The Ryan Lawnaire IV with Easy Steer Technology (EST) is a 19″ walk-behind aerator powered by a 4 HP Honda GX120 engine. Its 30 austemper-hardened steel tines deliver up to 2.75″ deep cores across a 3.75″ x 7″ pattern, covering up to 29,000 sq ft/hr. EST allows smooth turning without lifting tines, enhancing productivity and reducing turf damage. Removable weights and a compact design make it ideal for tight, landscaped areas.
