I dont understand my PTO and how it is supposed to work...

That Ferguson is built to be a farm tractor, not a compact.....it's not just about hp.

A vote for the Ferguson F40? This will really be embarrassing for the shiny, modern, more powerful tractors to be sidelined for the beat, rusty and dented Ferguson F40 (and not a massey by the way). Kind of the tractor version of "Rocky" where the old guy comes out of retirement and whips the loudmouths..
Plus i have an plausible excuse for the wife now to now not sell the F40, always a good thing. Thanks! I can just leave the baler hooked to that baby.

It is the lunging motion of the baler driveline that is hard on the tractors PTO. Yes, the flywheel smooths it out some, but you'll still notice the rpm ticking up and down on the tractor a little with the baler running. Basically with every stroke of the plunger it is loading then quickly unloading the drive line which creates a hammering action. Think about it this way: the plunger is moving along pushing hay into the bale chamber, as it gets near the end of the stroke is suddenly has to also compact the hay, which takes full power, then, almost instantly it is on the return stroke with no load. This motion repeated about once every second all afternoon long which is why you want a stout driveline. The flywheel helps some but there is only so much it can do. As mentioned above, running a square baler was never in the design parameters when they were engineering and building these compact tractors. A rotary mower is a more constant load, even when hammering brush and small trees.

The 4000 series (even the new ones with 60+ hp) are still compact tractors. Park one side by side with a 5000 series and you'll see the considerable differences in the size of the transmission and rear end. Same with a Kubota Grand L/MX (which utilize compact tractor driveline) vs a M series.

The lunging is hard on the tractor driveline rather than the PTO. Thats why there is a hidden danger in using an HST tractor on a baler. ... The lunge can be enuf to drive the HST into relief with every baler stroke. The PTO drive is gear and much more tolerant of slowly varying loads w/i the capability of engine torque and beyond. A baler comes nowhere near the comparative abuse of the PTO caused by driving a bushog.

Yes, look at the lunging on the driveline, hard to believe they're trying to use a 4 horsepower machine. Don't be standing behind the power unit when it goes into "relief mode". That could get messy.

I would not have believed it if I hadn't seen the "4 horsepower" motor running the baler. Now it did not pack the bales very tight, but it did make bales. I would not have thought a ground driven "PTO" would have driven that baler at all.

I was impressed too, and there were other video's attached to this one of the similar use of the ground drive.
I didn't see any lunging on the driveline.
