Product Description
Manufacturer Part Number: 3421
Use the JD Regular Series Step as a convenient 3-step unit that makes it easier to get in and out of your John Deere® 10-50 Row Crop or Utility Series tractor. An easy to install solution for added safety.
Please Note: Handrails, Adapter Brackets, Extend-A-Step and Additional Fourth Step are sold separately.
For John Deere® 10-20 Row Crop Series Tractors, you need to order the 10-20 Row Crop Series Adapter Bracket (PN: 3401). The 10-20 Row Crop Series Adapter Bracket will work with John Deere® 4520 & 4620 Tractors with modification (the bushing needs to be cut off and the clip will need to be lengthened to fit).
Do not use for 10-20 Series Tractors With Cabs. This step will not fit on 30, 40, 50, 55 series open station tractors (use JD Open Station Step instead).

Heavy gage easy install ,before you start make sure you have a torque wrench 250ft lbs or more. This unit bolts to the existing 3 24mm bolts that hold up the loader arm.They must be torque to 236 ft lbs. No instructions come with the step.
