Now that spring has arrived, it’s the perfect time to get your lawn into shape for the new gardening season. We’ve teamed up with garden machinery specialist Cobra to give BBC Gardeners’ World Magazine subscribers the chance to win a cordless rear-roller lawnmower. With seven cutting heights you can keep your grass looking its best all year round. Powered by a 40V lithium-ion battery, it’s powerful but lightweight, has a long running time, and eliminates the need for petrol and cables, too.
