B7500 PTO restricting plate

[texblonigan]

Like a good Kubota owner, I took a look at the B7500 owner's manual while waiting for my tractor to get setup and delivered. In the PTO operation section, the manual states that after the mid-rear PTO combination is used (e.g. after using a MMM), the restricting plate should be moved back (I think this will then prevent the mid PTO from being used unless the restricting plate is moved again). Is this really necessary? It seems like keeping the restricting plate offset will allow you to pick rear-only or mid-rear PTO operation whenever you want, without having to lossen the nut and move the plate. I don't have my tractor here, so I am trying to understand this section of the manual. If I interpreted this correctly, why should this restricting plate be moved back to allow only the rear PTO from being engaged?

I'm guessiing that this is a Safety Issue.

I don't own a "buta, but if the restrictor plate is some kind of guard, I think I'd want it on unless I was using the mid PTO.

I had the same question you do. My manuals came a week before my B7500 so I had a good chance to go over them. When I got to this guard thing my first thought was "Well, that's gonna be a pain in the rump". Anyway, when the tractor arrived fron Carver's the plate was in the position that would allow the mmm to be engaged. So I guess I just haven't worried about it. I would also like to know what their thinking is on this doohicky that seems as useful as a muffler bearing./w3tcompact/icons/hmm.gif

I gotta get my book out to see what exactly you're talking about. Restricter plate mowing? ha.

I am curious about that thing, my BX has no restrictor plate and neither does the 2410. Both tractors allow either PTO to be used singlely or at the same time. The BX accomplsishes this with one lever and the 2410 uses two levers. Does the 7500 have a single lever. Just curious why that would be needed, can you take it off and throw it away, I might would.

I just got out my owners manual to refresh my memory. The B7500 pto lever has a single lever with three positions; 1. Rear pto high speed with mid pto on. 2. Rear pto low speed with mid pto off and 3. neutral. I am still having a hard time understanding why you wouldn't want to engage the mid pto. I wonder if they are trying to keep you from inadvertantly shifting the rear pto into high? Would there be some implements where it would be dangerous to do that? This is what one of their !warning messages in the operator manual implies. I guess I can see that but then you say the BX and the 2410 don't have it.......must have been some engineers brain drizzle for this model only./w3tcompact/icons/smile.gif

That's the only thing I could think of too. It sounds like most rear implements use 540 RPM, and if you accidentally shifted the lever forward to engage the rear PTO, you would have the mid PTO running and the rear PTO running at the same time, but at a much higher RPM. Unless I hear different from anybody, I think I'll leave the restricting plate offset so I can choose the rear-only or rear-mid option at will. Hopefully I'm smart enough to remember which way to pull the lever to engage the rear-only PTO.

Ohhhhhhhh, yes the 7500 has the two speed rear PTO--yes it would be dangereous to use that higher speed with most implements like a brush cutter etc so maybe that explains the plate. No--I doubt they had a brain drizzle--the BX and 2410 have their strange quirks also so we don't feel left out. I thought the 7500 had double levers like the 2410 but I guess not, no big deal but maybe you should not throw that plate away after all, can you get it back out of the trash can?

I have it all figured out now, but totally clueless on what needs 960 rpm PTO.

You could operate your 540 rpm implements at a slower engine rpm on the higher PTO speed, and still have the 540 rpm to the implement.
