DESCRIPTION

The MK Martin MKGW12000 Gravity Box is the largest capacity model in MK Martin’s legendary gravity wagon lineup engineered to move up to 1,200 bushels efficiently, safely, and with fewer trips. Built for demanding agricultural operations, the MKGW12000 is designed for high-volume grain and commodity handling, whether you're in harvest season or everyday transfer.

Constructed with heavy-duty 12-gauge steel and featuring dual 57" unloading doors for fast, smooth material flow, this industrial-grade grain box is supported by a robust 4"x8"x0.25" wall rectangular tubing frame. When paired with the 608 Horst Wagon running gear, it delivers unmatched durability and towing confidence on and off the field.

With operator-friendly touches like angled front ladders, sight windows, and road lights for transit safety, the MKGW12000 balances strength with thoughtful design. Optional upgrades including unloading augers, center dumps, and tarp kits further enhance its versatility, making this gravity box the powerhouse your grain operation deserves.
