My (4) field tractors are all gear, and I wouldnt want a hydro for field use. For on the lawn, I have one hydro and one gear. These two machines really demonstrate the strengths/weaknesses of both transmission types. They are both the exactly the same hp, but the mower is about 20% wider on the gear tractor. In spite of that narrower mower, I can usually get the lawn cut faster with the hydro because that lets me perfectly match the ground speed to any conditions. The gear is always a little too fast or a little too slow for conditions. This time of year however, when the lawn needs cutting every 3-4 days, I prefer the gear even on the lawn, because it lets me get more of the engine's hp into the grass. Cutting thick spring grass takes a lot of hp. So right now, on a scale of 1-10, for cutting my lawn, the hydro gets a 5 and the gear gets a 7. When the grass slows down in the summer, the hydro gets a 9 and the gear gets a 5. Where a hydro excells, just think of the letter "L" : Lawnmowing, Loader use, and Landscaping.
