Electric Front PTO Resource

Homelite tractors came with an electric front PTO to drive the mower deck, snowthrower, and other front mounted implements. Without it, the tractor isn't very usefull. The rotating assembly on my T12's PTO is shot, and a replacement isn't available (the electric field coil part is). Simplilcity told me that Warner Electric made the PTO's for AC back in the 70's. The bad news is, the rotating assembly isn't available from Warner any longer either. The good news is the help available from Dick Hall of Warner (dick.hall@warnerelectric.com). He provided me with a drawing of the electric clutch that was supplied to Allis in the early 70's as well as drawings for current design clutches to help me find one that should work for my T12. He also provided installation, operation, and troubleshooting guides. The new sytle clutches don't require the field coil to be bolted to the engine block. They mount in compression in a column on the engine shaft (double bearings are used) and require a single bolt or "belt guide type wire" to stop the electric field coil from rotating. A machined spacer may be necessary to ensure the pulley is in the desired axial location and/or the mounting face on the engine shaft is perpendicular to the shaft. I think these new style clutches would be a fairly easy retrofit to any of the large frame tractors and would give another option for driving front mounted implements (a set of idlers similiar to the old single belt snowthrower would be required). If you know the new clutch number, it can probably orderd from J Thomas Distributors (800-828-7980). Warner Electric also has available some new "old style" double pulley clutches (I have the drawing, but the field coil mounting plate doesn't match the Homelite's) I tried to upload the drawing files to attach to this post, but they are too large. If anyone is interested in them, email me and I'll send them to you. Kent, if you want to post them in the "Drawings" section of this site, let me know and I'll send them to you.

I ordered a Simplicity 9020 PTO clutch field for $119 from www.J-Thomas.com Warner electric part no. 5208-451-014 rear pto clutch (same field as the front pto) I will need to epoxy it in as in the attached picture but it is alot less expencive than replacing the whole clutch. michael [img]http://www.simpletractors.com/club2/uploaded/yardarm/clutch.jpg[/img]

        Over a year ago, you answered a question I had about the tool bar for my FDT. In your reply dated Dec 31, 2019  you said the spacer, part #16, goes in the bar to allow for up and down depth adjustment. does this mean the bolt has to be tightened at whatever depth desired or does the bolt slide up and down, allowing the lower hitch to free float?
         If it is tightened so the lower hitch and the bar are rigid, then is the depth to be controlled by the shoes? Or by the lift handle?
        Is there any kind of user directions for the tool bar? The Outdoor Power Manual basically shows how to assemble the bar but not how to use it
