Recently the transmission on my Rtv900x appears to have seized. The motor starts and runs fine. As soon as I place into either forward or reverse the rtv stalls. Seems to be a seized transmission. Appreciate any thoughts on this?
Some people seem to believe that all diesels are SUPPOSED to idle very slowly. (Maybe they’ve been listening to large diesels too much.). These little RTVs are often re-adjusted by owners to idle at barely-maintainable low-RPM. If so, this one might be dying with the load of an HST that’s also badly adjusted.Maybe you have the parking brake set and it goes into limp mode, then dies?
they are not supposed to be adjusted. Kubota doesn't even specify the low and high RPM in ANY of the RTV literature, nor will anyone at Kubota even give you that information. So where did you get it? I cant' say whether it's accurate or not because Kubota won't tell anyone, I'm only curious.Some people seem to believe that all diesels are SUPPOSED to idle very slowly.

The RTV-X900 should idle at 1100 RPM. Any slower is not good for it. (And at 1100 it also quits vibrating .... it’s only a little 3-cyl.... Run the idle up until it smooths out and quits rattling.
I apologize for bad memory... the actual idle RPM for the RTV X900 is 1300-1400 and any other Kubota product using the 03 Engine is 700-750. (Sorry about the previous wrong number...I edited that post to correct it.)they are not supposed to be adjusted.

I asked about it and it was explained to me that the RPM adjustment both high and low are part of the EPA emissions stuff and that they cannot and will not give you specifications for high or low speed adjustments, and they also went on to explain that the stop screws are wired in a certain position for that reason, so people won't screw with them. Although-some do, and they are on their own from that point. I guess their thinking is that people will go turning up the fast idle speed which would make the engine make more HP, and on the 1100 and 1120/1140 it could potentially put the horsepower above the threshold. Just me thinking out loud, but frankly leave them alone. If the lockwire ain't busted on the stop screws, don't touch.
The engine RPM specs are in the WSM information section, page # I 10.they are not supposed to be adjusted.

Actually, any time the engine is running, the hydrostat pump is spinning with the swash plate in Neutral. The charge pump is mounted to the rear of the hydro pump so it turns as long as the engine is running also. When the Go pedal is depressed, the hydro pump servo tilts the hydro pump swash plate and the hydrostat motor spins turning the Range transmission input shaft even if the Range lever is in neutral.shouldn't seize if simply placing it into gear. The HST should not be turning (or attempting to turn) any of the shafts until you push the go pedal down.
No it idles ok, when I select gear as soon as I take the foot of the brake pedal and push excellerator it stalls. It’s akin to the hand brake being on but of course it’s not.Stalls? Do you mean it instantly dies? ... or do you mean it becomes “loaded” and dies from resistance perhaps...?
If it instantly dies then it sounds as if your shift-lever is mechanically interfering with your shut-down solenoid or key-switch.
Kubota has always posted the High and Low RPMs for the RTVs in both the Operators Manual and The RTV Work Shop Manual for all models.they are not supposed to be adjusted. Kubota doesn't even specify the low and high RPM in ANY of the RTV literature, nor will anyone at Kubota even give you that information. So where did you get it?
