A history of mobile slasher development

Abstract

This thesis describes the development of the mobile(portable) slasher from the early 1930*s to the present time. Three different types of portable slashers are explained: 1. Table type slasher. 2. Swinging or Drop Circular Saws type slasher. 3. Portable Motor(Chain) Saws type slasher. These three types of slashers are shown in many examples such as the Waterous Portable Slasher, "Paul Bunyan" Wood Sawing Machine, Marathon-Nesco Slasher, etc. Then Marathon Paper Mills Ltd developed the self-loading, end-haul, self-propelled, circular saw slasher in about 1950 which is basically the same as is used today except for a few changes. Also detailed are the timber harvesting companies which used the mobile slashers and had them built to their specifications.
