The HLA65 is 3.5kg and the HSA86 is 3.3kg without battery or cable. My makita 2510 with hedger attachment weighs about 6kg. Doesn't seem like much but it's almost double the weight into your shoulders arms elbows and wrists. As you get older, everything helps and if climbing a ladder the weight difference becomes even more important. Would anyone hazard to guess what percentage of time you could use the electric gear over a year for hedging? Even if it was used for just a quarter of the time would that still be a saving on wear and tear of the body.
