M7060 loader question

[houser52]

I've had my M7060 for a couple months and it only has 30 hours on it. The other day while using the FEL and bucket I noticed that the loader would not lift the tractor's front end off the ground. Example- With the bucket sitting flat on the ground and pushing the joystick to the right, the bucket will not dump. My smaller and older L3600 will raise the front end easily when in the dump mode. I've used it for 25 years without never had this issue with it.

The dealer picked it up a couple days ago to repair a hydraulic leak and I told them to check what I just described. Well, the dealer calls this morning and says that the leak has been repaired. He also checked the loader's dump function and everything was fine. He also said not being able to lift the front end was the way those tractors are made and that he compared other new ones on the lot, they also wouldn't lift the front end. The reason being that the dump cylinders are small and didn't have the capacity to do it.

I for one am a little skeptical of their diagnosis. Is it normal? Something I can personally look for?

I'd like to hear what you guys think.

Do you have trans in neutral & no brakes applied when attempting to raise frt wheels with FEL?

What it sounds like he is saying is that it doesn't have enough lift capacity to lift that much weight. It might be the case since that tractor weighs a little over 5,000 lbs. and the weight lift capacity is only around 2,900 lbs.

But I would think that it should be able to since my tractor weighs a little over 2,200 lbs and my FEL lifts only 1,100 lbs and my bucket will lift the front wheels off the ground just like your L3600 does.

It won't raise it when sitting on level ground, no brakes and in neutral.

Where is the fast dump mode on that tractor? Most tractors have the fast dump mode all the way hard right. I know that some of the Kubotas have fast dump mode just to the right and std dump all the way hard right. Standard Ls and Mx series only have fast dump mode.

The loader typically will not lift the tractor as you describe when using fast dump mode.

Please report back as to the location of fast dump mode on your M7060. :thumbsup:

My thought as well. My L4060 wont lift the front dumping the bucket. It will just fine if I dump the bucket then lower the boom.

Technically I think I have a 4 stage valve on the bucket circuit. Going all the way over should go from a regen dump to a power dump. Which should lift the front end. But have never been motivated enough to remember to try. The economy Kubotas like my former L3200 only have a 3 stage valve with regen dump, no power dump.

This is exactly as I was thinking, you have a 4 position valve as do the M models. I just am not sure which is first, the regen dump (fast dump) or the power dump on the M models. My thinking is that he is going into regen-fast dump position and it will not lift the tractor in that position.

On my Mahindra loaders, the power dump is before the regen-fast dump which is hard right.

MY MX is a little smaller than 7060, but it Effortlessly lifts the front of the tractor w/ the bucket curl cylinders at engine idle. My loader weighs about 1200 lbs and has a rated lift capacity of 2450 lbs.at the pins. I do NOT have a Kubota bucket. I use the 66 inch QA bucket from my IH model 2200 loader on my IH 484 utility tractor. I have an aftermarket Agrital cab on my MX, which weighs 900 lbs. doubt that makes a difference.

I believe ALL tractor loader control valves are proportional style. The meaning of which is simple, the further the lever is pushed, forward or rearward and left to right, the faster the hydraulic circuit will respond. Honestly, I have never heard of a quick dump position? Move the lever to any extreme simply allows the full flow of oil through the circuit. The obvious exception is the float position, if so equipped.

Unrelated, my little ford and IH 484 also easily lift the tractor right of the ground using the curl circuit.

Mine has the fast dump all the way to the right. It will dump either fast or slow just fine but will not raise the tractor up either way.

On the kubotas, at least that I've seen that have a 4 stage valve, the first "notch" (no real notch, like float) is regen dump. The all the way over is power dump. It makes the most sense to me as regen dump makes sure it dumps fast & doesnt stuck in air (leading to a floppy bucket). That is where it will help the most with the least training.
