Thanks for the links.
Jon ... that 25 bhp v-twin sounds like it will handle most things.
Ewan ... like the look of the front-mounted version ...means being able to get up close to things while still seeing what's going on .... have a lot of rushes, so need to check 15 bhp would do the trick ... tbough if I tookthe initial clearing very slow and steady things would be quicker for routine follow-up trimming.
Not had a catch-up in a while Ewan ... we should arrange a get together sometime soon.
