Lifting Limit

[LD1]

Is that a SGC1560 grapple? If so that thing is a beast at 820#(100# more if its a 72" grapple). So that is costing you some capacity, because a ~400# grapple is more than enough for a MX.

That said....I agree a little curl back would help, then lift

Quite honestly stump does not look that big..... Probably need to up RPM to get more hydraulic power...
Do you have rear ballast?....
If you have the LA 1065 loader you should have about 1691 pounds lift ...

Actually if you understand the specs, the 1600# is to max height.

At ground level.....3100# at 500mm is the spec (the breakout force). And to a midpoint....bout 5' high.....the lift capacity should be somewhere in between. Somewhere around 2300-2400#.

But having a grapple that is ~400-500# heavier than the standard bucket hurts the net capacity

That is why I quoted the 1600 pounds, figured it was limits was able to lift, and doubt stump is that heavy...

A fresh stump with dirt embedded in the rootball is surprisingly heavy. If it doesn't want to budge, your tractor is telling you to back off.
