New Holland Boomer 30 to Workmaster 37 specifications

The Boomer 30 and Boomer 37 documents describe different equipment packages

New Holland’s Australian Boomer 30 publication identifies a four-cylinder engine and offers either synchronized shuttle gearing or a hydrostatic transmission. Rear and mid PTO positions are separate: the rear drive is included, while the mid drive is optional. A tractor offered with a rear mower therefore does not automatically have the mid drive needed for a belly mower.

That publication’s 920-series backhoe arrangement uses a subframe and requires the front loader to be fitted. Check the complete attachment package when comparing a bare tractor with one advertised as backhoe-ready. A rear hitch alone does not establish that the brochure’s backhoe mounting and loader requirement are satisfied.

The cab specification is not the ROPS shipping configuration

The North American Boomer 37 cab sheet describes a turbocharged three-cylinder engine. Its mechanical transmission has fewer ratios than the larger cab models printed beside it; the hydrostatic alternative has three ranges. Read the Boomer 37 column itself when evaluating a used machine, especially when a seller supplies a brochure covering several models.

The sheet gives higher PTO output for the geared version than for the hydrostatic version, despite the shared engine rating. That matters for a PTO-driven implement: compare the relevant PTO line, not just the engine figure in the advertisement.

New Holland also publishes a separate cab weight. It should not replace a ROPS shipping weight without identifying the configuration change. Its cab equipment includes heating, air conditioning, opening windows and a mechanical-suspension seat; rear remotes remain optional.

Verify the fitted remotes before assuming a cab-equipped tractor can operate a rear hydraulic implement.

The L3BL Workmaster 35 has a synchronized shuttle and unsynchronized ranges

The manufacturer’s September 2014 order specification identifies the Workmaster 35 with its L3BL engine. It lists four main gears and three ranges, producing twelve ratios in each direction. Those ratios come from the gear-and-range combination, not from twelve independently selected main gears.

New Holland calls the shuttle synchronized while expressly describing the main gears and ranges as non-synchronized. Those are separate mechanisms. A listing that says “synchro shuttle” does not establish a fully synchronized main gearbox.

The hydrostatic option is listed separately, with its own direction pedals and cruise control.

WORKMASTER names continued through a later range change

New Holland’s February 2017 announcement introduced a WORKMASTER compact lineup named 35 and 40 for North America. The older Workmaster 33 and 37 records here should not be treated as alternate names for that announcement’s tractors. Match the model plate and engine identification before comparing their specifications.

The announcement describes a dedicated implement-flow supply and an automatic emissions system for the new lineup. “Automatic” describes operation; it does not identify an earlier machine’s exhaust equipment. Use the tractor’s emissions label and its own operating instructions when discussing regeneration or service, rather than transferring a procedure from another WORKMASTER model.

The Workmaster 25 pedal layout depends on its transmission

The Workmaster 25 operator excerpt places the differential-lock pedal on opposite sides of the platform for hydrostatic and mechanical versions. Its hydrostatic cruise lever mechanically retains the forward pedal. The mechanical model instead requires the tractor to stop before changing the main gears; its shuttle and range levers remain separate controls.
