I would not recommend any one to run a 540 implement in 1000rpm
I understand that you may be keeping that implement a the proper speed, But you will be doing damage to the tractor....The tractor RPM's are what helps keep the tractor running at the proper temp. by lugging the tractor the fan is not spinning as fast as you need to keep the engine and hydraulics cool, you will end up creating more heat and breaking down the oils faster.
If you still choose to run pay very close to the temp.
Just my opinion!

I definitely agree with Wallace. Seems like you would be lugging the engine more than you think. This can't be good. I would also be concerned with the implement speed. A few hundred RPM's over what the gearbox is designed for and look out! My $.02.

I agree with wallace and hodak. Brush hogging or snowblowing is hard work and running the engine at 1300 rpm is pretty low. Lugging an engine down, even a diesel, is not good. At that rpm, you're not letting the engine develop any power. If what you were running didn't require much pto hp, then the 1000 pto rpm might be a good choice but I don't think in your case.
Everyone has their own ideas. Just my opinion and info I've gathered from several diesel engine mechanics.

I agree with Wallace, with one exception - I have a PTO pump on my backhoe, and on occation I run the pump in the 1000rpm setting (when working with light stuff). I don't think this casues any damage(engine never bogs), however, I have found that it isn't really much of an advantage either. I don't need to run the engine up very far even in 540 PTO rpm mode, so at 1000 it's really just making the hoe jerkier than I'm able to deal with.

The reason I agree with Rick Wallace, is that the tractor is not designed to do tasks at such a low RPM as 1300. Not only does the fan run slower, but the oil is pumping more slowly also. 1300 is practically idle on these engines. A 1000 RPM implement would normally be used at a much higher engine speed, thus avoiding these possible problems. The damage will come over time, probably not right away.

Well guy's my first concern was not to bog the engine down, but if running the tractor at lower RPM causes insufficient cooling,I simply won't risk it, I have to admit do, running at a lower quiet RPM sounded pretty good , from the very happy CK30 owner /forums/images/graemlins/smile.gif...cag

It just dawned on me, DUH!, that I could run my alternator welder at the 1000 RPM PTO speed and forgo the gearbox. I could use a pully maybe a bit larger than the crank pully and achieve the same rpm for welding. On my Jeep that's about 1000 rpm. There wouldn't be much strain on anything since the tractor would be sitting still and I could run the engine at a lower rpm with a larger pully.
