Been meaning to ask this question here for years, just never did.
On the WD tractors they had kind of a two clutch affair.
One was a 'normal' clutch on the back of the flywheel that stopped the transmission of power to everything behind it.
The other was a clutch pack in front of the pinion shaft going into the rear end that stopped forward motion but allowed the PTO to continue to turn.
Is this correct?
Which one was operated by the hand clutch and which by the foot pedal?
Was the pinion clutch mechanical or was there a hydraulic element to it?
Which models had that setup - WC? WD? WD45? Others?
Was it a good, effective, long lasting system?
Mostly I know the Fords.
On the late 8Ns and Jubilees they had an optional "live" pto package that installed in front of the pinion shaft to stop the tractor but leave the pto spin.
There was a handle you pulled to stop forward motion.
They are not very common and finding one that still works is even less common. There was a hydraulic component in the pinion clutch that was prone to failure and parts for
one have been unavailable for decades.
I always thought the Ford ones were a good idea but kind of doohicky compared to a true live pto which was done with a double clutch and dual input shafts into the
transmission.
Were the AC ones better - more robust?
Were they easy to familiarize yourself with (knowing which handle or pedal to pull/push) so as to be effective?
Just wondering...
Thanks for any info.
