I have a belt pulley on my 1948 "ad". if you were around a farm you would use this for all sorts of implements.as for a belt pulley type pto,you would use this on any implement that uses a flat belt. for example a buzz saw .I dont have a winch though.

It would depend mostly on whether  it is a reduction PTO or a regular PTO. The power reduction would be good to run all equipment and the regular PTO is too fast for regular equipment.

I know were there is a winch for a B.

what is the difference between the power reduction pto & a regular pto?If i understand corectly,would not the regular one run at the same rpm as the engine? If thats the case then the power reduction should run at a slower rpm than the engine? just wondering thanks.

That is correct scott. The reguar pto was used mostly for winches and such as the power reduction was needed for farm equipment.

Standard PTO rpm is 540. My Cletrac E has a pto without a reduction and it runs standard equipment - like a corn picker - just fine, so I believe it is in that 540 range. I have not actually check the rpm though.

I have never heard of a PTO being engine rpm, except I think the Farmall Cubs are that way. Plus, they turn backwards.

I checked my bg with regular pto and it was close to engine rpm. I'll check my books to make sure but i'm almost posative that is the way it is. A regular pto would work for running equipment but it might be too fast for some things.

In the Model BGS specifications the Power Drive Specifications states that there is a:
1) Power pulley and it's operating speed is 1150 RPM with belt speed of 3550 feet per minute.

2) Power Reduction:
     A) Industrial with shaft diameter of 1-3/4 inches & 650 RPM
     B) Agricultural with shaft diameter of 1-3/8 inches & 660 RPM

3) Power Take-Off with shaft diameter of 1-3/8 inches & 1150 RPM

The specifications come from a reprint manual I bought from Zimmermans. Oliver Instruction manual for Model BGS Crawler Tractor Serial Nos. 6cooo UP fourth edition September 1951.

Also the parts book shows that the Aqgricultural unit has chain drive for the final and the Industrial appears to have gear drive for the final. And also the sliding gear for engaging to the PTO Pinion on transmision is the same part no. for all the units

Belt speeds in feet per minute were standardized early on. My steam engine ran 250 rpm, but the belt speed off the flywheel was about the same as stated in your #1.

Does anyone know when they standardized PTO rpms?
