Just got a new LX2610. Wanted used as I always by used but with a $3000 shipping fee to Alaska and not being able to see the tractor, bought new one Anyway have heard that you should keep the RPM up to at least 2500 by 2 different folks. Today I pushed plowed with the bucket and also lifted and dumped a lot of snow. For general moving around and above work 1500 or even less seems to do the job. What do you think?

I think this question comes up almost as often as "Which grease should I be using?" Many opinions out there as well. Use the RPM's that are appropriate for the job and let the tractor figure out how to deal with it....that's my opinion. Others will say WOT so the engine runs hot and cooks off all the soot so your DPF won't regen as much. However, I believe that it's not good (for any engine) to idle for extended periods of time. So there is my opinionated response worth $0.02

I run my BX23S at 2000, for most 'light duty' operations in the yard (BTW idle is about 1600+-), 2500 for backhoe work, 3000 to get to neighbours down the road.
You need to be above idle to get full power for the hydraulics but WOT doesn't get you(well on my BX23S) any more digging ability or lift capacity. I KNOW you don't run WOT with full size excavators,couldn't afford the fuel costs or repair bills.

I usually run my tractor between 1,500 and 2,000 RPM unless I'm using the PTO, then it is at the required RPM to get the 540 RPM. The lower the RPM, the sooner you will have to regen. If you are running at a higher RPM, you may even see (at least in the Grand series I can see my percentage before regen) drop because of the higher RPM.

Your LX2610 does not have a DPF.

Unless you have a B3350, things should be OK so long as you follow the instructions in the Operator's Manual.

If you have a B3350, all bets are off.

Orange, you're fine in what you're doing. There is no need to be running it at full throttle unless you needed it for PTO.

An engine likes to run in it's max power range. That is not to be confused with WOT.
This is why the manual is a good reference.
A diesel doesn't like working below it's max torque. Lugging the engine is never good. No harm comes from working it max torque.

I have an LX 2610 SU. Like you there is no is no DPF, you do not have to worry about Regen or accumulating soot quickly at low RPMs. The peak of your tractor's torque will occur at the 540 PTO RPM mark - about 2400 engine RPM for our tractors. Obviously use 540 PTO RPMs for PTO driven equipment.

For everything else it is up to you. However, higher RPMs will provide you quicker operating speeds on the FEL, a grapple and etc. Additionally, you may need higher RPMs to give you the push to get into piles, dig, drag a box blade and/or climb hills without slowing significantly. With all that said, I used around 2100 engine RPMs to level a 35 x 35 foot site, and move, spread and level 18 tons of gravel with the FEL and box blade (and a Bosch self-leveling rotary laser kit).

Geezopete! I'm having flashbacks before I get started. Gonna be building a pad for a new shed soon, 24x36 slab with an option for another 12' lean-to on it filled with 8910 fines. Got about 18 inches of grade change to deal with, so that's gonna be a LOT of gravel and fill. Figuring on at least 25 yards. But, I made pretty quick work of about the same amount of top soil for my neighbor. Half of it, I had to move by loader across the yard.

Well I grew up on a farm, but I had not used a tractor in over 40 years. I took delivery of the Kubota on 5 MAR. I leveled the site in about 4 hours on 6 MAR; it was fairly level with a rise in the back of 1 to 1.5 feet. The gravel truck dropped the 18 tons (crusher) on the site on 8 MAR, and it took a couple hours to level/smooth it. Fortunately, I really only have to be precisely level on the sides where the legs will be; the rest is free span.

A pavilion style shed (open, no walls) will be installed 25 MAR.

I used to think that idling was bad for engines until I left a truck idling for many hours as I forgot to turn it off and went on a duck hunting trip. It was a 1999 Ford Ranger. What was interesting was after that it never ran better, like a race car. In the North of AK and Canada they keep the equipment running 24/7 because of the work of starting them in the cold. I think you are right about using common sense and the right RPM for the job. I was thinking I might be lugging the engine which is not good in a gas engine for the crankshaft, Diesels are more built for that as far as I know.

Yes, I noticed at 1300/1500 for 5 hours work with snow the fuel gage hardly went down.

I forgot to mention that I will not be using any farm implements, just the loader for snow and lifting a few hundred pounds. I guess that would be light duty.

Why is that that all bets are off?
The B3350 had some issues with the DPF. The LX3310 supposedly has those problems solved with a completely redesigned DPF and the electronics to go with it. The LX3310 replaces the B3350. The Big BEES are now LX's.

Many (most? all?) B3350 owners have regen issues regardless of whether they follow recommended operating procedures in the Operator's Manual or otherwise.

The reformer based DPF system used on this engine is simply not reliable. Operating at higher engine RPM may help in some circumstances (even though no such direction is specified in the Operator's Manual) but doing so does not prevent all regeneration problems.
