PTO Speed

[Soundguy]

Millpond. 3RRL made a good explanation.

I'll also add that not all tractors have a pto capable of multi speeds. Many of the small japanese and chinese tractors do. Many larger fords and NHs do.. but requires a pto stub swap to achieve the 1000 rpm speed.. etc.

Does that make sense to you?

Probably not. The TC55DA has no PTO speed select, it's a fixed 540. Since it's almost a given that the Boomer has a hydrostatic transmission, there'll be no live PTO and no friction clutch. I can't find any TC48/55 spec sheets to confirm it, so I'm guessing some sorta magnetic PTO engagement. Apples and oranges to the OP question. But even if millpond's got the 12x12 shuttle, there still isn't any PTO speed choice. With only 540 RPM gearing available, the 1000 analogy isn't applicable.

Rob yes it does, but here's the hitch. I have only engaged the PTO lever all the way. I assumed that engagement was what that left sliding lever was for, but are you saying that engagement half way is what I should really have been doing. I don't think the display around engagement lever has any
speed settings. I have totally missed the boat on this one. I understand 540 vs 1000 but man I have not seen where I need to regulate that PTO speed.
Can anyone help with New Holland TC 55 DA operating here. Bill And thanks again Rob/Chris all.

 

[millpond]

Chris/Rob/Greg...I've got it now. The TC 55 DA is Hydrostatic 12/12 and there
is no PTO speed variance so I'm good, or at least I've been kinda doing everything right so far. Thanks guys. So I guess I'll never be running anything at 1000. Bill

millpond,
I apologize for not knowing your NH does not have a 2 speed PTO...duh.
But for tractors that do, my explanation stands as posted.

Considering his 1st post does state he was running at a 1000rpm pto setting.. it does tend to confust things here.

This is the point where I like to tell people to get a manual for their tractor.. so they know a few basinc things about it's operation. After all.. why own a few thousand dollars of iron.. and not own a few dozen dollars worth of paper?

Does anyone know what is the smalles NH unit that has dual pto speed capability? I believe the 5/6/7610S series all do. ( I know my 7610s does.. and the manual seems to indicate those 3 models do. ) I guess I had kinda figured the 55 might as it should be a similar sized machine as the 5610s.. course.. with a hydro tranny.. that's a big difference than the 8sp crashbox.. etc..

PTO problems, can anyone help, Please!! Jinma 284LE 2005 vintage, Loader, backhoe, snowblower, chipper, cultivator, plow, log splitter, generator, mower, bush cutter, scraper/grader plow.
Problem: PTO, once engaged, makes a horrible noise (high shrill) and when I press the clutch all the way, it is still engaged. When I disengage PTO, the noise is gone and the PTO is stopped. The speed control for the PTO is in neutral during this excercise.
Worked like a charm for two years clearing snow, I have 62 hours on the tractor.
I have adjusted my clutch, 2.5mm for fingers to release bearing, 2mm for the PTO settings. I have increased the pedal travel by two full turns.
I have replaced all the fluids in the tractor when I first got it. I am in northern Quebec in Canada and do not have a local, nearby dealer.
Any ideas??

Here are some pictures of the settings of the engage lever, the speed lever and the settings on the clutch. I also show you that a simple hanger that you choose and measure will do the trick for a guage of 2.5mm for the clutch fingers adjustment.
The high grinding noise is influenced by the clutch. When I disengage the clutch, (push it all the way in) the grinding stops, when I lift my foot just a bit, it will start up and then stop. The PTO is moving through this excercise, it never disengages unless I pull the disengage lever up.
Help!!!!

There is an inner and outer shaft thru the transmission which is how the dual clutch controls the torque to the PTO separate from the main transmission. The PTO is the inner shaft. You could possibly have a lubrication problem to this inner shaft. This has been noted by several people. I don't recall the exact fix.

You might also get more responses if you start a fresh topic in this chinese tractor forum.

Thanks, I have posted a new thread called PTO problems
I will give the shaft a couple of hits with a rubber mallet and see what happens, maybe the shaft will become loose.
Do you think I can spray some grease in there with one of those spray grease cans? I suspect grease in a clutch is a no no!
Thanks RonMar
