The LANSRJD8000 is a stalk roller kit for John Deere 20, 30, 8R & 8RT Series tractors. The 52" wide rollers will greatly lessen the tire damage done by any crop stalk. The large pillow block style bearings keep the 14" diameter roller turning, crushing sharp and abrasive crop residue in front of the tractor tires. The system fold and unfolds hydraulically from the cab. If available, use a separate hydraulic remote for these functions, or tie them directly in with your implement lift.
