Jim,
If you need a chainsaw like that for around the garden jobs you must have a fair sized estate! You could lob down in a day what would take about fifty years to grow in a garden. I have a 100ft conifer hedge, two apple trees, two lilac trees and several smaller woody shrubs that get dealt with by one of these: Titan TTK587GDO 25cc 1.1hp Petrol Landscaping Multi-Tool | Petrol | Screwfix.com
However, if you are trying to kid Carol that by buying a stihl you will be clearing the garden, i must point out that the Titan wont prepare firewood, fell trees, or prepare blanks and so your sneaky little ploy wont work!
