Well made step, much more affordable than other brands. The green is not JD green however, so if you’re particular like me you’ll want to paint it to match. Not a big deal. Nice having a step to cut the distance to the floorboards on my tractor.

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.

This step fits my John Deere tractor perfectly. It is designed so you don’t have to step on the mower deck to get on the tractor. Easy to install and easy to use.
