They are heavy, but very nice.. I got mine last year brand new at a farm auction for $1800. I installed it myself, which was fairly easy, hardest part was routing and finding places to hide all the wiring. After I installed it I raised it up and my front squatted so much I thought there is no way this will work. I then moved my front shocks to the outer holes, cranked the shock adjustment to the stiffest setting, put 25 pounds of air in my front tires, and put 4 sand bags in the bed. I plowed all last year this way with no issues, but it was still squatting my front end more than I like.
This year I installed highlifter heavy duty springs on the front and still have the shock adjustment turned all the way up on the outer holes, 25 pounds of air in the front tires, and found a 400-500lb weight for the bed. We haven't had any snow to plow this year (knock on wood), but if feels a lot better. The blade raises higher, less body roll when turning, and seems to steer easier.
Long story short, if I had to pay full price for it, I would have bought the poly straight boss blade instead. If someone were to offer to trade me straight across for a poly blade and I didn't have to redo the wiring I'd probably do it. The stake feature comes in handy ever now and then, but all the weight I've added to the ranger will most likely catch up with me before too long.
Hope this helps you out.
