Extend the life of your tractor tires with Lankota's Stalk Roller system for John Deere 2015 & newer 9R Series tractors. Tire configuration: Triples 480mm & 520mm, Duals 620mm & 650mm or Duals 710MM & 800mm. The 74-inch wide roller will greatly lessen tire damage done by any crop stalk. Large pillow block style bearings keep the 14-inch diameter roller turning, crushing sharp and abrasive crop residue in front of the tractor tires. The system folds and unfolds hydraulically from the cab. If available, use a separate hyd. remote for these functions or tie them directly in with your implement lift.
