Am purchasing a boxblade soon. Looking at a Landpride 7ft heavy duty (1119lbs.) Dealer seemed concerned at first about the size. Have 45 hp 4wd with ag tires. Shows me a lighter duty (593 lbs)7 footer and an even lighter 6 ft(504 lbs.) that is in stock. Will sell the instock 7 medium duty for $1150. Can't remember what he said it retails for. From reading here, weight seems to be a good thing for boxblades. Will be moving a lot of dirt with clay and maintaining drives. Is the heavy blade too much for my situation? Landpride literature shows 65 hp rating max for the heavy duty and 40hp max for the medium duty. Is the price a good one for the lighter one that he wants to sell that is in stock? Didn't get a price yet for the heavy one. Would prefer the heavy one if it'll work.
