mn | I don't think you did too bad on it. The first thing I noticed is it does need all new chains. They are original judging by the fact they have factory paint on them and they are quite stretched out. Use American made chain and use Slip-plate chain lube.
There are a few hidden grease zerts on them so try to find an owners manual if you didn't get one.
The sledge gears are OK. I just looked at the idlers and there is quite a bit of wear to them. If you look at the side of the gear closest to the roller you can see what they look like when they are new. I just put them in one of my balers and it was around $1600 for the gears and bearings for both ends of the rollers.
If you break a splice on a belt switch to the Alligator splices. They are available at Miller-Sellner and the tool is about $150. The splices NH uses are crap.
My bars on my rollers are square (mine is a 664 tho) If it stars spitting hay up in front of the belts by the net knife it needs new bars on there. I just got some stock and welded it on. Also something I tried for the first time this year was putting bedliner on the dimpled rollers, works awesome! It works best to run the tractor wide open and feed it fast to get the bale started. The only time starting a bale is a problem is in road ditch hay that is all laying lengthways in the windrow.
The knife can be sharpened, ive never replaced one. Since changing to the Pritchett wrap I haven't touched my knife. The key is to make sure the rubber on the net brake is good and make sure the brake is only released when the duckbill is fully extended. Also make sure the knife drops freely. I put a chunk of iron on mine for weight. Mine will cut the wrap regardless of speed.
Hope this helps.
Don't get discouraged if you have problems. The first year or I had my first one it was a lot of problems. (it had a lot of bales on it) But now after learning how everything works and adjusting things right it works perfectly.
Hope this helps. | |
