The Westinghouse pairs a 15-amp motor with an 18-inch head carrying six sets of four integrated steel blades on an 8-inch diameter rotor. A 15-amp motor is about 1,800 watts, the most a standard household circuit can deliver, and tine speed reaches about 400 RPM, slightly faster than the 360 to 380 RPM of rivals.
The integrated blade design means the tines are part of a single assembly rather than loose bolt-on pieces, which resists bending on buried stones and avoids loose hardware. It lists a stated depth of up to 9 inches, which in practice means 5 to 6 inches on a first pass in firm soil, deeper on a second.
Compared with the 13.5-amp LawnMaster it has one and a half more amps of reserve, which shows in compacted soil. The trade is that it does not advertise a stall-protection clutch, so a stuck tine can burn the motor if you lean on it. Use a 14 AWG cord under 50 feet and keep it behind you. Rinse and dry the blades after each session. At year three, the usual wear points are the cord strain relief and the tine bolts, both easy to inspect before each season.
