If you want a more powerful chainsaw that can rip through harder wood and bigger trees, look at farm and ranch saws. Features include adjustable oil flow, which allows the most control of chain and bar oiling depending on cutting conditions.
Farm and ranch chainsaws are for professionals who don't want the big price tags and homeowners who cut trees and wood on a regular basis. If you're an everyday chainsaw user, step up to a professional model.
Despite what you might think, professional chainsaws are light-weight, making them easier to use all day, everyday. Balanced, ergonomic design and top handles makes them easy to maneuver.
Built to withstand the rigors of professional use, pro-grade saws have longer warranties to protect your investment. These saws are top-of-the-line, so if you're an occasional arborist, it's more saw than you need.
