I think I found the motor for my Rat Rod project, a Murray LT (137?)
Another "free if you haul it off" mower, stripped out steering gear and deck problems, couldn't believe the motor that's in it! 20hp B&S Vanguard.. :-D
I really don't have any experience with this motor, but I figure with the right motor pulley, good tires and some reinforcements to the frame it should make me a nice (but slightly dangerous) toy! :-)
The John Deere I picked up earlier I plan to fix up for a "utility" tractor to use around the farm, bigger engine (18hp B&S OHV single if plans work out) and a welded dif with some chevron tread tires..
Plans subject to change without notice, depending on what else I come up with..
