those that have a L 40 series kubota

[VA MTN MAN]

I just purchased a new 5740 and am wondering if this is normal. On a steep downhill the hydro trans seems to give and go while holding the tractor back. I have a 4610 with hydro and in the same situation if you hold the pedal at a certain point it will hold you back at that exact speed. the new one seems to give and catch. Do yours do that.

Thanks

Haven't noticed it with my 5240 , have a guy with a 5740 doing a job I'll check with him too.

I have the smaller L3240 but have never experienced anything like you are describing.Mine seems to hold a steady speed on down hills.

I haven't noticed that on my L3940, but it's pretty flat everywhere I operate mine.

That is not normal for an HST. What range were you in?

It will do it in high and med , i havnt tried low

Does it let completely go and then grab or does it pick up speed smoothly?

Mine did it until I realized that because I didn't have loaded tires and if I was in 2wd the rear tires would slide. I could hear the tires sliding though, in a caab that could be a little harder.

Doesn't happen on my L4740 and I run on some pretty steep slopes.

Is the HST fluid low, perhaps? If you are on a steep slope, low fluid may be letting air into the transmission circuits, causing it to freewheel intermittently.
