This trailed combine harvester was developed and intended for the needs of the small family farm and was available in a number of different configurations, for instance with a grain tank or a grain tank in combination with a sack-filler. The harvester was also available with a wide range of extra equipment such as a straw baler, straw cutter, pickup reel, torpedo straw divider, revolving extra straw divider, a mechanism to lift and separate the ears of grain when harvesting and a pick-up mechanism for row-crops such as rapeseed.
The production of trailed harvesters at Bolinder-Munktell ended in 1965, the last ones originating from Arvika Thermenius. The S 500 belongs to the last generation of towed genuine BM-harvesters. The harvester on display here has production serial number 25 738 and it was built in 1963.
