Hi MF you are right the bigger ones are Gardeners Choice, still just as much trouble. I just had another little Gardenline dropped off here, the pile of these hardly used machines is getting bigger by the day. As for fitting Powertorques to them you have the same issue, shaft is 20mm too short. Also had a little side throw Victa slasher left here to get back up into working condition again. Getting a little out of control, for every mower I get rid of 2 more arrive
