Predator engine swap to replace Kolher

Recommended Posts

The Harbor Freight 22hp V twin engine is a good engine swap for the Kohler twin. The swap is not for the collector but is good for a working tractor. The engine is powerful and fits well into a large frame tractor. My father made adapters from aluminum from Speedy Metals to swap this motor in his tractor. The motor mounts raise the engine, as it has a lower crank center-line then the opposed twin Kohler. The drive shaft to motor needs an adapter also to complete the drive line. These adapter plans are available for purchase please email me at: tractorplans@gmail.com

Thanks Ken in Mi

Welcome to the 7122 club!!! I'm very curious about your headlights as well. I ended up tucking the muffler in close enough to run the stock headlights since I had to make a custom one anyways.

We did not put the head lights back in but, it looks like you could just space them forward. Thanks for all the nice comments, this is a great club.
