Scraper-Drawn Water Tanks

Genuine Mega Design for Scraper-Drawn
Water Tanks (MSC or MST)

Mega manufactures a complete line of water tanks for Caterpillar® or Kress wheel tractor scrapers. Our scraper drawn water tanks can be built for either rigid hitch or drop tank configurations. These are available for dealer installation or with Mega factory installation. Every tank includes a complete set of technical manuals detailing installation, operation, maintenance, inspection and replacement parts. Mega tanks are constructed with premium materials and are inspected throughout the manufacturing process to produce the best water tanks and spray systems available.

Mega can convert your scraper to a water tank or replace an existing water tank. The gooseneck, draft frame and wheel and brake group may be re-used or replaced with new Mega components.

Mega scraper water distribution systems can be purchased for integration with a dealer-provided tractor (MSC) or as a complete solution with a Mega-provided tractor (MST). Purchasing your complete solution directly from Mega streamlines the ordering process and significantly reduces the complexities related to delivery timing and shipping.

Models are available for drop and rigid hitch types. Please contact our Mega Sales Team regarding shipping information and models not listed.
