Clutch Clipping Technique

An important step you should take whenever you store or stop using your BCS tractor is to clip the clutch lever.


The reason for this is simple. The standard double-cone clutch used in most BCS tractors has two cones. One is connected to and powered by the engine. The other is connected to the transmission’s drive shaft. When you compress the clutch lever, it separates the two cones, creating an air gap between them. When you release the clutch lever, a very strong, heavy-duty spring compresses the cones together.


Please note: This information does not apply for PowerSafe tractor owners (models 739, 740/749 or 750). The PowerSafe clutch is based on a different design that what is described here.

If you leave the clutch lever released (un-clipped) when storing the tractor, the cones will be meshed together. Over a time, the cones can bond to each other due to moisture in the air. If this happens, the “stuck” clutch will make your BCS tractor inoperable, but this problem is entirely preventable.

To fix a stuck clutch requires removal of the engine/clutch assembly from the tractor transmission. Details on how to repair it are available in BCS service bulletin 2-6  (we can also perform the repair for you). Though it’s not considered a major repair, it’s much better to follow the simple step described below to prevent the problem from occurring.

Whenever you stop using your BCS equipment, even if you plan to use it again soon, form the habit of always clipping the clutch lever. This holds the clutch in the open position, with an air gap between the clutch cones. With an air gap between the cones, they cannot bond together, or become stuck. This simple step is one of the easiest and best preventative measures you can take for your BCS tractor.
