fabo farmers, what kind of tractor?

4. Read, and heed, the safety info in your owners manual. There is no room for mistakes, especially around the PTO.

Big X2 on this. I think the MF135 you have has the PTO shield removed. Hard to tell from the picture, but it looks like a PTO stub between the rear wheels. This was commonplace because it is a PITA to reach around the shield to disengage the PTO shaft. This tractor will have a live PTO, meaning it turns at all times. Many accidents have happened when the operator dismounts to the back of the running tractor and loose clothing catches in the PTO shaft, (It's turning 540 rpm with 30 hp behind it. You won't stop it manually). Nothing like the loss of life and limb to mess up your stress free retirement.
