Belt Pulley

I grew around a JD A where the belt was part of the clutch and it ran when the tractor was in gear. I was wondering about the other makes such as Allis, Farmall, Oliver etc. if their belt pulleys were able to rotate with the tractor in motion.

Every one I was ever around could be set to turn when in motion.
 
As Richard said, yes they can rotate with the transmission in gear and the tractor in motion. I have not been around many other brands than Farmall but fairly certain most other brands that had a clutch configuration that was “normal” outside of the Deere two cylinders had the ability to shift the pulley out of gear. If you shut down the belted machine you didn’t want to set there a keep the clutch pedal pushed down so you could idle the engine. The exception to this would be if the tractor had a hand clutch. I think it might be possible that some Minneapolis Moline models turned the pulley all the time when the clutch was engaged driving the gear train.
 
On some of the earlier Minneapolis Molines the pulley did run continuously when the clutch was engaged. But on the later ones you were able to disengage it when not using it.
 
My F14 has the belt pully turning all the time. My W30 had the belt pully turning when the PTO was engaged. I removed the PTO so I could use the belt and not worry about getting caught in the PTO which was right under the seat.

om most tractors the belt pulley could be engaged when needed. you didnt need the pully rotating when doing field work. on them 2 bangers you had to keep the clutch disengaged so the pulley would not turn. and them tractors ran at a slow rpm like 900 rpm and many times it was too slow to run say a thrashing machine without changing the pully on the machine. it did not even have enough rpm to engage the feeder housing clutch. and then the other thing was to get it the tractor out of gear with a tight belt. and also to use the pto the pulley had to be engaged. its just the way them old tractors were.
 
Guess I should have specified the next newer in line units had separate levers for the pto and belt pulley. Like the w series.
 
My 1950 farmall C has a place to attach a pulley. The 5 ft woods mower made a V-pulley and there was a flat pulley that could be attached there.
The same lever that turns the PTO on also turns on the second pulley on.

X2. My job every Saturday morning after chores was to unroll the belt from the stationary feed grinder, put a twist in the belt, put it on the tractor belt pulley, move the pulley gear shift behind the pulley, then get out of the way as dad backed the MM GB until the belt was tight. Then I put a block under the back tire on the pulley side. So I have hands on experience shifting belt pulleys on & off.

And I still
Do that today. Been making chop for the cows since a teenager. Load up the 1/2 ton with a shovel or pail about 50 bu. And then crush it with the w6. I had to line up the belt in summer and winter. Just crushed a tote of wheat for my neighbor last week for his chickens. Used the w6 ta on the crusher. Nothing changed from over 50 years ago. Even the same crusher with the 100’ belt.
 
My case DC it runs all the time, but the pulley comes off easy so the extra weight is not spinning all the time. The clutch brake is actually part of that bulky on those. Anything newer than those models had a shift to disengage the pulley on the case.
