All specifications on this page were taken directly from Bad Boy, the manufacturer. Figures from Bad Boy ZT Avenger specs, checked November 2, 2026: Bad Boy ZT Avenger specs. "Width (deck out)" is the OEM "Width (Chute Up / Chute Down)" figure given both ways.
The 54 or the 60
Both decks come with the Rehlko Pro 7000 KT726 at 26 hp or the Kawasaki FR691V at 23 hp. The 60-inch adds the Kawasaki FR730V 25th Anniversary Edition at 24 hp. Power goes through a Hydro-Gear 2800 10cc integrated transaxle, and top speed is 7 mph.
Which engine fits you? The Rehlko has the most power at 26 hp. The Kawasaki FR691V is the 23 hp option. The Anniversary Edition on the 60 sits between them at 24 hp.
There's not much weight between them: 746 lb for the 54 and 763 lb for the 60. Both cut from 1.5 to 4.5 inches on a 7-gauge solid steel deck. Tires match too, 12x6-6 smooth up front and 20x10-8 Reapers in back. The real difference is width.
Sizing it to your yard
The ZT Avenger is a homeowner's mower for a wide lawn. A 54 or 60-inch deck takes a big bite on each pass, so open yards go faster. With the chute up, the 54 measures 58 inches wide and the 60 measures 64. Chute down, they're 67 and 73.
That can be wider than a garden gate. Measure yours, and your shed door, before you settle on a deck. The tank holds 6 gallons. Coming off a push mower? Give yourself a few passes in open grass to get used to the levers before you work near beds. Need a 48-inch deck instead? Look at the ZT Elite.
Keep an eye on the air filter through the summer. It's the maintenance owners skip most, and it's a small part that protects the engine. A dusty yard clogs one sooner.

Questions people ask
Which Bad Boy ZT Avenger comes with the 25th Anniversary Edition engine?

How heavy is the Bad Boy ZT Avenger?
The 54-inch model weighs 746 lb and the 60-inch weighs 763 lb. Both ride on 20x10-8 Reaper tires in back and 12x6-6 smooth tires up front. If you're moving it on a trailer, check the trailer's rating before you load up.
How low and how high does a Bad Boy ZT Avenger cut?
It cuts from 1.5 to 4.5 inches on both the 54 and 60-inch decks. The deck's 7-gauge solid steel. That range covers a short cut in spring and a taller one when you'd rather leave the grass long through a dry summer.
