How many of you stay away from using push mowers? For those of you that stick to smaller lawns I know the push mower gets quite a bit of use, but for those doing large accounts with ditches or tight areas that you can't get the Z, what do you use? Push mower? Trimmer? Walk Behind? I've seen a lot of ppl around here w/ 2 ZTR's and no walk behind or push mower. I guess they trim where they can't get the Z, but wouldn't it be much faster if they used a walk behind or push mower at the least?
