I've got an L3540 and I'm looking at rear blades for it. Im not sure how wide is too wide. Is 72 enough or am I better off with an 84"? I've looked at the land pride 1572', but a 2684 was also mentioned by a dealer. A bit more expensive but heavier, has the ability to angle. And offset I believe. I'm Looking to regrade dirt driveway occasionally and probably use with snow cleanup. Thanks.
Rear blade, how big is too big?

If you want to get some work done forget about those 2 models. At under 400lbs, the RB2684 is simply not heavy enough and the offset is a joke. Unbolt and slide the blade sideways up to 12". 
Get an RB3784. Much better blade and it actually will work for you instead of just bouncing along top the surface.
Just need to remember, you get what you pay for. Go cheap, you get cheap. Grading implements are not something where you want a light weight, low cost implement. You want-need weight, and that costs money.

I think my 3560 is about the same size as yours, and the manual recommends 72". I got a Woods blade, HBL 72-2, and the one that does offset is much easier to swivel and adjust for other angle changes etc than the cheaper ones. Just pull big pins and shove it, no bolts to undo. It is heavier, maybe heavier than I needed, but I found last winter that I just used the perpendicular position, and the offset, which angled it at the same time, so only one pin to pull in the cold. It also is constructed so you can swivel to reverse it entirely for convex side forward if you want. Some blade types, and especially if longer hang up on the rear wheels.
The problem with a 72" rear blade is there are times when it works best to have the blade at a 45* angle. A 72" blade at a 45* angle does not cover the tracks of the tractor where as an 84" blade does.
Pin or hydraulic offset is the only way to go.
Bolt and slide offset, better than not having it, but that is about it.

I got an 84" blade for my L3750 and it just barely covers the rear tires when angled all the way. 72" was too short.
Thanks guys. I guess my only unknown is if I really need the extra weight and cost associated by going with the 2684 or 3784 models. I'm going to drag my driveway a few times a year and use it with snow removal. Haven't found much in way of used so new prices range from 700ish to 1500ish depending on model.
