Woodland Mills WC68’s “over 40 PTO hp” line: which tractors clear it

Woodland Mills rates WC68 at 20–50 PTO hp, then ties full 6-inch logs at full infeed speed to over 40 PTO hp. Many mid-size compact tractors sit within a couple of horsepower of that line, and for several the transmission or the document decides it. A tractor exactly at 40 is inside the range but not over the line.

THE DECISION IN NUMBERS

Tractors near WC68’s over-40-PTO-hp full-feed line

Tractor figures from the site’s current profiles (reviewed November 7–9, 2026). WC68: 20–50 PTO hp; full 6-inch at full feed over 40 PTO hp (Woodland Mills page, reviewed November 7, 2026).

Range and condition

WC68’s 20–50 PTO hp range decides whether the chipper is within the maker’s limits. The over-40 statement is a capacity condition: below it, WC68 still works, but expect to slow its hydraulic feed on 6-inch material. Above 50 PTO hp, WC68 is outside its range altogether.

Tractors just over

On the site’s profiles: New Holland Boomer 50 gear 42.5; KIOTI NX5010 synchro 41.8; KIOTI NS5310H 41.8 (brochure); KIOTI DK5020 41.5; Kubota MX4900 41.3; Massey Ferguson MF 2E.50 Mech 40.7 (spec sheet; 41.4 web); Kubota L4802 gear 40.5.

Tractors at or just under

New Holland Boomer 50 HST 40.0, exactly on the line; Kubota L5070 Premium 39.8; Kubota L4802 HST 39.0; KIOTI NX5010H 38.9; MF 2E.50 HST 38.5 (web 35.2); KIOTI NS5310H 36.6 on its web page. Several of these pairs differ only by transmission or by document.

What to do near the line

Confirm the PTO figure for the exact transmission and, where the brochure and web page disagree, ask the dealer which applies. If 6-inch material is routine and the tractor is at or under 40, ask Woodland Mills what feed rate to expect, or compare WC88, which starts at 35 PTO hp.

Take these questions with you.

  1. What is my tractor’s PTO figure for its exact transmission?
  2. Do the brochure, web page and manual agree on it?
  3. How often will I chip material near 6 inches?
  4. What feed rate does Woodland Mills expect at my PTO rating?

Keep these questions with your exact tractor and attachment details.

FIELD GUIDE

Chipper feed rate vs. throughput: what can estimate job time?

A faster-looking specification does not necessarily tell you how soon a brush pile will be cleared. Feed speed measures movement into the machine; processing volume measures an amount of material over time. Maximum branch diameter answers a third question. Compare those labels separately before asking a seller for a time estimate tied to your job.

Meeting an attachment’s minimum PTO horsepower exactly: what zero margin means

A tractor whose PTO rating equals or barely exceeds an attachment’s minimum is inside the published range, and nothing more. Several makers attach separate capacity statements well above their minimums. When the margin is zero or one horsepower, also check the source of each number and what the maker expects at that power.

Tractors near 45 PTO hp: where the small-attachment ceilings stop

Several flails and chippers on this site stop at 45 PTO hp: WoodMaxx FM-62, Farmer-Helper FH-BX62S, Farmry WCAP5 Pro (Category 1) and Farmry LFP47 (basis unspecified). TMG’s TFMS50 stops at 50. A cluster of current tractors sits within 2 hp of 45, and for most of them the transmission, the document or the hitch decides the answer.
