Question about HST "transmission"

[StrangeRanger]

My L3400HST has always been a PITA to switch between L-M-H.

By accident the other night I discovered that if I have the clutch in and depress the HST pedal to reverse for a moment, release the HST pedal and then try to switch between L-M-H it's about 1,000x easier and slides right in.

So my question is can anyone see any reason I shouldn't depress the HST pedal while the clutch is in? I can't see any reason to not do this, but my knowledge of HST transmissions is non-existant.

Thanks,

Be careful about doing it on a hill, unless you're covering the brake with your other foot (you will freewheel).

Also just be aware that you will be disengaging/engaging a rear PTO implement, if you have one running at the time.

You can do the same thing as the clutch by getting the range lever "between" ranges and rocking the HST pedal... all you're doing is moving one set of teeth slightly to hopefully mesh up better with the other set. That's a trick some of us guys without a clutch use.

DiezNutz is correct as usual, just rock the HST pedal without using the clutch. Remember to let the HST pedal to come back to neutral (middle) before trying to engage the range selector or you will grind the engagement dogs.

On my B2320, I simply let out on the clutch--very slightly--while applying light pressure to the range leaver.
If you haven't already, you might want to try this.:thumbsup:
Your purpose is to alighn the gears for meshing and letting out on the clutch rotates them.

If the turtle to rabbit lever does not want to move I just double clutch, Typically it helps.

I just shake the tractor back and forth with my butt.

Now that's funny:laughing:

I never use the clutch on my L5030 to change ranges. Occasionally, like others, I will depress the go pedal a little to mesh gears.

I realize all the points made about being on a hill and PTO engage/disengage. And the get it between L-M-H and rocking the pedal bit is what I've been doing for years b/c that's what the manual suggested (yes, I actually read mine ) but that works worth poo.

I do try rocking the tractor and that does help somewhat.

But I was amazed last night when I found this little trick. Works sooo much better than getting the lever in between L-M or M-H and rocking the pedal. You can actually feel something "disengage" or "align" in the tranny when you do this. Then the speed lever slips right in.

I'd be interested to see if others get the same results.

While getting use to my L5030 and after reading the manual, yes I read them too, I tried all combinations with the clutch including the reverse and found that nothing including depressing the clutch made much difference so like I said, I just don't use the clutch to change between ranges. I would like to have one without any clutch at all.

No problem shifting to different ranges w/my L2800,taking out 4WD another thing..down pressure fel works the best.

OK. By your own admission, you said your HST knowledge was "non-existant", so without this additional information I had to assume your experience level was "newb" and cover the basics.
Kudos for reading your manual.

Bottom line, if you prefer using the clutch, then by all means, clutch away. :thumbsup:

Ahh, sorry, I meant that I don't know the innards of the tranny.

I have found on my L3240 that raising the FEL slightly while shifting between ranges seems to help make the shifts smoother.I don't know why but I would guess that it takes hydraulic pressure off the transmission.

Hmmm, you have filled tires on that M135X don't you? :laughing:

I have question about Transmission, I have a Kubota Tractor L3350 I thought my Transmission Or Clutch went out ,my bucket also quit working So I changed Hydraulic transmission fluid and new filter everything worked again for a bit then it quit
working again it was kinda merky looking with some partical bits in oil so I drained hydraulic oil out another new filter,if that doesn't work where do I look next . Dorrie

If that doesn't work then come back to this post and I'm sure there are members with knowledge instead of attitude that will be glad to answer your questions. Some times people with no answer get testy and don't speak for anyone but themselves.

The L3350 tractor is a gear-driven machine and would not have Hydrostatic transmission. But they were available with hydraulic shuttle, which is really two hydraulic clutch packs for forward and reverse. They are powered from the same hydraulic pump as the loader, and 3-point hitch lift. So if the pump is starved for oil, everything quits working. The filter is on the suction side so the oil needs to be clean and at the full level. L3350s are getting near 30 years old - many (most) have not had yearly trans oil changes. I think you are on the right track to completely drain and replace fluid and filter. If doing that restores performance, even temporarily, that's a sign that doing it again might well solve it.

 

[Gary Fowler]

Not familiar with your model, but Some tractors have a filter screen in the oil sump in addition to the canister filter. Investigate this possibility on your machine and if yours has one, make sure the screen is clean before refilling with oil. A clogged screen wont let any oil into the filter or pump.
I had a Yanmar tractor once that the clutch stopped engaging just like yours and it was the filter screen that was stopped up. This would only be the case if none of the hydraulics work on your tractor.

Make sure your pedal linkages are well lubed and the zerks greased. This has helped me. C.
