UNSPSC 21101522: Ridge plough or plow

A type of plow used for crops, such as potatoes or scallions, which are grown buried in ridges of soil using a technique called ridging or hilling. A ridging plough has two mouldboards facing away from each other, cutting a deep furrow on each pass, with high ridges either side. The same plough may be used to split the ridges to harvest the crop.

UNSPSC 21101522 Ridge plough or plow, a Commodity code, covers specialized tillage equipment that state and local governments purchase for land and wildlife management operations. The code encompasses heavy-duty, single-implement or multi-implement plowing and tilling tools designed for agricultural preparation, habitat management, and grounds maintenance. State and local issuing bodies soliciting under this code include natural resource and wildlife management departments at the state level, with individual purchases typically sized for single units or small fleet acquisitions rather than bulk contracts.

The Kentucky Department of Fish and Wildlife Resources and Illinois Department of Natural Resources dominate recent activity, each pursuing individual vertical tillage tools and disc harrows for wildlife habitat management. The Kentucky solicitation (RFB66027000001631, due October 22, 2026) requests a single 10-foot vertical tillage tool for Big Rivers Wildlife Management Area, with award on best value using a 100-point system weighing price (90 points), delivery time (5 points), and warranty period (5 points); Kentucky resident preference applies, and delivery to Sturgis, Kentucky is required. The Illinois Department of Natural Resources procurement (27422DNRRESCOB54373, due October 7, 2026) solicits a wheeled disc harrow funded through the Forest Stewardship Program Federal Assistance, requiring certified dealer status and compliance with federal regulations including Davis-Bacon Act and Build America Buy America Act. Both opportunities are limited-quantity, one-time purchases for specific facilities rather than recurring or multi-unit contracts. The code shows minimal recent activity; only two substantively relevant state and local opportunities are present in the current data, concentrated in Kentucky and Illinois.
