some hints for buyers - the width in the listing is of the brush, NOT the overall width - so it wouldn't fit through the gate. The instructions are not clear and easy to understand, but we made do with the pictures which are tolerable. There is a lot of loose fitting pins to allow things to be dismantled - after some use I plan on replacing most of them with bolts and nylock nuts.
Use - adjustment is a bit of a trial - you set it up as per the instructions, but then have to readjust after the first 30mins of use (wearing in?) It works VERY WELL on light leaves and small twigs. Gum nuts will work if you set the brush at 20mm overlap on grass. It never picked up all gumnuts on the first pass, but took 3 passes to collect them all. Also tested on a bitumen road to clear up gumnuts - still took 2 passes since it flicks the nuts forward. Lawn mower/tractor did not seem to work hard pulling it, and no issues in use once adjusted and worn in. Brushes appear to be replaceable - not sure if available through vevor.
