The newest Pro-Flex 120B incorporates maintenance free blade spindles and rubber-damped automatic belt tensioners which eliminates a significant amount of time needed for routine maintenance while also lowering operating costs. Progressive’s exclusive Pro Lift-N-Turn™ and Automatic Wing Cylinder Lock Valve make the Pro-Flex 120B simpler to operate than ever before!
Starting at S/N 15272165B, the wing hydraulic circuit includes an automatic lock valve to prevent unwanted movement of the wings during mowing. The new automatic lock valve is incorporated into the wing lock release mechanism (circled in the photo below). It replaces the manual ¼ turn valve that is found on earlier models. This change also simplifies the connection to the tractor as only two hydraulic hoses are required to run between the tractor and the mower. When the wings need to be raised or lowered, the Operator simply pulls and holds the pull rope from the tractor’s seat until they are fully raised or lowered.
The Automatic Wing Cylinder Lock Valve is truly an Operator convenience feature, and best of all the functionality of Pro Lift-N-Turn feature remains unchanged. The new Automatic Wing Cylinder Lock Valve makes operating the Pro-Flex 120B easier than ever before!
