Woodland Mills TFG55 PTO 5-inch Gravity-Feed Twin Flywheel Wood Chipper Review (2026): 5-inch Self-Feeding PTO Woodchipper
Woodland Mills' first gravity-feed PTO chipper — 5-inch capacity with patented Twin Flywheel Technology, sized for subcompact tractors.
- Cheapest Woodland Mills chipper at $2,415
- Patented Twin Flywheel system — secondary flywheel at 1,080 RPM throws chips faster and further
- 12 HP minimum — fits smaller subcompacts than the WC46
- Lightest in the WL lineup at 454 lb
- Gravity feed only — no hydraulic roller for forked material
- Twin Flywheel is new (fall 2024 launch); long-term owner data still thin
Twin Flywheel Technology — what it actually does
Twin Flywheel is Woodland Mills' patented two-flywheel design, introduced on the TF810 Pro in 2023 and rolled down to the TFG55 PTO in fall 2024. The primary chipping flywheel spins at 540 RPM and carries the three reversible knives — that's the slow, high-torque half of the system, sized so a subcompact tractor can keep the rotor loaded without bogging. The secondary flywheel runs at 1,080 RPM, roughly twice the chipping speed, and exists purely to move chips. It's a discharge fan, not a cutter. The marketing pitch is faster chip throw, less clogging, and better airflow through a smaller-HP machine.
In practice, the split makes sense on paper and the early reports from the gas-powered TFG55 GAS sibling suggest the discharge claim holds — chips clear the chute aggressively even on green, sappy material that tends to pack a single-flywheel design. What it does not do is replace a hydraulic feed roller. Twin Flywheel improves what happens after the knives bite; it does nothing for the moment of bite itself. If your bottleneck is getting forked, springy brush past the infeed, this technology is not the fix. If your bottleneck is straight branches stalling halfway down the chute, it genuinely helps.
TFG55 PTO vs Woodland Mills WC46 — the intra-brand call
This is the decision most Woodland Mills shoppers actually face. The TFG55 PTO is $2,415, 454 lb, 12-30 PTO HP, 5-inch gravity feed, three reversible knives, 3-year warranty. The WC46 is $3,220, 648 lb, 15-30 PTO HP, 4-inch hydraulic feed, same 3-year warranty. The TFG55 is $805 cheaper, almost 200 lb lighter, takes one more inch of material, and starts at lower PTO HP — meaningful on a Kubota BX or sub-25 HP machine that struggles to lift the WC46 on a 3-point hitch.
Where the WC46 still wins is unattended feed. The hydraulic infeed roller pulls forked, leafy, irregular brush through on its own; the TFG55 needs you to keep hands on every limb until the flywheel catches it. For a hobbyist clearing a few cords of straight branches a year, that's a non-issue and the TFG55 is the better dollar. For anyone running production cleanup — storm-down brush, multi-fork hardwood, anything you'd rather not babysit — the WC46's hydraulic roller is worth the $805 even though you lose an inch of capacity.
TFG55 PTO vs Woodmaxx MX-8500G+ — the cross-brand call
The Woodmaxx MX-8500G+ is the obvious cross-shop: both are 5-inch gravity-feed PTO chippers in the same price band. The MX-8500G+ runs $2,990, weighs about 720 lb, accepts 15-50 PTO HP, is USA-made, and carries Woodmaxx's 7-year warranty. The TFG55 is $575 cheaper, 266 lb lighter, starts at 12 PTO HP, and carries a 3-year warranty. On warranty alone the Woodmaxx wins decisively — seven years versus three is not close.
The TFG55 wins on subcompact fit. At 454 lb and 12 HP minimum, it mounts on a Kubota BX23S or John Deere 1025R without stressing the 3-point or starving the PTO. The MX-8500G+ at 720 lb is borderline-to-too-heavy for those tractors, and its rotary anvil really wants 20+ PTO HP to feed properly. Pick the Woodmaxx if you have 25+ HP and want the long warranty. Pick the TFG55 if you're under 25 HP, lift capacity is tight, or you simply want the cheaper machine and trust Woodland Mills' 3-year coverage.
Who this is actually for
The TFG55 PTO is sized, weighted, and priced for one buyer: the subcompact tractor owner who wants 5-inch capacity at the lowest credible price. The 12-30 PTO HP window is wider on the low end than almost anything in the class — the WC46 starts at 15 HP, the MX-8500G+ at 15, the Wallenstein BX42S typically wants 16+. A bone-stock Kubota BX1880 at 13 PTO HP technically clears the minimum, though you'll be limited to 3-inch material at that horsepower. A BX2380 or 1025R at the top of the range will run the chipper close to its 5-inch ceiling.
The hard limits are owner data and feed type. The TFG55 launched fall 2024, which means real-world hours on these machines are still being logged. Forum chatter is thin, and the few owner posts that exist trend positive but are too sparse to surface long-haul reliability patterns. The gravity-feed limit is the other watchout — anyone planning to chip a lot of multi-fork brush, vines, or springy material should either keep a hand on every limb or step up to a hydraulic-feed machine. For straight branches off a homestead woodlot, the TFG55 is the value pick of the class.

Who should buy the TFG55 PTO — and who should skip it
- Cheapest 5-inch PTO chipper from a reputable brand at $2,415
- 12 PTO HP minimum is the widest low-end window in the class — fits Kubota BX1880, BX2380, and John Deere 1025R without stress
- 454 lb is the lightest Woodland Mills chipper and well inside subcompact 3-point lift limits
- Twin Flywheel design genuinely improves chip discharge on green and sappy material
- $805 cheaper than the WC46 with one more inch of chipping capacity
- Category 1 quick-hitch compatibility and standard PTO shaft with shear-pin protection
- Backed by Woodland Mills' established 3-year warranty and direct-to-consumer service
- Gravity feed only — forked, leafy, or springy brush will hang up at the throat
- Three-year warranty looks short next to the Woodmaxx MX-8500G+ seven-year coverage
- Owner data is still thin; the model launched fall 2024 and long-haul reliability is unproven

TFG55 PTO — frequently asked questions
- What is Twin Flywheel Technology and does it actually matter?
- It's Woodland Mills' patented two-flywheel design: a 540 RPM chipping flywheel with the knives, plus a separate 1,080 RPM secondary flywheel that exists only to discharge chips. The point is to split torque and throw across two specialized rotors so a low-HP tractor can keep cutting while a faster fan moves chips out of the chute. It matters most for clog resistance and chip throw distance on green or sappy material. It does not improve infeed behavior — that's still gravity-only on the TFG55.
- TFG55 PTO vs WC46 — which Woodland Mills chipper should I buy?
- The TFG55 is $2,415 with 5-inch gravity feed; the WC46 is $3,220 with 4-inch hydraulic feed. Both carry a 3-year warranty. Buy the TFG55 if you want maximum capacity at minimum price, your tractor is under 25 PTO HP, or you're chipping mostly straight branches. Buy the WC46 if you'll be feeding forked, leafy, or irregular brush — the hydraulic infeed roller pulls material through on its own, which the TFG55 can't do. The intra-brand price gap is $805.
- How does the TFG55 PTO compare to the Woodmaxx MX-8500G+?
- Both are 5-inch gravity-feed PTO chippers in the same price band. The MX-8500G+ is $2,990 and carries a 7-year warranty but weighs 720 lb and wants 15-50 PTO HP. The TFG55 is $2,415, weighs 454 lb, runs on 12-30 PTO HP, and carries a 3-year warranty. The Woodmaxx wins on warranty and chip-feed aggressiveness. The TFG55 wins on price, weight, and subcompact-tractor fit. If your tractor is a BX or 1025R-class, the TFG55 is the easier mechanical match.
- Will the TFG55 PTO work on a Kubota BX or John Deere 1025R?
- Yes, and that's specifically what it was designed for. The 12 PTO HP minimum clears most BX-series and 1025R tractors, the 454 lb weight is well inside their 3-point lift capacity, and the Category 1 quick-hitch fitment matches both. Expect to be limited to roughly 3-inch material on a 13 HP BX1880 and closer to the full 5-inch capacity on a 23-25 PTO HP machine. This is the lightest Woodland Mills chipper in the lineup and the easiest one to mount on a subcompact without scale-tipping.
- How does a gravity feed handle forked branches and brush piles?
- Not as well as a hydraulic infeed. Gravity feed relies on chute angle, knife geometry, and the operator pushing material in — there's no powered roller pulling brush through. Straight branches feed fine. Y-forked limbs, leafy tops, and springy vines tend to hang up at the throat and need to be re-fed or broken down by hand. The TFG55's Twin Flywheel design helps clear chips fast, but it doesn't fix infeed behavior. If most of your material is forked or messy, the WC46's hydraulic feed is worth the upcharge.
- Is there enough owner feedback yet to trust the TFG55 PTO?
- Not deeply. The TFG55 PTO launched in fall 2024, so by spring 2026 there are roughly 18 months of real-world hours on the earliest units. Woodland Mills reports strong adoption and positive reviews, and scattered Facebook group posts and a few YouTube walkarounds back that up. What's missing is the multi-year reliability picture — bearings, knife life on the secondary flywheel, gearbox longevity. The WC-Series has a decade of owner data behind it; the TFG-Series does not yet. The 3-year warranty covers the period during which most teething issues would surface.
- How much HP do I need to run the TFG55 PTO?
- The TFG55 PTO needs 12–30 PTO HP. That's PTO horsepower (roughly 85–90% of engine HP). A 14 HP engine tractor produces about 12 PTO HP. Comfortable range: 15–27 PTO HP.
- What warranty does the TFG55 PTO come with?
- Woodland Mills covers the TFG55 PTO with a 3-year warranty. Covers manufacturing defects; excludes wearing parts and cosmetic damage.
- What can the TFG55 PTO actually chip in real-world use?
- Rated for 5-inch branches. In practice, green softwood chips reliably at rated max. Seasoned hardwood at 5 inches slows the feed rate and bogs the flywheel on knots — comfortable working capacity on hardwood is 3.5–4.5 inches. The mechanical feed handles straight material well but can stall on forked branches.
- Is the TFG55 PTO worth buying?
- At $2,415, the TFG55 PTO is the value sweet spot — enough capacity for regular property use without commercial pricing. The 3-year warranty is shorter than competitors — factor that into your decision.
