The tow-behind frame: road-legal in theory, not built for daily highway miles
The TX1000 ships with a real trailer chassis: 13-inch radial tires, 55-inch wheelbase, a 2-inch ball coupler, tail and brake lights, and a 7-pin connector for synchronized turn signals. Tongue weight is a manageable 198 lb on a 1,874 lb machine, so a half-ton truck or even a heavy SUV can pull it. That is genuinely more than most homeowner chippers ever offer.
The honest caveat is that 13-inch passenger-style tires and a single non-braked axle put this closer to a utility-trailer chipper than a Vermeer-grade DOT job-site trailer. It is fine for surface-street moves between properties, jobsite-to-storage, or a 30-minute interstate hop. It is not what you want bouncing down the highway at 70 mph five days a week. Treat it as a tow-behind, not a road tow.
Commercial gas vs tractor PTO at the same price
At $14,699 the TX1000 lands roughly twice the price of the Woodmaxx MX-9900 PTO chipper ($7,350) and the obvious question is why. The answer is the engine and the frame: you are paying for a self-contained 35 HP gas powerplant, a road-towable chassis, and lights instead of borrowing power from a tractor you already own. If you have a 40+ HP tractor, the MX-9900 is the better dollar-per-chip value and we recommend it first.
The TX1000 wins when you do not have a tractor, when you need to move the chipper to the wood instead of the wood to the chipper, or when you are running a small tree-service crew that bills by the job and cannot tie up a tractor all afternoon. The Zonsen GB1000EI is a Chinese-built commercial EFI engine, not a Honda GX or Kohler Command — parts and dealer support are mail-order, so factor that into your downtime math.
The ceiling: when you actually need Vermeer or Bandit
The TX1000 is light-commercial. It will handle a homeowner property, a landscape crew clearing a lot line, or a part-time tree service running a few jobs a week. It is not a daily-driver chipper for a full-time crew chipping eight hours a day. Hydraulic-feed clutches, knife steel, and the engine itself are spec-grade rather than over-built, and there is no national dealer network for parts or emergency service.
If you are billing five days a week, towing 50+ highway miles daily, or feeding the chipper continuously, you need a Vermeer BC600XL or Bandit 65XP. Those machines run $35,000 to $55,000 and come with dealer service, parts in-stock, and the build quality to absorb daily abuse. The TX1000 is the right answer for the buyer who needs a real 8-inch hydraulic-feed gas chipper but cannot justify triple the cash outlay — just go in with eyes open about the trade.

Who should buy the CROBA TX1000 — and who should skip it
- You need an 8-inch hydraulic-feed chipper but do not own a 40+ HP tractor to run a PTO unit
- You run a small or part-time tree-service crew and need to tow the chipper between jobsites
- You want a self-contained gas chipper under $15,000 — the dealer-network alternatives start near $35,000
- Intelligent feed control and quick-reverse rollers reduce jam downtime for a less experienced operator
- EFI electric start and a 4.3-inch LCD diagnostic display are unusual at this price
- 2-year machine and engine warranty is competitive for the commercial-gas segment
- Real trailer chassis with brake lights and a 7-pin plug, not a glorified yard cart
- You will be feeding the chipper full-time, five days a week — this is light-commercial, not daily-commercial
- You already own a capable tractor — the Woodmaxx MX-9900 PTO chipper does the same job for half the price
- You need dealer support, in-stock parts, or emergency service — MechMaxx is mail-order only
- You need to tow it 50+ highway miles daily — the 13-inch tires and single non-braked axle are not built for that
- You expect Honda GX or Kohler Command engine longevity and parts availability — Zonsen is solid but not equivalent
- Budget is under $10,000 — look at smaller 6-inch tow-behinds or a PTO setup instead

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
- Is the CROBA TX1000 actually DOT-legal for highway towing?
- It has the equipment a DOT-legal trailer needs: brake lights, turn signals, a 7-pin plug, and a standard 2-inch ball coupler. State titling and registration requirements vary, and the 13-inch tires plus single non-braked axle are not rated for sustained highway speed. Treat it as legal for short jobsite tows and check your state's trailer registration rules before any long haul.
- What engine is in the TX1000 and where is it made?
- A Zonsen GB1000EI, a 1000cc 35 HP EFI commercial gas engine built in China. It is not a Honda GX or Kohler Command. Zonsen makes reliable engines for the price, but parts and service are mail-order from MechMaxx rather than walk-in at a local small-engine shop.
- How does the TX1000 compare to a Vermeer BC600XL?
- The Vermeer is a true daily-commercial chipper with dealer support, costs roughly $35,000 to $40,000, and is built for full-time tree-service abuse. The TX1000 costs about a third as much and is built for part-time or small-crew use. Same 6-to-8-inch capacity class, very different service life and support model.
- Can I mount the TX1000 on a skid steer?
- No. The TX1000 is a self-contained gas-powered tow-behind chipper with its own engine and trailer chassis. It is not a skid-steer attachment.
- What is the real warranty?
- MechMaxx lists a 2-year warranty on both the machine and the Zonsen engine. Claims are handled direct through MechMaxx since there is no dealer network, so expect mail-order parts and remote troubleshooting rather than next-day service.
- Is the listed price stable or is it always on sale?
- MechMaxx shows the TX1000 at $14,699 sale against a $20,999 list. The sale price has been the effective street price for an extended period — treat $14,699 as the real number rather than a limited-time deal.
- CROBA TX1000 vs dch7 — which should I buy?
- See our head-to-head comparison for the detailed breakdown. In short: the CROBA TX1000 at $14,699 offers 8-inch capacity with hydraulic feed. The right pick depends on your tractor HP, branch size, and whether you need hydraulic feed for forked material.
- Is the CROBA TX1000 worth buying?
- At $14,699, the CROBA TX1000 is the premium/commercial tier — justified only for high-volume use or buyers who need max capacity. The 2-year warranty is shorter than competitors — factor that into your decision. Buy through Amazon for easier return protection.
- How much HP do I need to run the CROBA TX1000?
- The CROBA TX1000 has a built-in 35 HP Zonsen GB1000EI EFI commercial. No external power source needed.
- What warranty does the CROBA TX1000 come with?
- MechMaxx covers the CROBA TX1000 with a 2-year warranty. Covers manufacturing defects; excludes wearing parts and cosmetic damage.
- What can the CROBA TX1000 actually chip in real-world use?
- Rated for 8-inch branches. In practice, green softwood chips reliably at rated max. Seasoned hardwood at 8 inches slows the feed rate and bogs the flywheel on knots — comfortable working capacity on hardwood is 6.5–7.5 inches. The hydraulic feed handles forked and crooked material well.
