I thought I'd start a thread on my latest repower project that I did back in the summer. What I wanted to do was to use it as a grass cutter.
I bought a Compete MF12Hydro tractor with mower deck, minus the engine off a fellow GTTalk member for this repower. I also bought a 13hp Honda Clone on sale at Princes Auto, engine came with pull and electric start.
Installed it in the tractor without too much trouble, using the tractors gas tank. Rigged up the exhaust and used a bushing for the pulley on the crankshaft.
I have cut the grass many times with it and it has worked great, lots of power, easy to start and fairly quiet.
However it has some issues.
1 - The tractors fuel tank gets hot, too hot for my liking, if it's a windy day it's OK but if there's no wind on a hot summer day I don't like it. I have tried a couple of different exhaust setups but still too hot. I think the answer is to route the exhaust out as low and direct as possible, the way it is now the cooling air from the engine gets heated up from the exhaust and goes up under the hood heating up everything.
2 - This engine seems to vibrate a lot, I haven't checked the rpms, they seem high,??? need to put a tach on it and check. The screw that limits the governor setting moves, that needs to have some thread locker on it, I noticed this with the other repowers I have done.
3 - The choke control cable works backwards the way I did it.
This is a ongoing project still needs some things done.
Fix the hot fuel tank problem, exhaust.
Put a battery in it, get the starter and lights working.
Tighten up the steering, too sloppy right now.
I also plan to put my MF620 snow blower on it and will see how it does this winter.
Here's a Video of it cutting some grass.
