Manitou has released a lineup of construction machinery based on the experience from the Gehl and Mustang compact track loader undercarriage designs. The Manitou 1650RT is the most versatile option in the lineup. We do not currently offer undercarriage parts for the Manitou 1650RT but you may ask, what size rubber track fits on the Manitou 1650RT? The 1650RT uses the standard width 320 x 86 x 49 and we offer it in several tread pattern options. The optional sixteen-inch wide 400 x 86 x 49 is also available for this model.
