Well of course I have a different engine in My DK 35se. It is a 3 cylinder, but it has never come close to stalling and I run it at 1800 to 2000 most of the time. I dunno.

There is something wrong with your machine. I have picked up wet dirt that lifted my rear tires off the ground.

I have a 45 SE when you push it to the max, first sign is RPM drop then black smoke out of exhaust. If you keep pushing it, it will die and need to be restarted. Just remember it is a 45 HP tractor not a Cat D-9 bulldozer

Check to be sure your parking brake is off and your rear remote is not engaged.

James,
For most loose material I can move a full bucket no problem at 1800RPMs. If trying to angle the bucket at a 45 say to dig a ditch out I may up it to 2K-2200. If I try to breakout a packed earth pile at 1800 or so in 2wd or medium range I'll get immediate hydro whine, RPM drop, usual RPM recovery, or complete stall. At this point as an OP it stalls infrequently, and almost always as OP error. Too low RPM, too much material or not loose enough, not in L, not in 4x4. Most often I can dig in in 2wd and lift up as I reach bucket and loader's capacity, while curling or disengaging from the pile by releasing pressure on the F pedal and allowing the RPMs to stabilize, or just bring the bucket up instead of further into the pile, and the lifting of the load will resume. Recently I've lifted so many piles of earth I'm getting to the point if I pay attention to the tractor's sounds I seldom stall. For me at least I can do most bucket work with the 18-2000 range. 2400 or higher is just too much to tolerate for any length of time.
As an example, I recently moved a pile of mixed topsoil, dirt, rocks of various sizes, some buried construction debris, etc. from point A to a point B about 30 feet away to turn over the weed and grass covered pile for next spring. I approached it by leveling the bucket, driving forward at 1800 and in 2wd. As I came at the +/- 6' high piles I would engage the pile at grade and then lift the bucket. I was being careful to avoid any possible nails from prior burn piles of construction debris that had been in the same landing area previously so I did not chop the pile from the top down to grade. This of course was more difficult to do and I was just thinking to myself, "well I haven't stalled her today", when a few minutes later I did just that.:confused3: It would have been easier to cut down from the top of the pile to grade but I couldn't risk having a flat because tomorrow the local fire dept is coming to excavate a dry hydrant at my pond and I need the tractor to be at the ready.
Hope this helps 'xplaining to do...:2cents:

I always go into a pile in either low or med and in 4 wheel drive.

So do I, if I use the same technique with the DK40 as I used with CK30... I stall the DK. I would have expected with more HP I would stall the DK less often than I did the CK, but the opposite is true. This is making me more and more curious as to why. I wonder if there is something different about the tolerances or pressures in the DK vs the CK in the HST unit.
Hmmm, we seem to have hijacked the OP's thread.
I have never had a problem pulling a load nor carrying a load at any time, up hill or down hill and have never had an issue with HST relief. My intermittent engine stalling problems have always been when digging with the FEL. I use 4WD and HST M or L as the situation seems to require. With my efficient buckets I can get by with HST M most of the time and get a full bucket out of a hillside. I have the locomotive power and the bucket to cut into the earth.
The buckets I am using have very efficient teeth and it is very easy to dig into a virgin, small hillside with the bucket down 5 degrees or so in this situation, drive forward in M or L and easily get a full bucket of earth, sometimes lifting the front wheels a little bit and can end up with the bucket teeth embedded into hard clay at the same time. This is when the tractor can stall, primarily due to my inattentiveness and RPMs around 1800. My question is not how to stop this as I know I just need a bit more experience to become more efficient and increase the RPMs or stop digging, assuming I have no hydraulic issues with the tractor- which is the basis of my post.
My question is concerning the hydraulic relief and whether I may have some type of problem as I am not hearing, feeling or any type of sensing of any change in any condition, relating to pressure relief in action. I was expecting the hydraulic relief to come into play before stalling of the engine. And I was expecting maybe a sound similar to when a remote is deadheaded or something, and did not hear any difference. My only indication a limit was reached was when the FEL just would not lift and no sound was indicated when this happened. Just no more lift capacity. And on occasion the engine would stall most likely due to me not having enough RPMs, I imagine.
It could be that my tractor and/or others of similar model do not make enough hydraulic pressure to cause hydraulic relief until RPMS of around the 540 PTO mark. If this is the case, it would explain what I am seeing, in my novice mind.
So, no one has been able to answer my original question, expect possibly the first respondent who thought my indications seemed normal. And they very well may be.
I have ordered parts to create an inline pressure tester and this should answer my questions of pressure relief vs. engine RPMs on my tractor. Others have already answered that I will not hear pressure relief.

I will be curious to see what your pressure check shows. I am expecting a fairly constant pressure, biggest change will be flow rates but I don't know how you would measure that. I will have to pay closer attention to exactly what I am doing, what the engine is doing, the next time I am moving dirt.
