First off let me say that I am not a commercial mower but we mow about 2 acres per week plus another 3 acres about every other week here on our farm. We are currently using an IH 184 Cub low-boy with a 60" deck but it is too slow so for next year I am looking at buying a commerical ZTR mower (need a commercial mower due to tall grass and rough ground) and mostly due to dealer service I have narrowed it down to either a JD 757 with a 54" deck or a Cub Cadet Tank M54. I honestly can't see much difference between the two on paper and from what I have read on here they both seem to be great mowers, has anybody on here ran them both? I think the Tank looks like a slightly heavier built mower but I think the 7-iron deck looks a little better than the Tank's. Are these mower's close enough to each other that I should just buy according to price or am I missing something. Here in rual Iowa commercial mowing is not a big business so I am limited to only a few brands of commerical mowers and these two will provide the best dealer support.
