I don't know that I buy that. While the engine may start easier, I think there would still be a tell. If the starter used more amps from the larger battery, those amps have to go some where. The engine takes the same finite amount of power to start regardless of the condition of the starter. Any extra power consumed would be turned into heat. I think the starter would be smoking hot after turning over the engine for a short period. Just my "thoughts".
I do like the load tester in place of the starter for checking the wiring. For those of us without a load tester, would a second tractor suffice? Unhook the problem starter and connect the start cable to the starter post of another tractor with jumper cables and ground the two machines together. See if you can turn over the second tractor with the first. I think Todd is past this, but just more thinking out loud.
