ABSTRACT:
A pipe manipulating tool having an elongated handle and a pipe engaging portion that grips a pipe when a unidirectional force is applied to the handle. A pipe engaging portion of a first pipe rotating tool has a first arcuate jaw pivotally mounted to the handle and a second arcuate jaw fixedly mounted to the handle. A spring biases the jaw members into clamping engagement with a pipe during use. A pipe engaging portion of a second pipe rotating tool has an arcuate member fixed to the handle with an engagement tooth fixed at a free end of the arcuate member for engaging a hook-receiving recess of a bell end of an irrigation pipe. A pipe engaging portion of a third pipe tool includes an engagement tooth extending axially from the handle to engage in a groove recess of a bell end of an irrigation pipe. A stabilizing member is also fixed to the handle so that the tool can be used to pull apart irrigation pipe without gripping the bell end of the pipe by hand. The tools use particular geometries for enhanced leverage to reduce physical strain on the operator during irrigation pipe moving operations.
