I was given a AC 2 bottom trip plow on wheels, I have an Almond Orchard and have pulled a disc but never a trip plow, how do they work best? Any suggestions? I know someone out there can help.

Interesting answers to your question. Others described the lift mechanism, while Bob and I referred to the 'trip' on the plow bottom. Other descriptions of the lift mechanism are wheel lift and ground lift- same thing, activated with a trip rope attached to the tractor. But, around here, thirty or more years ago, a trip plow was one which had a trip mechanism on each bottom that would release upon hitting a rock or root etc., and would be reset by backing up until the bottom returned to working position. Some plow bottoms had the shear bolt protection, but were not referred to as trip bottom plows.

JMS/MN you may be logically correct, but not in some manufacturer's terminology. I am looking a MF Operator's Manual and a MF Parts Book for a "MF 74 Trip Beam Plow" in which one option has what is termed "spring release mechanism" and the other option has a "shear bolt". Both versions of the Model 74 plow are refered to a "trip beam" plow since the beam "trips" when hitting a rock or stump. One trips by shearing a bolt, and the other trips by spring release.

MG: I have an AC 2-14 trailer plow sitting in my farm machinery graveyard that is probably identical to yours. There were thousands of them. There is a clutch on one wheel (left I think) that raises and lowers the plow through the use of a trip rope. Now, look at the hitch on the plow. If it has a spring mechanism it will drop the plow from the tractor if you hit a rock. Then you'll have to back up and re-hitch. VERY IMPORTANT! The rope must be attached to the tractor with a ring into a spring clip that will permit the rope to disconnect easily. Friend of mine couldn't find the spring clip so he just tied the rope around tractor seat spring mount. Plow hit rock, detached from tractor, rope pulled tractor seat down until rope broke propelling seat upward with my friend on it. He landed on the hood with tractor moving right along and plow sitting well behind him in the field.

Unlike the others who replied, I an going to assume that you are talking about a rope-trip plow. The rope attaches to the seat of the tractor, you give it a gentle tug by hand and the plow drops into the ground. When you are ready for the plow to be out of the ground, just give that same rope a tug, and up it comes. It really is a pretty slick operation, provided everything works as it should. If you get a chance, visit an antique tractor show where these old plows are being used. This would be the best way for you to witness first hand just how they work.

Keep in mind that you must be moving when tugging on the rope to raise or lower the plow.

Don't know if ours were just wore, but I'm thinking all did it. Yes you have to be moving to raise it -----but these clutches drop the plow or drill when you pull the rope moving or not. Leaving furrows in grass or hayfield to get it up again. Kids shouldn't pull these ropes or can get hurt. The safety ring is best but we used to just attach it to the seat with a piece of twine (hoping it was worse than the seat), then we'd make sure to grab the rope and not the twine. Bill

Bob is exactly correct. However, there is one more kind that most people call a "trip" plow. There is a shear bolt for each bottom. When you hit something solid, the bolt shears, you lift the plow, pull the bottom forward and put in a new shear bolt. One model I know of like this is the MF Model 74 plows.

Do you mean trip to raise and lower the plow or a trip bottom.

Older plows had a breakaway hitch, where the whole plow disconnected from the tractor if it hit a rock or other obstacle.

Then, there were trip plows, where just the bottom that hit an obstacle would trip back to avoid damage. You had to stop, and back up to reset the tripped bottom.

Then, of course, there are the more modern auto-reset plows on which a tripped bottom is automatically swung back into postion after the obstacle is passed by a heavy spring setup, or a hydraulic cylinder kept pressurized by a nitrogen-filled accumulator.
