I got mine today for my JD 4110. Got the XL model (in green, of course). Took me (by myself) about an hour and a half to put it together and install it. Instructions were okay. I got it because my tractor won't fit in my shop with the ROPS up. The plan is to take the canopy off and flip it upside down, and lay it on the hood between the FEL arms before I drive into the shop (and of course fold the ROPS down). Pretty easy to do when I tried it today.
Regards,
Ira
