I bet it is front right belt set bothering. Have him order a power band belt 71170679. A higher quality of the same belt is 71364514. Cheaper belt will do fine on that machine. We do this for all machines with double belt drive in corn and sunflowers. Stalks get up and knock the belt or belts off. No problem with power band where the two belts are bonded together. '90 and newer machines have a single C width belt and have no problems. Have your brother over and check out the hyper mod site. likely plenty of things he could do to wake up the machine. Good luck
