Why Add an Electronic Scale System?

Comparison of 3 Point Grain Cart Scale vs 5 Point Grain Cart Scale

Adding a scale system to your grain cart will increase your harvesting efficiency and record keeping accuracy. Depending on the size of the cart, J&M currently offers a 3 point or 5 point scale system. All scales are factory installed and calibrated to be accurate within 0.5% on a 5 point system and 1.0% on a 3 point system on grain carts using tires up to 31" wide. An upgraded indicator will automatically log the unloads for simpler record keeping, and with smart options like moisture and auto gate shut off, the operator can focus on harvest. Exporting records is as simple as an email or inserting a USB drive. With the iFarm Plus, your records can be sent directly to the cloud for the farm manager with no user input. Choose any of our indicators from economically priced to feature rich depending on your farming needs.

3 point systems place the weigh bars in the spindles. This placement is fine for tires up to 31" wide, but as grain cart tires get wider than 31” the distance from the center of gravity increases, causing the torque being applied to the weigh bars to increase exponentially when the cart is on an angle. This causes the 3 point scale system to become inaccurate. J&M was the first in the industry to use a 5 point scale system when using these wide tires. The 5 point system places 4 weigh bars in the axle, so the weight is distributed on the weigh bars evenly to keep the scale system accurate within 0.5%.
