Bob, an ammeter (direct) is a passive series pass through current measuring device REGARDLESS if the current is on a tractor or Hummer or Bulldozer.........An "ideal" ammeter has ZERO ohms of internal resistance so even a cheap direct series meter meter will have extreme low internal resistance.
HOWEVER the range and resolution is another whole matter. For instance, the range for an old generator equipped tractor may be + 20 to - 20 or + 30 to - 30 etc., while if on a later model car or tractor with an alternator it may be 60 to 60 or even 100 to 100 AND THATS NOT AS ACCURATE OR AS EASY TO READ if youre operaitng in the 20 or 30 amps range.
Sooooooo basically an ammeter is an ammeter REGARDLESS if on a tractor or auto or a widget but the scale and range may be quite different. If an old tractor its likely 20 or 30 amp so if you buy an automotive unit it may be 60 or 100
