John Deere tipped this new 8RT series track tractor on end at the German show Agritechnica to give show-goers a good look at its unique undercarriage. Each 8RT tractor is equipped with John Deere's AirCushion suspension system to improve operator comfort and vehicle traction. Customers can select any track spacing between 72 and 160 in. wide by using a field-installed kit to make adjustments without de-tensioning the tracks.
