Now relocated to a rural environment, I'm learning about all sorts of new tools and objects I'd had no exposure to in the city. I've just purchased, and am now familiarizing myself with, a lawn tractor/riding mower. While researching the required maintenance routines I came across the Mo-Jack and the Jungle Jack, two very different solutions to the same problem.

A lawn tractor has a deck beneath it housing the cutting blades. These blades periodically need to be sharpened. Because the blades are attached from underneath, this presents the problem of how to access them. A non-professional user like myself can take the time to disconnect the deck, slide it out, flip it over and work on it that way. But a professional landscaper or mechanic, for whom time is money, would desire a faster way to access the bottom of a machine.
The MoJack design seems more idiot-proof to me, as the weight of the vehicle rests on the suspension as it is raised. (Even a light-duty lawn tractor like mine weighs 600 pounds). I like the simplicity and greater speed of the Jungle Jack, but obviously greater care must be taken with the connection point.
Core77 readers who use/maintain lawn tractors, if you've got any efficiency tips or things you'd like me to research/write about, please sound off; I'll soon be able to speak your language.
