Simon Wales, technician at Ernest Doe’s Big Baler Centre, Marlesford, Suffolk, guides Andrew Pearce through the second installment of our New Holland BB baler service ILast month we covered part of a pre-season service on a NH 9070 big baler. Now we finish the job, and, as before, the plan is not to trundle through the operator’s handbook. While this is a treasure trove of info and a vital reference, here the idea is to draw on the experience of a specialist to highlight specific areas that BB owners or operators should look at before the season starts. We covered the pick-up, the right-hand side of the machine and the bale chamber last time. Now we turn to the shearbolts, move along the left-hand side, delve into the packer and stuffer, and go through the knotters.
