Husqvarna model numbers starting with "2" or "3" are consumer or entry-level models, "4" is for landowners and professionals such as landscapers and "5" is for arborists and foresters. The other two digits signify engine displacement. So the 450 typically falls into the "farmer" class and is approximately 50cc.
It is a powerful all-rounder but a professional saw. It still has the X-Torq engine, air injection, felling marks, snap-lock cover and flip-up tank cap, but it does not need a magnesium crankcase. This is a great saw and a happy idler, making it useful if your work involves picking up the saw to cut and then putting it down while you move the timbers.
In the event of it stopping, you will find the 450 has Smart Start and an Auto return stop switch that automatically resets to the "on" position for trouble-free starting.

Perhaps more than any other power tool, the chainsaw is a matter of personal preference. Depending on the task, different users may want a compact, powerful, top-handled or even battery saw. But with so much choice available, there should be something for everybody.
We put a wide range to test at Bridgwater College's arboriculture department. We look at the Stihl 261 C-M, a popular machine recently improved. Four petrol models from Husqvarna include updated units and the Mark II top handle. Then we consider rear-handled battery chainsaws from Husqvarna and Stihl.
Conditions on the day were warm and sunny. Note: the Mark II T540 XP is for use by professional arborists only and should not be used on the ground. Lacking time to rig up, we gave it a thorough inspection but hope to run it on another occasion.
