Good write up on Kubota transmission offerings

You can see #7 is my shuttle shift lever. No clutch is needed

I'm surprised your dealer did not go over this with you upon delivery.
Unless you told him you already knew how to operate it.

My dealer did not demonstrate the tractor for me. Said he would but did not follow thru.

I am trying to find someone in the Ocala area that will take the time.


I have found that I put it in gear using the clutch (whatever gear I choose ) and then I am able to shift from forward to reverse without using the clutch

There are no abnormal noises and shifts forward and reverse without issue

What tractor is this on? If it’s an L2501DT it is a it shouldn’t be a true shuttle shift, it should be a manual shift that you have to use the clutch and transmission be stopped to swap from high to low to reverse. You can shift 1-4 with it rolling to swap gears to speed up or slow down as long as the clutch is pushed in.

I'm pretty darn sure I do not have to use the clutch to go from forward to reverse.

I may end up near the tractor again this weekend, work is slow and I don't plan to come in just to sit on a bucket.

I'll update when I know more

If you are doing it in 1st low, yeah, it will do it fine. Once you go to higher gears, it will start grinding. Pretty sure that the shuttle is not synchronized on that tractor, which would help a bit.

The 2501 is not a shuttle, so you absolutely need to clutch -- listen to what people are trying to tell you before you trash your gears. You may get lucky once and a while but it's not the norm. The lever on the left is the range selector, not a shuttle lever.

The L3301/3901 do offer a shuttle option, and I suspect that is what is being denoted in the picture you posted (from common owner's manual?). You may want to peruse the brochure here:

https://www.kubotausa.com/docs/default-source/brochure-sheets/l2501.pdf

You can see the various transmission options for the L2501 and L3301/3901, both in the specs and the pictures.

I have to wonder why you are figuring out your tractor specs after you own it. If shuttle had been important that would have been a reason to go with the L3301/3901 up front.

This should clear up some confusion on non-synchronized, synchronized and hydraulic shuttle shift, we have all three: Understanding Tractor Transmissions - YouTube

My mistake, I didn't have my tractor any where near me and was relying on memory.

I really got the chance to use my tractor yesterday and yes the clutch is pushed in to change from forward to reverse.

The trans. reminds me of an automatic. Put it in whatever gear you want and just shift from forward to reverse by depressing the clutch and moving the shuttle shift lever.

Seems like putting it in 3rd or 4th high and expecting it to go from dead stop puts strain on drivetrain, I'll try to be careful of this

Seems like shifting while rolling ain't gonna happen without grinding gears.

Maybe double clutching would solve this

I see that the description for #7 calls it a shuttle shift - which is a term normally used for forward/reverse i.e. shuttling. Which is normally syncronized and often automatically hydraulically clutched - called "clutchless".

But from the picture you posted that shift pattern makes it looks more like it is a Lo/med/hi Range Shift - which normally requires a clutch and is also not normally syncronized so you have to come to complete stop to shift.
Maybe there are tractors out there with a hydraulically actuated range shift, but I've never seen one made that way. The range shifting gears have straight cut crash box style gear teeth without syncros. They live in the rear end, not the transmission case, and used to be called, "multispeed rear axles".

Just for info, Power-Shift (glide-shift) transmission gears (1/2/3/4) can be easily designed to shift clutchless with small clutch packs because the gears & torque loads are small.
But range shifting gears in the rear end are larger & see more torque. They would have to have much larger hydraulic clutch packs to be made clutchless. Manual range shifters aren't normally syncro either; you have to come to a complete stop in order to shift.

I like the set up cause I can leave it in whatever gear I like, put the shuttle shift lever in Neitral and hop off the tractor easily without having to shut down which I do often.
