The McCulloch Mac Cat chainsaw was first manufactured in 1990 by McCulloch Motors Corporation, based in Los Angeles, California, USA. It was introduced as a compact and lightweight chainsaw that was easy to operate and handle, making it ideal for homeowners and DIY enthusiasts.
With a 2.1 cu. in. (34 cc) engine displacement and a single cylinder, the McCulloch Mac Cat chainsaw was capable of delivering enough power to handle most light to medium duty cutting jobs. It featured a rigid handlebar system for improved control and a chain brake for added safety during use.
The chainsaw was constructed using die cast magnesium, which made it lightweight and durable. It also featured an automatic oil pump with manual override and a flocked wire screen air filter system, making it easy to maintain and keep clean.
