I have the step with the grab handle on my 1971 4020 with a WL 42 loader. It does touch the loader but never an issue. The factory step is way to narrow for my big old feet. Highly recommend it. Seems I bought mine at a farm show.
Do you know which one you have? Could you get a picture of how it's mounted and the clearance to the loader? I haven't been over to look at his tractor but apparently the rear loader bracket position could cause an issue. A WL42 is a fairly short loader compared to a WL40. |
