Extend the life of your tractor tires with Lankota's Stalk Roller system for John Deere 9RX Series tractors. Tire configuration: Tracks 18" - 36". The 52-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.
