3-Point Hitch m7040 kubota

[Dave M7040]

Did this, but now rereading, I did not take a measurement in the down position. I had a landscape rake on the 3pt and did not want to take it off.

When I first got this tractor, it was noticeable that I did not have the lift height that I wanted. I adjusted the side lifts to the farthest hole on the arms, and also put the hyd top link in the lowest hole on the tractor. I'm fairly satisfied with that, but still not like my other M7040 that had R1s. Assuming the difference is the tires.

My center pin height is 27".

I checked the highest point to the center of the lift pin and got 28 3/8"
I am in hole B on the lift arms.

I have a blower on so could not measure the lowest.
I have Trygg studded chains on so these will raise the tractor up perhaps one inch.
My lift cylinders on the 3 pt are different than the ones in the page from the WSM I posted earlier.
The cylinder push rod is not exposed on my tractor.

See the crude drawing below. (I think we are talking about the same thing.)
Of course, theory is fine but to find out for sure requires an experiment!

Dang I've forgotten most of the Algebra & trigonometry I took in high school so I'm lost on your drawings but I still think with pin in hole in draft arm closer to tractor will raise implement higher!!!!!!!!!

You have R4s? If you went to hole A your lift would be higher, and you already have 1 3/8 on me.

My main use of the tractor is to pull an inverted snow blower with a rear blade made from very heavy steel plate.
When the blower is covered in snow and ice I was having a hard time lifting it when using hole B hence my use of hole A.
This fall I had set my hydraulic pressures so I may be able to go to to B and gain some height.
If you are missing out 1-3/8"( and likely more since you are using hole B) then I would do the procedure first suggested by GWdixon.
The post I made (including a section of the WSM) seems to say that the simple test is to raise the arms as far as they will go and then try to lift them further by hand.
If they will go up more than the small amount listed by Kubota then you adjust the rod since you have some unused travel in the hydraulic cylinders.

OK, re-reading this thread brought on some other random thoughts.

To review: The OP says that he cannot hook up his disc even when the 3PH lower link is raised to its highest point (the attachment balls are too low). Thus, even if the disc could be hooked up, there would be no remaining lift to get it off of the ground.

The OP states that he has two adjustable lifting rods and that they are adjusted as short as possible.

That said:

> Try adding air to the rears until they reach the maximum allowed for the tires. The air pressure in the fronts could also be lowered. Since the main use is to load bales with the FEL the fronts may be pumped up.

> A couple of concrete building blocks could be put down in front of the disc and the tractor backed up with the tires ending up on the blocks. The telescoping balls should allow for minor alignment issues. Now that the disc is hooked up you may be SOL though because as soon as you drive off the blocks the disc will engage the soil and not be able to be lifted for transport! If it is where discing is to be done it is not so much of a problem.

> The photo in post #21 illustrates a point I was trying to make earlier. If attachment point A is used then the attachment balls will be lifted a bit. The lower link will be further from the ground. A higher lift might be had with attachment point B but not much. Remember, the OP needs for the end balls to begin as high as possible.

> Finally, if this issue is with all attachments then the OP could rebuild the attachments with the lift pins placed in the optimum position to get the desired results for his tractor. A cutting torch, a welder, and some steel plate matching the original would be necessary.

Have a M7040SU here, I know a little different, but same 3pt diagram in my manual.

I have three sets of holes on the end of the lift link "2" in the diagram (where the pin that "B" points to is), would easily raise the lift links a LOT. Does the 7040 not have that?

Sorry for delay on giving a update. And thanks to everyone for advice on what to try. Well I tried everything that everyone has said to try and then I finally took the tractor to the Kubota dealer. I only got 1 1/2 inch more lift after making all adjustments still not high enough. Then when I took tractor to Kubota dealer, he told me I had to put ag. tires on take the r4's off. I can't believe when you have r4 tires on your tractor you can no longer use 3pt. implements, that is pretty much what the Kubota guy told me. How does a company stay in business when they sell a product that does not work ? I well go back to Ford tractor and "NEVER" purchase another Kubota. I now have a tractor that is useless !!!!!! Thanks again for everyone's help!!

before you take a hit in changing tractors, you might call Kubota central and explain your dilemma with dealer, etc. maybe they could cut you a deal on the right tires. you're right, that lack of info is deceptive on the dealer sales dept. otherwise, the 7040 is a great tractor w/o all the new tier 4 stuff. best regards

I got R4 tires and I don't have that issue. Use 3pt all the time.
