Mowing Disengage PTO before idling down?

[TripleR]

I love the passion in this forum -

I thought I was good to my tractor but some of you guys are extreme!! I question if some of you would quickly shut off the PTO if someone was caught in it. I can see the police report now. "Yes officer I saw he was caught in it and after slowly powering down the engine (which of course is the easiest on the machine sir) I disengaged the clutch with an appropriately swift and deliberate movement of my foot (easiest on the clutch). After cutting the offending clothing out of the PTO area I washed and waxed the tractor and parked it back inside my living room. Of course, I called the hospital immediately after that.:laughing:

All depends on who it was; might rev it up to see if I could sling him free...

Most tractors with independent PTO do not have internal ORC's.
Many tractors with independent PTO's do have PTO brakes. The quickest way to ruin a PTO brake is to shut off the PTO at speed with a high inertia load attached.
I want to hear from anyone who has damaged any part of their tractor by idling it down before shutting off the PTO. The notion of damage from that cause is absurd and nothing more than speculation by the uninformed.
It is impossible for an implement driven by an independent PTO to move a tractor forward by turning the transmission if the main clutch is disengaged or the hydrostatic control is moved to neutral.

Do you have a link or reference source, very interesting thread. Thanks

My reference source is 46 years experience operating tractors and probably 40 years of responsibility for maintaining and repairing tractors that my family and I have owned. 17 years of which have been also spent professionally repairing tractors and counseling owners on the proper operation of their machines.
I learn new stuff every day, and do not claim to know everything, but there is some real poor information in this thread.

Finally, a fully correct summation. I would link to Rick on this one.

I have a live PTO, no brake. No over-running clutch either. I try to let the engine rpm come down before I even push the clutch in (2 stage clutch). For one thing, it brings the bush hog speed down to match the engine idle when I re-engage it a few seconds later. For another, it reduces wear on the PTO clutch since both the PTO (being driven by the bush hog) and the engine are turning relatively slowly.

One thought about wear on the PTO - I bought an L3750 (have since sold it) from a guy who let his "Trailer Park Manager" run it. Well this guy was no equipment genius and the L3750 had a Kubota BH on it. As he was showing me the tractor I asked him where the PTO shut off was and he told me he didn't think it had one - Now he put a lot of hours on this machine and lots of loader work - hence lots clutch in and out and the PTO worked great. My guess is that if you are reading this forum you are treating your tractor WAY better than the average operator and although you might have some bad luck you are probably way on the correct side of a good operator. Don't sweat everything - your 'Bota will last a long time!

With a BH on it... There would be nothing with any inertia being driven by the PTO ... therefore no damage could have ever occurred to the pto brake, clutch or over run if there were one... KennyV

I guess you are right but still must have been turned on and off needlessly thousands of times - Also it was a PTO pump so it would have provided significant resistance in starting up - You are right no inertia slowing down.

Verry little resistance starting up. Even if operating into a very restricted line it wouldnt be bad, as there is like zero mass [fluid] being accelerated compared to a mechanical load. Torque spike on the clutch is consequently softer and very short lived.

That's the way I plan to do it from now on, after learning from this thread.

You have a kubota L3940. It has an independant pto which is what many tractors have in the past 20 years. Pushing in the clutch will not be of any benefit when disengaging the pto. In general, if you have to use the clutch to engage/start the pto, then pushing the clutch to disengage the pto may offer some benefit. Otherwise, pushing the clutch when disengaging the pto is little more than meaningless excercise. Then again, we all could use a little more excercise.:thumbsup:

Using the foot clutch doesn't engage the PTO brake.

I'm more interested in engaging the PTO more gently with the clutch.
