Well, we replaced the drive motor's burned stud, but Pete's tractor still doesn't go.
When shifted into forward, one of the big contactors clacks loudly over and over, but I can't tell which one of them is making the noise.
When shifted into reverse, the open-frame reverse relay behind the dash flips back and forth like a hummingbird's wing, buzzing loudly.
Does anybody know what might be the cause of this? The tractor's an E-15 model 26AE15DA.
