My 3830 will not hesitate in mid range even on inclines. Low is completely usable (2000 rpm) and basically unstoppable in the right traction conditions.
I haven't read this whole tread, but something has got to be wrong with this machine, or the driver is using the hydro pedel like an accelerator in the wrong gear. -Surely he was advised that he change all filters and move to Super UDT. /forums/images/graemlins/tongue.gif

If I were to just put the peddle to the floor I'm sure it would smoke and bog. Just push it half way or so and I'm not Crapin ya...It pulls just like I said. The grade has been measured via the tilt meter on the tractor.

CTyler, I have to admit, even after the power increase I noted above that I'm guessing is due to the fuel change and break-in, mine would not even think of doing what you say you can do with yours (3.5 MPH in mid range up a 20% slope) with that kind of load in tow??? Must be nice. Even with the 723 and the BH 90 dropped mine wouldn't do that with the throttle pegged in mid range and that kind of load behind on 20%. Reason I know is your total pull weight would exceed mine with just the trailer, dirt and box blade, assuming I had the FEL and BH on and you had just that (no FEL). Mine would do it at say 2200 to 2400 RPM in low range. Pull it that is, speed not even considered. Here's the limits on mine in Mid range after the power increase I noted:
723 FEL on
BH 90 on
(2) rear ballasted R4 tires
It struggles at 1/3 pedal at full throttle in mid range (at least can do it in M now) on a 12 to 14% slope as loaded above and not doing any other work. Maybe, maybe 3 mph max. with an egg on the pedal. Mid range is still a nearly unservicible range on my slopes for all practical purposes for just that reason. All of my slopes actually!! If I go to low and back off the pedal enough it has adequate power but it's just rather slow. It was unbearably slow before the fuel change in low as loaded above on the same 20% slope.
Raymondo is onto something here that few are experiencing. Note that he finally came around to let us know this ain't his first tractor. I'm somewhere in between his problem and what you and others are getting our of theirs. High range on mine was unusable before the fuel change. Maybe now it will actually run on the flat. It wouldn't. It really seriously struggled in high range on flat terrain when I got it but I'll have to try it now. I'm betting Kubota has an issue with a small group of tractors and this power problem or others. It's a manmade product and subject to issues. What I don't understand is the difference in time. Mine was delivered in early December. I also don't understand the 24 PTO HP (per spec) that his tractor is making and the fact that his is notably worse than mine in performance, or so he describes. Raymondo has had his for some time. I'm betting there is something to this and that his complaints are valid. I've run nearly every kind of equipment under the sun over the years (tractors excepted in all fairness) and really guys, never experienced low power like this.
I don't want to admit to the power issues I'm experiencing after dropping allot of coin any more than anyone with a good functioning tractor really wants to hear it. But this is the place with the brains.... and if it can be figured out or stumbled upon... the knowledge or direction is going to initiate here. It sure isn't in this small skull or I'd have his solution. /forums/images/graemlins/tongue.gif Kubota may take this thread the wrong way but I suggest they get someone with real L3130 seat time to give this guy or myself a visit. If we are up a tree, then so be it. I'll be up here to advise you I was just a little nuts ( already confirmed) expecting too much, etc. etc.. I think there is something here for them to learn on their product. An opportunity actually, if they have the sense to exercise it.

Somewhat aggitating but awful good thread guys!!! Speaks allot to all. And it's still a good tractor!!!!!!!!!! Just has some issues. Thanks!!

The power steering pump is not external to the engine....the pump gets its power from the engine, it's just that the power steering doesn't share the same fluid flow as the HST & loader. -Same basic fluid, different pump so the transmission and the loader don't have to compete with the steering for the limited flow. It allows you to steer while working without feeling the strain of another device diverting fluid while you are trying to turn.
If you feel the steering dragging while performing loader work or moving forward/reverse....that is yet another sign that your machine is in need of additional dealer attention.

Raymondo, It is a separate pump and system. And yes, when being asked to work it does load the engine and rob HP that would be available for other purposes. In an unloaded state the HP requirement would be negligable and under load should be noticable at lower throttle settings. I'd have to get the formulas out and scratch awhile and I'd still have to know the pump over-capacity. Maybe 2 or 3HP at real world working load. More at actual pump maximium capacity (4.9 GPM) which I don't think gets fully utilized on the power steering. If it did, I'd say 5 HP. Others may have a better understanding and idea on actual HP draw at full (real world) working load. I'm still new to the hydraulics and haven't finished the course. No matter, it takes something to power the pump. Doesn't go away because it is a separate pump.

Do you really find you need ballasted tires? I'm finding folks ballast their tires simply because others do or they think it's a job for the dealer. I got my tractor unballasted, drove it for about 300 hours. Ballasted it, found very little difference other then needing more power or slower speeds up inclines. Traction wise I got nothing to speak of. Perhaps with such a small engine HP, a backhoe on top of that you might consider draining them. What does the ballast add, 1000 plus pounds in weight? Add a 1400 lb loader, a hoe that is that ball park and your making that little engine do more. I've gone back to unballasted and have a L3830 which adds about 8 HP to the tractor. I'm now at 400 hours, 50 of which were with ballast. My whole place is hilly. My stability seems unchanged.

but I thought endless amonts of dead weight can only be good right...?
