New Holland Boomer 35 to Workmaster 50C specifications

Gear choices separate the later Boomer chassis sizes

The later North American Boomer range gives the 35 and 40 a synchronized shuttle with three ranges, while the 45 and 50 use four ranges. The larger model therefore offers more fixed speed selections; choosing hydrostatic drive changes that comparison again. A tractor advertised simply as “Boomer 40” needs its generation and transmission identified before an implement power figure is useful.

Cab availability is another boundary. New Holland offers a factory cab on the later 40, 45 and 50, while the 35 remains the open-platform choice in that range. The maker's current transmission description reserves its servo-assisted hydrostatic option for the Boomer 55.

Do not assume that extra feature is included on a used 45 or 50 because a general Boomer advertisement mentions it.

EasyDrive D models need their own emissions and loader information

The 2015 Boomer 46D and 54D announcement identifies FPT common-rail engines and describes internal exhaust-gas recirculation with a particulate-matter catalyst. It expressly contrasts that arrangement with a filter requiring interrupted work for regeneration. That is the manufacturer's description of those North American D models, not evidence that every Boomer in this comparison uses the same exhaust system.

EasyDrive also changes the demonstration. A single travel pedal works with a separate direction shuttle and an adjustable acceleration response; it is not the same control arrangement as a dual-pedal hydrostatic tractor. The D-series brochure pairs these machines with the 250TLA loader.

Its load chart measures capacity both at the pin and farther forward, where the permitted load is lower. Match the attachment and load position before comparing a loader's headline lift number with a rear-hitch rating.

Workmaster C attachment names are size-specific

The current Workmaster C page assigns different loader and backhoe combinations to its smaller and larger tractors. The 45C and 50C use the larger pair listed below; the 35C/40C attachment names elsewhere on that same page do not establish compatibility. The manufacturer also gives the larger tractors a servo-hydrostatic transmission option alongside their synchronized gear shuttle.

The C-series engine description includes common-rail injection and glow plugs, with an engine heater offered as a dealer accessory. A cold-weather advertisement does not establish that the heater is fitted. Check the actual installation.

Likewise, the current manufacturer horsepower labels differ from the earlier reference entries retained here, so those entries are recorded separately instead of treating the model's number as its engine rating.
