HCL Machine Works was established in 1947 by Walt Hansen, Archie Clayhold and Hans Larsen. In the early years, HCL focused primarily on farm equipment repair and modifications. In 1973, the current owner, Sherrill Campbell took over the operation of HCL and for the better part of the next three decades Sherrill grew the business helping to add several products which are exclusive to HCL. HCL has repaired, developed and manufactured seed bed cappers and decappers, narrow row cotton picker kits, defoliation booms and other custom implements and equipment which are used in California’s Central Valley’s agricultural industry. In addition, HCL has developed several products which are exclusive to their brand. The LIV-POWR hydraulic system for crawler tractors was developed and patented and the HCL 10’ and 12’ Compost Turners were also added to the line of custom equipment.
