OUCH

First of all was the jump tractor SM Neg ground which is my guess if it has an alternator???

REGARDLESS ALWAYS jump or charge Pos to Pos and Neg to Neg as posted below. Hope your alternator didnt get damaged????

Next, if youre trying to jump start a tractor LPM with no battery at all, tHE jumper battery SM basically replaces the LPM battery and you could attach the jumper cables to the battery cable ends OBSERVING CORRECT POLARITY

We recently covered how to jump start THE STARTER MOTOR ONLY while allowing the tractors battery to power the ignition if needed but since your LPM has no battery (and if needed if its NOT a Mag ignition) that dont work so you have to go the route of the paragraph above.

Another way to replace battery jump a tractor that has no battery (same as attaching to battery cable ends) is to attach one jumper cable to the Battery input (NOT to starter) side side of a starter switch or solenoid and the other jumper cable to case/frame/ground (observing correct polarity) That way if you turn on ignition and/or depress a start switch or solenoid key/switch activation its the same as if the dead non battery tractor has its own battery.
IF YOU HOOKED ONE JUMPER LEAD TO THE OUTPUT OF A START SWITCH OR SOLENOID AND THE OTHER TO THE STARTER POST THATS A DEAD SHORT AND VERY HAZARDOUS

If youre jumpimg a starter motor I always attach the FIRST lead to the starter post/stud or the output (to starter NOT to battery) side of a start switch or solenoid and make the LAST connection to a clean non painted part of the frame case of the tractor near the starter as its usualy easier to get a good bite to frame versus a starter stud and theres also less chance of a short if youre trying to jump to the starter post/stud when all is hot (cuz the ground was made first)

Hope this helps, post back any questions

DO NOT USE A 12 VOLT BATTERY TO JUMP RIGHT ON/TO A 6 VOLT BATTERY, THE 6 VOLT COULD POTENTIALLY BLOW UP
