NH 273 good baler for small operation

Just bought a 273 NH baler. It seems tight. Has not baler for about five years. I intend to clean it out and grease it up. Any thing special I should check.
 
Make sure the twine knife's are good an sharp. Dull knife's will cause major problems
 

On balers that have sat for a while... I would try to get some penetrating oil on the rollers on the sides of the plunger. If you hear squealing or squeeking from the plunger, these rollers may be frozen

I would also ensure that the plunger stop mechanism moves freely.

Check all of the grease fittings on the knotters, to make sure they take grease.

Another set of greased joints that can dry out are the joints on the needle activating arm

Check all the belts for dry rot.

Make sure you grease the plunger where the drive arm connects to it.
 

I would also check the big aluminum "dinosaur teeth" behind the pickup. They rake the hay across to the chamber. I always just remove one or two and take them to a dealer... then ask to see a new one.

With a couple of old balers that I brought out of mothballs, the previous owner had worn them down to about half of their original size.
 
Forgot this but the #1 thing to make 1000% sure work is the plunger safety stop. If it doesn't work as it should it can cost you the whole baler
 
First thing is get a manual. You're gonna have all winter to clean it up and check it out. After you get it clean make sure the needles are in home position and turn it over by hand to make sure it's not froze up. If it's sit dirty for 5 years it's hard to say what you might find. Good Luck.
 
Open the top of the baler and be sure the feeder mechanism is operating freely, clean it out and grease it.
Be sure the needle safety stop is free and adjusted properly.
Roll it over by hand to be sure it is not binding.
Trip the knotters when rolling it by hand and look for freedom of movement.
The plunger is likely moving on rusted rails, oil it and the rust will go away as you bale.
Plunger bearings might need to be freed-up
Is the pickup moving freely?

All fairly easy to check BEFORE you put the power to it.
 
Check all the feed fingers for length. Mine was making banana bales till I figured out they were worn. Check the parts list for lengths and position. Three new finger fixed the problem. If they're short, DON'T try to move them down too much or they'll fall out, happened to me. Also get a few extra springs that pull the fingers down. They stretch and snap back with each stroke so they don't last long. Check the six carriage bearings, too. The lower guide should be adjusted to 1/32 vertical clearance and it will make less noise. Get a manual and if you check the timing go in sequence. BTW, the shear bolt on the knotter shaft is a #12.
 
Thanks for the tips. I have the baler home after a forty mile tow. I have a manual. It was a one owner and he switched to round balers a few years after he bought it.
 
my two cents.. Id blow it off with air and grease it.. THEN turn BY HAND over couple times see if anything locks up..initiate the needle latch to see if needles run through smooth.. ALL BY HAND.. see if anything binds or locks up or sticks etc. Id do this multiple times..AS OLD said make sure that plunger stop on the bottom is working and greased ad that will save you $$$$ keeping that in good shape..

Id hook to pto and engage in slow..like 1500 and let it run actuating those needles etc multiple times. If ran smooth by hand then pto shouldnt be problem..

then go from there.. meaning alittle hay see if it ties...etc...etc..

If it doesnt tie go to the manual and start at the beginning taking EACH STEP in order and re set everything to the books standards IN ORDER... then should work.
 
OOOOPPss almost forgot..
MAKE SURE slip clutches are in good working order.. manual will tell you how to check..
