set up of plow is important.
but, from my experience working years with the old AC snap couple hitch system.
first thing you want to do is crawl under the tractor and be sure the snap couple hitch hook is in excellent working condition.
Insure all the hook cotter pins are in place and in good condition, plenty of tension on the hook to insure it stays hooked to the plow.
over the years I have heard of a number of the under belly snap couple hitchs come unhooked while plowing and the lift arms staying hooked
then the plows can come over on top of you.
just a heads up, be safe!!!!!!!!!!!
install new springs on the lift arm couplers to insure they stay connected, as they can come unhooked.
the snap couple hitch can be quickly hitched to the plow, but it can also come unhitched from the plow quick, if you hit a stump or rock, etc:
