Mountfield AL511 PD Mulch Plug
Mulching grass is a great feature! It saves so much time and can make mowing the lawn more than 30% quicker as there is no need to keep going to the tip to empty clippings. You may well ask “Will I see the mulched grass?” and the answer is “No!” Mulched clippings are blown down into the turf and are not noticeable provided the grass is cut regularly and not on the lowest setting.
Some owners prefer to collect grass cuttings on areas close to the house to be certain that children or pets don’t carry them inside and then use the mulching facility on all the other areas. Switching between collection or mulch modes is extremely simple and takes less than a minute. To mulch, just remove the collector, insert this mulching plug into the discharge chute and replace the collector.To return to collection, simply reverse the procedure.
Mulching the grass allows the clippings to be recycled, improving the soil as they decompose forming a natural fertiliser high in potash and nitrogen. You will notice a marked improvement in your grass as this fertiliser takes effect over the course of the cutting season.

Mountfield have been one of the UK's best selling lawn mower brands since the 1960s. They’ve built a reputation for quality and reliability through their wide range of products. Mountfield first began manufacturing rotary lawn mowers in 1962 at their premises in Maidenhead, Berkshire. Despite the fact that today’s machines have very little resemblance to their ancestors, Mountfield garden machinery has always been made with high quality and good value for money in mind.
Mountfield aim to make gardening as pleasurable an experience as possible, and manufacture their products accordingly. Over the years they have continually developed their products to ensure they are both meeting and out-performing consumer expectations. Today they don’t just specialise in manufacturing of lawn mowers. They have a whole range of products to ensure that many gardening needs are met efficiently, from ride on mowers, to multi-tools and garden shredders.
Mountfield's lawn mower range is extensive. With hand pushed models, self propelled models, petrol, electric and cordless, there is something for just about everyone.
They produce 2 types of ride on mower; Lawn riders which are small enough to fit through a garden gate and a perfect choice for small to medium sized lawns and garden tractors for larger lawns. Mountfield’s hand-held range of garden machinery includes grass trimmers and brush cutters, hedge trimmers, leaf blowers, and chainsaws. They are all designed to be lightweight and easy to use. They are suitable for both domestic and professional users.
Mountfield have recently released their Freedom 48 range of cordless garden machinery. Once you have purchased a battery and a charger, you can use them for any of the product in the range as they all use the same battery.
