Valtra re-vamps A Series tractors

Bringing its entire tractor offering to its four generation, Valtra has added five new models to its compact A Series tractor range. Richard Bradley reports.

Valtra’s fourth generation A Series takes styling cues from the firm's larger tractor ranges.

Heading up Valtra’s latest tractor launch was its smallest A Series, which sees two sub-100hp models outed for seven models in the 75-130hp bracket.

 

Along with three all-new chassis sizes, Valtra’s fourth generation A Series gains family styling from the firm’s larger N, T and S ranges, Stage 4 engines and a new power-shuttle transmission.

It has to be noted, the range, which shares many Agco components with Massey’s Global Series, retains Valtra’s Finish flare particularly with slick styling, handy features and cab layout. Also differing from MF’s range, Valtras for Europe, Australia and New Zealand will be assembled at the firm’s factory in Suolahti, Finland, along with its N and T Series.

 

Markets in Africa and South America will be supplied by a Brazilian factory, where cabbed and open platform models will be available.

Engine and Transmission

Depending on model, power for the A Series comes from a 3.3 litre, three-cylinder, or a 4.4l, four cylinder Agco Power engine, both of which meet Stage 4 emission regulations. The smallest in the range A74 model meets emissions only with exhaust gas recirculation, while A84-A134 models require diesel exhaust fluid.

 

Emission regulation equipment on all models resides under the right hand steps, improving visibility around the exhaust and cab A-pillar.

Model dependent, the A Series range uses 3.3l or 4.4l Agco Power engines.

Engine control benefits from an electronic throttle and a speed memory, to quickly resume set working revs.

Keeping gearing simple, the entire range features Agco’s own two-range, six-speed mechanical transmission as standard, offering 12 gears in forward and reverse and 40kph top speed. Creeper gearbox offering 12 addition speeds is available as an option.

 

Valtra’s electronic power shuttle is also a standard feature, which benefits from a handy integrated park lock. While this is the standard spec, the firm says there will eventually be the option of a lower-spec and simpler mechanical shuttle.

 

All models feature a de-clutch button on the gear lever, and a brake to neutral feature is also standard fitment – ideal for loader duties as the clutch pedal is not required.

 

A slight hindrance to gear changes is the armrest-mounted electronic loader joystick which can get in the way when selecting some gears.

Cab and Controls

Views to loader’s maximum height are possible with the optional sunroof.

While it may feature a common Agco cab frame, the A Series certainly gets the Valtra fit and finish on the inside.

 

Taken from its N and T Series, a mix of analogue dials and an LCD display is used in the dash to show a range of working information. Ideal for loader duties, a panoramic roof is available as an option, which allows good views of the attachment to the loader’s maximum height.

 

Control-wise, throttle and speed memory, linkage raise and lower, pto engagement, four wheel drive and diff lock reside on the side panel and fall easily to hand, with floor mounted gear lever falling to hand just in front of the armrest. Sporty spool levers and linkage adjustment dials are located further across the control panel, with other controls, such as lighting, grouped on the B pillar.

 

Mounted directly to the right-hand armrest, the A Series features an electric joystick as standard if fitted with optional loader (simpler mechanical joystick is optional); third service and boom float buttons also reside on or close to the joystick.

Regular functions are neatly grouped together close to the armrest.

Hydraulics and Backend

All seven models are available with up to three rear spool valves and use an open centre hydraulic system. Small-frame A74-94 models get 65 litres per minute of flow, while medium and large framed models benefit from a twin-pump arrangement, which offers up to 98l/min of flow – an in-cab switch allows both pumps to be engaged to boost flow for more demanding tasks.

Rear linkage can lift up to 5.2tonnes, and up to three spools can be specified.

Options up-front include Quickie’s latest Q Series loaders, which can be fitted directly from the factory.

 

Drive to rear implements is taken care of via a two speed 540/540eco pto as standard, with medium and large frame models getting further options of two speed 540/1,000, or three speed 540/540e/1,000 pto.

 

Small frame models use a mechanical selector for pto speed selection, while medium and large frame models feature an electronic dial selector.
