These include a digital instrument cluster, a bigger capacity 55A alternator and a much larger 27.6-litre fuel tank, to allow for longer working days.

The dash-mounted instrument cluster displays the odometer, ground speed, fuel level and coolant temperature, engine rpm, a clock and the four-wheel drive indicator. It can be adjusted for different tyre sizes to give accurate ground speed when using sprayer or spreader attachments, or driving on the road.

Deere claims that engine braking has also been improved for hilly conditions. The vehicle’s descent control system allows the clutch to stay engaged, providing more controlled deceleration down to around 3mph.

The continuously variable transmission (CVT) intake now draws in 50% more air to reduce heat, as well as the amount of water ingested by the CVT system and the clutches. Deere claims that this leads to less belt slippage and improved durability.

The 25hp XUV 855D Gator has a top speed of 32mph (52kph).

The on-demand four-wheel drive is activated by a dash-mounted electronic switch.

The suspension can be adjusted at the rear. Ground clearance is 267mm (11in), total payload is 635kg and towing capacity is 680kg.

The Gator’s four post ROPS frame can be upgraded to a full glass cab.

Other options include tool carriers and cargo box dividers, a front mounted load rack, a bull bar and side extensions. A rear bumper and horn are now standard.

The prices for the new 2013 model John Deere XUV 855D 4x4 Gator utility vehicle starts at €14,385 or £12,227 in Northern Ireland, for the base machine fitted with standard seats and Terrahawk all-purpose tyres.

The power steering option adds €602 (£512 in Northern Ireland) to this model.
