About this file
This document contains detailed technical specifications for a disk harrow required by the Mingo National Wildlife Refuge under solicitation 140FS225Q0045 from the U.S. Fish and Wildlife Service.
The specifications outline requirements for a heavy-duty agricultural disk harrow with 250-325 HP engine power, 25 ft 2 in tillage width, and hydraulic controls for wing fold, depth, and fore-aft leveling. Key components include 72 blades at 9-inch spacing, with 24-inch diameter working blades and step-down blades ranging from 22 to 20 inches. The machine features a robust frame construction with 6x6 inch and 4x4 inch tubes, gang angles set at 18 degrees front and rear, and heavy-duty spring steel scrapers. The transport configuration measures 14 ft 6 in width by 12 ft 6 in height, with walking tandem 8-bolt 340-55-16 stubble resistant wheels on both mainframe and wing frame. The system requires 2,400 PSI minimum hydraulic pressure and a 12-volt electrical system with 7-pin connector.
