B3030 Position Control for 3ph

[Machold]

Just got my machine back from dealer for a service call. I also told them my 3ph did not move up until the no.4 position. OK, they would adjust it. Now it goes up when it gets to no.3. Some adjustment! How can I get it to work properly from 1 to 8?

Mac, I would call the dealer back and complain. See what they say. Maybe they will send a technician out to your place and do it right this time. Good luck! Stanley

That's how mine is as well. I'd be interested to know what they adjust to get it to start lifting at a lower number. To be honest, I never really paid it much attention. I just figured that the numbers on the scale weren't accurate. Maybe they should have numbered it 1 to 5.

The numbers don't really mean anything. They are just for reference.

Mine as well. I don't care because I have full movement of the 3 point.

You can try adjusting the position control feedback rod to get a little more range of 3PH movement but that is probably what the service tech has already done for you.

Getting any use out of numbers 1 and 2 on the scale are probably unrealistic. On mine, 4 was low and 8 was high. Actually, 9 would have been the high had the scale gone up to 9. After adjustment I go between numbers 3 and 8. As mentioned, it is just a reference number.

I also slid the little thumb-screw stopper up from 0 to 2 just so I don't waste time trying to raise/lower the hitch within the 0-to-2 "no-zone".

Thanks for the replies. Seems 3 - 8 is normal range. Thumbscrew stopper, neat idea.

I've got a similar question about the 3pt height on my L3540. My box blade does not leave the ground until the lever is around #7 and when I get to the end of travel for the lever at #8, the box blade is not very high and scrapes the ground over minor bumps and dips.

I plan to take some measurements this weekend when I can get it into the garage and on level concrete. What should I expect to see for max height of the lift arms? Or is there an expected range of travel between the lowest and highest points?

You can increase the lift height by shortening the top-link. You will need to get it on a relatively flat surface to determine how to adjust it for your use.

When adjusted properly, you should be able to lift your box blade pretty high.

I have a hydraulic top-link which really helps the function of the box blade.

Can you clarify? I'm not sure I understand how that would work. I thought shortening / lengthening the top link would only change the pitch of the box blade, not it's overall height. For example, I expect shortening the top link to make the back edge of the box blade higher, but not the front edge.

My expectation (perhaps wrong) is that I can have the top link adjusted so the box blade is level on the ground and still raise it to a decent height. It may not be level when raised, but that's OK.

OK - I measured from the ground to the 3pt pin at its highest point and it was 23". I then noticed a rod attached to the top of the left cylinder and it has an adjustment at the end. So I adjusted it to max height and now the 3pt is 27.5". This is much better and more of what I would expect. It seems like the cylinders are at their max extension, so I might back off the adjustment a touch.

Comments? Any down side to this adjustment? Is there a recommended setting for this rod?

The box blade will still lower to quite a bit below grade, so down travel was not affected.

Yes, I noticed the same thing. In fact, I suspect this is how the dealer raised the height of my 3ph, thinking that was my complaint. Now, it starts moving up at 3 and at 8 is very high. I will measure and report.

That will work. Also look at the ends of the lifting links or the lower hitch arms where the lifting links attach. One, or the other, and I can't remember has extra holes in it so you can change how high, or how low the lift arms will go. My B2620 won't drop my middlebuster deep enough in the soil to dig my potaoes without damaging them so I just switch the arms to the other mounting hole, and then the arms will nearly touch the ground, and the middlebuster goes plenty deep. If you look carefully at the photo you will see the other hole in my lower lift arm near the outside end of the turnbuckle.

By the way, leaving that clevis on when I take attachments off is a sure way to bend my check chains......... bent two before I figured that one out. I may be old, and sick, but you can't call me fast.

Thanks ChuckinNH - I don't know why I did not see those adjusting holes before... but last night I moved them up to the highest hole and now the 3pt pins go up to about 29" off the ground. :thumbsup:
