Choosing Your Professional Chainsaw
Size Matters
Most arborists rely on 45–55cc saws for daily climbing work. Weight becomes critical at height—anything over 5.5kg quickly leads to fatigue.
Power vs Practicality
A well-balanced 50cc saw often outperforms heavier models in real climbing conditions due to better control and reduced fatigue.
Budget Expectations
Professional saws typically range from £500–£900. Cheaper models often struggle under daily commercial use.
Brand Reliability
Stihl and Husqvarna dominate professional arboriculture due to reliability and support. Echo offers strong value but may have more limited availability in some regions.
Bar & Chain Selection
Lightweight bars significantly improve handling.
