Honda HRD536 QX, Alloy deck 21" self-propelled rotary mower. This machine is the designed for larger lawns where stripes are required and a fine level of finish. This machine has a steel rear roller to produce stripes. It is fitted with Honda's Roto Stop facility which allows the engine to be run without the blades going round. This means when you empty your grass box the blade stops and when you return to the machine you only have to re-engage the blade not restart the machine. Very easy to use this machine with the build quality associated with Honda.
