I'm glad Kubota did right by you Hamer. Kudos to Kubota for addressing your problem.

Elliot: Everything else about the L3400HST is fine. I have 180 hours with no problems. In my case even the PTO is OK. Almost all my hours are using the PTO mowing and snow blowing.

The cable adjustment can be checked to insure that the lever engages fully. This is a visual check. Ask your dealer to check it. You can engage the PTO without an implement and see if it turns. If your dealer is a good one he should be happy to put a mower on it to test it before the BH is mounted.

If you don't use the PTO I would still engage it now and then just to insure the cable does not freeze up. I'd also lube the cable when you do periodic maintenance.

I will share my experience with the PTO not shutting off with everyone. I saw the cable on mine kinking and lubed it with one of the motorcycle cable lubers (Cable Luber), which by the way works very well on the cable. Just had to loosen the seat belt mount and swivel it out of the way, engage the PTO lever to allow enough room on the cable to install the luber, pull the rubber boot back, and spray the lube in. Forces the lube through the cable in about a second. However, the cable was not the problem. The PTO still would not shut off. I disconnected the cable at the transmission and operated the cable and it moved with no resistance. I then manually operated the lever on the side of the transmission without the cable installed and noticed that it was slow to return to its disengaged position. I don't know if the spring on it is weak or if there is some internal resistance on it, but it just gradually returned to the disengaged position. So what was happening when I disengaged the PTO with the cable was the cable was trying to push the lever at the transmission which was causing it to kink up top. When that happened, the lever at the bottom could not pull the cable. Now when I disengage the PTO instead of forcing the lever up top to the off position, I move it slowly and give the lever at the transmission time to pull the cable. I hope this made sense.

Elliot:

Same experience as ccsial here. I've got 110 hours. A lot of that is mowing and snowblowing and absolutely no problems with the PTO. I lubed the cable for the first time about 10 hours ago and will continue to do so as part of normal greasing.

I am also on the old CAM style.

IMHO The weak points on this tractor are as well known as they are because it is an incredibly popular tractor. While we've agreed that the original PTO cams are not the greatest design, actual failures with them have been few and far between. That said, all newer tractors have the new style PTO cams.

The cable for the PTO and problems with it have been more reported than anything else wrt. the PTO. I wish it were a lever instead. Note that the L3240 also uses a cable operated PTO.

I sure would like to hear from someone that has 1,2 or 3,000 hours on this machine ...and can honestly say "everything is fine"... yes, putting lube on the cable has "help" but it's not 100% (for me) and I worry so much about the PTO, that I shut the tractor off anytime I connect/remove a PTO shaft.

While it's true both use a cable to operate the PTO I think WHAT the cable is operating to engage/disengage the PTO is totally different between an L2800/L3400 verses a GL3240. The cable on the L2800/L3400 seems to be moving a spring loaded shaft whereas the cable on the GL is engaging a hydraulic clutch. Based on Terry's experience it would seem moving the spring loaded shaft on the L2800/L3400 can be a taxing task for the cable and as you suggest perhaps a lever of some kind would be more appropriate for the L2800/L3400.

Ray, no question. I think Terry's post was particularly interesting and helped explain what the root cause of the problem might well be. A lever definately seems more appropriate here.

Does the 3400 have this PTO problem or is it limited to the 2800? If so what's the serial number cutoff for the 3400?

Since no one else has kicked in here I did a quick search and found this:

"The over running clutches with problems was installed prior to serial number 57745 in the L2800 and L3400 HST tractors only. Kuboto has no real fix for the earlier models.
The PTO design after 57745 seems to be improved with no reported problems.

I don't know how accurate that information is. Try doing some searches and maybe you'll find some more info on which serial numbers have what fixes or maybe one of the friendly dealer members will provide some definitive numbers.
