Tractor is a 2520 26hp/20 HP@ PTO with HST. Only issue that I've had with the mower is breaking the soft bolts that I use for the shear pin. I think that it calls for Grade 5 and I am using something softer. This only happens when I first engage the PTO - even at low RPMs and the mower off the ground. I need to either get the Grade 5 bolts or better yet a slip clutch.
Maybe you need to just let the clutch out slower? I have never seen a shear bolt break on start up at an idle... that doesn't make sence.
