Converting Tiller to reverse rotation

Are you reversing the rotation of the tines ??? that will pile dirt up between the tiller and the tractor.... My NAA has a Howard gear in the tractor... It is for tilling by reducing ground speed of the tractor... If you have a Sherman 2 or 3 speed.... under, direct and over, your PTO RPM should change depending on which position the Sherman is in.... The Sherman in my NAA changes the PTO RPM from 0.66 - 1.0 - 1.52 ... Try Over in the Sherman and 1st gear in the tranny... Or a step up gear on the PTO output.....

The sherman in an add on in front of the transmission. And the PTO is transmission driven.
So yes, stepping up the sherman increases PTO speed, but ground speed in first increases by the same ratio. So it wont do anything to help the fact that the tiller isnt running much faster than ground speed.

Just an idea that comes to mind but what about a #60 or 80 chain driven jack shaft a guy could gear it any way he wanted as far as forward rotation anyway. I would need to be offset but on a tiller that shouldn't be a huge issue. I see it in my mind but haven't reasoned out all the problems its just food for thought.

I thought about that, as I have pleanty of 60,80,and 100 sprockets and chain.
The problem is the existing gearbox. Not wide enough to a very big sprocket in, no where to put a good tensioner without a LOT of modification, and the shafts are currently splined, so those would either need turned smooth and have a keyway cut.
ALOT more work than reversing the direction.

Heres a start on repairing the shield
Peice of 2 x 2 x 1/4" angle laid in there. That should make it pretty ridgid.

Sounds like a fun project, I hope it works out for you.
It will be fun to see just how tough the old rice tiller is. It should hold up for awhile, but I wouldn't abuse it too much. I'm betting the old ford won't like it much either. Reverse tine tillers need a little extra horse power.

it looks like its built well. its only 54", so the ford should do fine.
