Well I ended up with a really nice 8420. Small bales but should suit me fine. It's been sitting for a couple years and I have everything moving and working. Belts look brand new. Electric tie wiring was chewed on but I got it working. Weather isn't cooperating right now but that's ok. I need a few more days to get ready. My question right now is that the baler had a box with a toggle wired up to put on the tractor for the electric tie. The box also had another hole in it and a plastic bezzle and nothing else. Is that a spot for a full bale alarm or a full bale light? I don't see anything on the baler itself other than the sliding bale gauge that would even set off a light or alarm. Anyway to set one up if it's possible. Thanks.
