Info on Mahindra 6530 w/266 loader

[JIROBBI]

Hi,

I am digging around the stump. I am not attempting to lift stump with one dig but I do attempt to lift roots that run out from the stump. The loader has failed to lift several things.

My first encounter with lift was with my root grapple. It weighs 1,000 pounds. I noticed that it seemed to be weak lifting logs that are laying on the ground in various lengths. People lift 18 foot logs all the time with skid steer loaders and load them onto trucks 12 feet high. I watched as cleanup crews lifted large stumps and load them into trucks with sides 10 feet above the ground after Hurricane Katrina. I am attempting to do some clean up at this point on my own property.

I would like the tractor to start slower as I begin my dig around a stump. My kubota did start slower and I was able to get off the clutch much faster. I am assuming that the 12 speed would start slower.

I am not picking the back tires off the ground. I do have water in them. I should be able to lift them off the ground.

I do spin both front and rear tires when attempting to dig around the stump, especially when I hit a root. I do have the stump up, after tearing it up a little at a time. It was very hard on the tractor and on the clutch.

Both the 6520 and the 7520 are larger tractors. I got the 6530 because it was smaller in size and had a shorter turning radius. I just believe that the 7520 would have done more when it comes to the clean-up I want to do. For other work the 6530 will be fine. It is a little hard to get on and off.

I saw the results of what a 6500 can do to a grapple that was used in storm clean-up on the Missisippi Gulf Coast after Katrina. It was destroyed. My Root Grapple is better than the one I saw on the 6500 and maybe too heavy.

I hope that the dealer can help after the check he wants to do.

Thanks

I think you got the wrong type of equipment to do what you are trying to do...sounds like you need a backhoe, and save your tractor....if you are riding the clutch to get slower (for some reason), you are truely setting yourself up for a major repair...and probably one that isn't covered under any warranty, as the clutch is a "wear" item. Under normall usage, a clutch on a full sized utility tractor will last way beyound 20 years....sounds like you could need one in 6 months if you keep trying to "slip" it and use the tractor as a bulldozer. Just my 2 cents...BobG in VA

PS: As far as the loader, yes, I agree that something isn't right...have the dealer check the hyd pressure and specs on it....BobG

-Where are you running the throttle when using the bucket and attempting to lift logs or roots?

-Are you sure you have it in Low 1st Gear? The only unit I can think of that we carry that will go slower is the 7010 CAB and it has a Low Low.

-Are you sure the grapple weighs 1000#? that seems awefully heavy especially when you consider the loader itself probably weighs around 1900# (just a guess compared to the actual specs I have on a similar loader)

Hi,

The loader bucket is off and my grapple is attached by way of the skid steer attachment tool.

Skid Steer Extreme Root Grapple

This is the Grapple I have and it is the 84 inch. I believe that the 6530 is just barely enough to use this grapple. It does weigh 1,000 pounds.

I have their root bucket as well.

I get off the clutch at idle. It is not much faster than the Kubota 45 HP I had but it is a little. I thought that the 7520 being a 12 speed would have a slower speer in low/low.

I hope that I do not damage the clutch attempting to dig stumps up. I do not intend to dig very large stumps with this thing. I am sure that the skid steer is better able to dig than this tractor.

I also see that this grapple is a little big for the 6530. I will be using it in a bottom which was the hardest hit with down trees from Katrina. I can clearly see that the 7520 would have been better for this work.

Thanks

The 7520 has a High, Low, and Medium.......you would be able to go about half a mph slower on the 7520 which really isn't that much in my opinion.

I think you should get it to your dealer and get him to check that loader out just to make sure everything is in working order.

I agree, have him check the actual lift capacity with a scale, or at least put a pressure gauge on the loader to see if the bypass is set too light. Digging roots is tough, best done with a backhoe.

Hi Dave,

I am going to the dealer as soon as possible.

I bought the Stump Bucket to do some light work such as what is left from cutting 2 and 3 inch stuff that is too small for a stumpgrinder. I did tackle this larger stump. I finally got it but I do not believe that I will try many more.

I do believe that the breakout is too low. It does not even attempt to move with the grapple under trees that it should lift. I know that a skid steer has more power for that but this 6530 tractor, with what I understand to be almost 4000 pounds of lift, should pick up more.

I know that I would get the 7520 if I could do it again because I have a lot of trees that are still down from Katrina and that is a main focus of mine. I will be able to get most of that done with this tractor if I can get it set right. I will cut them into shorter lengths. I wanted the 84 inch root grapple in order to have the entire width of the tractor covered in the front. I would have gotten one that was not so wide to keep weight down if I had known that this tractor was going to have problems lifting.

A friend was loading 18 foot logs with a skid steed with a grapple like this but I believe that the skid steer is more powerful than this tractor with a much greater flow. My point on the 7520 is that it is 17 GPM with a much higher lift capacity and this is 11 and 17 would be closer to the GPM of the skid steer.

I am happy with the 6530 for other work but I also needed to do this clean up and thought that it would do it. I still have hope.

As for the idle speed and getting off the clutch I have to start my dig earlier and that makes for a big hole but I did it on that stump but there won't be many others that I will attempt that are that size, just too big of a hole and too hard on tractor. For one thing I can not begin to see the narrow stump bucket from the tractor seat. It can be seen very well from the seat of a skid steer and one can work with it fine, plus more lift power.

Thanks

GPM (gallons per minute) has to do with the hydraulic system speed, not power. PSI (pounds per square inch) has to do with hydraulic power. Skidsteers may or may not have more hydraulic PSI than your tractor, but also skidsteer loader arms are short which helps with the lifting leverage. The lift capacity of your Mahindra loader is measured at the pivot pins and could well be 800 to a 1000 pounds less at the front of your grapple, also deduct the thousand pounds your root grapple weighs and you don't have to much left. Have the pressure tested at your loader quick disconnects. The pressure should be in the neiborhood of 2600 psi. Good luck with it.

Hi,

Thanks. I will get it checked soon.

My Thought on the 7520 and the 17 GPM is that it would run skid steer equipment better. One example would be the skid steer front grass cutter which requires a large flow to turn the blades. I do not have one but would like to be able to cut in front.

My other thought on the 7520 is that it does have a higher lift rating. I believe that I am out of my league with this 84 inch root grapple on a 65 HP tractor, the weight being 1000 pounds before anything is added to the grapple.

Link to grapple:

Skid Steer Extreme Root Grapple

It is a very nice grapple and 60 HP was the recommendation. I never thought that there would be a question about the lift capacity of the 65HP tractor I bought when it comes to this grapple. I guess that I assumed that this tractor was as good as a skid steer when it came to lifting this grapple loaded. I saw large logs being loaded with a skid steer and thought that this tractor would be at least as good or better.

The Stump Bucket is much lighter.

I do believe that the breakout on my loader is too low. It does not even try to lift before breaking out.

GPM is speed PSI is pressure or power.

Skid steers now all have 3000 psi or more other than New Holland

The size cylinder is the real determining factor in how much breakout you have. The size cylinder is bigger on larger tractors with more GPM. Because most companies don't want to overload compact tractors and they want to achieve a certain cycle speed on a loader the more gpm you have the more breakout you will have due to larger cylinders.

The limiting factor to how much you can lift with any tractor is almost always the breakout force not the actual lift capacity.

Your application is all about the breakout force.

Obviously a tractor with only 8 or 9 speeds and can still run 18-20 mph is not going to have as low a gears. 1/2 a mile an hour slower is huge when your low speed is probably 1 mph. Its not creepin but its 30% - 50% slower.

You need a really slow speed and a loader with great breakout and decent lift to do what you are doing or rent a big Track Machine Takeuchi TL150 or if you have to settle for a Bobcat go with a T300 or bigger.

Good Luck
