The Earthquake Walk-Behind Edger is an incredibly versatile tool for homeowners and landscapers alike to achieve beautiful and professional looking borders around lawns, sidewalks, driveways and property lines. The 79cc Viper engine spins the tri-tip steel blade at 3400 RPMs to make quick precision cuts that will leave crisp, clean lines. The multi-angle cutting head offers 5 positions from 70 to 110 degrees to ensure that you have the correct angle available to conquer all grass types. In addition to edging, this unit doubles as a small utility trenching tool for backyard cables and wires. Backed by a 5-year limited warranty.
