Great product fixed my old cutter
Great product fast shipping. On older John Deer models (403) and those like it. There is a ring where the old gear box mounted that will need to be cut out.

Still worth the money
Worked well but after 25 hours of us the flange that holds the gears in broke. Probably because a piece of rock hit it.
