently offer undercarriage parts for the Manitou 1050RT but you may ask, what size rubber track fits on the Manitou 1050RT? The 1050RT uses the ten-inch wide 250 x 72 x 52 and we offer it in several tread pattern options.
