Weight and height for 3 point

[leeco]

Has anyone used a 3 Point Hitch Scissor High Lift, Hay Lift with a Bale Spear ?

I have a B7510 and want to know if I would be able to use these two attachments to lift square bales of hay that weigh about 900 pounds and if so how high could I lift them.

I know a 7510 is a little more tractor than a 7100 is but the 3pt on my 7100 wouldn't lift a 4672 Kubota BH off the ground. It weighed about 900 lbs or so and as soon as I hit the lift it would open the relief valve up. I wouldn't want to try and handle bales that heavy with a B series tractor.

The very fact you mention "how high" seems to suggest you have thoughts for lifting more than a few inches from the ground?
Even if your B7510 could lift a 900lbs bale you would need quite a counter weight on the front and plenty of bog roll at the ready when on the move

B7100,

I have that data sheet on the B7510 and it says that the 3point can lift 1356 pounds. I am hoping to stack a 900 pound bale onto another bale so I would need to lift it about 3 feet. Between you and Bulldog it seems like it would not be a good idea. Here is a link to the implement I was thinking of using.

Looks like I might have to upgrade to a bigger tractor

I understand wanting to get everything out of your tractor. I do things with my L 3000 that I really shouldn't do. Loading hay is one of the worst chances I take.
If you tractor can lift 1300 @ 24" then it probably is over 2000 lbs at the lift point. So roughly you loose 40% capacity @ 24". I looked at the link you posted. Nice looking implement. I did notice a few things about it though. It seems since it uses a top link that it sets the load back another 24". If this makes you loose another 40% you'll be down to around 800 lbs and don't even have a bale speer on it yet. Add the speer and your setting the load back even more.
I'm just making a guess using my own experience with things like this, I bet you won't be able to lift over 500 lbs with the weight sitting so far back from the tractor. Another thought is with the weight that far back I bet you can't keep the front tires on the ground.
I remember this about my brothers B 7500. With the loader off and a 4' bushhog on the back I could grab the brush guard and pick the front tires off the ground by hand.

Bottom line, I really think you will be taking a big chance trying to use that implement on a B 7510. I don't want to hear about one of my orange brothers getting hurt or killed by doing something that a little advise could have prevented. Maybe some of the other guys can help you out more but I don't think it would be a safe way for you to move hay. Good luck with whatever you deside to do.

I believe if you take a look at them, the 3-point scissor lift accessories you're talking about are intended only for tractors with category II 3-point hitch.
I was checking into one for my M4500 to move round bales, but it is only category I.
Makes sense since they're really seriously multiplying the force on the top-link mounting point in a direction it is not intended for on most cat I 3-points(many cat II top link mounts are "solid" rather than the hinged "draft control" types on cat I systems). Bottom line, I thought it looked like a good way to break my 3-point top-link mount. If it was a solid mount... maybe, but mine has draft control.
