It depends on how much torque has to be transmitted, and how much the clutch has to slip. If you manoeuvre around to get between things when you are cutting, especially if you are on a slope, the clutch tends to take a beating. Cork clutches are not good for that kind of service, they tend to be "in or out" clutches. Also, the amount of torque you can transmit through a clutch depends on how much clamping pressure you have - and cork can't stand high clamping pressures. Generally cork is for very light duty clutches that are not used for controlled starts. I don't think it is suitable for this job.
