Never know where you will find a trailer in Tx. My son was swimming in our lake, when he discovered a engine buried in the mud. He kept messing with it and found it was part of a pump. He ask me to pull it out with the tractor. Turned out it was B/S 5Hp field pump mounted on a home built trailer made from a 1932 Crosley rear end. Had to have been in the lake for over 30 years. Engine still had oil in it and the tires still had air in them and the axle was still full of grease. Amazing part of this tale is we got the motor running, the pump working and repaired the trailer. Since the little trailer is only 40" x 50" I use it with the lawn tractor.
