4/5-inch tier:Woodland Mills WC46 ($2,399, 4.5-inch, 2-year warranty) vs Woodmaxx MX-8500G+ ($2,695, 5-inch, 7-year warranty). The Woodmaxx costs $296 more but adds a half-inch of capacity and 5 extra years of warranty — a clear win for the MX-8500G+ unless you’re on a strict budget.
6-inch tier: Woodland Mills WC68 ($2,999, 5-year warranty) vs Woodmaxx MX-8600 ($3,195, 7-year warranty). This is the closest matchup. The WC68 is $196 cheaper; the MX-8600 has 2 years more warranty coverage. Both are self-feeding mechanical chippers for 20–65 HP tractors. The WC68 is one of the most popular PTO chippers in North America — proven, well-supported, and slightly cheaper. The MX-8600 is the pick if the 7-year warranty matters to you.
8-inch tier: Woodland Mills WC88 ($4,999, hydraulic feed, 5-year warranty) vs Woodmaxx WM-8H ($4,795, hydraulic feed, 3-year warranty) or Woodmaxx MX-8800 ($5,495, hydraulic feed, 7-year warranty). Three-way comparison: the WM-8H is the cheapest at $4,795 but has the shortest warranty (3 years). The WC88 splits the difference — $204 more than the WM-8H but 2 extra years of coverage. The MX-8800 is the premium pick: heaviest flywheel, 7-year warranty, $500 more than the WC88.
9-inch tier: Woodmaxx MX-9900 ($6,995, 7-year warranty) stands alone. Woodland Mills has no 9-inch model. If you regularly chip 8–9 inch material on a 40+ HP utility tractor, Woodmaxx is your only option in this category.
