THE ACREAGE EQUIPMENT FIELD GUIDE

WORKMASTER or Boomer: the same engine and PTO figures, a different 24-inch lift

New Holland sells WORKMASTER and Boomer compact tractors side by side. In its March 2025 brochure, the WORKMASTER 35 and Boomer 35, and the WORKMASTER 40 and Boomer 40, list the same engines, the same PTO horsepower and the same 1,808-lb ball-end lift. Their 24-inch lift figures differ, and the Boomer 45, 50 and 55 move to a larger frame.

What matches

The brochure gives the WORKMASTER 35 and Boomer 35 35 gross hp and 29.7 (gear) or 28.0 (HST) PTO hp, and the WORKMASTER 40 and Boomer 40 40 gross hp and 34.0 or 32.0. All four list a 1.9-liter turbocharged three-cylinder, 1,808 lb at the ball ends and a Category I hitch. PTO-based attachment screens come out the same for each pair on these figures.

What differs

The brochure’s WORKMASTER table gives 1,433 lb 24 inches behind the ball ends; its Boomer table gives 1,345 lb for the Boomer 35 and 40. The WORKMASTERs are listed at 3,067 lb, the Boomer 35 and 40 at 2,804 lb (gear) or 2,870 lb (HST) with ROPS. The Boomer 40 is offered with a factory cab; the WORKMASTER 40 is ROPS only.

The bigger Boomers

The Boomer 45, 50 and 55 use a longer 73.2-inch wheelbase, 16x16 gear transmission and a 2,756-lb ball-end lift with 2,116 lb at 24 inches, about 680 lb more at 24 inches than the WORKMASTER 40. That is the step to make for heavier rear attachments, not the step from WORKMASTER to Boomer at the same horsepower.

The manual’s PTO figures

New Holland’s November 2023 WORKMASTER 35/40 manual lists observed PTO horsepower of 27.4/25.7 (WORKMASTER 35) and 30.8/29.0 (WORKMASTER 40), measured with rear 540 at 2,509 engine rpm, against 29.7/28.0 and 34.0/32.0 in the brochure. On the WORKMASTER 40 HST, that gap decides WC46’s 30-hp ceiling and FM-78’s 30-hp minimum. No Boomer manual was reviewed.

Take these questions with you.

  1. Is the tractor a WORKMASTER or a Boomer, and which 24-inch lift figure applies?
  2. Which PTO figure does the operator manual give for the PIN on offer?
  3. Is a cab needed, and does that change the model choice?
  4. Would a Boomer 45 or larger better suit a heavy rear attachment?

Keep these questions with your exact tractor and attachment details.

FIELD GUIDE

Same engine, different tractor: why engine horsepower does not predict PTO power or lift

Manufacturers often fit one engine to several tractors. The engine figure stays the same, but PTO horsepower, lift capacity and width change with the transmission, frame and hitch. Screen attachments on the figures for the exact model, never on the engine alone.

Read the guide →FIELD GUIDE

More horsepower, same lift: tractor series that share one hitch rating

Within a tractor series, the higher-horsepower model often has exactly the same three-point lift rating as the smaller one. KIOTI rates the NX4510 through NX6010 at 45 to 60 gross hp and lists every one at 3,177 lb at 24 inches. More power lets you run a bigger PTO attachment; it does not let the hitch lift a heavier one.

Read the guide →FIELD GUIDE

Which load point does that lift figure belong to? Checking footnotes against the manual

A three-point lift rating means little without its load point. Manuals usually give two figures: at the lift point (lower-link ends) and 24 inches behind. Brochures often print one, with a footnote. KIOTI’s September 2025 NS brochure prints 2,940 lb with a “24 inches aft of hitch” footnote, but its manual gives 2,940 lb at the lift point and 2,493 lb at 24 inches.
