I have a yellow colored 380 Case David Brown tractor in the shop. The shift lever would not hold in the forward position. I split the tractor and found that the forward drive gear and shifting collar in the synchronizer are worn out. I am trying to order new parts for this tractor. I have contacted my local case dealer and they cant find a 380 in the parts book. The hood on this tractor says 380. I looked under a 380CK parts book and the parts look similar. I am woundering if thats what i have. any David Brown experts out there that can help me determine what this is, or where to find the parts i need.
