More HP out of XJ2025H

If I'm doing something that I know is about to bog it down I prefer to throttle up before hand. Unless your low range is geared too high you shouldn't be running out of power. My base tractor weighs more than twice as much 1600vs3400 and only has 9 more hp. My loader also weighs nearly twice as much. I've also got loaded tires, and a backhoe&subframe. I can still break traction before running out of power.

If you are working it hard, you should try to keep the rpms at 1500-2000 easy. But more throttle isn't the only answer. Let off the pedal.

Full or near full rpm, you should be able to chain to a stump and easily spin tires in low range and 4wd.

I do not think you have a power problem. You have a rpm and pedal control problem. Keep trying, you'll get the hang of it

Interesting. Thanks for sharing. On dry dirt I really can't remember ever breaking the tires loose. I wonder if there is a problem in the HST? If I tied off to an anchor point, I would definitely bog down instead of spinning the tires.
I'll start with checking the basics like fluid levels. Any other suggestions?

When I'm doing medium size work I usually have the rpms set around 1700 and when I'm doing something I think is going to really challenge the tractor I go up to about 2400-2500. I don't rev it higher than that.

Your relief pressure could cause a lack of power, but since you're stalling the motor that likely isn't the problem. How does the motor seem to run? How does it behave when you load the PTO? Maybe you're not getting rated HP.

Only other diesel I am familiar with is my Ram with 800 pounds of torque so I don't really know what to compare it to. Going off of sound the engine sounds like it's running perfect. All my 3pt implements work fine including my 12 in. auger that that digs post holes like nothing without any hint of a hp shortage.

The absolute only thing I have noticed is that the HST makes a pretty loud squeal if the rpms are too low (under 1300) and you start to push the pedal down and then goes away as soon as you get rolling. It makes this same exact high pitched squeal when you turn the key off and the drivetrain is coming to a stop.

Not sure if that squealing could be related to my problem in any way?

P.s. I really appreciate your guys time and sharing of your knowledge and experience.

Most HSTs whine. I'd say that's normal.

Not familiar with tractor. Does it have some kind of traction control to prevent spinning?

Are you sure if you tied off to an anchor point, give it full rpm, the just ease into the HST pedal....maybe 10% and no more.....are you sure that won't spin them?

Yep, 100% positive. If the anchor is strong enough, the rpms with drop and the engine will bog and the tires will remain stationary. It just acts like is has amazing traction and if it can't pull something it just won't move. No way those r4 tires in just regular dirt have amazing traction but they sure act like they do.
