Claas 255 net problem

[Claas 255]

Hi all..
I have an issue with a claas 255 roto cut. The automatic net wrap is not engaging when the bale chamber is full. Ive changed the switch on the door but still no joy. Now it wont engage the net manually. The control box looks as it should be with all lights working etc. Any ideas on my problem? Anything else i should be looking at? I have my fingers crossed its not the magnetic clutch... any help would be greatly appreciated.

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

Worth a read, my old 46rc would not feed net in this year, it turned out the metal feed roller bearings were kaput, Angus. Edited to say, Machinery section 14th July @Red Fred created a similar thread, I thought I had linked it, Angus

Must check it out. Forgot to say also that the beeper is not going off either to let me know bale is made.

the beeper is set off by the tail gate sensor

if you have the tractor stopped and the control box on and press the tail gate switch manually you should be able to hear the net drive clutch click in then out again after a few seconds if its working

From the memory of ours that is correct, but the bale ramp switch had to beep to finish the cycle or it wouldn't reset for auto netting the next bale.

Had a problem with a 360 not wrapping in either manual or auto a few weeks ago. The clutch wasn’t clicking when pressing the manual button. I ended up taking the netwrap storage box off to get better access to the clutch. The earth wire wasn’t great so remade that, but that wasn’t the problem. Put 12v off the battery direct to the clutch and it would click. Check the wiring around the clutch and clean it all up first.

I baled 200 bales by running a wire from the clutch to a switched 12v supply in the cab, activating the switch for about 3secs to start the wrapping cycle. Claas mechanic looked at it a few days later and said it was a faulty UBM module (small box behind netwrap storage box), new £750, repaired by David King Electronics for £250

The bale cycle only restarts when the door is open and the kick ramp goes down (hold the door switch down and stand on the ramp at the same time)

clean out round the bale ramp switch and tail gate switch and make sure they are both free and going in and out ok for a start

Hello yea done that an plugged monitor in with tractor off it bleeps when press door open switch an when put foot on the ramp it bleeps also can hear clutch kicking in an then turns off couple seconds later..

 

[Henarar]

is the bale ramp coming back up in place ok after you let the bale out ?

 

[Howard6180]

Yea it’s coming back up no problem after the bale is let out good pressure there on spring

I’ve read about a v belt brake? What is this or how does it work?

Its a brake on the net roller drive belt, a 255 should have one

 

[Howard6180]

Ok I see how can I check to see if it’s working or not?

Its sprung and worked by an over centre leaver, its ether on or off, on is for net off is for string

 

[Howard6180]

Right ok I know what you mean now. It’s in the on position. Had a look at it.. a bit baffling this problem I’m new to the whole round baler experience

 

[Henarar]

It sounds like its just not completing the cycle for some reason.
If when the light is flashing you switch the power off and back on is it ok then ?

 

[Howard6180]

Yea it’s ok when reset the monitor an turn on the light stays solid. So far everything good as far as I’ve tested

 

[Henarar]

the last bit of the cycle is closing the tailgate, so tailgate switch not set right or not working or wiring

will it run a cycle by hand OK ?
