This is great forum, really helpful. I have been reading for about a month and have been learning a lot with so much more to go. Zeroing in on a new L3400and need some help. Not quite sure exactly how the Pto controls function and how to use/operate the pto. Kubota spec sheet calls it "Live-continuous running." Have read and re-read the Tractorsmart lesson titled "Power Take Off School" and not sure exactly how it correlates to the L3400. My experience is with a '58 MS 65 with live pto, ie., pto clutch at bottom of the clutch lever, and with an engagement lever on the side of the trns housing. So, with the L3400, is this correct? Depress clutch lever, then engage pto with side mount control (by elbow) and thus have the pto spinning, regardless of subsequent clutch lever and transmission activity. Then, to shut down the pto, down with clutch lever and out of pto with the side mount control? If so, can engagement be feathered with the hand control for such as rotary cutter? Also, what about panic stops when blades meet stumps or limestone? Any help will be greatly appreciated.

I can't speak for the L3400 PTO, but I think it is similar to the one on my L4400. Pull the lever to run, and it runs, push the lever to off and its off. That's about it. Pull it slowly to enage smoothly. The transmission clutch has no connection with the PTO. When PTO is engaged it runs with clutch in or out.

The L3400HST and L3400DT(gear) are different..
The gear tractor has a two stage clutch. Pressing part way down stops the tractor but not the PTO. All the way down stops both. You must push the clutch all the way down to engage and disengage the PTO. Kubota call this live-continuous running.
The L3400HST PTO also requires the clutch but it is not a two stage clutch. You need to use the clutch to engage and disengage the PTO. There is an over riding clutch in the HST unit that sounds like gears grinding when you press the clutch in and have a load running (like a mower). This can be avoided by pressing in the clutch and disengaging at the same time. Kubota calls this live-continuous with ORC (over riding clutch).
A live independent PTO can be engaged and disengaged while moving without a clutch. Neither L3400 model has this feature . The L3400 must be stopped to engage or disengage the PTO since the clutch must be used.
Both L3400's can be stopped with the PTO running.
The Gear unit is stopped with PTO running by depressing the clutch part way down.
The HST unit is stopped simply by releasing the HST foot pedal. The PTO is still running because the clutch is not pressed.
Hope this helps.

Thanks for the replys.
N80; I think there is a difference - Kubota spec sheet lists the L4400 pto as Hydraulic, Live-independent.
CCSIAL; oops, forgot to mention the 3400 in question has the standard trans with 8-fwd, 4-rvse, so the first of your discussion applies. It, in effect, also describes the arrangement on our MF 65, so will be in familiar territory and it will do just fine.
Thanks to both of you for your help.
