I have a suffolk punch 14sk which starts runs and cuts excellently the only problem is that on starting the cutter blades revolve all the time and will not stop even on slow idle speed. What is the mechanism that disengages the cutter cylinder and would a larger and looser drive belt help
NO dont change the belt, chances are its just the cable needs adjusting, slacken the 10mm nut on the adjuster that goes into the casing on the left side of the machine ( think its the top cable that adjusts the cylinder) after the nut is slackened off turn the adjuster clockwise so its going into the casing,you can do this while engine s running. the cylinder should stop turning as you wind in the adjuster. I would also suggest that the cylinder is turning too easily and it will need adjusting by turning the adjuster screws either side of the cylinder. turn the adjuster screws clockwise one click each at a time until the cylinder just touches the bottom blade when you spinn the cylinder by hand( with the engine NOT running!!!!!)
