All specifications on this page were taken directly from Bad Boy, the manufacturer. Figures from Bad Boy E-Magnum specs, checked November 2, 2026: Bad Boy E-Magnum specs. "Width (deck out)" is the OEM "Width (Chute Up / Chute Down)" figure given both ways. Electric; the OEM lists no engine, so battery system is shown. Top speed is 7 mph on the high setting.
Batteries instead of an engine
There's no engine on the E-Magnum. It runs on an 80V battery system with room for six batteries, rated at 8.0 Ah each. Four come with the mower. That means no gas can in the shed and no engine oil to change. With room for six batteries and four included, you can add the other two later.
You pick the pace with three speeds: 3 mph on low, 5 mph on medium and 7 mph on high. The deck's 1/8-inch, or 11-gauge, solid steel, fabricated. It cuts from 1.5 to 4.5 inches. Low is the setting to start on if you've never run a zero-turn before.
Where it fits
At 588 lb, it's a light zero-turn to move around the yard and in and out of the shed. With the deck out, it measures 48 inches wide with the chute up and 57 with it down. Measure your side gate against those numbers. If it clears, you can mow the backyard without a detour. Park it in the shed afterward, and there's no fuel smell to deal with.
It rides on 20x10-8 Reaper tires in back and 11x4.00-5 smooth tires up front, with an independent front suspension. It's a good fit for a yard with trees, beds and fence lines to work around. Low speed is handy close to the house, where you'd rather take it slow. If you'd rather stay with gas on a 42-inch deck, look at the MZ Rambler.
Battery mowers still wear out blades. When you need a new blade, bring the model number. The parts counter needs it to find the right part.
