Very strong hydro on B100 automatic. Long story short, I fell off tractor, it ran against wall and keep working for several seconds before I was able shut it off. Now major hydro leak. Feedback on transmission prognosis and repairability please. Btw, I suffered skinned knee and jammed shoulder. Lol

I have a few few Kohler K Series 4,-12,16HP overhauls coming up. I feel sure they will need to be bored and maybe crank ground. I have the Kohler service manual and have looked at some overhaul threads on here. So my question are:
1. Do you replace the plastic governor gear during a Major Overhaul
2. Do you replace cam shaft bushings?

I have a leak on the elbow that screws into the front of the lift valve. Does anyone know how that is sealed? I looked at parts tree at it doesn't show an o-ring or seal? The elbow is Toro part number 108365. Part #1 on the diagram. Thanks for the help.

Hello all,
I have inherited a 74 B100 with 10hp K241S 46636d when my father passed away. I remembered this tractor new, so when asked, I wanted it. It runs and mows, however, the engine slows and speeds up randomly.
I left it running and lifted the hood. 1st thing I noticed was a loose plug wire, fiddled with it and she spurred up to max rpm. But that only worked randomly as well.(will replace wire soon). 2nd and possibly most importantly I noticed a MASSIVE amount of air/exhaust coming out of the "FIN" area (see pic) Forgive me but, is this normal? I mean it feels like a high powered fan. Any other thoughts on Idle speed random variations would be much appreciated.
