Going to be doing some grapple work…what’s a good rpm to run a new mx6000 where your not forcing regen on the tractor been hogging at 2200 rpm, going through some fuel would like to back it down some for some med duty grapple work, I’m at 25 hrs with no regen as of yet …., thoughts at a comfortable rpm to do this?

I use what ever RPM that does not bog down the tractor. If you go to low it will fight you to turn it back up.

That's going to be dictated by how fast you want to go without slamming the loader about. You want to go fast enough to keep the engine from lugging, but not so fast that you can't keep up with the controls or so fast that your slamming into things and being hard on your equipment. With the emissions, you probably want to run it at the top end of where your comfortable so that you aren't loading up the filter.

Question: I thought many issues with tractors that have the need to regen is that if it does not happen frequently enough problems appear.

Can one do something that forces regen to happen? Is there a negative to an early regen over not having a regen frequently enough?

Just trying to learn something. My tractors both are older and no regen needed or wanted actually...

I could be out to lunch, but I think what happens to folks is, the regen cycle wants to happen but folks either don’t let the cycle complete itself, or don’t let it happen at all. If the machine is working and parameters are met (rpm, temp etc) then the operator may not even notice it happening. If you’re putting around or about to shut down when it starts (or asks to start) and parameters are not met it obviously won’t regen. After enough aborted regens it’s gonna get clogged up. All machines are a bit different in parameters needing to be met and the system to manually force or start a regen. Lugging, cooler exhaust (idling) or generally not working it hard makes more soot, requiring more regens. Running hard could even lower the soot load between regens as it will passively burn it off (some machines have a passive dpf system and don’t regen per se…. Branson is one)

As to the OP I don’t find rpm to effect fuel burn all that much, it’s how much power/torque you’re asking of the machine that effects fuel burn. Obviously rpm is gonna effect hyd flow, so loader control, and with a geared transmission, ground speed!
