I have a 5 HP B&S engine and I wondered if it would be enough power for the MF 14 to pull a lawn sweeper, cart and 36" roller (under 400 lbs.)? Not for long term, just to get it where I could do some work with the tractor.

I'm not 100% sure that I will sell the tractor. If this engine would work, I could use it till I get the K321 rebuilt.

If you can hook it up without having to alter things too much I am sure it will power it provided it is gear drive.
I once saw a wheel horse repowered with a modern 5 hp and it did a lot of ground engagement work.
Then you could always reinstall your other motor.

The first 110 John Deere I ever ran only had an 8 hp motor and we thought we were in tall cotton and never thought it was underpowered? I sometimes think too much is made of HP and is more marketing than necessity.

My son and I put a 3 hp push mower engine in a Murray 12 hp tractor once, changed the belt pulley so it would go faster than stock. Worked great for a go cart. My son used it for a few years. Noel

All you can do is try it. With a hydro there is a certain amount of loss in the system but it's likely in the 20% range which would bring you down to 4hp. There is also a certain amount of power required to run the pumps when you are not moving.  It would likely have trouble with quick changes in speed but I for one would like to see if this would work. If you could up the HP to 8 or more your chances would be better. Not sure if people use snow blowers in Indiana but they are a good source of cheap 8 HP engines, especially in the summer.

Thanks everyone, I think I just might try it.

If it's not enough power, I won't hurt the hydro or transmission will I? The engine should just run out of power, right?

As long as the rotation is right, should be fine.

Should a B&S engine shaft turn the same direction as a Kohler?

Yes, but some of those tractors (no guru here, don't know what ones) may have coupled to the flywheel end of things. Just verify rotation and orientation before hand.

Or someone could post that knows what they are talking about :D

That's how mine is, the drive shaft bolts to the flywheel.

You will probably need to build an adapter as there is little chance that the bolt patterns will be the same.
The 5 does have a way to bolt up to the flywheel?

5hp will do what you want, but as Alan said, might be difficult at best to couple to the flywheel side.

I can't say for sure, but I don't think I could bolt it to the flywheel of the B&S. And, since it is recoil start, it would probably be difficult. I'm I correct in assuming that?

Yes, with rope start, it would be almost impossible to use that engine.
