POWXG7512 is the perfect 2-in-1 electric scarifier for maintaining your lawn in a good condition. It’s equipped with a set of 10 knives to remove any thatch or moss build-up. The scarifier also has 18 needles that will allow air, water and nutrients to reach the roots of the grass. With the 320mm cutting width and central height adjustment in 5 positions you can easily set your machine to your own preference. You can detach the 30L collection bag for intensive demossing. Best time to start scarifying is in autumn before fertilizing or mid spring when grass starts to grow.
