3710 hydro won't shift to low

[Hartless]

My tractor Kubota 3710 will shift from mid to high with no problems but I can not get it to shift into low. Any ideas? Thanks

My tractor is probably of similar age to yours... bought it new in 2002... and the linkages are basically the same. If you are like me, you use medium range a whole lot and low/high, not so much. The most obvious thing is maybe the shift linkage is bound up from dirt and lack of use. This would be really likely if the tractor is stored outside where minor corrosion can also set in at the points of wear.

Try soaking the linkages down with a generous dose of WD-40, PBBlaster, etc. If you look down in the shifter slots, you can see the linkages and where to spray. Let it soak for 10-15 minutes, then begin working the shifter back and forth over its range of movement. If it lets you shift med - high, then do that. Don't try to force it into low. Keep working it, with the engine off, in 2wd, and it will eventually loosen up enough you can try low range. You may need to gooch it with more lubricant, but it should eventually free up.

In the future, try to use the shifter a little more often, just to keep it loose, and maybe give the linkages some lubricant every once in a while.

Thanks but no luck. It goes from med to high and back no problem. But will not budge when I go to shift it into low. Any ideas?

Are you sure the linkage(s) are not bending and binding? have you tried rocking it while shifting?

a spray can of fluid film will help you a lot as it is a better penetrant and lubricant IMO.

The shift from med to hi is basically a straight forward-backward movement of the shifter, but going to low requires moving the shifter to the right and then forward. Exactly where is the hang-up... when you are moving the shifter to the right or when you are pushing it forward? Sometimes mine will catch on the forward movement about 1/2 way in because low range is not meshed just right. Usually going back to neutral and clutching once or twice gets everything lined up (You are using the clutch when shifting, right?).

 

[Hartless]

Clutch is in. I can move the lever over to where I need to push the lever forwarded into low gear. Once it is in place to push forward it will not move forward at all. I have rocked the hydro pedal back in forth and pushed the clutch in and out. It is not in 4 wheel drive.

Check your private messages for some info.

Have you tried pushing your hydro pedal down while trying to shift from neutral to low range?? On my MF it is the solution and the mechanic from my dealer told me to do so. Good luck. Roger

I am not sure if this will help,but on my L3540 when I shift into low it is very difficult at times and I have found that using the loader against the ground to gently move the tractor forward and back as I try to shift solves the problem.
