The GT5000 sales guy left me a bit confused on the front snow blade, front dozer blade, and rear grader blade. He said the snow blade and dozer blade are different (though they sure look the same in the catalog) and implied the dozer blade was heavier duty (he didn't differentiate between the blade and the mounting system). If so, why does Sears sell both blades? Is it because the snow blade is for both lawn/garden tractors but the dozer blade is only for garden tractors? The sales guy said if I tried to use the snow blade to move dirt/gravel, I would end up bending the frame where the snow blade attaches, which implies that the mounting differs between the two. Also, I'm getting differing opinions on whether the front dozer blade can be used at the same time as the mowing deck, because apparently they use the same lift mechanism? Seems like people would want to be able to use both. I'd hate to have to remove the mowing deck each time I want to use the dozer blade. Finally, people tell me a rear-pulled grader blade (or box scraper, for that matter) has more power than a front-pushed dozer blade. If so, wouldn't it be better to use the rear grader blade for deep snow, say, 12" deep? Or would this not work because then the tractor itself would not get enough traction in the unplowed snow? I was debating between the GT5000 and the DYT4000, but ever since I found that the front and rear mounting systems are different on the garden tractors from the lawn tractors, I decided I should pay the extra and go for the GT5000. Plus, there's the future Johnny Dump. Can anyone help clarify? Thanks!
