6-inch PTO chipper and one of the most popular 30–40 HP tractor chippers in North America.
Woodland Mills WC68 Wood Chipper Full Product Walkaround (2024)
Official walkaround of the WC68 showing the 23" x 27" infeed hopper, direct-drive flywheel, and adjustable feed roller system.
- 5-year warranty
- Heavy flywheel for its class
- Strong reputation among compact tractor owners
- Mechanical feed — no hydraulic option
- 6-inch ceiling
Why the WC68 punches above its weight
The WC68's flywheel is noticeably heavier than competing mechanical-feed PTO chippers in the 6-inch tier. Flywheel mass translates directly to sustained feed rate on hardwood — once the flywheel is up to speed, it doesn't slow down when you feed thicker material. This is the single reason the WC68 has the reputation it does.
The 5-year warranty is also best-in-class for mechanical-feed PTO chippers. Competing Woodmaxx MX-Series chippers match it at 7 years; the WM-Series is shorter at 3.
Where the WC68 loses to the competition
No hydraulic feed. If you regularly chip forked, crooked, or limby wood, the WC68 will hang up where a hydraulic-feed chipper (Woodmaxx WM-8H, MX-8800, or Woodland Mills' own WC88) would pull the material through. For clean wood up to 6 inches the WC68 is superb; for messy brush it's average.

“Fits” = within the manufacturer’s rated PTO HP range. “At limit” = below the minimum by 5–15%, will feel underpowered on seasoned hardwood. “Too small” = undersized for reliable chipping. “Oversized” = above range (works but overkill).
Who should buy the WC68 — and who should skip it
- You own a tractor with 20–65 PTO HP and a Category 1 or 2 three-point hitch.
- Your typical branches are 4–6 inches in diameter.
- You chip mostly straight material and want the simpler, more reliable self-feeding mechanism (fewer hydraulic components to service).
- You plan to keep the chipper 5+ years and value the 5-year warranty.
- You want a capable chipper under $3k without stepping up to commercial-grade pricing.
- You don't own a tractor. A gas-standalone chipper of comparable capacity is the right category for you.
- You regularly chip forked or crooked wood. Mechanical feed hangs up on these; consider a hydraulic-feed chipper in the same capacity tier.
WC68blade replacement & sharpening
Four flywheel knives on the WC68 — a defining spec versus the 2-knife competitors in this size class, and the reason chip quality holds up on 6-inch hardwood.
All four knives must be sharpened to the same dimension to keep the heavy flywheel balanced — mark them 1–4 at removal.
Woodland Mills publishes the exact blade-to-anvil gap (~0.030") in the WC68 manual; set it with a feeler gauge on reinstall.

- 01Stop the machine and isolate power
Disengage the PTO, shut the tractor off, and remove the key. Wait 60+ seconds for the WC68 flywheel to stop completely — it coasts longer than the engine.
- 02Open the discharge or flywheel access cover
Remove the bolts on the WC68 flywheel access hood (or flip the hinged hood if equipped). Swing it clear so you have line-of-sight to every blade position.
- 03Rotate the flywheel to the first blade
Turn the flywheel by hand until the first of the 4 knives is aligned with the access opening. Mark it "1" with a paint pen so you can keep track of orientation.
- 04Break the blade bolts loose
Use a breaker bar on each of the 2 blade bolts. Woodmaxx and Woodland Mills both thread-lock these at the factory; heat gently if they don't yield. Do not pry on the flywheel itself.
- 05Slide the blade out and inspect
Remove the blade and inspect for cracks, nicks deeper than 1/16", and rounded bevels. A cracked blade goes straight in the scrap bin — never re-sharpened.
- 06Flip or replace the blade
The WC68 uses 4 reversible knives. If the secondary edge is still clean, simply flip the blade for a fresh edge. If both edges are worn, sharpen at 30–35° on a belt sander — quench every 10–15 seconds to avoid bluing the Hardened tool steel.
- 07Balance the set
Remove equal material from every blade in the set. On the WC68's 4-knife flywheel, even a 1–2 gram imbalance shows up as vibration at operating RPM. Weigh on a gram scale after sharpening.
- 08Reinstall and torque
Apply anti-seize to the bolt threads (not the heads) and torque in a star pattern to 50–60 ft-lb. Use fresh lock washers — reused washers are the #1 cause of a loose blade downstream.
- 09Repeat for every remaining blade
Rotate the flywheel and repeat steps 3–8 for the remaining 3 knives. Then inspect the fixed bed knife — if the edge is rounded, flip or replace it and reset the blade-to-anvil gap to ~0.030" with feeler gauges.
- 10Close up and test-run
Rotate the flywheel by hand one full revolution to confirm no contact with the bed knife or housing. Close the access cover. Start the tractor, engage PTO at low idle, and listen for 30 seconds before ramping to operating RPM. Feed one small test branch before returning to normal work.
Real owners on the WC68
- Heavy flywheel punches above its HP class. The WC68 flywheel is the most-cited strength — owners on 25–30 HP compacts report it chips 5–6 inch hardwood with authority.
- Mechanical feed is a love-it-or-leave-it. No hydraulic rollers. Fans say it is simple and unbreakable; detractors wish for powered feed on thicker stock.
- Fit and finish is above the price point. Paint, welds, bearing covers and instructions are repeatedly called genuinely good — not cost-cut.
“My 26 HP Kubota does not flinch. The WC68 flywheel carries so much momentum that the tractor is almost coasting through 5-inch maple.”
“No hydraulics means nothing to leak, nothing to adjust, nothing to rebuild in ten years. That simplicity is exactly why I bought it.”
“Unboxed and the paint, welds and manual are all a tier above what I expected for three grand. Woodland Mills seems to actually care.”
“Four years, four cords of firewood brush per year, zero issues. Replaced the blades once. Best tractor implement I have ever bought.”

WC68 — frequently asked questions
- Is the Woodland Mills WC68 worth it?
- Yes — for 30–40 HP compact tractor owners chipping mostly straight material under 6 inches, it's the best value in the category. The 5-year warranty and heavy flywheel give it an edge over similarly-priced mechanical-feed chippers.
- WC68 vs Woodmaxx MX-8600 — which should I buy?
- WC68 is ~$200 cheaper and has a 5-year warranty. MX-8600 has a 7-year warranty and Woodmaxx's typically-faster parts availability from NY. Capacity and feed are the same (6-inch mechanical self-feed). Either is a defensible pick; we slightly favor the WC68 for the lower price and heavy flywheel reputation.
- What size tractor do I need for the WC68?
- 20–65 HP tractor. The sweet spot is 30–40 HP. On 20 HP subcompacts you'll feel the HP limit on 6-inch hardwood; on 40+ HP tractors you're comfortably above the minimum.
- Does the WC68 have hydraulic feed?
- No. The WC68 is mechanical (gravity) self-feeding. For hydraulic feed in the Woodland Mills line, step up to the WC88.
- How much tractor HP do I need for the WC68?
- The Woodland Mills WC68 6-inch PTO Woodchipper is rated for 20–65 PTO HP. That's tractor PTO horsepower after drivetrain losses — rated engine HP is typically 10–15% higher. A 23 HP engine tractor produces roughly 20 PTO HP and would run this chipper at the minimum. The comfortable working range is 25–59 PTO HP.
- Does the WC68 fit a Category 1 three-point hitch?
- Yes. The WC68 mounts to a standard Category 1 or 2 three-point hitch and accepts a 540 RPM rear PTO shaft (included). Quick hitch compatibility varies by brand — most John Deere iMatch and Pat's Easy Change hitches accept it with a standard top-link bushing.
- What's the maximum branch diameter the WC68 can chip?
- The Woodland Mills WC68 6-inch PTO Woodchipper is rated for branches up to 6 inches in diameter. Green and softwood branches chip reliably at the rated maximum. Seasoned hardwood at the maximum slows the feed rate and bogs the flywheel more — plan for 5-inch hardwood as your comfortable working size.
- What's the warranty on the WC68?
- Woodland Mills covers the WC68 with a 5-year warranty. It covers manufacturing defects but excludes wearing parts (blades, belts, bearings under normal wear) and cosmetic damage.
- Is the WC68 self-feeding?
- Yes — the WC68 uses a gravity + mechanical self-feeding design. Infeed rollers are driven by the flywheel. Works well on clean straight branches; forked or crooked material can hang up on the rollers and need to be manually nudged through.
- How much does the WC68 weigh?
- The Woodland Mills WC68 6-inch PTO Woodchipper weighs approximately 790 lb. Check your tractor's three-point hitch lift capacity before purchase — a Category 1 tractor typically lifts 1,200–1,800 lb at the hitch pins; Category 2 lifts 2,500+ lb.
- How often do the blades on the WC68 need sharpening?
- For typical property use (20–40 hours per year), sharpen the WC68's blades once per season. Heavy hardwood use cuts that to every 15–20 hours. A full replacement set runs roughly $80–$250 depending on blade count and material. See our woodchipper blade sharpening guide for the full process.
- Where is the WC68 made?
- Woodland Mills is headquartered in Ontario, Canada. The WC68 is assembled in Asia to Woodland Mills specifications, with quality control and distribution handled from their Canadian facility.
