is there a market for them? with hydros priced not all that much higher when you take into consideration the life span of a w/b is there still a commercial market? i think the bigger guys who have several crews might get them because they are cheaper, lighter, hard to hurt, and they don't use them themselves anyway. Am i right or wrong? i want one just because i never had one and want it for ditches i think it would be great where a lighter posi-traction mower would be needed but i'm solo and buying a non-hydro seems - - - i can't justify it. are they obsolete??
