The range of gearboxes manufactured by CMR Group is divided into 5 series:

  • L series: with die cast aluminium housing for those applications that do not require very rigid reducer housing and power up to 25
  • T series: with G25 or GS400 nodular cast iron housing, for applications that require rigid with transmissible power from 5HP up to 300HP, for almost all agricultural uses.
  • V series: with G25 cast iron housing, with transmissible powers from 20HP up to 100HP, exclusively for the vertical-axis lawn mower and brush cutters.
  • S series: with GS400 nodular cast iron, with helical bevel gears, designed for the rotary rakes sector for hay making and picking up branches-pruned material (pruning rakes).
  • E series: with GS400 nodular cast iron, exclusively with helical bevel gears, designed for harrows.
