I took my jumper cables, connected my car battery negative,

the last negative lead and placed on a ground source on the
tractor, it sparked and produced a puff of smoke. I
immediately removed the cables and believe it or not, I
then tried to start the tractor, and it started.

You are damn lucky the battery did not explode.

Why? Did I do something wrong? I followed basic jump start procedure. Is
there something in the steps above I did wrong? I'd like to know for future
reference. By the way, the car was already on and running for a few minutes
before I hooked up the cables. You're supposed to do that, not connect
cables then start the car with the good battery.

By the way, 24 hours later, the tractor started right up.
