No apologies about mechanical knowledge needed, but around here be ready to learn cause there is a wealth of info on this board.

Nat has good info but I’d like to add that the battery here could also be weak or failing. It might have enough juice left to power the coil and provide spark but not enough to roll the engine over.

Is that W-4 still factory 6-volt positive ground or has it been converted to 12-volt (usually negative ground)? A quick way to tell is by using a volt meter. If you don’t have one handy, normally the 6-volt battery will have three caps on the top that will come off for adding distilled water to the battery. Most 12-volt batteries have two large plastic caps that come off for the same purpose but will cover three openings each.

If it has been converted to 12-volts, you can try using booster (or jumper) cables to start the tractor. Always, I repeat always remember when connecting booster cables to connect them to the batteries positive (+) to positive and negative (-) to negative. It is also preferable to make the last connection of the cables to a metal ground away from the battery on the dead battery vehicle. Crossing them will produce sparks and increase the risk of explosion.

Most important if you don’t know, ask. Even if you think it might be a “stupid” question someone here will give you a good respectful answer back.
