For even greater versatility, efficiency and practicality, Dorado Natural tractors are offered with a choice of two transmission configurations. The standard variant is based on a 5 speed gearbox with 3 ranges and a reverse shuttle (for a total of 15+15 speeds), allowing the tractor to work at a ground speed of just 298 m/h at maximum engine speed in the lowest ratio available, and - at the other end of the spectrum (with overspeed) - permitting a top speed of 40 km/h at just 1,800 rpm (with 420/70 R30 tyres). An optional splitter, controlled from a lever situated conveniently under the steering wheel, doubles the number of forward speeds, increasing the total number of ratios available to 30+15. Other standard features on Dorado Natural tractors are electrohydraulically engaged all-wheel drive and front and rear differential locks.
