: : : Does this tractor have a live PTO? If not, which of the 600 series tractors has a live PTO. Thanks for any info. : : Some folks are confused by the term "live". Not to say you are but for instance, the Ford "N" series tractors had to be moving in forward or reverse for the hydraulic pump and P.T.O. to operate. All 600 series tractors would operate equipment with the tractor at a dead stop and in neutral as long as the P.T.O. was engaged. : No, you're the confused one. "Live" means whether the hydraulics/PTO stop when you step on the clutch. In the Ford N's, neither the hydraulics or the PTO were live, but they do work when the transmission is in neutral. For example: pushing snow with N and back blade you would drive in reverse until the snow its pushed into the pile, step on the clutch, put the tranny in neutral, then let out the clutch to use the hydraulics to raise the blade, then step on the clutch to put the tranny back in gear. : All Fords after the 8N (NAA's, 600's and later) had live hydraulics. 600's had live PTO if they had a 5-speed or select-o-speed transmission. The 4-speed transmission does not have live PTO. : The live PTO on the 5-speed Fords is accomplished with a two stage clutch. Depressing the clutch halfway stops power to the transmission for stopping, gear changes, etc. while the PTO keeps running. Fully depressing the clutch stops power to the PTO. Sorry dwb, RMD is right. Boy did I put the horse before the cart on this one. I guess I misunderstood when I researched the design differences between the "N" series and the Fergusons. I think the book I read had misleading information when it came to this subject. You spanked me on this one RMD. Thanks for setting the two of us straight.
