Reardan Wa. | We have a MF 2190 4x4 Baler.
Cannot make a tight bale.
We are running 380 Load, (Maximum). And at 15% moisture we are only getting a 1550 lb. bale in alfalfa.
We use to make 1800 lb. bales with our old Hesston 4x4.
The hydrulic pressure is about 1300 lbs with 380 load, can't seem to get over that.
In manual we can get the presure to 2800 lbs.
The dealer is puzzled, can't seem to figure it out.
Any thoughts or suggestions?

SEON | I'm a LBX guy with a old Hesston or two kicking around but......how much hay are you putting in a flake? I had this happen to me once and it turns out the dealer mechanic adjusted the tension on the adjustment spring by moving the lever a couple of notches. This means the stuffer trips more often meaning less product in the pre compression chamber. After the flake is in the chamber,the plunger can only do so much.
Took me a while to figure that one out.

Alberta, Canada | If you are not in a terrible hurry, decrease your ground speed if you can. The more strokes per flake, the more the baler packs the crap out of that bale. These new balers have increased capacity, but you can't utilize that capacity and still make heavy bales.
Edit: this will also increase your flakes per bale, more flakes per bale the higher the weight usually.

Huntley Montana | How many flakes per bale? IF your STUFFING fast the 380 load will be met buy compressing the wad. IF you are getting 380 LOAD you might have to slow down to get higher pressure on the tension cly's.
More flakes will increase the weight. |

Texas Panhandle | That is an odd problem. You shouldn't have a bad load cell if your pressure is running that high. Like others have said try tightening your flake adjustment. Also I'm wondering about the alfalfa. Are you baling with humidity moisture or stem moisture? If we get in a hurry and bale a little green we have to bale with less humidity or we get high probes. That in turn results with losing some leaves and henceforth weight. Cure it out good if you can and bale with good humidity. Still I haven't had bales weigh less than 1600 lbs. and I run 280 to 300 load. |

Pasco WA. | Hopefully hank will see this post because he had the same problem with his 2170.
Even with bone dry alfalfa your bale weight should be heavier and you should have more pressure.
How many flakes per bale are you getting? I usually run around 32 on my 4910's. |

Reardan Wa. | We're running 30 flakes/bale.
When the service guy was out, we tried slowing down to 40 flakes / bale, the problem got worse.
Also tried tightening the stuffer spring to get a heavier flake, didn't seem to help.
Also dried upgrading the software on the moniter from 2.3 to 2.7 (latest).
No difference.
I have a neighbor with the same baler, in the same hay he runs his load at 320 and gets a 1800lb bale.
I'm at 380 max load and can only make a 1550lb bale
Thanks for your replies. David |

Pasco WA. | How much pressure is your neighbors baler running?
Have you tried running wedges? |
|

Reardan Wa. | He's running around 1800 to 2100 lbs presure.
And no I haven't tried wedges. |

| Are you running any restrictors in the baler? If you are, remove them. If not, eject the bale and make sure your bale chamber is clean. Higher hydraulic pressure does not necessarily make a heavier bale as that is largely determined by plunger load, but a low hydraulic pressure may indicate that there is something inside the chamber leading to excessive resistance on the bale. Alternatively there could be excessive resistance on the plunger, producing an abnormally high plunger loads. Material build up in the plunger rails can do this. That being said, 1500 psi for 15% moisture is just about right for a 3x4, I'm not sure about a 4x4.

Bonanza, Or | This problem is very familiar to me. I was having the very same problem with my 2170, I could run 285 load which is max load and only get the pressure to come up to 1500 lb and I would struggle to make a 1330 lb 3x4 bale in 14% moisture alfalfa. We had welded in wedges several years ago to help bale shape and we did not think that was our problem so we checked everything and I mean everything. We replaced the pressure relief, checked the increase-decrease cartridges, checked cylinders for bleed off, you name it we checked it. Like yours I could built big pressure on manual.
We ended up cutting the wedges out that had been put in several years ago and we put one set on the door just in back of the hinge point. This solved the problem and I now build pressure and get bale weight and nice bale shape.
We think my problem was that the front wedge was causing a false high load reading which would in turn make the pressure back off.
One other thing I would check is the stuffer timing. If it is off it will do strange things with the load.
I think that each one of the balers is a bit different. I also wondered if they have ever had to reload the software for the brain of the baler.

Reardan Wa. | We're going to try switching the black brain box on the baler to see if it makes a difference. |
|
| |
|
Bonanza, Or | Post back if it helps. Mine still runs more load than any other around here to make the same bale weights. |
|
| |
|
Reardan Wa. | I also tried disconnecting the connection on one side of the plunger arm load sensor and found that one side runs about 300 lbs lower hyrulic pressure than the other side.
You can bale with only one load cell, you just don't have driving arrows.
Pesonally, I think there's something wrong with the load sensors or the calibration of them. |
|
| |
|
| If the pressure dropped with one unplugged, then it is likely that the one still plugged in is the cause of the problem. However, a bad load arm will usually cause the drive arrows to favor one side as well and cause you to drive the baler into making curved bales. |

|
Bonanza, Or | You can go into the monitor while baling and watch the HZ readings on both arms to tell if one is bad. On mine they both read very close so we ruled them out of my problem. |

Townsend, Montana | I know this is a very old post, but I did check to see that the OP logged on less than a month ago so I am going to resurrect it anyway.
To the OP, did you ever get this problem fixed? We have 4 2190's and one of them won't build as much pressure as the other 3 even with the load maxed out. Unplugging one crank arm lets it build a little more pressure.
Did you find a solution?
