So Rhino is a good (quality) implement... I'm assuming that is the price "New" (which you could still do better on), if that is used I don't think it a good deal... new maybe ok.... It looks like the Rhino CBX60 only weights 280lbs so that shouldn't be an issue
My only other caution is if I read your tractor specs right it is 57.1" wide so a 60" blade barely covers your tires track.... depending on a couple of things you way want to look wider... not sure the width of your driveway / roads you will maintain or the pitch, or crown but I have a 72" box blade on our 40 HP machine which is 68+" wide & I wish I had gone wider. The reason is in many areas where I have either drainage or culverts I can not get the box blade as close to the edge of the culverts as I need to (especially when I add some pitch to the blade).... just food for thought... you may want something a little wider
Also it is a box blade so you may want to look for a used one... no movable parts & not a lot of wearable parts so it is pretty easy to spot an abused one...
