I went to fold the ROPS on my new 2520 last night and had to use a hammer and punch to get the pins out. Once out, I noticed some generous misalignment between one set of the holes. The pin on one side slid right back in, but the other wasn't even close. I had to use a 3lb sledge and a block of wood to get it back in.
Is it just me or is this not optimum? Does your ROPS function the same way? I envisioned this being a tool free operation.
On a side note, I was also a little dismayed to notice that with the 46 backhoe mounted, the ROPS won't quite fold down far enough to put the pins in the down position. The roll bar hits the backhoe frame a mere few degrees before the pins could go in. Grrr.
