  • Method of using a hydraulic stake puller
    Publication number: 20220170489
    Abstract: A method for using a tool to extract tent stakes from the ground is disclosed. The tool has a portion that houses the motor and hydraulic fluid tank, and a hydraulic cylinder portion the user holds against a tent stake and operates to pull the tent stake. Hydraulic hoses connect the two portions. Separating the motor from the hydraulic cylinder allows the user to manipulate just the portion performing work on the tent stake without having to also lift or stabilize the larger and heavier motor portion. Rotating a handle causes the hydraulic cylinder to extend or retract. A hand guard may be present to prevent accidental crush injuries. The tool is designed to fully extract a stake in two strokes of the hydraulic cylinder.
