All our chainsaws fall into the two brands, Husqvarna and Stihl. We use a range of Stihl chainsaws especially the specialized MS200 Top Handled Arborist chainsaw. This is a lightweight, powerful and well balance chainsaw which functions exceptionally well for climbers when working around tree canopies.
The powerful 46 and 29 are also excellent saws for cross cutting and blocking out tree trunks. We use the powerful 3120xp Husqvarna chainsaw the largest commercial chainsaw in the world for any large stumps or trunks that need to be reduced in size.
