Lely Welger 235 Problem

[Shane s]

Will anybody be able to point me in the right direction to sort out a problem on my baler.

It is a 2010 Lely 235 profi

All in all its a great baler however i have found near the end of the year the netter is messing about when im baling wet grass.

She is bunching up the net under the feed roller and the net isnt going into the chamber. The baler is also not spreading the net the full width of the bale some times in wet grass only.

I have the bent foam roller and i have adjusted the break etc however it never seemed to make much if any difference. Any help is greatly appreciated

Are you sure there isn't bits of net gathered under the feed roller.Had this trouble on my 245 when it was new,occasionaly wouldn't take the net in.Had to clean it right out underneath or it would happen again,turned out to be a batch of rubber rollers from a new supplier,that was cured when the hay dust started to get on it.Net wrap doesn't like really wet grass tho,nothing to stick it to the grass.

Yeah i have to keep cleaning them out completely and it is a complete torture as there isn't much room to get you hand down the back to pull it out.

Any little splits or chunks missing on the rubber roller are likely to make it hold onto the net,other makes of baler recommend talcum powder on the roller,but shouldn't be needed on a welger.

 

[Shane s]

no splits on the roller, the net has went around the rubber roller on me about 5 times the year but i am always very careful when taking net off and do not alow the knife to hit the rubber roller

 

[Sharpy]

Not familiar with those balers, but failure to spread net is usually insufficient tension on the net. (Usually better tension at the start of the season as the contact surfaces are not really shiny) This can also cause raggy cutting of the net and hence poor feeding in of the net which causes the raggy end to wrap the rubber roller as it catches on a surface and piles up.

 

[Landrover]

Clean out behind the rubber roller, probably full of dust and rubbish, turn/replace the net knife so it's cutting cleanly, bales a good shape or are the swaths uneven ?

As said above clean out under the rollers, turn the knife round and pressure wash the rollers.

sounds like you need a new net knife. We had this problem changed it and it was fine

Normally it will just not cut the net when it needs turning or replacing.If its only when the grass is really wet it could be water flicking onto the rubbber roller.

If its not cutting clean and leaving a ragged tail, it will pull the net in from one side for a start, causing it to not be fully spread out by the time the knife drops again. Admittedly not quite so noticeable on a 235, but worse on a belted due to the distance the net goes before it reaches the bale..
But as above, sounds like clean out the hole behind the net rollers, make sure steel roller isn't rusty, turn/replace knife, plenty tension on the brake, and the 2 springs holding the rollers together should be adjusted so you can get a 20p between the coils and if the little chains for the brake bar springs are still there hook the springs direct on to the hooks.

ill have a look and do this. I will need to replace my knife, howevrr i was already planning on doing so as i had to turn around n summer as it became completly useless and would cut. I will check the tension of the 2 rollers and give it a good power wash.

Does anyone on here know if its a big job to take the reel of a 235? i want to change all bearings and changed all tines to mchale ones. The reason i want it of is because it will make it much easier to work at it and there is some bolts that have rung off where you bolt the bands on so i need to drill and tap these and its very awkward to do so when on the baler.

Its not the worst job, rams off, chains off, clamp that holds pickup on round the auger pivot. then use a loader to push the baler back up and over the pickup.
I think that's about it.. its been a while since ive had one off.

If its not cutting the net clean,it will pull it in as soon as the next bale gets big enough to push against the top rollers,so if you've just turned the knife it wont be that,should do 10000 before turning again but follow the rest of this advice,i bet it will work fine in the summer...

Just be aware putting stronger tines on you will put more pressure on the cam bearings and track as well as the tine bars.I did it myself,ok for a couple years but fell to pieces after that.

Yeah that only thing i am afraid of but im sick of changing tines. im gonna replace all bearing and check the cam tracks, is it possible to turn cam tracks or somethiong or is that only a rumor i have heard?

No you will need a new one eventually,i had to change all the tine bars on mine as I had a couple break.But I do have some very uneven marshland to bale each year.The new camless pickup is a dream to use now,one bearing each end and that's it,the rest of the pickup reel is much stronger too.

Can anyone tell me do I need to remove all the net holding unit to turn my 325 baler net knife around, the knife is looking a little rusty can I just sand paper it down to clean in or do I need to flip knife around. The baler is cutting tamma hedge to edge fine but is failing on every 6-10 bales of using the MVF net wrap.

 

[balerman]

If it’s the performance HD net from mole valley,that is very tough to cut.Don’t go sanding the knife,all you need is an m10 spanner to slacken the studs holding the actual blade on its holder,pull the blade out and turn it round.It can be turned 3 times cos there is 4 cutting edges on it,but cheap enough to replace if it is very rusty.
