Bad Boy 50 Series
The Bad Boy 50 Series is two compact utility tractors, the 5045 at 48 engine hp and the 5055 at 55 hp. Each comes as a ROPS or cab tractor, with a 16F/16R synchro or a four-range hydrostatic transmission. At J5 Tractors, our Bryan store sells the 50 Series, and it's our Bad Boy compact utility line.

All specifications on this page were taken directly from Bad Boy, the manufacturer. Figures from Bad Boy 5045 specifications and Bad Boy 5055 specifications, checked November 2, 2026: Bad Boy 5045 specifications, Bad Boy 5055 specifications. Bad Boy publishes two 3-point figures for the 50 Series: 3,306 lb at the link ends and 2,425 lb 24 inches behind them. The 24-inch figure is the one every other series on this site is measured by.
Where the 5045 and 5055 split
The two share nearly everything. Both run a four-cylinder, 139.5-cubic-inch engine and an 11.8-gallon tank. Both carry the BBL500 loader, which lifts 2,700 lb at full height and reaches 106.6 inches. They ride on the same 71.1-inch wheelbase with 15.5 inches of ground clearance.
Power is the split. The 5055 makes 55 hp and 44 PTO hp. The 5045 makes 48 hp and 38.4 PTO hp. If you'll run a wider cutter or other hard PTO work, that extra PTO power is the reason to step up.
Out back, the CAT I hitch lifts 2,425 lb, measured 24 inches back. Bad Boy also lists 3,306 lb at the link ends. At 64.9 inches wide and 127.4 inches long, it's a full compact utility frame. That's the size you want once the loader work gets heavy and the implements get wider.
Horsepower isn't the whole story, though. The 50 Series backs its numbers with a four-cylinder, more than 3,800 lb of weight and a 2,700 lb loader. Both models also have selectable four-wheel drive.
Synchro or hydrostatic, ROPS or cab
You've got four ways to build a 50 Series. The synchro models (S and CS) give you 16 forward and 16 reverse speeds, with 16.4 gpm of hydraulic flow. The hydrostatic models (H and CH) run four ranges and 15.7 gpm.
A hydrostatic changes speed and direction with a foot pedal, and that's handy on loader work. A synchro is a gear tractor. It suits long, steady passes behind a shredder.
The cab adds about 500 lb. A ROPS 5055 weighs 3,836 lb, and a cab tractor weighs 4,349 lb. A cab 5045 weighs the same 4,349 lb. Our cab season runs November through January, and August too. If you work through the cold months or the heat of August, a cab makes the long days easier.

Questions people ask
How do the Bad Boy 5045 and 5055 differ?
It's mostly power. The 5055 makes 55 hp and 44 PTO hp, and the 5045 makes 48 hp and 38.4 PTO hp. They share displacement, the loader, the wheelbase and the 3-point. Their weights land within a few pounds of each other, at 3,831 and 3,836 lb with a ROPS.
Why does the Bad Boy 50 Series have two 3-point lift ratings?
Bad Boy measures it two ways. At the link ends, the hitch lifts 3,306 lb. Measured 24 inches behind them, it lifts 2,425 lb. We use the 24-inch figure, since that's how the other series on our site are measured. Compare tractors on the same measure and you'll get a fair read.
Should I get the synchro or the hydrostatic Bad Boy 5055?
It comes down to the work. The hydrostatic (H and CH) runs four ranges and changes speed with a pedal, which suits loader work. The synchro (S and CS) gives you 16 forward and 16 reverse gears, with 16.4 gpm of flow to the HST's 15.7. If you'll spend long days behind a cutter, the synchro's worth a look.
How much does a Bad Boy 50 Series tractor cost?
