NIGP 51556: Lawn Mowers, Riding Type (incl. Parts)

NIGP 51556 Lawn Mowers, Riding Type (Incl. Parts) is an Item code under which state and local governments procure new and used riding mowers—predominantly zero-turn and front-deck models with diesel or gas engines—for grounds maintenance across parks, correctional facilities, transit yards, airports, and municipal departments. Recent solicitations span equipment acquisition (new units at estimated values from $47,000 to $900,500), used equipment disposal, service and repair contracts with parts-discount structures, and comprehensive fleet management solutions. Issuing bodies include county boards of commissioners, cities, state departments of transportation and juvenile justice, water treatment utilities, college districts, correctional facilities, and airport authorities. The mix reflects grounds maintenance across infrastructure categories—correctional facilities, state parks, municipal fleets, and public universities represent standout repeat buyers within the recent activity.

Geographic spread covers Texas (multiple solicitations from TJJD, TxDOT, HHSC, and San Antonio), Florida (Hillsborough County, Collier County), Illinois (state parks procurement), Kansas (Wichita), Michigan (Jackson), Arizona (Tucson), Georgia (Department of Aviation), and a multistate cooperative (Sourcewell).
