Not necessarily. Clutches are built to hold a certain amount of torque, exceed that and it starts to slip. To hold more torque one could change the friction material to something that has a higher coefficient of friction. Increasing the average diameter of the friction area, not always possible. Increase the spring pressure, more pedal effort required. Increase the number of discs, think big trucks, JD two cylinders...
If for instance you increase the area, you have the same force applied from the pressure plate. You will have less psi on the friction material resulting in less holding power per puck, but since there are extras you end up at basically the same capacity with a disc that may wear longer. If we had all the numbers we could run the math and prove it out.

If it would just start when I turn the key, then I would use it more often. In addition to a bad case of old age, most of the tractor's original electrical system was simply too unreliable to keep.
