Argo Water Tank Trailer: Ready For Operation

Water Trailers For Sale
Flexibility in the field is important. Watch how we've designed the most efficient buffalo trailer for hauling water. We've equipped each buffalo tank water trailer with discharge ports, including:

  • Spray Nozzles for Wide Coverage. The galvanized spray bar covers a maximum swath of 25 feet. Common uses of this water sprayer trailer include controlling dust on roads or job sites, compacting roads, and irrigation.

  • Fire Hose for Targeted Coverage. All water buffalo trailers include a 25-foot fire hose that couples to the fire hose valve on either side of the trailer. (Also available in 50 or 75' hose lengths.)

  • Discharge Options. A hose bibb is located on the discharge manifold for uses such as washing equipment and other low volume applications.

For more details on these and other accessories, visit the Water Tank Trailer Accessories page.

Argo Mobile Water Trailer Features

water trailer specifications

  • Easy to Use Water Fill-Up Options. The Argo water trailer can be filled with any of these three options:
    1) fill the tank manually,
    2) draw water through the quick-fill fitting, or
    3) draw water through the pump.

  • Powered Fill-Up and Pumping. A 4 horsepower Honda engine drives the pump and can be used for quick fill up of the water buffalo tank or for powering the discharge of water.

  • Convenient Storage Provided. Each Argo Water Tank Trailer comes with a lockable tool box mounted to the deck of the trailer. Store hoses, tools, or accessories in a convenient location.

  • Instructions Permanently Attached. No need for your operators to search for instructions. We've mounted the valve control instructions right on the front deck of the Argo Water Trailer.
