How much power difference do you really think between a 10 and a 12 in the same tractor? The one that will be getting the 10 is really a 129 But i guess will be a 109 if I put this motor in. A couple of years ago I knew of a bunch of cub spec Kohlers but I have been looking for one for a year and a half and this is the 1st one I've been able to get.
I have a bunch of wide base Kohlers, to which the guys where I got this one from say are the hard ones to find. Lately not for me
As far as power goes I'm sure there's a difference but unless you were really pushing them it would be hard to tell off hand.
The K241 has a bore of 3.251 and stroke of 2.875.
The k301 " " " " 3.375 " " " 3.250.
Compression ratio is also higher with the K301.
That's quite a difference in cylinder volume so it should make a noticeable difference under load.
