The Agri-Fab 45-0458 SmartLINK Turf Shark Curved Blade Aerator is a patented design combining the best features of a plug aerator and a spike aerator. The turf shark spike wheels provide the perfect amount of penetration and soil plug removal without the mess associated with plug aerators. The curved blade aerator cuts slits into the ground to a considerable depth but then claws out slivers of earth allowing access for fertiliser, seed, water and air. The scattered earth is much less obstrusive than when you use a plug-type aerator. If your lawn or playing area is particularly compacted or consists of hard soils like clay, removal of earth allows it room to loosen up. This unit has a 42/107cm working width with 10 galvanised blades for rustproof durability. The Agri-Fab SmartLINK Turf Shark Curved Blade Aerator can be attached to the SmartLINK Master Platform in seconds.
