Harry,
I agree with part of what you say about the GD/Hydro thing, but just because "IH discovered", as you say, that 9 out of 10 people bought hydros, does not mean the hydro is better. I would be willing to bet those 9 out of 10 had no idea of, and really didn't care about, the the mechanics of a gear drive or a hydro, didn't care about the number of ratios, or the slightly higher to speed, or the fact that the hydro could foam the Hy-Tran when worked really hard, etc., they bought them because it was something new, it was a garden tractor with an "automatic" transmission, just like their car. The begining of the hydros was a time that more and more people were buying autos with automatic transmissions rather than standard shift transmissions, buying them for convenience, for ease of use, not because they were better, more probably because we were lazy. Each has it good point and bad points, and it is all up to the individual to determine which best suits his/her needs. I like my gear drives, but also think a 149 is one of the best all around use models IH ever built. I plow with a gear drive, I mow my grass with a zero turn, but liked my 107 better for mowing (robbed the engine for a project) because of the trees, flower beds and other stuff that was/is in the way, a hydro was easier. Mowing open areas I would choose a GD. But mine or your likes or dislikes, does not make one better than the other. They each have their place, and it is up to the individual to determine which is best for them based on the facts we provide them, not just on our preference.
