BillVA and NH 68 questions

Hi,

In a recent post you talked about your 68 making solid bricks of hay. We are going to plant a small field of alfalfa next year and I want to work on our 68 this winter to get it better at making sale-able hay bales. This baler almost never misses a tie and has been really reliable for us overall.

The bales now are frequently inconsistent in length, and the cut edge is ragged. I am sure that I need to replace the wood runners and work on getting the knife edge to be more precise to clean up the side of the bale. Quite a bit of wobble there. Also the ends are rounded, not brick square like I see on bales being sold at the auction.

Anything else you suggest to get the baler to produce higher quality bales? I did replace the small inner knurled spacer that the length sensing arm rides on but it did not seem to clean up the variable length problem much.

Any help or pointers would be appreciated.

The key to consistent length bales is 2-3 inch flakes per plunger stroke. One of the things we did was slow the ground speed and
run the baler at full 540 PTO rpms to get more flakes.

For your ragged edge, a sharp knife within about 1/32 inch of the stationary will really help - as will smaller flakes as there is less
thickness to shear.

Search this site - when I went through our baler, I purposely used NH68 vs New Holland 68 or NH 68 to help with searches on my
baler.

Feed the baler to the plunger side of the pick-up, make sure your aluminum feeder tines are about 13-3/4 inch long. They wear
down over time several inches and if they are not the right length, you can never get enough hay into the bale chamber to prevent
a banana bale.

Though the JD348 has taken over primary baling duty on our place, there's a good chance the NH68 will be used for some 2nd
cutting very soon.

Good luck,

Inconsistent bale length can often be caused by the teeth on the metering wheel assy wearing out. I recut the teeth on the arm on my 68 with a threading file and pretty much solved that problem.

Ragged edges are a dull knife or shear plate or too much clearance. The shear plate can be shimmed from outside, 3 bolts ahead of the needle bale on the right side looking forward.

The knife can be sharpened with a 4" grinder while on the plunger, but if you're going to check the slides, do it while it's out.
 
Be careful shimming the shear plate do
not shim it pass the slide that is in
front of it at the bottom so the
plunger knifr wont hit the shear plate
and it be bye bye baler
