Computer Balanced Auger

Super-Edge Flighting Balanced to Within One Ounce
All J&M grain carts feature thick flighting with a patented Super-Edge that puts more material where it is needed, on the outer edge. In addition, we reinforce the flighting at critical wear points to increase life and durability.

All augers are balanced to within ONE Ounce. Precision manufacturing ensures a quiet running system that extends overall auger life and performance by reducing vibration to the drive system.

Balanced Tongue Weight

The weight distribution of J&M grain carts are superb compared to competitive carts. The undercarriage axle is positioned to produce a properly balanced tongue weight, reducing the stress and upgrade costs on your tractor draw bar.

V-Truss Axle

Added Strength Prevents Twisting or Bending

Competitor grain cart axles feature small tubular steel that is prone to bending or I-beam designs that are prone to twisting, which puts premature stress on the rest of the cart. J&M’s exclusive V-Truss axles are engineered using heavy-duty tubular steel with a reinforced V-Truss design to resist both bending and twisting, protecting the cart from premature wear and tear. Standard on all single wheel carts.
