Claas 255rc round baler net not feeding.

[Red Fred]

I am just getting the baler fired up for some silage, but the wrap doesn't seem to feed at the start of the bale. The control box appears to be fine and has been checked over by Mr King when he put a new plug on it, and the belts appear tight on the drive. I see it has a magnetic clutch drive, so I was wondering if there is anything to look at in there, if anyone has ever had a similar issue. I'm guessing it should click if I connect it up to a feed. Any suggestions gratefully received

 

[Pistonbroke]

Is the rubber roller turning when it's supposed to be?

 

[Bramble]

Rubber roller should turn freely, if not the bar behind might to tight on the roller. Magnetic clutch should either work or not, same as an aircon clutch

I have had a similar experience this weekend with an older Claas baler. It was fine for about five hours, but then would not feed the net in. Press the net button and sit and watch the knife trip quadrant travelling upwards whilst no net was being applied. At the last moment it would pull the net in, barely one revolution of net applied The roll of net was nearly empty, net roll tensioning clamp on or off it would not feed the net in as it had done all day. The next day I tried a new roll of net, no difference. I rethreaded the net, dropping a knotted lump through the feed in roller and leaving five or six feet of loose net, made a bale, pressed the net button and it worked. I made another bale, pressed the button and again no net was applied.

I then spoke to someone who works for Claas and his advice was, [1] make sure the roll of net was free to turn in the net tray, [2] try rethreading the net through less bars before the spreader bar. It then rained so I have not tried [2] yet. Not much help, but I am interested to hear any solution you find, Angus.

Shine up all the surfaces that the net runs over with some wire wool or fine sandpaper, that's the bars and the spreader and the tension bar against the roll of net. Make sure the metal roller that pinches the net against the rubber one is running free and tensioned. Also make sure the slot the net goes down through into the chamber is clear of chaff.

Will do @Pistonbroke, thank you Angus.

I have a 354 so maybe different,but there's an ecu on the right hand side with two multiplugs. I got water in the cable with a pressure washer and it stopped it netting. Wd40 and airline to dry it out cured it. Need to know if the rubber net roller is driving when trying to net to narrow it down

I connected a wire direct to that clutch to a switch in the cab and threw the control box away

The knife wuadrant wont move if there is no net going on.
Once the roll of net gets smaller you have to increase the tension on the net or it just slips on the rubber roller

 

[Red Fred]

Thanks for the help! I'll have a look tomorrow and see just what it is doing when I put it back on the big tractor in daylight. I find it is more of an art than a science to get the tension just right after loading a new roll and it needs adjusting with the bars as the roll gets smaller.

The quadrant rises when the roller is turning. Doesn't mean the net is going in. If the rollers and bars are clean and healthy the net tension doesn't need adjustment

Check the tension on the metal roller against the rubber one so it grips the net

Thats not been my experience

There's something else causing friction or there's a lack of grip on the rubber roller

Thats what i used to think, but it is all down to slack net when the roll gets smaller

 

[Celt83]

What size net are you using? We had a 354 and she hated anything more than 3600.

Have you tried pulling the tention leaver in front and holding the net in place off? Sometimes we have to leave this off especially if it's a new net for a 100 odd bales then it's fine to put back on. You will still have enough tention on the net.

Our fusion acts the same.

I had a 46, so plenty of net experience with the Claas system.
Clean under the net, and get rid of any surface rust. Dont have the net brake arm too tight on a new roll.
Check the drive belt that drives the clutch and roller, good order and tension.
Check the rubber roller and the metal one that's squeezed to it are free to turn, no rough bearings. Make sure that the two rollers are gripping together property, the springs can lose their strength.
Stick it in manual netting, power up and press the button with everything stopped and you should hear a good click/clunk which means the clutch is working.
Then do same with baler running hold the button down, and the rubber roller should keep turning, even on an empty baler.
I found that sometimes the rubber roller became too dry and hard after working in dry grass pollen or dusty straw. A right good steam clean worked wonders on ours. Sometimes it had to be a lemonade bottle of water from a cattle trough and a scrubbing brush. The roller gripped then.
If all that is right they are generally a good working net system.

I will post pics tomorrow

I’ve never threaded a class like it has in the picture. Always do one bar less.
