[AT] cracked head

[Louis]

We had a John Deere 850, that cracked a head.  I had it repaired by a real
good machine shop.  They used the stitch and lock method.  The owner of the
shop wasn't real sure if it would hold up.  He didn't charge me, until we
knew if it would hold.  I put the head back on the tractor.  It cracked
again within a half hour of running.  I got a bare head from Deere and had
the machine shop move all the parts that needed to be installed on the new
head.  I would say it is a crap shoot to repair heads on those tractors.

An automotive machine shop should be able to fix the head.
