I never knew who made it but I used it for years and it worked well for me. Paid 35 bucks for it and sold it for 200 bucks and the guy is still using it.   [Reply]   [No Email]

Got it all taken apart and I am doing some body work on the chute leading to the blower. It was originally red and grey, I am going to repaint it, hmmm maybe some candy apple red and flames...

I have a belt pulley that bolts onto the tractor PTO. It is a Ford unit, but it fits our smaller Massey Fergusons fine.   [Reply]   [No Email]

Walsh was one of many that made these conversions. We never used these conversions feed mill was worn out by then and traded for Wetmore with aluminum gear box and wheels on it. http://www.tractorshed.com/cgi-bin/gallery/oldads_pic.cgi?pic=http;//www.tractorshed.com/gallery/oldads/o50003.jpg&firstrec=1&lastrec=15&Parameter=&mode=All&what=oldads Untitled URL Link   [Reply]   [Send Email]

I took the belt pulley off of the mill the other day, not the easiest thing I have done since it probably was on there 50 years. Thanks, Ed   [Reply]   [Send Email]

In the owners pamphlet for my Ward"s 8" mill, they call for at least a 10 HP electric motor. I also have a very old and very large Century 3 HP motor and hooked it the mill for grins and giggles......it pays to take the advice in the manuals! You have to have enough power to keep the RPM"s at recommended levels....whatever your mill calls for. The speed is required to keep the blower running fast in order to blow the ground grain up into and out of the cyclone. A 10 HP electric will supposedly do the work of a 30 HP combustion engine due the high torque values supplied at a mean constant rate. I"d say that is a fair estimation as you will need a good 30 horses to run a hammer mill and not have to constantly wait on it to "catch up". I have used my little Super A before.....but the mill has to be fed very slowly. My only other tractor is a Deere at 80 horses and while you can"t cram enough in the mill to slow it down......you also burn plenty of fuel in exchange.   [Reply]   [No Email]

The electricity is going to leak out of that motor.   [Reply]   [No Email]

The beauty of an electric motor is it wants to maintain the rpms it is designed for....you know and understand all that theory 100X more than I do. My point is; once the grain goes through the hammers and the load is reduced, the electric motor only has to power the blower and that doesn't require anywhere close to the hammers. I do understand that 10 HP is 10 HP, regardless of the source. On an engine driven hammer mill getting 30 constant horses, it only utilizes that excess power when grinding and during the blowing phase.....that extra power being generated is unnecessary. If the mill is being constantly fed and grinding is non-stop, the grinding load would of course, remain high. For a layman like me, again referring to the owners manual/pamphlet, the manufacturer recommended a 10 HP electric or 30 HP tractor to power this 8" mill. I can only assume their conclusions were based on both math/science and experience. I have also seen electric powered sawmills using 100 HP motors that otherwise would have relied upon a very large diesel engine.   [Reply]   [No Email]
Ole Shovel 10-10-2009 14:04:34 208.246.9.21 169940 Report to Moderator	Re: Belt drive PTO conversion in reply to Ed Kratt, 10-09-2009 14:54:45   Years ago many small line aftermarket companies and those that built feed grinders too like Gehl all made trailer PTO conversion kits. Most had no gear box but just a simple frame, hitch, jackshaft assembly with large V belt pulley on PTO shaft about 3 or 4 v belts and smaller pulley on grinder shaft. I have some old I&T and Farm Implement News books will try to copy a pic out of later for you. If using a gear box you need the correct one for 540 or 1000 rpm PTO of course.   [Reply]   [Send Email]

I knew a guy who had replaced the pto drive on his MC grain dryer with an elec. motor. The jackshaft assy. easily fastened to my grandfathers David Bradley hammer mill. Need a tractor with 1000rpm pto, but that's not a big deal. So- if you could find something similar.....   [Reply]   [Send Email]

Just figure out what rpms you need to have(from the manuals recommendation) and remove the pulley off the hammer mill and attach/modify an old pto shaft off whatever fits the closest directly to the tractor and run at the speed you need. If you think its necessary get an old slip clutch off something and use it in between but next to the hammer mill. Make absolutely you cover the entire drive for safety.   [Reply]   [Send Email]

The mill shaft generally needs 1800-2400rpms. The speed really isn't required for grinding the grain......but to run the blower fast enough to clear the mill as the grain is ground. I converted a Wards belt drive to pto drive using a car axle with a donut tire rubbing against the flat belt pulley, just last spring. No, you can't do it in 30 minutes and you will have to source some parts and do some welding/fabricating. But, the end result works like a factory job! First, I built a frame on a straight axle for the hammer mill to sit upon. On this frame, I built a subframe out of angle iron to support two pillow block bearings, inline with, but below the mill shaft. In these bearings, I mounted a cut off rear drive axle....mine came from a Jeep. You bolt a donut tire on your axle and the tire is inflated to give a tight friction fit against the flat pulley. The stub end of the axle is attached to a PTO shaft and you're in business. I wish I could post a picture and you could plainly see what I am trying to explain. The tire acts as a speed increaser due it's large diameter in ratio to smaller flat belt pulley it rides against. I used a donut tire because it's diameter was perfect, not to mention they are much lighter than a standard sized tire.   [Reply]   [No Email]

Worked fine, easy to line up. Both sold now. Ford 8ns had a belt pulley attachment as I recall. One could probably be fabricated to mount on 3ph. It's important to have a right angle drive so the belt can be lined up and tightened, based on my experience. KEH   [Reply]   [Send Email]

Could just get the belt pully attachment for your tractor and run your hammermill that way. Have fun lining up the belt if the pully is mouned on the rear of the tractor. steveormary   [Reply]   [Send Email]
