JD 467 baler surface wrap problem

Tx Jim

Well-known Member
Every once in a while my JD '05 467 rd baler with 23,000+ bales on monitor will eject a bale with no to very small amount of surface wrap on the bale. My baler operator states no visual or audible alerts are
seen on monitor screen. I'm stumped as to what to do to solve the problem because an alarm should appear on monitor screen.
Thanks for any ideas.Jim
 

I'm glad to find out it's not just my baler that's malfunctioning. I don't understand how monitor can give the signal bale is wrapped and to eject the bale when the wrap doesn't put enough pressure on linkage that is designed to trip switch to notify operator that wrap is cut when wrapping is completed. My adds unwrapped bales to bale count on monitor also which also baffles me. I wonder if surface wrap drive belt is slipping sometimes not turning wrap feed rollers enough to apply 2 wraps of net? I can't remember ever replacing my surface wrap belt on current baler.
 
Seems I only have trouble with that when I am baling for someone else or no loader around to unroll it so I can rebale. What kind of wrap do you use?
 

Ambraco Edge to Edge. I've been unrolling rd bales without the aid of a frt end loader for yrs. I just place my tractor frt tire against unwrapped bale in the opposite direction bale was rolled and gently unroll bale without ever getting off tractor. Last 3 bales I unrolled with my pickup Ranch-hand frt bumper.

Yrs ago when I ran an experimental spiral rod starter roll for JD I demonstrated to JD engineer from Ottumwa how I unrolled rd bales and he was amazed. He stated he had been unrolling them for yrs by HAND :wink:
 
Any chance your operator is just dropping the RPM's while it's wrapping? My wife started baling hay this year, and had some bales with little to no netwrap on them. Always on the end of the fields. Turns out she was idling down to turn on the ends while it was wrapping. Fewer RPM's means less wraps. Once she figured how it worked, didn't have anymore problems.

Jim, Ambraco has a really good video on edgewrap balers on u tube- it's about 3 hours long and I believe the tech covers that. They were using a 459, but the 7-8-9 are similiar....

Thanks for asking. Since I have permanent since '96 I have to rely on friends/neighbors to operate my baler. I'm observing what's happening while they are baling and my hay baler operators get offensive when I quiz them about not watching monitor but NO they're not lowering engine rpm's.

Thanks for reply. I will watch the video you referred to.

TXJim: I would check the top roll on the baler. Many times when there is little to no mesh on the bale but the monitor is not issuing any warnings the mesh wrap attachment is dispensing wrap. It is getting wrapped up on the top roll where the mesh has to go from one set of belt to the other. Then the mesh will come off the roll while your making the next bale. The next time you have a bale with little to now wrap on it have the operator stop and check the top roll. I have had this happen clear back to the 35 series balers. With them you did not know if the mesh wrap had been applied or not. With any of the balers newer than the 66 series the monitor usually will catch the mesh wrap attachment not applying wrap.

What I have on all three balers now is a closed circuit camera that looks back into the baler at drawbar height. We glance at it when the bale is being wrapped. You can see the bale inside the chamber. If there is not enough mesh on it the bale will still drop down into the open area between the starter rolls. When the bale has enough mesh on it the bale will hole its shape and you can see that looking in the front. You soon can learn to tell if there is wrap on or not. We bale 75% shredded corn stalks. You do not get to unroll that bale to rebale it with stalks. You get a PILE that is about impossible to rebale without a loader to scatter it back out.

The system we use has two cameras. So we also have one looking behind the baler too for backing up and to make sure the bale has not rolled back under the end gate before you shut the gate/door. The system cost about $900 total.

Thank you. In the past when no wrap was on the bale I checked all rollers for wrap but found none or very small amount but I will certainly check top roller next time it happens. Over the yrs I've had wrap get on top roller that I've had to remove BUT I was unaware wrap can get on top roller then disappear from roller on the very next bale made.

Other than snags on belts & poor(broken) lacings are there any other causes for wrap to miss bale & wrap a belt roller. I understand problems that mud on starter roll can create.

I also understand the need for FEL to unroll mis-wrapped Corn or Milo stalks as I've baled more of those than I really wanted to. :wink:

I forgot to mention I've considered installing cameras and now think that will be one of my Winter projects. What brand/model camera did you install?
Thanks,Jim
 
I watched the video that Donjr recommended and sure did see good ideas on what I need to look at.

I agree that the video is very informative for JD rd baler owner &/or operators

TxJim One of the reasons the top roll will wrap is a dull knife or anything causing a ragged cut which can leave long "tails" on the cut edge of the mesh. So when you start wrapping the bale the mesh is shot across the gap between the top rolls. Some of the tails go over the roll while others go under the roll. The belt tension of the roll will grab the tails and catch them together causing them to start to wrap the top roll. If the belts are good and tight the mesh will not be wrapped tight. So many times will pull lose while your building the nest bale. It usually is pulled off during the starting of the next bale.

Thanks for reply. I do see a few tails hanging from the cut off wrap. I watched the Ambraco U-tube video that donjr referred to and narrator discussed tails & knife. Narrator stated not to sharpen knife but to replace it instead($266). Have you ever attempted to sharpen the knife? Thanks,Jim

Jim I sharpen mine all of the time. I use a small air driven belt sander and fine sanding belts. If the edge is still good but just dull I use 600 grit. If there are knicks I start with 400 grit and work my way down.

Thanks for showing photo of air sander. Approximately how many bales do you bale between sharpening the knife?

I asked my neighbor that purchased a new 469 about a month ago if he saw any net strings hanging on the rear of his new baler after baling a few 100 bales and he stated yes he did see some strings hanging down.
Thanks,Jim
 
Jim there will always be some tails. You do not want real long tails or too many. This is what will cause the trouble. The real long tails will also wrap the roll bearings worse too. Some types of mesh wrap make more or less tails too. It depends on the weave of the mesh. The Ambraco generic wrap can be tougher to cut and you will need to keep you knife in good shape to work well with it.

As for how many bales between sharpening the knife??? I usually just sharpen them in the winter when going over the baler. So that can easily be 8-10K bales. The knives are hard and usually do not dull that much.

Also check the tension on the mesh wrap IF it rolls too easy the cut will be more ragged too. I have had to replace the spring on the drag roll/bar too.
 
It is the bar or roller than holds the mesh roll to the front of the mesh box. It causes some tension to be put on the roll of mesh wrap. The roll tends to turn harder at the beginning than the end as the smaller roll turns easier.

I'm unaware of the spring you referred to but are you referring to the gas operated cylinders? Yes I was aware resistance placed on roll of net is less as net roll gets smaller because rear cover gets easier to close as net roll gets smaller.
Thanks,Jim
 
The yes the gas struts or shocks. The mesh tensions can be too loose it the mesh roll can "coast" after making the bale.
 

My net door is fairly challenging for me to close after a new roll is installed probably due to my nerve damage & lose of physical strength so I think my balers gas filled cylinders are fine.
