You could also remove the top caps from the mower motors and install a 
shunt on one leg, reading with a generic VOM Meter.

Most clamp-on meters are AC, but they make AC/DC clamp-ons too. They use 
a hall effect probe and are very accurate though you need to set the 
zero periodically (like old-time ohmmeters). They are also considerably 
more expensive than AC only meters - $80+ (even on ebay). But very 
handy....
