I have been a member for some time, but no recent posts.
I have been developing a small agricultural seed drill, with a mechanical lift system. It is for the developing world.
I am looking for a small single revolution clutch, pin clutch or suchlike to lift the soil engaging parts.
As it must be simple, no hydraulics or electrics or suchlike.
The drive shaft rotates at 50 rpm, which is too slow for a wrap spring clutch, roller clutch or suchlike.

Also the operating conditions in the field with dust etc. are too severe for most mechanisms.
This is from a 65 year old seed drill, which is barely satisfactory.
A Youtube clip of the unit in action can be seen at https://www.youtube.com/watch?v=m3eEqIBDXjg
Does any member have any ideas?
Can anyone direct me to plans or drawings on how to fabricate a small pin clutch or similar?
I can supply further details on request.
Thank you.
