This is another illustration of the No.52 plow. This one has the standard steel wheels. The No.52 came in three sizes: with two 12" bottoms, two 14" bottoms, or two 16" bottoms. The best way to tell which one you have is to measure the distance between the main beams.
Here's how a trailer plow works: When you get to the end of the row you pull the rope that is attached to the lift mechanism that is built into the hub of the wheel that rides on the unplowed land. As long as you are still MOVING, one half turn of that wheel will lift the plow out of the ground. After you turn around, you pull the rope again and the plow bottoms drop into the ground. If you pull the trip rope too long, you will do a FULL cycle and if you are not looking over your shoulder you will go down the row with the plow UP, or WORSE, you will make your turn with the plow DOWN!! How do you suppose I KNOW about this??
