750a Guttler spring problem

[AF Salers]

Having a problem with the Guttler pressure adjustment spring not staying in its setting on some of the coulters.

The spring isn't tight enough against the Guttler arm and thus in the setting pegs and when the coulters are lowered into work the spring is popping out of the pegs and into the 'no pressure' position on some of the coulters, and others where it isn't popping out it is wearing the tip of the peg to a point. You can hold the spring tight against the guttler arm, but when you release it it goes back to its original place and rests on the very tip of the peg.

This is a new 3m drill this year and has only done approx 400 ac

Has any body else had this problem? any cures?

That's a new one to me, I've known the spring to occasionally slip off but it only happens rarely and only on the lowest Spring pressure. What is also strange is that when we had the operators course at @Feldspar 's the other day his were so strong that they were hard to change position. I know they get easier to change after a bit but it strikes me that your drills are at opposite ends of the spectrum. If you are concerned and getting undue wear you need to be talking to your dealer.

I can agree with that Simon, the springs I my new drill last year were really strong to change, this year they are a lot more moveable, probably due to all the times I have changed them to different positions trying to improve the job.

 

[Tractor Boy]

My drill has only done about 400 acres and the springs are so strong they are hard to move between the toggle settings.

 

[AF Salers]

Thanks to those who have replied, yes my springs are still very strong, the problem is that they aren't riding tight against the guttler arm but instead on the tip of the peg (see pic above), so when they bounce a bit they are slipping off the peg and releasing the pressure on the guttler. Have spoken to the dealer and he is coming to have a look.

Many thanks

I don't know if it's the angle but the arm coming off from the coil looks bent in comparison to the coil. Can your dealer get a new spring for comparison?

The 4m demonstarator machine that RBM have let me have, until my own arrives, has exactly the same problem. 5 or 6 of the springs ride on the end of the pegs, particularly on max pressure, and one of them will not stay on the top peg. I have resorted to clamping it to the arm with a U bolt to hold it in place. The drill has only done 150 ha.
RBM came to it today to have a look. they have very little experience of the drill. They took some pics and will report back.
It seems to me that some of the springs are not made correctly. The arm that sits on the pegs has too much of a curve on it.
I have been keen to alert RBM because I am concerned that my new drill will have the same problem. It would be better to sort out the springs before they wear the tip off the pegs which would be more difficult to fix.

Same issue here, 35 springs almost too tight to move (even after 1100ha), & one that keeps coming off. Cable tied it for now, but have raised it with dealer

Update:
2 springs now slipping off the pegs.
Tomorrow mornings first job is to make some spare clamps to carry with me in case others start doing it.
JD need to get their arses into gear over this.

 

[AF Salers]

JD are supplying me a couple of new springs to see if this rectifys the problem. Have made up some clamps to prevent the affected springs moving from required setting in the meantime

 

[AF Salers]

7 springs now clamped on position

Anyone get anywhere with JD over spring issue? Had 2 looking like this yesterday (note I should have taken picture before putting spring in highest setting it was in the no pressure position when discovered) I am wondering if I have got too much tension for gutters with weights and ware to the peg is occurring as a result. Spring now wouldn't remain in either middle 2 positions so either full or no load.

I've got mine on the highest tension with guttlers and weights. So far no problem like this. I do,however, have the tabs breaking off the seed tube issues. JD have just sent me new seed tubes which are exactly the same which seems pretty pointless!

JD say that they have changed the manufacturing process, so they would look the same. Whether it's enough is another matter. I imagine that they quench the tubes in oil after welding on the tabs to make them less brittle, but that's only a guess.

@Northdowns Martin jd sent the dealer a set of bevelled washers to swap for the flat washers on the bolt that the gutter wheel arm pivots on to try to reduce any movement. This didn't seem to make much difference at all, so the fitter after some discussion was told to manually bend the springs a bit so that flexed back onto the peg more. This seems to have helped a bit, though for how long I don't know as I have only drilled about 20 acres since.

 

[H.Jackson]

I have two springs do this, with the coulter up lift the springs arm up above the arm and pull towards it this bends it just enough to stay on the pin.

 

[Northdowns Martin]

Any updates on this subject? I have tried to get some help from my drill supplier, now not a JD dealer without much interest, so was wondering if any drills still in warranty had received any mods?

 

[Big-Al]

JD are so slow at doing anything, i have several problems with my 6m, but not noticed the springs moving off the pin, we are approaching a year since it arrived, i'm sure they will sort it in the end, just takes so long to filter down the from the monkey to the organ grinder, i was also surprised that the 750A was stuck out on the side lines at the JD stand at LAMMA do they not want to push the drill?

You've got to remember that drill sales hit bit tractor sales, and that they sell themselves. At the moment the factory assembling them are close to capacity. Coupled with drill courses ( I haven't forgotten you ) that gives them free advertising they probably don't have too try too hard.

Anyway you must have finished your morning coffee by now, haven't you got hedge cutting to be getting on with?

I have just woken up to early and come out of the hibernation cave might go back to bed as nothing on today as the drill is on calibrated ready to go ish April
