The Mountfield SP185 is a 46cm rotary petrol lawnmower which benefits from a robust, powder coated steel chassis, 3 in 1 mowing options and self-propelled drive. The Mountfield SP185 has 3 options for your grass cuttings; the large 60 litre grass collector ensures you have minimal interruptions; with removal of the grass box the grass cuttings are ejected out of the back of the mower; when the mulch plug is installed the grass clippings are reduced into a fine consistency that will break down into a nutrient-rich fertiliser for the lawn.
