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.

Sleeved Spindles

1Sleeved Spindles

For maximum strength, spindles are inserted into heat-shrunk sleeves for welding.

2Oil Bath Hubs

Synthetic oil provides superior bearing protection and excellent lubricant flow, even in the coldest weather.

3Tie-Rods

Tie-Rods with clevis ends and replaceable bronze bushings make for easy maintenance.

55 Series Gravity Wagon Options

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.

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.

Fenders

Fenders prevent splashing of mud and water onto the wagon to keep your wagon clean and looking good.
