I'm looking for comments and thoughts for the John Deere Frontier RB2284 Rear Blade.  I have a 72" Land Pride and I'm thinking of going to a wider and heavier blade.  This is much heavier than my current blade and I don't have rear hydraulics.  Is this too heavy to adjust without hydraulics?  My tractor is a JD 4720 and I need a moderately heavy duty blade.
Thank you for any help you might provide me.
