T4 tractor series goes to Tier 4

With model designations of T4.85 /T4.95/T4.105/T4.115 the machines offer maximum power of 84, 98, 106 and 114hp, respectively, from 4-cyl. Tier 4, FPT engines of 3.4L. They have cooled exhaust gas recirculation and diesel particulate filtering to meet industry emission regulations. The engines offer torque backup to 35%, and a constant maximum power range of 1900-2300 rpm. They have the ability where suitable to run a 20% bio-diesel fuel mix.

Engine power passes to a New Holland transmission with a wet clutch (power shuttle) for clutch-free movement from forward to reverse. Adjustable three-stage modification for aggressiveness, dependant on the task at hand, should ideally suit loader work. A choice of 20x20 or 24x24 speeds is offered: the former uses five ranges to deliver creep speeds down to 250m/h, making them suitable for growers; the latter offers three ranges, and a hi-lo power-shift, which results in a 15% speed reduction and an increase in torque at the wheels of 18%.

The rear transaxle uses epycyclic reduction hubs for positive transmission of power from engine to the ground through a number of tyre options.

The Cat2 three point linkage has a maximum lift capacity of around 3.9 tonnes, so should handle most jobs asked of it. The external hydraulic system uses a fixed displacement pump which delivers 64L/min, and combines with a dedicated power steering pump of 37L/min to provide a system total of 101L/min. 

These tractors will be an ideal choice for livestock and mixed farming sectors, likely fitted with frontloaders. With this in mind all models are fitted with two mid-mount hydraulic connectors, which work in conjunction with an integrated joystick to the driver’s right, alleviating the need for the installation of a non-factory item.

All models are available in ROPS or cabin configuration, both variants meeting all ROPS and FOPS regulations to ensure the operator is keep safe in an accident. The ROPS version has a sunshade, vinyl covered seat with mechanical suspension, and large cable operated controls to withstand the elements. There is also some attention to detail to reduce noise – sound deadening material beneath the rubber mats covering the flat platform. Storage bins are built into the rear fenders.

By contrast, the cabin optioned versions offer high levels of comfort for the operator, with a hi-vis roof hatch to help loader work, air conditioning with 10 adjustable vents, and a cloth trimmed seat with air suspension and 15 degrees of lateral swivel in each direction. This is supplemented by a buddy/training seat to the driver’s left. To the right side of the seat is the Command Arc console which brings controls for throttle, linkage, external remotes and PTO within easy reach of the driver. 

All models have a one-piece lift-up hood for easy access, making daily checks a breeze; service intervals are a respectable 500 hours.

NZ operations manager for New Holland, Kyle Baxter, summed up the new range by commenting that in the competitive livestock and mixed farming sector, farmers are becoming more demanding and want more flexibility and comfort.
