I had a couple of jobs today at a customer's garden and I thought I would give the 600 a brief workout especially since the head gasket and exhaust been replaced by my mate Chris a few days ago. It fired up first time this morning and was a lot quieter than of late. There was a dead Acer (Japanese maple) that needed to be removed. I pruned the branches off and mattacked the roots around the tree. I slipped on a rope around the tree and secured it to the hitch. The Bolens pulled it easily in first gear and took two attempts. Considering that it is a 6hp Bolens without diff lock I was pleased with what it could do.
