Several years ago there was a 422 owner that swapped out his 22hp Robin with a 29hp liquid cooled Kawasaki. I remember reading after seven hours on the machine the tran pump went and he just gave up on it. I remember he said it would start right up in zero degree weather and had much more power than the original 22 hp Robin. Anyone remember this thread? Would love to swap out my 22 hp for a 29 hp Kawasaki. What are your thoughts on it?

A friend of mine and I went up to NY and he bought it years ago and it is still running . He made several changes to it and I don't believe he has had problems with it since. He is a very good mechanic and can work on just about anything.

Thanks JJ for the links. It appears there is a lot more room in the tub with the Kawasaki then with the Robin. Why can this engine start in seconds with freezing temperatures. I would love to put the kawasaki in my 422. I am a you tube - monkey see - monkey do- mechanic at best.

ernemats, you have a 422 and you have seen the 429, if your Robin died, would you convert it to the Kawasaki?

I would like to see if one of those 2 cylinder Chinese diesels would fit in the tub of a PT. I wonder how they start in the cold?

As a minimum, I think I would stick in the Robin Fuel Injected 27HP engine (same dimensions), a no-brainer (if you have the extra $$$)

The water cooled upgrade would be a bit more of a challenge, but I think knowing in advance some of the pitfalls associated with shoe-horning it into the tub may make it go smoother.

I would like the extra power, the 22HP is just a bit too light-weight for brush hogging.

No I don't think I would want to go to the modifications needed to convert and besides I am happy with the power of the 22hp Subaru and I also have a spare 22 hp Subaru to put in if needed.

I am glad you rescued that machine. The guy did so much to it and then gave up from one problem. It seemed a shame.

I suspect it was the case of the straw the broke the camel's back. I think we only caught glimpses of moments of the work that went into this thing.

It wasn't "one problem", it was just the last problem.

I agree. I was very impressed with his work and efforts. I did not mean any criticism. I hope he feels good that the machine is working and in use. I think I would in those circumstances.

personally I would like to put a Kubota super mini series diesel in my 425 if and when the Subaru meets its D.O.D. dimensions look a little smaller than Subaru, I am sure new motor mounts and pump mounts would be in order to complete the transplant

Agree. I bought my forks and stump grinder from him.... Unfortunately, it was so dang cold and snowy when I went to get them that I didn't spend a lot of time looking at or discussing his "PT-429"...

It's a good home-owner level tool. Not as fast as the big professional machines, but works well. It just takes a while. The carbide teeth hold up real well...
