Just wondering how many of you trade or sell your main mower every 2 - 3 years & buys new. Thinking of doing just that, if I could get in the cycle. Thinking of selling my old chopper & gettting a new one to go with the new TORO WB I got earlier this season. Down time is rough now that my schedule is full. Not to mention repair costs. SO does trading / selling used mowers & buying new every 2-3 years work out well?
