About this file
This is a technical specifications document for a compact utility tractor with integrated attachments. The government is seeking delivery of one new compact utility tractor equipped with a hydrostatic transmission (HST), front loader with 66-inch bucket, and factory-mounted subframe backhoe attachment. All equipment must meet or exceed the specified salient characteristics, with brand names used only to define minimum requirements; equal products are acceptable.
The tractor must feature a diesel engine with approximately 24.8 gross horsepower, three-cylinder liquid-cooled design, operating at 2,200 rpm, and compatible with standard off-road diesel fuel. The HST 3-range transmission shall include independent rear PTO at 540 rpm with safety lockout features and approximately 19 HP PTO horsepower. Additional tractor specifications include an open-center hydraulic system (5.0–5.2 gpm implement flow and 3.0–3.2 gpm steering flow), Category I three-point hitch with 1,800–1,900 lb lift capacity, four-wheel drive chassis weighing approximately 2,600–2,800 lb with foldable ROPS, R4 industrial or R1 agricultural tires, and a 12-volt electrical system with 40-amp alternator. The front loader (equivalent to LA526) must provide maximum lift height of approximately 94–95 inches with 1,050–1,100 lb capacity at full height and include quick-detach bucket functionality. The backhoe attachment (equivalent to BH77) must be subframe-mounted with approximately 93–94 inches digging depth, 3,300–3,450 lb bucket digging force, 2,100–2,250 lb dipperstick force, 180-degree swing and rotation capabilities, and transport height of 80 inches. Delivery shall include full assembly, service, complete documentation (operator, service, and parts manuals in digital or print format), standard manufacturer warranty, and up to two hours of operator familiarization training.
