Caption: Wooldridge Manufacturing offered three different models of cable operated ripper depending on what its customers required. This is a model RS-3, smallest of the three models, designed for use behind tractors of 70 horsepower or greater. Wooldridge manufactured these up until they were bought out by Curtiss-Wright. ⁣

Caption: The Baker Manufacturing Co., were a preferred supplier to Allis-Chalmers right up until 1955. They made only one type of towed ripper, the model 500, designed for use behind an Allis-Chalmers HD-19 or HD-20. The model 500 was discontinued in 1951.⁣

Caption: LaPlant-Choate, a fierce rival of LeTourneau, also offered cable operated towed rippers.⁣
This particular model bore a close resemblance to LeTourneau’s K-30, but didn’t last in production beyond 1946. ⁣
