i have a murry mower with a 18 hp twin and a 6 speed transaxle and i have had a pully change done to it and i was wondering if i could make it chaine drive i have a motor cycle motor i want to put on it and i hav the rear wheel and i was wonder if its possable to take the trans axle apart and get the axels out and weld them to the hub on the motor cycle wheel and make it work and use part of the housing where the axle bolts to the fram on the mower and use those on the axles to reattach the whole thing back to the mower any help would be helpful thanks:confused:

First off....Welcome to MLMF, Rusty!

I hate to coin the old phrase Anythings possible...but, from what I've seen it's true.

Usually with a rider mower the biggest problem is the conversion from horizontal shaft drive to vertical (motorcycle engine). Since you've proposed to weld the rear axles, and I assume you'll add a sprocket - You're half way there. Next problem would be your clutch. If your budget allows there are several varieties of centrifugal clutches available for mini bikes and go karts. Although mostly for belt drive, with a little in house engineering you can add a jack shaft to accommodate the belt and with an additional sprocket (on the jack shaft) utilize the chain drive system.

If you have a motorcycle as a donor you may be able to utilize parts like BRAKES :D...which is usually the last problem to overcome! Good luck, enjoy the forums and keep us posted on your project progress.

Rusty,

Since it's not being built as a scary speed toy and will be a designated work horse, I'm wondering how cool you can keep your engine, as the 250 Rebel isn't liquid cooled (if I remember correctly?). Wonder if adding a 12VDC radiator cooling fan would be effective enough?

JJT3 has brought up a good point about limited slip too!

its air cooled i wish it was air cooled it will mostly be a work horse but i do have a four wheeler track down the road that i would take it on from time to time but mostly a it will be use to plow snow or pull wood i have built speed deamons out of mowers before and wrecked a few of them and i have been there done that but i am just wanting to build some thing that i could use for work and maby have some fun with and how could use the rear end as a limited slip i would love to hove that but i think for snow and going thru mud to get wood i would need posi tractoing

Rusty, Not sure how you could use a fully enclosed differential unless you swing the nose up 90° add a pulley and go from there. Here are some quick videos that may help with your build:
