Key Features

MAxx-Gravity Model (MA20G and MA30G)

  • Available in 2,000 or 3,000 gallon (7,571 or 11,356 L) tank configurations
  • Material mix design is made to precise specifications at a central mix plant, resulting in no operator calculations and minor on-the-job adjustments to spreader box and water functions.
  • Premixed material loads directly into the tank and easily flows into the spreader box for application.
  • Full diameter sweep agitators keep the material homogenous and the aggregate in suspension.
  • Full-length ribbon mixer mixes the material and keeps it moving inside the tank which discourages segregation and separation.
  • Works with a standard Bergkamp spreader box; augers are optional
  • Requires a small crew with minimal training
  • Cleanup is quick and easy with a standard 300-gallon water tank and 25 ft hand hose

MAxx-Spray Model (MA20 and MA30)

  • Available in 2,000 or 3,000 gallon (7,571 or 11,356 L) tank configurations
  • Accurate application rates at variable speeds
  • High-accuracy spray system that reduces the need to “cut-in” along curbs
  • Clog-free nozzles eliminate plungers and rear operators
  • Low-pressure system – under 50 psi
  • Computer controlled calibration and application
  • Smooth starts and stops without puddles of excess material
  • Full sweep ribbon mixer with counter-flow mixing technology keeps aggregate in suspension
  • Ribbon mixer is operable during transit, pumping and spraying operations
  • Quick clean up with standard water tank and high-pressure power washer
  • Computer control system allows all systems to be operated from inside the cab
  • Patented Spray System improves accuracy and clog-free spray nozzles reduce downtime and eliminate the need for a rear operator
  • The unit is powered by a PTO-driven hydraulic pump that delivers plenty of power to operate all systems simultaneously

Both MAxx models are available for purchase through these cooperative organizations.

Optional Equipment

  • Night vision backup camera with sound
  • (MAxx-Spray Only) Second material pump decreases loading time and increases application speed
  • (MAxx-Spray Only) Laser level sensor estimates the level of material in the tank so the operators know when to stop and refill. The sensor only detects the level, and it is not an accurate measurement of materials used.
