no the rpms just drop right off , I did check to be sure the brakes weren't draging
after reading and research I am going to try loosening the fuel line on the injector one at a time to see if it changes the rpm maybe i have a cylinder dead heading ? I won't be back there for a few weeks though

Why get into the fuel injection? The video shows the engine continues to run smoothly as it bogs down. No misfire but lots of hydraulic whine. If you had engine issues such as a fuel delivery, problem, wouldn't you be looking for it to sputter and run rough, maybe smoke, as it bogs down? Your 3010 has none of that. That sounds like some kind of drive train or hydraulic issue, maybe inside the HST, maybe elsewhere.

Do you think I should change the fluid with superudt or it's to late take in to be checked out it ?

I read a posting some time back about an owner who was having trouble mowing up a hill with his l2501.

He was concerned because he was losing rpm going uphill while mowing. He had loaded tires and a front end loader on.

He took off his loader and the tractor did fine. It was just more than his engine could handle.

Before I started messing with the fuel injectors, I would remove the loader and reduce the weight the tractor is pulling.

Always start with the simple things first.

Agree with simple solutions first. Ditch some of the weight - mentioned in previous post - and see what happens.

Think of it like this. How much of the 30 horsepower is taken up running the finish mower? Who knows, maybe 15? So you really only have the other 15 to move your multi-thousand pound rig around. No wonder why it's kinda slow going uphill!

Removing the loader is the easiest way to shed some weight. Factory loader was designed for easy off/on; if you haven't done it before, study the manual and practice some. Probably at least 700 lbs.you'll set aside before mowing!

Even without the loader on, you have a heavy tractor with modest horsepower. Do you really need loaded tires? If not, that's another 900 pounds of dead weight being lugged around. May be hard to remove, but taking almost a ton off the tractor when mowing will mean the tractor doesn't have to work so hard.

Yes the tires are loaded, in the picture its a finish mower, 3 pt is fine, the hst was serviced before I got it has about 100 hrs since. I think they used other fluid because the filters are Baldwin not Kubota? Can that possible be the problem?
Was it serviced at a Kubota dealer? Lack of Kubota (Donaldson) filters is a red flag since they used Baldwin filters (which are still top-tier filters). My issue would be did they use a non-compatible trans-hydro fluid...or remove what they thought was a drain plug that actually had a ball spring check valve that may have gotten dropped and lost with the fluid? The latter could easily happen if the tech didn't know the draining sequence.

Good point , I could remove the weight from the tires if there because I have a counterweight if needed, but in the video I was not running the mower, I have ordered the super udt and will try that first. Thanks

I would like to say I had a b9200 hst that I ran the same mower on and it did not struggle lighter I know but also only 22.5 hp . I don't expect it to be a race car but something is not right I only hope the hydro is not damaged
