On the starter motor, there is a stud with a cable attached. (assuming it has a push button (big) starter switch, not a pull rod)
Attach the jumping battery ground to the tractor ground (polarity does not matter) turn on the tractors ignition.
Firmly contact the starter connection on the starter with the side of the jumper cable gripper. It will spark seriously and spin the engine.
Because the tractor battery is not being used to crank, and because the jumping battery is not being used to make spark, and because these starter motors do not spin backwards, no matter the polarity. If it has some juice in the on board battery, or a mag ignition, it will start.
Do not do this at the battery, or connected to the starter switch. Also be sure it is in neutral!! and the wheels blocked/brakes set. Jim

Do as Jim said except make the connection on the starter stud first to get a solid non sparking connection. A loose connection can heat up the stud and loosen the soldered connection inside. Also you can damage the threads on the stud. Make the last connection on a clean ground.
