Three Point Control Range

RAllen · May 7, 2001

Please let me repeat. Fresh from the dealership, I had more range. There was a difference between 1 and 4. My 3-point does not budge until I get well over 5-6. I have not checked the adjustment so I might get to Bird's 4 position but why have a 1-8 range- I paid enough to expect that much control.

Same issue, also in 'spec' on my 2000 2710. Agree with Bird, I'd like the extra ability to make fine tune adjustments. Actually partially responsible for getting me stuck in the muck on Friday (mostly my fault, but didn't help), was almost through a wet area and tried to feather my mower deck (same control) down a bit and it went to far...... Will keep watching this one for a fix.

I checked my 2910 today. It's adjusted correctly to be at full height in position 8. Full down is around 3.

The more I think about it, as long as you get the full up/down lift range, who cares if the numbers are off on the control label. If your lift is fully up at position 8, then you have full range.

Bird · May 7, 2001

hayden, my 3-point has the full range of movement, so it's not a serious problem, but it doesn't make sense to me for the lever to be numbered 1 to 8 if the first 4 do nothing. And it would be nice if you could move the lever farther at a time to make minor adjustments.

I am glad your 2910 gives a range of at least 5. Seems Bird gets a range of 4. My range has slowly reduced from an estimated 6 or 7 to a range of 3 position points. You might feel differently if you had a smaller range.

I think it depends on what you are doing with your 3 point. I do alot of work with a boxblade and rock rake where fine control is important and I have problems. Additionally, I am having problems with my Delta Hitch. I do not think I am getting a full range of movement as well as the control sensitivity mentioned. I believe this may be a progressive problem and will continue to get worse. It does seem quite a few folks have the same problem.

Kubota makes great tractors. If the range is really 3-4 as opposed 8 then the control should be marked as such. Anything else is misleading period

For all it's worth... my new L2600 has the same problem. Full lift at 8, but doesn't begin to raise the lift arms until 4 or 5. It's on my list of questions to ask my dealer. I understand that the bottom of the scale is float on my tractor, but exactly what is the bottom of the scale...? /w3tcompact/icons/crazy.gif

I have adjusted the flow control to try and stabilize the lift, but can't seem to get beyond a very jerky movement when making small adjustments.

FarmerBob, you said "I have adjusted the flow control to try and stabilize the lift, but can't seem to get beyond a very jerky movement when making small adjustments."

If you are referring to jerky movements when making small upward adjustments, Those "jerks" worried me when I first bought my L2250. I came to the conclusion that the position control is so precise and the lift response is so rapid when the control senses that you want to raise the implement and responds causing the implement to raise upward so quickly that the tractor feels like it is the tip end of a whip. This condition gets worse with heavier equipment. I've often thought an accumulator plumbed into the system between the control valve and the lift cylinder would dampen the shock of the pressure hitting the cylinder and result in less shock load on the entire machine. I don't know enough about the system to design one, but maybe someone could comment on the feasibility and benefits of one.

I understand the flow control only adjusts the downward movement of the control arms. It is adjusted for implements of varying weights to provide a controlled desent but does nothing for the raising speed.

I understand not having "full" range with a box blade. For example, a plow would run lower than box blade. I also have noticed that I cannot do any minor up adjustments either. Move the lever up it two or three positions, nothing and then it jumps up. I always have to go up and then fine tune on the down stroke. Asked the dealer, said that’s how it works... OK. But what I don’t understand (and doesn't take alot) is how your range is “reduced”. Is it that you can no longer say stop at 6 ? Or is it not coming all the way up ?

hayden · May 8, 2001

Have you had a chance to check the adjustment to see if you are reaching full lift height? If it's out of adjustment you might recover some of the range by correcting it. Regardless, from what others have reported it's unlikely you will get a full 8 positions of movement.

hayden · May 8, 2001

Yup, it's sounding like sloppy engineering to not have the control range better match the label.

DaveM · May 10, 2001

Bird- Sorry to be a little slow with this data point. I took some notes last night and got very similar results to your tractor's figures. This is from a 6 week old B2710 with 22.3 hrs.

With the position control all the way down, lower links very low to the ground, when I move the control up the links don't move until the leading edge of the control lever reaches "4". Then raises all the way to the top of the range, "8". Moving the lever down from top position, I see movement when the leading edge of the lever reaches aprx. "7.5" and continue to see movement until the lever gets to "2". Then nothing to the lowest position.

I'm not sure what this all means. Still a tractor newbie /w3tcompact/icons/smile.gif but it does seem odd that the operation is not symetrical going up vs. coming down AND that there is some "wasted" lever range.

RAllen · May 10, 2001

My control lever does nothing until I move it past 5. I THINK I have full upwards range at 8. Between 1-5 I have no movement from the lowest position. If I am at the 8 position, I get downwards movement all the way to 4-5. At that point, most of my implements are on the ground. I tried it with no implements and it appears to be about the same.

It appears that what we have is "normal" and the 3-point works just fine. It just doesn't seem right to have all that range that doesn't do anything.

I agree!

I agree!

Me too!

Somebody call Mr. Bota and straighten him out. /w3tcompact/icons/mad.gif

After reading all of these posts I went home last night and checked the travel on my JD4300. There are not any numbers on the adjustment scale on my tractor but I do have upward movement over the full range of lever travel. Just lucky I guess./w3tcompact/icons/smile.gif

How did you come to the conclusion its "normal" other than being such a wide spread problem?
Waiting for parts before I go to the dealer. I am going to STRESS the dishonesty of having such 1-8 range and a real range of 5-8. I really seem to remember the tractor had a much better range when it was delivered.

Rick

DaveM · May 11, 2001

Rick- Your range is certainly smaller than mine or Bird's but I still look forward to hearing about anything you learn. Hopefully it'll be good news that everyone with a 2710/2910 can benefit from. Do 2410 owners have the same condition? Next time I see my dealer I'll be sure to inquire about this as well. In fact I should see him next week when I get a new tiller and maybe a new box blade if it comes in too. As you stated, having fine control when using a box blade is a real asset. Or at least it sounds to me like it would be /w3tcompact/icons/smile.gif.

Good Luck!

Dave

Rick, I guess the widespread "problem" and my being too lazy to actively pursue the matter much farther is the only reason for that conclusion./w3tcompact/icons/laugh.gif/w3tcompact/icons/laugh.gif But if anyone comes up with a way to make it better, I'll sure be glad to hear it.

I have a 2003 L2600DT. I have the same problem except mine only reacts in the last inch of travel. I had posted looking for assistance, but none so far. I have read of others with the same problem. Inconvenient at worst. Implements still raise and lower. At least it isn't the shudder problem.
Haven't tried with no load and haven't talked to Kubota dealer about this.
