78" Farm-Maxx Disc Harrow - DH42018 NSB
DH2018 NSB
Farm-Maxx DH42018 Disc Harrow (20 Blade, 18") — NSB
The Farm-Maxx DH42018 is a 20-blade disc harrow with 18-inch notched blades across a 6½-foot working width — a versatile mid-range harrow built for tractors from 35 to 55 HP. It sits in the DH-400 series, which means you get a reinforced 2×3" tubular steel frame, a fully adjustable slide-gang system, and sealed ball bearings, all in a package that weighs around 725 lbs. Whether you're breaking up a fallow field for spring planting, incorporating cover crop residue, turning under garden waste, or prepping food plots, this harrow has enough blade count and width to get it done in fewer passes without needing a big utility tractor to pull it.
Features
-
20 Notched Disc Blades (18" Diameter)
High-carbon steel notched blades at 3.5mm thickness bite into compacted soil, sod, and crop residue. Notched edges are more aggressive than smooth blades, cutting through root mass and tough ground cover. -
6½-Foot Working Width
Covers ground quickly on pastures and food plots while still fitting through standard farm gates. -
7½" Blade Spacing
Tight spacing ensures thorough soil mixing with no untilled strips — important for seedbed prep where you need a consistent, lump-free finish. -
Fully Adjustable Slide-Gang System
Front and rear gangs slide independently to set cutting angle. Steeper for aggressive first-pass breakup, flatter for finishing and leveling. Adjusts without tools. -
2×3" Tubular Steel Frame
Heavy-wall rectangular tubing provides solid frame rigidity without excessive weight. Strong enough for demanding conditions, light enough for compact and mid-size tractors. -
1" Square Axle Shafts
Forged and swaged one-inch square axles resist bending and flexing under load, even in hard-packed or rocky ground. -
Sealed Ball Bearings
Factory-sealed bearings keep out dirt and moisture for extended service life and low maintenance. -
Category I/II 3-Point Hitch
Compatible with both Cat I compact tractors and Cat II utility tractors. Quick-hitch compatible for easy hookup.
