Just purchased a 93 brush bandit 90 with a Perkins 104-19 diesel motor. Was trying to find some literature or manuals on it with no such luck. Machine is in pretty good condition but having issues with starting it. I’m sure the glow plugs are bad but was wondering if there is any type of clutch or mechanism that is suppose to engage the chipping disc as the rpm’s increase? Right now it’s acting as direct drive and takes awhile to get it running. If anyone has some info, manuals, etc that would be a great help. Thanks
