Model 3W6 - Sprayer



The 3W6 buggy is a great option for light weight high flotation applications for both spreading and spraying. It offers a three wheel stance to provide staggered tire track spacing – limiting ground pressure and compaction. This buggy is more maneuverable and adaptable than other buggy’s on the market today.

  • The 3W6 is adaptable and interchangeable for both spraying and spreading with liquid or dry application systems.
  • The 3W6 is a very low maintenance machine requiring very little cost to maintain and operate.

The buggy is powered by a 6-cylinder 173 horse powered Cummins diesel engine which provides 590 ft-lbs of torque. It’s delivered through an Allison 4-speed automatic transmission, driven by a JCB rear end that has an outboard planetary, single speed with internal wet brakes. The main frame chassis features a wheel base of 15’ 6” and offers an 6,000 lb. payload capacity. It has a dry weight of 11,000 lbs and can be configured with both tundra flotation or row crop tires.

This versatile machine spray system is configured with a 600 gallon stainless steel tank with mechanical agitation, 60’ 70’ or 80’ stainless booms and a centrifugal or diaphragm pump. Spreading systems can be configured with either a 2 or 3 ton stainless dry box with double spinners.
