Large Capacity Gravity Wagons

Models 455, 555, 655 and 755

Better By Design

Models 455 • 555 • 655 • 755 Gravity Wagons

The new 55 Series Gravity Wagons feature a sump tank design with steeper end

slopes (up to 42 degrees) and back slopes (up to 33 degrees) for maximum cleanout,

even in higher moisture grains.

 

The extra wide 60” door provides fast unloading, while the oversized door wheel

with heavy-duty gear reduction door opener makes opening and closing effortless

and easily accessible from either side of the door. Extra large inspection windows

provide maximum visibility into the tank while the deluxe LED lights provide

maximum visibility during road transport.

 

Designed with oversized sleeved spindles and oil-bath hubs, the 16 Ton Running Gear

and the 24 Ton Running Gear with cushion tongue, dual lift spring and optional hydraulic

drum brakes ensure maximum performance. Rubber mounted absorbers between the box

and gear reduce noise during transport, while the pull-through rear tongue protects the

wagon from wear and tear while towing multiple units at a time.

 

55 Series Features

• 655 or 755 bushel capacity with 24 ton running gear with “cushion” tongue and four-wheel drum brakes.
• 455 or 555 bushel capacity with 16 ton running gear with “cushion” tongue and two-wheel drum brakes.
• Dual compartments available.
• Sharp turning radius forgreater mobility.
• Patented side discharge chute adjusts from 14” to 19” tall unloading height in seconds without tools.
• Heavy-duty 3” (16 ton) or 3 3/8” (24 ton) diameter sleeved spindles provide maximum strength and durability.
• Pull through extended rear hitch eliminates stress on the rear axle during tandem towing. Rear 7-prong
connector receptacle provided for easy hook-up.
• Heavy-duty 12 ga. & 9ga. tank and side construction.
• Tank sump design provides complete cleanout…even in high moisture grain.
• Steep end slopes and wide door for faster unloading.
• Standard heavy-duty gear reduction door opener for effortless opening, even when the box is completely full!
• New style rocking bolster increases stability, yet provides flexibility in rough terrain. Rubber cushion
pads between gravity box and running gear reduces noisy “chatter” during empty transport.
• Tie rods are positioned behind the axle for greater protection. Front wheels have an automotive tow
setting for true-tracking.
• Bronze bushings are located at steering wear points for easy and inexpensive maintenance.
• A high-intensity lamp near door is included.

 

Available Options

Small Capacity Gravity Wagons

A common misconception is that all wagons are designed the same. Therefore, it is

assumed that the wagon with the greatest amount of back slope will clean out better.

This is not necessarily true. Some competitor wagons rely solely on steep slopes

and gravity for unloading. With their design, the angle of slope becomes critical for

complete cleanout, especially in higher moisture grains. With these designs, an extra

degree of slope could make all the difference. We take the design of the tank one

step further. Not only are our wagons engineered with a steep back slope, but we

also utilize a Sump Design to maximize cleanout. The sump design “pulls” grain

into the unloading chute. Not All Wagons Utilize This Feature! This is why J&M

gravity wagons have built an excellent reputation for complete cleanout even in

high moisture grains!

Patented Uni-Swivel Hydraulic Augers

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.

• 6” Diameter x 15’ long auger system

• Steel or poly-cup plastic interior flighting

• Adjustable hopper wings can fit a range of door opening widths

• Screw-cap fitting at bottom of auger tube for easy cleanout

• Optional 3-Stage Telescoping Spout

 

Portable AugerMate Power Unit

• Eliminates the need for a tractor

• 8 Horsepower engine with optional electric start

• Direct mounted hydraulic pump, eliminating belts, pulleys and chance of misalignment

• Oversized 5 gallon oil reservoir

• Mounting frame included for easy attachment to the gravity box
