I recently purchased a t7074 and really like it. But, I need it to be a snow mover and I'd like to put a set of chains on the back (I have them on the front). The back tires are 18.4 x 24 and are R4 industrials. When I look at the clearance between the sidewalls and the fenders I get concerned about the clearance. Have any of you put chains on this tractor? Any recommendations on chain style, size or brand? Thanks in advance.
