Attachment 1 - Salient Specifications (1 Page).docx

This is an Attachment containing salient specifications for two flail mowers required under solicitation 1240LP26Q0174, a Request for Quotations issued by the Department of Agriculture Forest Service. Both mowers must be compatible with John Deere 6145M tractors and capable of being towed and operated by these units. The 20-foot flail mower features a 600 cm (236") working width with hydraulically retracting wings that narrow to 240 cm (94") for road-legal transport. It must mulch grass and prunings up to 5 cm (2 inches) in diameter, require 80 to 150 HP, operate on a dedicated 1000 RPM rear PTO input with a standard 1 3/8" Z=6 input shaft, and be configured as a trailed triple-mower unit where the central unit can be uncoupled and operated independently. The mower is controlled from the tractor cabin via integrated solenoid valves and remote controls allowing independent wing lift and cutting height adjustment.

The smaller orchard flail mower features a slimline, low-profile chassis designed to operate under low-hanging tree lines without damage and must mulch grass and prunings up to 9 cm (3.5 inches), including heavy brushwood, wood chips, corn stubble, and tree branches. It requires 100 to 150 HP tractors and incorporates a powerful hydraulic side-shift mechanism allowing up to 70 cm (28") lateral movement to maintain safe distance from rows. The unit features a heavy 1000 RPM gearbox with internal freewheel mechanism and through-shaft, constructed from ultra-tough high-tensile steel with reinforced interior and replaceable internal wear plates for stone puncture protection. The smaller mower is a single-unit configuration measuring 300 cm (118"). Quotations are due September 18, 2026, at 1600 MT, with delivery required 60 calendar days after award. This is a Total Small Business Set-Aside under NAICS code 333111 with a 1,250-employee size standard.
