The Westinghouse is the most powerful machine in this lineup, with a 15-amp motor, an 18-inch head and six sets of four integrated steel blades. At about 1,800 watts it outguns every battery tiller here, and unlike them it has no clock running on a battery. For a plot of a few hundred square feet it is simply the faster tool.
The cost is the cord. A 15-amp load wants a 14 AWG extension cord under 50 feet, or 12 AWG beyond, and you must manage the cable behind you so you do not run over it. Against the 12-inch 40V cordless it covers 50 percent more width per pass.
Its integrated blade assembly resists bending on buried stones, and it states up to 9 inches of depth, which in practice means two passes in firm soil. Store it dry, rinse the blades, and unplug it before clearing roots. If an outlet is within reach of your garden, this is the one to buy. At year three the likely wear points are the cord strain relief and the tine bolts, so look them over each spring.
