The Boxer was a 50 horse tractor that could handle most jobs on the farm, thanks to its wide range of gear ratios, its smooth sides and good ground clearance made it well suited for forest use. This cutaway exhibit shows all the details that made the Boxer so succesfull. 


The Boxer is one of the tractors that played a major part in the history of BM tractors. Thanks to its sturdy chassis, this succesful tractor formed the basis of new products in the forestry and construction machine sectors and paved the way for BM's construction machines. The DR 631 articulated hauler and the LM 218 wheel loader are exhamples of construction machines that use the Boxer as a basic chassi. Both can be seen here at the Munktell Museum. The Boxer had clutched and direct-drive power take-offs as standard. Many Boxers were used by the Swedish armed forces to tow power-axle trailers- a combination with excellent off-road capability. In total 28 439 units were produced, including the industrial version and PKD kits.
