Some Preventative maintenance on the 1431, trying to avoid another costly repair on the discbine. I lost a #9 module bearing on Sunday Afternoon last week , which really brought the haymowing to a halt. I am attempting to get grease in the upper module bearings after noticing the new modules came with a grease-filled bearing.... Apparently the upper module bearings don't get any lube from the lower module reservoir. Also, this is a good time to remove the twine that was built up under the upper module. I mowed about 250 acres without incident before the bearing failure.
