I have 8N hybrid.
Model number 8N144620 with a Ferguson TO20 top plate linkage and hydraulic pump.
The top plate casting is broken so I found a 8N top plate and atempted to instal 8N top plate and determind the one on my 8N is not the same as the 8N top plate.
With lots of research my 8N has Ferguson TO20 top plate.
Is this common.
