Correction, I got Fosters confused with Brookside.
I had a friend buy from Brookside but I had to almost beg them for a quote. My feeling was that they were only interested in selling SCUTS, CUTs and lawnmowers. I was looking for Ag. That seems to be the only parts they stock as well, but I've only tried to deal with their NW store.
According to their sales people Fosters does sell quite a few tractors to out-of-the-area/State folks. They will deal with you. Hockley is limited on what they can sell regarding Ag implements, that's why I go to CP Navasota. They are great to deal with as well.
