slip clutch

[dieselsmith]

I have a 2210 and want to run a buddy's brush hog but the pto kicks in way to hard on my tractor, I don't see how you could ease it in on this tractor. The brush hog is 5', I know that is too big, but it is very light work I want to do with it. Is there something to buy to take the hard hit of running pto implements?

What RPM are you at when engaging your PTO? I engage at Idle or just above and then bring the tractor up to PTO speed.

You should really fix the problem, rather than treat the symptom. If it's not simply a matter of letting your foot off the clutch too fast, you need only back off PTO clutch engagement point a turn or two.

Or did they put an electric clutch on that thing?

I tried at an idle and it stalled the tractor out! I did not know about adjusting the electric pto engagement.

that 2210 has only 17 PTO hp. A five foot rotary cutter normally needs 25 and up. The other thing, is the 2210 rear PTO has two speeds. You're using the 540, right?

But a slip clutch won't do you any good anyway. When adjusted correctly, it's job is to "slip" after the blades are spun up - when the blades hang up on something strong enough to do damage to the tractor transmission.

I think the rear is 540, I don't think there are two different speeds for the rear pto. It has mid and rear pto and is selectable between mid, rear, or both at the same time. If you can select the pto speed, I don't know how to do it.

You're right, I misread the 2210 spec sheet. My feeling is that you've got too much money tied up in that tractor to damage it by trying to spin up somebody else's mower - especially a five footer.

You know, I think you are right, willl a 4' be ok?

What other 3pt pto driven implements do you run that you feel engage "hard" with your 2210, 23hp hydro, with 17.7 pto hp @ 3000 eng.rpm, 540 @ rear pto? Now a 5' rotory cutter is big for tractor but you should be able to sit on your lawn and spin it with your machine. It may show its lack of power as you cut. bogging down the engine. I have a 30hp, 25.5 hp @ rear pto and I run a 5' KK rotary quite well. My cutters owners manuel states: with tractor at idle speed, engage the PTO and slowly advace throttle to 540 PTO RPM. and it works well. I did engage at 540 RPM a few times on accident, after stopping for a break and that rotary cutter bounced around trying to rip my 3pt hitch off my tractor. A rotory cutter has 2 very heavy hinged blades that need the spinning cintrifical force to find balance. On mine and all that I have seen operated you engage at a low RPM and the cutter will wobble some then smooth out as the blade find balance then speed up to 540 PTO RPM. I engage none of my implements at full 540. I engage at lower RPMs then bring them up to speed. Now I think I would look at that cutter off the tractor and make sure everything turns freely, good luck

I would believe that a 4' is the manufacture recommend cutter for that tractor

If you think there is a problem with the tracotr, check with the dealer, you're probably still under warranty. Otherwise, John Deere recommends the LX4 4' rotary cutter for the 2210.

I have one on my 20 PTO HP JD 770. I engage it at an idle and feather the throttle when I engage the cutter so it doesn't stumble. It won't stall if I don't but giving it just a little throttle at the clutch friction point engages it smoothly. I then bring it up to 2,600 rpm, (540 PTO Speed). The LX4 cuts brush 7' high with only a slight rpm drop in heavy stuff. I do not cut ny "trees", but it sure does a good job on mixed hay, weeks, thistle and wild mustard. While a slip clutch costas more than a shear pin model, it saves a lot of time, especially if you're hitting rough stuff that you've never cut before. To me it was well worth not having to replace probably a dozen shear pins.

The problem with using someone elses implements obviously is you don't know what shape its in. If the slip clutch is "frozen" it's the same as not having one, and your PTO will bear the brunt. It's hard to tell if the slip clutch is working until you hit something, then it too late. If it's got a shear pin, if the pin is too hard, it won't break, but the PTO might. Something's got to give.

By the way, what did your deale or the owner's manual say about the cutter.

Probably a 4' hog. I don't see how you can ease the pto in. All I have is a knob on the dash to pull to engage it, not a lever to ease it in.
