THE ACREAGE EQUIPMENT FIELD GUIDE

Around 30 PTO hp: where small-attachment ceilings and mid-size minimums meet

Several attachments on this site change at exactly 30 PTO hp. Woodland Mills’ WC46 and TFG55 stop there; WoodMaxx’s FM-78 family and TMG’s TFM60 start there. A tractor just under 30 can use the first group and not the second, and one just over 30 the reverse. Kubota’s L3770 Deluxe (28) and L3970 Premium (30.9) sit on either side.

THE DECISION IN NUMBERS

Tractors near 30 PTO hp against 30-hp limits

Tractor PTO and engine figures from this site’s profiles, each with its own manufacturer sources. Attachment limits from retained product evidence reviewed November 7, 2026. TFM60’s 30–60 hp range is basis-unspecified.

Two groups that do not overlap

Woodland Mills rates WC46 at 15–30 PTO hp and TFG55 up to 30. WoodMaxx rates FM-78, FM-78H and FM-78 Y at 30–65 PTO hp. TMG rates TFM60 at 30–60 hp without a basis. A tractor at exactly 30.0 PTO hp is at both edges; anything else is in one group or the other on these products.

Tractors on either side

On this site, the Kubota L3770 Deluxe (28), LX3520 HSD (28.7) and Mahindra 1640 HST (27.7) and Shuttle (29.9) are under 30. The Kubota L3970 Premium and KIOTI CK3520 manual (30.9), Mahindra 4540 (31) and Kubota LX4020 HSD (32.6) are over. The 1640 Shuttle is 0.1 under; the L3970 and CK3520 are 0.9 over. Small margins either way should be confirmed with the attachment maker. New Holland’s WORKMASTER 35 gear (29.7 in its April 2025 brochure) is under 30; the 2026 WORKMASTER 35C is over it in gear (31.0) and HST (30.1), the HST by the narrowest margin in the table.

Engine figures are well above 30

Every tractor in the table has an engine figure between 34.9 and 41 hp. For attachments rated without a basis, such as TFM60 or Farmry’s LFS (15–35), the engine reading puts all of them over 30, and several over 35. Wallenstein’s BX36S, rated to 30 engine hp, is exceeded by all of them. Check the basis before treating 30 as a PTO line.

Choosing near the line

If a tractor is just under 30 PTO hp, the small chippers and mid-size mowers with lower minimums (FM-62 from 24) are the clear choices. Just over 30, the 70-inch FM-78 family opens and the small Woodland chippers close; WC68 (20–50) covers both sides. Do not buy toward a figure the tractor does not have; a dealer’s different PTO number moves the result.

Take these questions with you.

  1. Is my tractor’s PTO rating above or below 30 hp, and by how much?
  2. Does the attachment rate its 30-hp limit in PTO or engine horsepower?
  3. If my margin is under 1 hp, will the maker confirm the pairing?
  4. Is there an attachment whose range covers my tractor with more margin?

Keep these questions with your exact tractor and attachment details.

FIELD GUIDE

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.

Read the guide →FIELD GUIDE

When the tractor is too strong: attachment maximum horsepower

Most horsepower checks look at the minimum. Many small chippers and flail mowers also publish a maximum, and a larger tractor can be outside the range for a lighter attachment. Treat the maximum as a published limit with its own horsepower basis. Ask the maker before assuming a light attachment is the safe choice.

Read the guide →FIELD GUIDE

Deluxe, Premium and model numbers: why tractor names do not rank power

A higher trim level or a bigger model number does not guarantee more PTO power or lift. Kubota’s Grand L70 range shows both cases: a Deluxe model with more PTO power than a Premium, and two Premium models with the same engine model and different ratings. Screen attachments on the published figures for the exact model.

WORKMASTER 35C and 40C vs 35 and 40: the PTO ratings that change the fit

New Holland’s 2026 WORKMASTER 35C and 40C list more PTO power than the WORKMASTER 35 and 40 still on its site, and the gain crosses attachment limits. The gear 35C moves over 30 PTO hp and the gear 40C over 35, which swaps some chippers and flail mowers in and out.
