Default What to do?

Good day and I'm looking forward to gaining knowledge from the best cub owners anywhere.

I picked up a hodgepodge of an old cub. The frame is that of a 127, the hood says 107 and it has a B&S 10-hp motor. I would like to bring it back to original (or close), add a front loader and use it clean out the stalls in my hog barn. I was at bone yard and found a K-241 (sn:C-195835 Spec: 46329D). I know the 127 came with the K-301 12-hp, however if my information is correct, the engine blocks are the same...? I acquired the service and parts manuals for both 127 & 107 as well as the parts list for the Kohler 10-hp that listed all the specs.
I got the Briggs to run and tested out the drive on the tractor, everything work good. Changed the hydro fluid and filter first off.. it was setting outside for who knows how long.

When I tore down the Kohler engine , it was obvious someone was in it before. The connecting rod bolts were loose and the connecting rod itself was not the same part number as listed for the spec on the blower cover ID tag. It was a 4705905 with a hole drilled in it and the crank bore was shot... the spec calls for a 4706702 connecting rod. The crank journal need turned and the cylinder bore needs taken out .010"-.020" not sure what I want to do. I'm getting windy here, so Ill get to the point.

Is there any way to identify the block other than the tag on the blower? With what I see, the blower cover could even be incorrect. I work in an iron foundry and know all about casting numbers and cast date codes, but cannot locate any ID on the block or oil pan.

Should I just go for the 241 rebuild or try and do a 301 12-hp out of what I have?

Some day I'd like my grand kids to have it as a remembrance of papap..

Your time your money. I see good used k301's on craigslist all the time. I picked up a good one for 50$ a couple weeks ago with PTO and SG on it.

Best of luck with it

Thanks. I have tried CL without success, unless I want to pay big bucks for shipping. Not.. It's a winter project so no rush. Got $100.00 in the 241. The way it will work is as soon as I get the 241 rebuilt, CL will have a dozen 301's within a couple hour ride.. never fails.

I have 2 K301s and a M14 magnum but they are all "wide base" Kohlers.
I have the same issue I cant find a rebuildable narrow base one to save my life. I too have a 10hp that I "settled" on.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
