    Posted: 10 Jun 2018 at 7:13pm
Twice now on 2 different Facebook pages I have been told that a WD does not need an over running clutch on a rotary mower because of the hand clutch.  I've been told more than once that any and all WD's can be shifted by the hand clutch.  The operators manual point blank says to use the foot clutch to shift gears.  I have been on 1 WD and 1 WD45 that could shift gears with the hand clutch.  Maybe I'm getting old and crotchety, but an over running clutch is the cheapest insurance you can have to avoid running something over in an emergency.  As for shifting from forward to reverse using the hand clutch, how many WD and WD45 can that be done on?  Were they ever designed to shift that way?

I cant answer your questions about shifting a wd/45. I push the clutch in, doesent seem that hard compared to some stuntman tricks a few of us on here have done in our lives, for sure and for certain.
I rarely mess with the non Power Director. I leave it locked up, no problems so far...

I can offer an opinion on people telling you you don't "need" an driveline clutch. Each to their own dealio, but of course you don't NEED one.

Even if I was rockin the gigantic FENDT on a 12 foot mower, id be headed to Princess Auto for a driveline clutch first...never mind a 69 year old tractor with unknown hours with a essentially "add on" pto unit. Not knocking it, I have a hotrodded 1950 WD, love it. Look at it as a " pre-emptive Driveline/Drive train structural deflection prevention/retirement assurance self contained ancillary non-OEM optional unit".

Might help.

The hand clutch on the WD-WD45 are not meant for shifting the transmission/changing gears. They are meant to disengage the axle thereby stopping forward/rearward motion and allowing the pto/hydraulic pump to operate.

I don't need an over riding clutch on the tractor to run my AC rotary cutter because the cutter has one.And yes I've shifted the gears with the hand clutch on a WD-45 just have to hit it just right.

I have a WD45 that shifts just as good with hand clutch as foot clutch. Don't ever use foot clutch even in cold weather. Had a WD that was almost impossible to shift with hand clutch.
Nothing wrong with a overrun clutch on PTO. Good safety.    MACK

I responded to that FB post as well.  The hand clutch was not made to shift gears.  IF you are fast, yes, you can shift successfully, but after we had to rebuild the tranny on our 175, we stopped that practice. 
The over running clutch on the PTO is what is needed.

So....an over running clutch is desirable; whether its on the tractor or the machine!

And.......when you don't "hit it just right" what happens?

I have never been able to shift gears very successfully using the hand clutch with either my WD or WD-45.

For some reason I can do so with my D-17 and that comes in real handy when I'm bush hogging.

When you disengage the hand clutch the PTO can't push the tractor causing you to run over things. So a overrunning clutch isn't needed. A slip clutch is needed for driveline protection. When you hit an immovable object something has to give you defenatly want it to be the slip clutch. An overrunning clutch is not drive line protection. It won't save your PTO gears when you strike that culvert that stops the mower dead. As for shiftling I often shift both my WD45s with the hand clutch. You can't be moving at all and you need to have HYTRANs in place of the 90 wt. the manual says the foot clutch is to be used for shifting. When I'm using the loade to move snow it's lots of back and forth I'm real busy so I use the hand clutch. Keeping the hyd live. When the bucket hits the ground the tractor stops. Change gears start raising the bucket pul the hand clutch and I'm going in the other direction with the bucket on the way back up.

A 2 disc hand clutch probably releases better (most of the time) than a 3 disc hand clutch.  As Dakota Dave says, let the tractor come to a complete stop before trying to shift gears. This gives the clutch discs time to separate. Use of modern day hydraulic/trans fluid is also of benefit for better hand clutch release.

I think what Aaron is trying to say is if you're mowing along and you don't see a deep washout and you go to make a panic stop at the last second, the average driver is going to stand on the clutch and brakes. The hand clutch isn't necessarily the one everybody would pull in a panic situation. It's because of that is why you definitely need the overrunning clutch on the PTO to eliminate the flywheel effect of the mower.
For those who say you don't need one, I hope God sends a guardian Angel to ride on the tool box to save you in an emergency...

Ever since I was a kid, I would run the ol WD45 with my left foot behind me, on the pto guard/step. Once the trans oil is warmed up, I never used the foot clutch. My right hand always resting on the hand clutch lever.
The straight WD trans my not shift as well.

With oil not fully up to temp on a D-Series, it very well can "push" with the PD thrown into neutral. Have had it happen on multiple D15 and D17IV units and no longer mow into tight corners/along fence lines until it is good and hot. Slip clutch or overrunning clutch will prevent this and I run no overrunning clutch on the A-C cutter equipped with slip clutch in front of gear box, but newer Bush Hog is run with an overrunning attached at tractor pto shaft.
If you have any doubt, run the overrunning clutch on the tractor pto splines as they are cheap insurance at 100.00 or less. Good idea to remove it and check it/lube it good occasionally as units sold today are not the quality of the past. And DO check the telescoping travel on the cutter pto shaft as adding the overrunning clutch adds length that is not very forgiving when you suddenly put it in a bind and damage tractor internals.
Easy to cut the newer "oblong" shafts down for overrunning clutch length to prevent binding on a 3-pt. cutter, 5-7" usually does the trick.

I grew up riding on the tool box of a WD. Rode all over the farm with Grandpa, don't ever remember him using the foot clutch or the brakes for that matter. He sat kind of side-saddle with both of his feet on the platform. I also remember him only using 2nd gear and reverse. I still have that tractor, 'I' have to use the foot clutch. Maybe I'm just impatient.

That WD is what got me started on this AC thing.

I have a 45 that you can shift on the fly as the saying goes. BUT, you have to trick it like the old Ford four speed. Double clutch and drop it in, with your hand on the throttle. If they had a foot feed it would free up one hand and it would be much simpler.

But.......when you hit something very unexpectedly, your first instinct may be to hit the foot clutch....an overrunning clutch is a good thing then.

Went to a 1st responder call some years ago where a fellow was bush hogging with an 8N, without an over running clutch, had finished the field and was cleaning up around drop off edge when he backed up to edge pushed in clutch centrifugal force of blade pulled tractor over the edge, it landed up side down on him.
