Woodland Mills WC46 vs TFG55 PTO: hydraulic feed or a lighter chipper
A larger advertised branch diameter does not make the TFG55 PTO a direct upgrade from the WC46. It uses gravity feed and weighs substantially less; the WC46 supplies powered, adjustable feeding through its own hydraulic system. Neither needs tractor rear remotes. This makes the choice a balance between feed control, the tractor’s approved rear load and the brush you handle. Compare the actual cutting throats and power qualifications as well, because the five-inch TFG55 headline does not promise that capacity at minimum horsepower.

The differences that matter.
01
Powered feed versus gravity feed
WC46 has an adjustable hydraulic feed roller powered by its own tank and belt-driven pump. TFG55 uses gravity feed and has no hydraulic feed circuit. Neither requires tractor rear hydraulic remotes.
Choose based on the feeding method you want to operate and maintain. Hydraulic feed is an additional onboard system; absence of tractor remotes does not rule it out.
Current retained manuals list WC46 at 587 lb product / 693 lb shipping and TFG55 at 346 lb product / 454 lb shipping.
The lighter implement is worth examining when rear load is a constraint. It still needs approval for its center of gravity, hitch geometry and ballast; neither shipping weight is a substitute for installed load.
WC46 has a 4 × 6-inch throat and four-inch maximum, with over 20 PTO hp required for full logs at full feed speed. TFG55 has a 5 × 5-inch throat and a five-inch stated maximum; its published minimum PTO-power figures conflict as described below.
A square five-inch opening is not universally more accommodating than a 4 × 6-inch rectangle. Assess forks and diameter separately, then confirm realistic feeding expectations at your available PTO power.
TFG55 splits cutting and chip discharge between two flywheels
WC46 uses a single flywheel. TFG55 uses a primary cutting flywheel driven from a 540 RPM PTO and a faster secondary discharge flywheel; its secondary speed is not the tractor’s input setting.
Confirm 540 RPM PTO operation. The twin-flywheel layout is a design distinction, not an independently measured guarantee of chip-throwing distance or throughput.
Consider WC46 when adjustable powered feed is the priority
Within the documented 15–30 PTO-hp range, shortlist WC46 if you want its hydraulic roller and the tractor is approved for the heavier rear implement. The current observed price is $805 above TFG55. Check the full-log power threshold and hydraulic setup/maintenance obligations before paying for that feeding system.
Consider TFG55 where lower implement weight and gravity feed suit the task
TFG55 is the lighter and lower-priced option on the retained figures. It may suit a buyer who accepts gravity feed and whose tractor and typical branch sizes meet the documented limits. Resolve the 12-versus-15 PTO-hp minimum inconsistency before selecting it for a tractor below 15 PTO hp.
TFG55 product page and manual specification table give a 12 PTO-hp minimum, but the manual hitch paragraph says 15–30 PTO hp. Use 15 as a conservative screening floor pending manufacturer clarification; do not state that the conflict proves 12 hp operation is prohibited.
TFG55 web shipping text labels 346 lb as shipping weight. Manual p9 separates 346 lb product from 454 lb shipping; this comparison uses the manual distinction.
