Thanks, bcp! I am tired of the hydrostatic tranny burning up in my John Deere L111. JD kindly replaced the first one but my second is now dead. I am replacing the tractor with a non-hydorstatic ("straight") Craftsman, either the GT 6000 or YT 3000, and was advised by a mechanic to avoid the MTD tractors, to instead pick a AYP manufactured one. Both these are AYP, according to your codes, so I can choose either.
