55 Series Gravity Wagons 455 • 555 • 655 • 755
Designed to Perform...Built to Last
Since J&M introduced their first gravity wagon in 1960, they have developed many patented designs and features that have provided farmers with better solutions transporting their grain from storage, to the field and back again… saving both time and money.
55 Series gravity wagons combine 60 years of design innovations. The wagons clean out exceptionally well because of the steepest back slopes (up to 33°) and end slopes (up to 42°)...even in high moisture grain. The 450 to 750 bushel capacity wagons feature a large 60" door with an oversized door wheel that is easily accessible from either side. Larger inspections windows allow greater visibility into the tank, while LED lights allow greater visibility while transporting.
Steeper Slopes
Excellent Cleanout
55 Series gravity wagons have the steepest back slopes (33° on 455/555 models and 32° on 655/755 models) and end slopes (42° on 455/555 models and 37° on 655/755 models) to ensure excellent cleanout, even in high moisture grain. We challenge you to check our measurements and our competitor’s measurements. You may be surprised to find out that others don’t stack up, despite what they publish.
Tight Turning Radius
Designed for maximum maneuverability, J&M's 55 Series gravity wagons feature a tight turning radius. The 455 and 555 models have a 6'-0" turning radius while 655 and 755 models have a 6'‑5" turning radius.

55 Series Gravity Wagons Options
Fender Kit
Fenders prevent splashing of mud and water onto the wagon to keep your wagon clean and looking good.
Hydraulic Drum Brakes
Optional factory-installed hydraulic drum brakes. The 16-ton running gear has a 2-wheel brake option available on the 455 and 555 models, while the 24-ton running gear on the 655 and 755 models uses a 4-wheel brake option.
Glide Right Roll Tarp
Smoother Tracking
Grooved rollers glide along the end caps for ultimate tracking, reducing the chances for misalignment.
Reduced Binding
Front and rear return springs apply even tension in front and back to reduce binding compared to systems that use a single return spring.
Patriotic Farmer Edition
To honor the patriotism of the American farmer, upgrade to the Patriotic Farmer Edition with an American flag decal. A portion of the proceeds generated from the American flag decal will be donated to national nonprofit organizations that provide assistance to farm families who have experienced a major injury, illness or disaster, or mobilize veterans to transition them from military service to farming.

Uni-Swivel Hydraulic Auger
The patented Uni-Swivel Hydraulic auger design allows the auger to swivel to any working position while maintaining a downwardly positioned discharge spout. The adjustable hopper can fit virtually any door size. Unique pulley and track stabilizer design allows the auger to stay in position and not pull to center.
