Who should buy the CROBA TX1000 — and who should skip it
- You don't own a tractor (or don't want to tie one up) and need a self-powered chipper.
- Your typical branches are 6–8 inches in diameter.
- You regularly chip forked, crooked, or limby brush that hangs up on mechanical-feed chippers.
- You plan to put the chipper through commercial-scale hours (50+ per year). Look for a model with a longer warranty — wearing parts and bearings are the typical failure points.
- You'll chip only a few times per year. At $7,499, renting might be cheaper — see our rental vs buying calculator.
CROBA TX1000blade replacement & sharpening
Four flywheel knives on the 8-inch commercial disc — swap all four at once and re-torque in a star pattern to keep balance.
Hydraulic feed means you can't push past dull blades; the rollers just stall. Track hours and sharpen on schedule.
Commercial-grade bed knife is thicker and can usually be re-ground twice before replacement.

- 01Stop the machine and isolate power
Shut the engine off, disconnect the spark-plug boot, and wait until the CROBA TX1000 flywheel has fully stopped. Do not open the hood while it is still spinning down.
- 02Open the discharge or flywheel access cover
Remove the bolts on the CROBA TX1000 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 CROBA TX1000 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 alloy steel.
- 07Balance the set
Remove equal material from every blade in the set. On the CROBA TX1000'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 55–65 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 engine and idle for 30 seconds before ramping to full RPM. Feed one small test branch before returning to normal work.
CROBA TX1000 — frequently asked questions
- What engine does the CROBA TX1000 use?
- The MechMaxx CROBA TX1000 8-inch Commercial Woodchipper is powered by a 35 HP commercial gasoline engine. Parts and service for this engine are typically available through the manufacturer or an authorized small-engine service center.
- What's the maximum branch diameter the CROBA TX1000 can chip?
- The MechMaxx CROBA TX1000 8-inch Commercial Woodchipper is rated for branches up to 8 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 7-inch hardwood as your comfortable working size.
- What's the warranty on the CROBA TX1000?
- MechMaxx covers the CROBA TX1000 with a 2-year warranty. Wearing parts (blades, belts) are excluded under normal use; commercial-scale use may require the manufacturer's commercial warranty tier.
- Does the CROBA TX1000 have reversible hydraulic feed?
- Yes. The CROBA TX1000 uses hydraulic feed rollers with a reversible control bar. Reverse lets you back out jams without stopping the flywheel, and lets you align crooked branches before committing them to the chipper. This is standard on all hydraulic-feed PTO chippers in this tier.
- How much does the CROBA TX1000 weigh?
- The MechMaxx CROBA TX1000 8-inch Commercial Woodchipper weighs approximately 1,650 lb. Plan for a trailer, skid steer, or equivalent for moving it between work sites.
- How often do the blades on the CROBA TX1000 need sharpening?
- For typical property use (20–40 hours per year), sharpen the CROBA TX1000'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 CROBA TX1000 made?
- MechMaxx chippers are assembled with globally sourced components. The chipper frame, feed system, and flywheel are imported. MechMaxx distributes from a US warehouse.
