That's very good going ! What make is it ?and the total cost was only just over £40 including parts. Here's to another 13 years!
Sadly I've never had a chainsaw - I used to manage with the 2' 6" bowsaw but a few years back I hired a reciprocating saw to trim some fruit trees and I've since bought a Makita 18v reciprocating saw - and very useful it is too. This year I needed to cut a new entrance into the low wall at the front of the house - got through 4 masonry blades which were not cheap - very heavy on the batteries, arms, and ears - but it did a very neat job. It's very good at tree roots you can't see - unless you catch a brick and as long as you avoid underground cables.
