Baler knife

ron 861 · Jan 10, 2013

I recently purchased a New Holland 275 baler,noticed the lower couple of inches on the knife edge is beat up, looks like may have come in contact with some metal. Question is,should I try to sharpen it with a 4" grinder or replace it. Eather way it doesn"t look easy to get at.
Thanks

Sharpened lots with a grinder.Yes they can be a PIA to get out.Dont worry about getting every notch/divot out.there a lot of balers out there running with a notch on the blade.Mine is one of them....

Like Delta, I typically just sharpen them in place using either a 4 1/2" angle grinder or sometimes a small die grinder with a stone or sand roll when space is really really tight.

I do the same on mowers and bushogs and do not try to grind back far enough to remove all the divots as that often removes way to much metal for my liking. I will lightly grind the back edge so that it is flat again around any divot deformations. Then I simply lay an edge on the tapererd part to make it sharp again. The divots are just as sharp as everywhere else that way.

If you do remove the knife for sharpening, make sure you keep track of all the shims behind the knife as that gap must be set properly. Also it might be a good idea to verify that the plunger bearings are not getting excessively loose causing the knife to hit the baler shear edge which could be the source of your metal to metal contact. Proper adjustment of the existing bearings or replacement with new bearings along then with proper adjustment of the plunger bearings to spec will fix that issue.

If you take them out, be careful getting them back in when they are real sharp.

Try to sharpen it first, ONLY on the feed side. If you can't get it sharp or have to replace it, try Wengers or Esch parts in Mt Joy, pa. Esch manufactures new aftermarket, as does Fry Equipment in upstate Pa., and a 1/3rd of the new cost....

Another thing that can happen is a finger comes loose.Been there done that.Shimes are very important.they need to be close.Good Luck.

Be sure to check your rails and plunger bearings are tight and set to spec. I'd have to see the knife, to tell you what I think, but yes, they can be sharpened. Don't really need fancy equipment, either, a 7 or ( inch angle grinder, or a big bench grinder. Match the existing angle, and go slow, and don't burn it, quench often, don't let the metal get blue.

Make sure bearings are good and set up properly. Clearance on the plunger knife should be .010-.030 at any point that they cross. Shim accordingly.

My old IH model 46 has reversible blade. I need to adjust it closer as I occasionally get bales "hooked together".
Edit: Now that I think of it may be the stationary edge.

Esh hay equipment is in gordonville. But they are a very good baler shop. Probably better than most new holland dealers.
