The McCulloch Mac 1-42 chainsaw, manufactured by McCulloch Motors Corp. in Los Angeles, California, U.S.A., was a powerful and reliable tool introduced in March 1961. The saw featured a die-cast magnesium/aluminum alloy construction, a rigid handlebar system, and a direct drive type. A centrifugal clutch made it easy and comfortable to use, while its manual oil pump ensured that the saw was always lubricated and ready for action.
Sadly, the McCulloch Mac 1-42’s reign was short-lived, and it was discontinued in April 1962. However, during its brief production run, the McCulloch Mac 1-42 proved to be a top-of-the-line chainsaw that was well-suited for both professional and personal use. Even today, it is remembered fondly by many as a powerful and reliable tool that could tackle the toughest cutting jobs with ease.
