The push button is a low current device, less than 4 amps. It is used to energize the starter relay. (That little film can sized device on the side of the starter) if it is smoking at that push button, there are two possibilities. One is that the button is going bad, or has a bad connection on one of its terminals. Or two the starter relay is going bad and causing heavier current in the button than intended. Easy checks to make: Using a piece of 10ga copper wire about a foot long, (with the tractor in Neutral and brakes on!!!) jump between the relay post connected to the battery, and the small terminal on the relay near it. It will spark a little, but if the relay is good the tractor engine will begin to turn over. (don't connect the 2 big terminals together with that small wire! it will get way hot and melt!) If the tractor spins well the push button needs to be either replaced new switches can be poor quality, or the terminals on it need to be cleaned/tightened and shrink taped to seal out moisture. If the tractor spins, but slowly, the cables might be incorrect size. They need to be 0gauge wires. These wires are about 3/8" of fine stranded copper with soldered on terminals. Typically prior owners use automotive cables of 4 gauge or so that are way too small. 6v systems use twice the amps of a 12v system and must have thick cables. If the relay seems to not work well, or requires more than one attempt to engage the starter (series of clicks) replace it. Be sure to connect the new one with the same connection locations. Using 10-40 or 10-30 oil in it will also help in cool/cold weather. Jim
