I crank started my Super C for the first year I owned it without any issues as the charging system was totally wrecked in every mode. If done correctly it isn't an issue. If it is still an original 6 volt positive ground tractor you really need to make sure everything that is related to the starting and charging circuits are shinney clean and bright at every connection. Also, I use 00 size cable with soldered terminals for the battery cables on all my 6 volt tractors. The factory ground which is in the battery box using the instrument panel base is poor at best as it passes through a lot of chassis before reaching the starter. For a test run a good size cable to one of the starter to frame mounting bolts for the positive ground connection. I have found the battery voltage needs to be 6.2 - 6.3 generally for easy starting. Anything less just doesn't seem to work well. A weak or battery with just a couple years of age can certainly be suspect if it can't be totally charged. Your other components like the generator and voltage regulator are for charging the battery and a fully charged battery should start your tractor regardless of their condition. I recently found the push-pull switch a culprit on a 140 as too it's starting issues. Check the voltage coming out of that switch on the coil side as it should be the same as the battery voltage and if not you don't have enough current to excite the ignition components. Your thoughts on the starter switch are good but again everything needs to be shinney bright and clean. You might take the starter and have it tested also to eliminate it as being defective. NAPA or other good auto parts store generally test them free of charge. Good luck and post back your findings, Hal.

Today's Featured Article - A Lifetime of David Brown - by Samuel Kennedy. I was born in 1950 and reared on my family’s 100 acre farm. It was a fairly typical Northern Ireland farm where the main enterprise was dairying but some pigs, poultry and sheep were also kept. Potatoes were grown for sale and oats were grown to be used for cattle and horse feeding. Up to about 1958 the dairy cows were fed hay with some turnips and after that grass silage was the main winter feed. That same year was the last in which flax was grown on the farm. Flax provided the fibre which w
