I understand the relationship of higher cranking-voltage equating to faster cranking RPM. I am also privy to the concept of a diesel starting better when cranking faster. My point was and still is . . . you mentioned a minimum of 11 volts. 11 volts (or higher) at cranking is very difficult to achieve in a 12 volt system and that is why 12 volt starter motors are designed to work well down to 9.5 volts. It's also why batteries are typically load-tested at 9.5 volts, not 11 volts.
A typical brand new tractor will crank at 10-10.5 volts in warm weather and 9.5 - 10 volts in cold weather. Getting over 11 volts at cranking would be very difficult and require a huge set of batteries and cables - even in warm weather. And considering a battery loses near half it's cranking capacity at zero F, it would be even more difficult in cold weather.

Today's Featured Article - Massey Ferguson 35 (and up) Tractor Assembly Notes - by Jack Wetmore. These assembly notes are for Massey Ferguson tractors with a two stage clutch and 6 speed, 8 speed and mutli-power transmissions. I see a lot of discussion forum messages regarding damaged clutches from improper assembly. The objective is to have the engine and transmission slide together safely and easily until the gap between the two halves is less than 1/4", BEFORE tightening any of the bolts holding the two together. Using bolts to draw the two halves together will damage the PTO
