Where a rotary tiller spins blades to chop soil into a fine seedbed (best for already-broken ground), the disc harrow uses angled spinning discs to slice through sod, mix surface organic matter into the soil, and create the rough cuts that primary tillage requires before secondary finishing.\u003c\/p\u003e\u003cp\u003eThe 48-inch working width clears roughly half an acre per hour at typical tow speeds, with two angled gangs of eight discs each providing aggressive ground penetration without requiring excessive tow horsepower. The disc count is the design specification that determines coverage uniformity: 16 total discs at 4-inch spacing across the 48-inch frame produce continuous cutting with no untouched strips between disc paths.\u003c\/p\u003e\u003cp\u003eThe discs themselves are 16-inch diameter notched steel — the standard for serious tillage equipment. The 16-inch diameter delivers meaningful penetration depth without requiring excessive weight; the notched edge is the engineering improvement over plain-edge discs, gripping into established sod and woody surface roots rather than skipping across them. Heat-treated steel maintains the cutting edge through years of regular use.\u003c\/p\u003e\u003cp\u003eThe two gangs are independently angle-adjustable. Increasing the gang angle (the angle between the disc gang's rotation axis and the direction of travel) increases ground penetration depth and aggression — the right setting for breaking new ground, primary tillage, and aggressive sod-cutting. Decreasing the gang angle reduces penetration depth and produces a smoother finish — the right setting for secondary tillage, leveling already-worked ground, and surface seedbed preparation.\u003c\/p\u003e\u003cp\u003eA concrete-block weight tray sits between the gangs, allowing the operator to load standard concrete blocks (sold separately, available at any home improvement store for under $5) for additional ground penetration on hard-packed or root-bound ground. Empty, the harrow weighs approximately 175 pounds. With four standard blocks in the tray, the unit reaches roughly 335 pounds — sufficient for most residential and food-plot applications.\u003c\/p\u003e\u003cp\u003eThe frame is welded heavy tubular steel with corrosion-resistant powder-coat throughout. Sealed maintenance-free bearings on each disc spindle eliminate the routine greasing required by older grease-fitting designs. The hitch is a universal pin design that fits most lawn tractors, riding mowers, ATVs, UTVs, and sub-compact tractors with sufficient drawbar strength to pull the loaded weight through aggressive ground engagement.\u003c\/p\u003e\u003cp\u003eFor owners managing food plots, hunting plots, vegetable production, or pasture renovation, the disc harrow is the primary-tillage tool that turns a contractor visit into self-service capability.\u003c\/p\u003e","brand":"Agri-fab","offers":[{"title":"Default Title","offer_id":42771594051678,"sku":null,"price":539.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1159\/9138\/files\/61Y7VPdEHML._AC_SL1500.jpg?v=1778943745","url":"https:\/\/sparroo.shop\/products\/4-ft-tow-behind-disc-harrow-16-notched-discs","provider":"Sparroo","version":"1.0","type":"link"}
