B2620 PTO questions

[grizzjeeper]

Any time I move PTO lever from 540 to neutral I get horrible grinding. Happens occasionally moving from 960 to neutral as well when mowing. Is there an adjustment somewhere? ANd yes clutch is depressed. When there is no load on PTO its not an issue... I am perplexed. No matter how gently I move lever it seems to catch...

Any thoughts? Brand new

Note sure if this is your problem, but I used to wait until the implement stopped rotating before shifting. So I'd push clutch in, idle down engine while waiting for implement to slow down, and then shift PTO into neutral once the implement shaft came to a rest. If you still get grinding then, I'd probably get it checked out.

I use my PTO the same as S219, no grinding do it that way.

Ok so as long as i know that you cannot move the PTO lever to neutral until implement stops I am ok. This is the only kubota I have ever owned I needed to do this with. Waiting for a bushhog to stop before moving pto lever or releasing clutch is a PITA.

Thanks.

Instead of going slowly try quickly moving lever to neutral. Once you are to neutral there is nothing to grind whereas in between is a bad place to be. There should be little resistance to this coming out of gear. If there is or you get grinding sitting in neutral take it to the dealer.

The thing to remember is that the PTO gears surely don't have synchros, which is what makes it possible to shift an automotive transmission in/out of gear at arbitrary speeds while shafts are turning. Without a synchro, you will only get a grind-free shift if you can match the RPM of input/output shafts correctly. It's possible to do but takes experimentation and practice. Otherwise, wait for the shafts to stop rotating.

Push clutch in and wait for implement to slow down...

I throttle down to idle, clutch in see the implement has stop moving then i shift the lever to whatever i need it to be


I get grinding when i forget to clutch in or when i clutch in but don't let the implement stop... only takes like 2-3 seconds.

Mine doesn't do that? I just put the clutch in and disengage.
Something not right with yours.

What implement are you running? That has a lot to do with it. When I run my woodchipper, the massive flywheel puts quite a load on the PTO shaft. In fact, if you were to suddenly throttle back the engine, the chipper's flywheel would hold the revs up.

Mine never did that, I could just push the clutch in at any rpm and pull it out of engagement. Don't shift slow! I would get it checked out because that would be a royal pita to have to wait till the implement to stop to disengage.
