I decided to go ahead with a diesel repower for the Bush Hog. I went with a Kubota d1105-e from an old Toro Reel Master, from what I find on the internet it’s about a 25hp engine so I should never run out of power. The rear end that was in the tractor is shot; it always acted like it wanted to lockup under load. So I'm going with a cast iron unit from a Cub Cadet 149 with the ported pump so I can keep the hydro lift. I still need to reverse it, and so while I got it apart it will get the fine spline axles, maybe later after some testing I might look for the guts from a super to go in it, but for now I think it should be ok. Still got a lot to get done but it is looking like everything is going to fit nicely. I was going to use the tranny cooler in the radiator but I found out from one of the cub guys that the lift circuit on the pump is also the charge pressure so it runs like 800 psi, so I guess I’ll need to come up with an oil cooler that can handle the pressure or come up with a way to circulate the fluid at a lower pressure.
