Hesston knotter problem.

[Chae1]

One knotter on my MF190 square baler is slow to release the knot from billhook every bale. Every 4th or 5th bale it doesn't release it at all.

I've checked stripper arm clearance and it's fine. Twine tension top and bottom seems fine. I've also let tension off of cam that sits against billhook. So it's not too tight and causing it to hold onto knot. Twine discs look set same as rest.

I'm stumped to be honest. Would be grateful of any advice, ideas.

Had the same problem here , just a slight decrease in billhook pressure sorted it , knife needs to be a razor .

+ 1 for knife, if slightly dull it pulls the knot out of the twine disc slightly too much during the tying cycle,you can lengthen or shorten the tails on the knot by slackening or tightening the twine disc one flat of the nut at once but sharpness of the knife is critical,even if it looks sharp it won't be!
the other thing is the stripper arm going far enough past the end of the bill ,is the roller on the end worn with flat spots on it? stripper arm can be bent to make it pull knot further of knotter bill or id knotter bill worn,if yo have a spare change it. hope this helps.

Having this issue on a brand new massey. Tried all sorts with the stripper arm. Massey supposed to be sending someone out as have had all kinds of knotter trouble with it.

Is twine arm rubbing bill hook tight enough to pull knot off normally have to give ours a good bash and have them rubbing very tight to work properly

Change the knife. Change the billhook, give the stripper arm a good wallop downwards so it rubs the billhook

The stripper arm was new last year on this knotter. Would have been new knife on stripper arm? So was billhook. It did about 1600 bales this year before it started causing problems.

Is the beak on the bill hook bent or a racked bit on it

16 bales is enough to break something let alone 1600. Only takes 5 mins to change, if it doesn’t work you know they’re good to keep as spares.

There is a bit on end of it. Well spotted. The stripper arm does seem to be in contact with it for full stroke though.

How well do you get on with your 190 doing 40ft swaths or old girl was fine with 30 now weve got 40ft on axial flows dosnt like feeding up front so well could do with pressure rollers to force crop down if it could be done

If I can get the tractor over it. It will generally bale it. I'm 99% barley straw though. Biggest header I've baled behind this year is 35ft. Was in a huge crop of spring barley straw yesterday and was just crawling. Was around 28 flakes per bale.

 

[lexion780tt]

Ours will bale any wheat straw but put a thick crop of muggy spring barley straw up to and it the knotter always mess about and pick up carnt handle it

Been alot of annual meadow grass in bottom of spring barley crops up here this year. Like baling haylage some days.

That’s my experience too. Long long ago!

We have a MF 185 baler it dosn't like big rows of crop but have had 2 MF 185 11's baling and they have baled the straw easily they have 2 bigger bigger augers in after the pick up reel to move the crop into the forks.

Tighten the lower tensioner right up, and file/sand the bill hook smooth.

 

[Chae1]

I cut the strings and put some electric scales on top strings. The problem knotter needed 100kg of pressure to get it to start moving. Others were 70kg.

Will get underneath it tomorrow and measure tension on bottom strings.

As been mentioned above but also worth noting that everything looks rather dry? how free is everything? Is oil getting where it should?
