PERFECT! I have been thinking of such a thing for some time and a search for "winch powered plow" revealed this forum/thread.
I was thinking of welding up a wheeled gadget, with a frame that could be tilted back and a handful of ripping tines attached but I love your idea of just using an old anchor and a trolley.
My only suggestion is to add a remote control device to turn the winch on / off / reverse etc. Some genius will know how to make a remote control to activate the winch.
I can see no problem at all if you attach the winch to a tree (or some fixed frame) and roll your plow away from the winch. The cable is being pulled very slowly by the kind of winches I've seen and though the cable is under some pressure i doubt that the cable can touch the operator if they are standing on the plow side of the beast. I imagine the contraption would be pulled over the plow if it got stuck under a tree
root or similar giving the operator time to use the remote to shut off the plow.
On the "WHY PLOW" question I have recently heard an Australian Darren Doherty speaking about Keyline systems being used in combination with cell grazing (daily movement of herbivores). He asserted that soil depth can be increased by 18" over 3 seasons which he explained was as Autumn / Spring / Autumn. 18" that is bloody amazing. I've studied Keyline - developed by an Austalian in the 1940's
It's a 2 way action. First their is lots off carbonaceous stuff and manure added to the soil and second the hard subsoil is loosened and brought to life. The Keyline plow cuts a 1/2" slit in the surface of the ground and the arrow head device that gets sunk down to the required plowing depth shakes and loosens the soil. This enables air,
water and light to penetrate the surface, enlivening the soil critters, allowing root penetration.
Darren explained that when the animals eat the grass the plant sheds a bulk of its root system. This then becomes soil fauna food, decays, and thus opens more pathways for air/water penetration of the siol. I had previously heard of 4" of soil depth in a year but 18" is staggering.
A bulk of the property I'm considering buying is stony
land with only the pioneer species of scrubby hardy quite useless plants colonizing it.
My question relates to how long I can expect a fully charged battery to be able to deliver the appropriate amperage at this load? Or translated ... how many hours (minutes) of plowing could I get out of 2 fully charged 440 amp/h lead acid batteries.
