Livestock chute puller and a method of using the same
Abstract
A cart enabling a single person to pull a livestock chute across the ground. The cart includes a bar having a handle and wheels provided at opposing ends. The bar includes first and second members pivotally engaged together. A crossbar pivotally mounted on the bar includes first and second arms configured to engage handles on a lower front end of the chute. When the bar is in a collapsed position, where the first and second members are disposed at an angle to each other, the first and second arms are insertable into the chute handles. When the bar is moved to an erected position, where the first and second members are aligned along the same plane, a force is applied to a footrest on the bar. The arms lift the front end of the chute off the ground and the cart's wheels move under the front end of the chute.
