I am thinking about getting a hydro walk behind this fall or next spring. I have always used gear drives, and am wondering if I'll actually see a 30% increase in productivity like the catalogs claim. I will admit that I experience some belt slippage in the spring, but as far as reverse goes, I really only use it to get the machine off of the trailer. I usually run in higher gears, and manage to keep mowing in a forward direction. I plan on getting the same deck size I use now, and am finding it hard to believe that if a lawn takes 35 min. now, that it will only take 25 min. just because I got a hydro???? I thought I'd ask you guys because I find catalogs to be inherently full of hype. I would just as soon spend the $$$ on a rider but my lawns are to hilly, so I'm looking for any way I can get more done with less fatigue.
