Same Solar / Lamborghini 550-660 / Hürlimann H-351/361
The Solar represented the best basic tractor in the 50-60 hp class and was introduced in the summer of 1986. As a basic model, it was equipped with a rollover protective frame, and a rudimentary cabin was available at an extra cost. The 3-cylinder air-cooled engines belonged to Sampo's older model range. Similarly, the 12+3-speed gearbox (16+4 with crawler gears) also came from the generation preceding the Explorer. The Solar 60 had a rather high lifting capacity of 2970 kilograms. Solars came standard with oil-bath brakes, and the four-wheel-drive models featured hydrostatic steering.
With Lamborghini, the same model was known as the 550 and 660 models, and with Hürlimann as the H-351 and H-361. In the USA, the same tractor was sold under the name Agco Allis 4650/4660.
