I notice that the NH specs are given at 31.5" out in bucket center....I'll have to look, but I believe that the breakout force of the 18LA loader is 5000# at pivot point.

Looks to me that on the loaders for the TN 75,85,95 the lift at 59" falls short of the ML275 at full height. These NH tractors have the same form factor as the 7520. You cant lift what the 7520 does to full height safely except under very controlled circumstances. My interpretation is the TNs cant lift it to full height at all. From the fast times of the TN loaders it seems that they must have smaller cylinders. That would explain a lot.

That's what I was thinking Larry. Have to measure the cylinders, and know the psi the systems are operating at. I believe that NH TN70/75 is 2755psi. Been looking for the Mahindra 6000-7520 system pressure, and need to look at the hydraulic pump output in gals per minute. Thanks for checking in on this for me.

Found it for the Mahindras.....11gpm for the 6500, 17gpm for the 7520. Now would like to know psi.

I just happened to have the working PSI of the 7520, near by. The book says 2690.

As Galen says, the tractor relief is set at about 2700psi. The loader relief tho, I believe, [according to KMW spec] is 2450. Lift cyls are 3". 7520 should do 4.9s lift at 2500RPM/17gpm, but is not published as being that fast. Mine will do full lift in 5s flat. Slower than TN loaders, but 3900# to 11' at the pins. Not w/o ballast.
