I have 2 newer style b7100 HST one with loader and one as a mower. Always loved the 7100. I picked up a B1750 and so far really kinda liking it a little more. Basically it seems like a 7100 with a few upgrades such as power steering, few more horsepower, and an actual water pump and weighs a few more pounds. So I'm thinking of selling both of the 7100 and find another 1750 to replace them. Any reason I shouldn't do that other than the 7100 is just an awesome machine?
