The Clyde Stump Puller

For efficient and economical land clearing, a mechanized stump puller machine could clear three to five acres, but were rendered obsolete by crawler tractors.

In the April 2016 issue, we looked at one of the machines by which log loading was mechanized in the early 1900s (learn more, 12187386). A leading builder of early log loaders, Clyde Iron Works also offered a mechanized solution to a related problem – efficient and economical clearing of large land parcels.

The Clyde Steam Stump Pulling and Land Clearing Machine sat on skids and was essentially a modified stiff-leg derrick with a boom that swung left and right 90 degrees. It had a two-speed pulling drum carrying cable from 1-3/8 to 1-7/8 in. (3.49-4.76 cm), depending on the model of the machine, and operated at a speed of 25-45 ft./min. (7.62-13.72 m/min.) while pulling a stump out of the ground. When the stump had been loosened, the pulling drum was shifted into the higher speed without stopping the engine, and the stump was skidded to the machine at 200 ft./min. (60.96 m/min.). On arrival, it was hoisted and swung onto a burn pile, while an out-haul cable carried the pulling line back for another pull.

This machine could clear 3-5 acres from one setting, and when that work was done, the pulling line was hitched to one or more sturdy stumps in the desired direction of travel and hauled in to pull the machine forward. Given a project large enough to warrant use of a machine this size, it was the most cost-effective per acre means of doing this work. Machines like the Clyde Stump Puller were rendered obsolete by the advent of crawler tractors equipped with dozers, rakes and other attachments for land clearing.
