Dual and Triple Wheels Unverferth Wheel Products

As the advantages of agricultural dual wheels became more evident, farmers sought a more permanent mounting soultion for year-round use. Unverferth direct-axle duals and triple wheel packages fill this need using a bolt-on spacer or hub and factory-style wheels for maximum versatility.  These agrictultural wheel systems provide greater pulling power and increased flotation for tractors, combines, self-propelled sprayers and other equipment.

The T-Rail® system is more than just a quick conversion to the added power and efficiency of dual wheels. It also gives you the strength, durability and precise alignment of semi-permanent duals, even on the biggest equipment. The key is the clamp and rail assemblies which hold the dual in place for optimum performance.

Regardless of your crop tillage practices, look to Unverferth for the extensions you need to center your wheels down the middle of the row. From dual and triple axle spacers, to MFWD hub extensions, your Unverferth dealer can put you and your wheels on track.
