Grain Cart Main Image
Grain Cart

New from your trusted harvest partner come the MK Martin Grain Carts. Available in a range of 650 - 1,050 bushel models, these Grain Carts are ready to take the field when you are.

A hydraulic shield covers the auger when not in operation allowing the auger to start empty. Not only does this save the drive system, it also gives you, the operator, full control over metering the unloading speed.

Featuring an unload time of 2 minutes and utilizing the hydraulic shield to retrieve the lost grain along with a clean-out hatch, not only can you quickly and easily unload the contents of your Grain Cart, but you can ensure you limit the amount of wasted grain - meaning more profit for you and your business.

Auger Feature Image


The hydraulic front folding auger design increases operator visibility, provides more reach, and requires less repositioning during the unloading process. The chute is equipped with a hydraulic hood to better control the placement of your grain.

Driven by your tractor's PTO, the auger quickly and effortlessly empties the hopper. A hydraulic shield covers the auger when not in operation and helps to contain the lost grain transferring them up the auger.

Exclusive to the 1050 model, the auger is located on the right side allowing the operator to have both the auger and controls on the same side making it more operator friendly.

Hopper Feature Image


All sides of the hopper angle toward the auger's sump, ensuring virtually all grain is picked up and transferred through the auger.

For operator safety and equipment protection, a wire mesh grating keeps unwanted objects from entering the auger during operation.
