PTO drive wheel dependent

Post by marten » Sat Jun 08, 2019 7:31 pm

I'm on my first year with a Nuffield 3DL and I've used it with a snow thrower (Trima 200) all winter without any problem.

Now I've tested a rotor mower (Farendlose) and the following happened:

1. connected using a regular PTO shaft
2. run the implement, slow speed
3. press clutch and break to stop
4. tractor CONTINUES FORWARD, driven by the momentum in the implement

I believe that when I was using the snow thrower the drive wheels disengaged from the PTO when I pressed the clutch. Otherwise I'm sure I would've crashed into something while the implement was still turning by momentum.

Now, what could have happened to make the 3DL change behaviour? My two cents worth:

a. I'm dreaming, the PTO has always been drive wheel dependent
b. the gearbox is damaged, possibly due to experiments with PTO shaft lengths

My work-around is now to use a shaft with free wheel. This works but I'm of course not satisfied...

Any hints are much appreciated!

Hello,
Think its normal behaviour for a non live drive tractor if no over run clutch fitted to implement pto shaft. Its not only Nuffields which suffer, friend and his major were put in a pond by the Rotavator driving the tractor!
Regards,
Harry

Thanks ploughman! You're probably right. And the reason I didn't experience this when using the snow thrower is presumably because the momentum is nowhere near that of the rotor mower.

common on none livedrive tractors they need an overun on the pto shaft to stop it .
