Cub Cadet 72 upgrade to 10HP
 

Hi I have the chance to buy a running Kohler K series 10HP for $50. My Cub 72 with the 7hp is a fine little motor but wouldn't mind the couple extra HP.

Will that fit in my existing frame with little headache or is this a lost cause?

I'm not cutting the frame or any of that. Like my little Cub too much haha.

Thanks!

Pretty much a drop in if its a k301as

What is this new motor from? Another cub? Blower housings were different on narrow and wide frame k series as the coil mount is lower on the narrow frame than it is on the wide frame and won't work unless swapped, also a few more subtle differences.

If the 10 horse is from another cub cadet it'll bolt right in. Only real difference will be your throttle cable. It's longer and connects differently on the k161/k181 engines. But it's a very simple fix.

And that is if it's a starter generator 10 horse. If it's a ring gear starter not so simple..

Wouldn't it be a K241? K301 is a 12 HP.

K241. 301 will fit to.

Yep finally heard back and it's a K241 for $50

But what's it out of? If it didn't come out of a Cub then it will take some serious work to put it in.

Came out of Cub 100 series

I repowered my model 72with a k241 out of a model 100. Turned out great, no problems as I retained the model 100 wire harness and voltage regulator. Basically, I have a "newer" edition of the classic model 100!

Nothing like a all-gear drive, round fender IH cub Cadet, stronger than the hydro drives for sure!
