After replacing the rest of power steering hoses on my 4020PS, I installed the sleeve hitch and mounted the tiller. It’s the end of May and still too wet to till the garden. With everything connected and the tiller raised, I engaged the rear PTO to test the tiller; the engine nearly quit. I tried again with same results so pushed it back inside to think about it. After letting it sit overnight, I checked whether it was still stuck or blocked (it was) so I tried reverse. Kapow! Something popped and oil shot straight back (7’ 4”). The tiller’s hydraulic motor housing cracked horizontally across the back side below the hose fittings. Model: H70, serial no: 0031154, part no: C24695. Repair or replace?
