Single Auger VS Dual Auger Grain Carts

Ultimately, it comes down to preference, but there are differences in how these grain carts run and operate. A single auger cart is gravity fed, which is why these carts are usually more box-shaped. There needs to be enough slope for gravity to take all of the grain down to where the vertical auger funnels it out. This is also why single auger grain carts max out at 1500 bushels.

 While a dual auger cart has a vertical auger that lifts the grain out of the cart, it also has a horizontal auger on the bottom of the cart. This auger brings the grain to the front of the cart, where the previously mentioned vertical auger can lift the grain out into a wagon or grain trailer. Thus, dual auger carts can have a much lower profile in terms of overall height. 

 But, with the horizontal auger on a dual auger cart comes more maintenance and moving parts: more that can go wrong. Some guys prefer a single auger cart simply due to the simplicity. But, dual auger carts unload faster due to the vertical auger being 2 inches larger in diameter, as well as having a bottom floor auger, speeding up the process of transferring the grain to the vertical auger versus single auger carts simply relying on gravity. This speed difference when unloading becomes even more apparent for heavier moisture crops, particularly corn.

Another factor to consider with dual auger grain carts is the center of gravity. The lower center of gravity gives more clearance for the combine auger, which is also important for those who operate on hilly terrain.
