OK more gear motor problems!
 

OK I keep killing gear motors, so I got these 90' motors they kind of worked till theyou get hot.
Now I am at the point where I'm over this dozer! What I'm looking for is something with 100-150 rpm but with enough power to push dirt easy and it need to be small. Not to long or crazy pricey new car payments and all. Any ideas? What have you guys used in the pass?
