RPM Question

[ODZD]

KIOTI Ck2610 - doing dirt work and lifting ibc totes of wood, what type of RPMs should I be looking at?

1800

Whatever it takes to do the work up to 540 RPM speed. If I'm doing work that is taxing my tractor at all, I crank it up. It doesn't hurt it, it's made to operate at long intervals at 540 RPM speeds

Though usually 2200 Is plenty

Are you just talking about FEL work when you say "dirt work", or are you running something like a tiller (pto driven)?

If it's just FEL work, I'd probably run 1600-1800, which would be enough to run the hydraulic pump enough to get full pressure and lift speed.

Since you don't have any emissions junk to worry about (me neither), I don't see the sense in running the engine at max rev's and just burning more fuel for no reason.

 

[ODZD]

Yeah, mostly like bucket work, leveling a few spots off for IBC totes. I only have a bucket and forks so far, so no tiller or anything else. Strictly bucket to level some ground and store IBC totes of firewood

When I spend time moving the manure pile to the compost pile I run a few hundred RPMs off idle. Idles under 1000, I work at 1200 or so. Hydraulics work a bit better off idle.

I very rarely run my M9's at rated (540-1000 rpm). I gage my pto rpm by the task at hand actually but then I have plenty of power at the pto in the first place.... 93 on the stub.

Nobody asked this yet but is the tractor HST or Manual? With HST, you can run the rpm up to 540pto rpm since the tractor speed is independent from the engine rpm, but if it's manual, you may want to work a lower rpm to save from needing to slip the clutch for smooth operation. My DK4020 is manual and I keep the rpm around 1500-1700 when doing loader work. Works fine and is far more forgiving on the clutch than at 2600rpm.

One aspect I don't get concerned about as neither of my tractors have a clutch to worry about. Both hydraulic shuttle with wet clutch packs. Nice aspect of a hydraulic shuttle is the wet pack is self modulating, that is engagement is predicated on load entirely. My days of dry clutches and eventual replacement is long gone.

For loader work, it depends on how fast you want the loader to be. Sometimes I run the engine at PTO RPM (2500 on mine) to get the loader moving fast. Sometimes less rpms works fine.
