If you can make it fit no one will know the difference in HP. Everything my neighbor does with his 20 HO craftsman my 12 HP wheel horse will do. Back in the 30's a full size tractor only had 10 HP. Back when my father sold garden tractors in the 40's the top HP was 5 HP for the bigger tractors and only 2 or 3 for the smaller ones. Then in the 60's tops was around 8 to 10 HP. Now this day and age we are looking some run up to 30 HP. I don't know how Horse power is rated but for some reason they keep raising it. My thought is you can't really look at horse power. If you say nothing to your neighbor he won't know the difference because he sure won't look at the engine till it blows up next time when he gos another 500 hr on the same oil. Its a good thing you are his good neighbor because I would tell him to shove the mower where the sun shine doesn't shine. You are going away above where most people would go on this.
thank you for your answer.
It was my thought that the big HP mowers are just to help sell them.
Now if this was a commercial mower or saw heavy duty use, that would be different.
He just mows his less than 1 acre lot with it.
I am lucky that the shaft on the 14.5 motor is the same as the one on his mower 1" diameter by 3 3/32" long. Now this motor hasn't been ran in a few years but I am hoping that cleaning out the jets will get it going.
Thank you again for your information
