Case/International 8420

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.
 
If it's the baler I'm thinking it is there is a funky little rod up near the gauge that vibrates against the unit creating a loud "rattle" to let you know to tie.
 
Well. Lol. That explains that. I
just got everything wired up and
adjusted for the twine cutter
and greased and oiled
everything. Figuring out how
everything works. Pretty simple
machine but for the life of me
couldn't figure out, what I
thought was a worn sprocket, on
the end of one of the rollers
was for, and then the funny
looking metal rod that seemed to
do nothing sticking back through
the machine. Now I know. Thanks
for clarifying that. I can sleep
better. Lol. Does anyone know
what proper twine to run in this
thing? It has 3 brand new rolls
of polypropylene twine in it
now. My square baler always used
9000 foot sisal. Seen 16000 foot
sisal for round balers and 20000
foot polypropylene.
 
Choice of twine depends on end use. If they are to sit outside for very long poly is the way to go (20K is fine), if you're storing inside and/or would rather not use plastic, use the sisal; the baler really doesn't care.
 
Thanks for the help Jaoneill. Greatly appreciated. Rain for two days then a stretch of slight chance. Hoping to get to try this thing. Bales will be sitting out, so I think I'm going to just use all three rolls of poly. Thanks again.
 
I have a 8420 and maintain a couple of 530 Hesstons (same Baler). All of the switch boxes I have seen have a hole with a fuse holder in it. My 8420 had a manual tie, but I added my own electric threader and built my own switch box.

They are good simple balers. The sprocket should engage the 'rattle rod' as an indication of nearing over full, not the regular bale full indication. Use the vertical gauge for that.

I guess that I would stand corrected on the rattle rod.

To be honest, I've never owned one of those balers but have helped the neighbor, and also my brother, both of whom have those machines, both of whom instructed me to simply listen for the rattle rod. As it turns out, as I remember, it and the gauge are pretty well in sync anyway. Generally is best to read the manual for the "proper" operating instructions.
 
I have an 8430 and it will run either one but it needs 16000 foot balls of twine. 9,000 is for square balers and the rounds do not need that big of twine on them. Sisal will rot if on the ground for a while and the plastic twine won't. I drop hay bales in the bale ring for the horses and they never eat the twine but it rots up by the time I haul manure. I guess I should remove it before putting it in there but 10 years no problems. I never hear the rattle rod in the cab of the tractor but what the other posters have told you is correct. Also check the little connectors that hold your belts together every day before baling. I didn't and had a couple belts come apart because of it, now I check them. You've bought a good baler. just my thoughts, keith
