let me ask here since on MTF 23 views and no replies.

I have an opportunity to pick up a used kohler command 18 hp for less than the cost of machining, pistons, rings, valves, and gaskets for my kohler K301. I was told that the command wasn't used for long and was replaced with a bigger motor (23hp) on a ZTR as the 18 bogged in tall wet grass.

Or do I rebuild my kohler K301 or a K321 (in a box in the shed) and try to get some more power out of it, cam reground, clean and polish head/intake??

anyone know how many FTLBS of torque a 301 has? The command has 32ftlbs.

I really only use the tractor for trailer and plow.

If it were me I would rebuild the original Kohler. What if down the road you want to use your front PTO?

The Kohler is reasonable to rebuild as far as price goes compared to an Onan as well.

I'll second the rebuild, I am not sure about how the command would bolt on to the frame or if the shaft would easily work with the lovejoy and hydro pump.

Also the front PTO is a sure fit on the stock engine, not at all familiar with the command engine.

Specs, pics and measurements will help one of the members to help you narrow down the possibilities.

its not too often you find a 18hp command off a ztr thats a horizontal shaft. its prolly vertical.
the 12hp has more than enough torque. it has a 3.25" stroke.
i just finishing mine for one of my mas***-***guson tractors

This may help you to decide


1. The design of the Hydriv system is identical from year to year and model to model BY AND LARGE. This statement means that a 4023 Ingersoll's hydraulic system cannot put any more HP to the rear tires than a 222 with a 12 horse Kohler can. The 23 hp Vanguard will help you blow snow or wade through tall, thick, wet grass a bit easier than the 12 hp Kohler will because those attachments are feeling the higher HP by way of the V-belt driving them.

2. It's a lot of work to retrofit a different engine compared to performing a simple rebuild. My suggestion is to rebuild the 321 PROPERLY. Leave no stone unturned. Either buy NEW balance gears or leave them out. Bore it, do the valves, springs, guides,seats, new rod, piston, rings, gaskets, seals and bearings. Either polish the crank or grind it undersize on the throw. Have the camshaft checked by a competent machine shop. Replace the points rod. Rebush the carb throttle shaft. New plug, wire, points and condenser. Deck the top of the block and the head.

Once you put a good running Kohler K under the hood, you will be surprised at the difference in performance. In addition, the tractor will essentially remain STOCK and that means it will be worth for more if you decide to sell it.

half way through the snow cleanup the tractor dies and when I try to restart it the engine is turning too fast. I took the plug out and the piston isn't moving.....great I had my fingers crossed that it would get me through the winter before I needed to rebuild. Anyone know a good machine shop in Connecticut? I live in East Haddam but will drive for a good shop, hopefully inexpensive as I am laid-off.

I would call the small engine shops and ask them who does their work
I heard good things about the local Napa. Grind the crank $55, bore $38, valve job $25
You can get aftermarket parts on ebay for about $120

Fellas,
There is no need to mask the brand names of other tractors. We know that they exist. We know that members often collect more than just Case or they own/use brands other than Case.

There is no crime in mentioning other brands in your posts. We just don't want discussions about those brands because this site is about Case. There are other single-purpose sites for those brands.

I just spoke to a friend of mine who is a tractor dealer in Middletown. He said the best small engine machine shop in your area is A & M in Meriden. Gregg

Today is really not my day!!!!!!!!!! So I cleaned up enough of the driveway to barely get in and out with a slowblower (no thats not a typo the thing is slow!!!!) Turn the heat on in the garage and start taking it apart. I'm taking pics as I work to make sure I can put it back together. The camera stops working, no big deal its old and junkie. take the card out and swap cameras drop it, step on it, and crack, 2 pieces. Now I hope i can get it back together.

Back to the original question about rebuilding, I have the 301 in the 222 and I have a 321 in the shed. how many different rersions of the 321 were there? I think it came off of a JD, Will it fit? Can I take parts from my 301 to make it fit? It ran when I put it away but I sold the carb off it.

also when I'm done fixing it I will be looking for a snow thrower.

Most JD Kohlers don't have the alignment boss on the block to center the pump. The crank is the right OD, but too long. Easy to cut off though as the keyway is full length.

I'm planning to use a 341 from a JD on my 644 and am working out ways to mount/center the pump now. Won't be easy but I think I can make it work.

The pan is also deeper, but it looks like it will fit between the frame rails OK. Which is a good thing, as the more oil capacity the better.

But, it would be much better to use the correct block.

I just want the extra 2 hp, that and I have the engine on hand.

Actually Mike, I thought that you were cracking wise but I did not want to leave the impression that this site makes it illegal to mention other brands openly in posts. Right now, everyone is feeling their way around to see how far out the walls are. We are very tolerant here on a good number of issues that other sites are not.

:thumbsup:

Man am I tired...up at 7a and spent most of the day dealing with snow, then I spent the rest of the day fixing the tractor and snow blower. I just came in the house at 10:30p and its nice to sit down. I dug into the 222 pretty good, man is that one heavy beast. I got it out and on a bench to work on. Lets hope I can get it all back together, the clutch pack is ridiculous. I broke one bolt holding the main flywheel shroud on. the engine bolts were funny, one side was falling out and almost wore through the frame (slot head bolts) and the other side was almost impossible to get off (allen head), are there suppose to be 2 different style bolts? How do you take off the Bell housing/pump? In the morning I will try to finish taking it apart.
