Alot of useful lawn care products have showed up in the past few years. In addition to the mowers that have been introduced, you also have things like the stick edger, the Power Pruner, and extended reach hedge trimmer. All of these are extremely useful to the maintenance industry.<p>There have also been a number of not so good ideas. I may be the crazy one here but I beleive Encore takes the prize, at least most recently. For their walkbehinds they have introduced a removable gas tank. The logic behind this is, it is easier to change the gas tanks for refueling than simply refueling the tank on the mower. They claim less fuel spills (better for the enviroment) and quicker refueling. What? You don't change the deck on your mower when ya need blades. You don't change the engine when it's time to change the oil, just so you can avoid an oil spill. Geez, if you are having all this trouble refueling, have someone give you some lessons on putting gas in a container! You have to put gas in the extra tank too, how do you avoid spilling it all over the place then?<p>I actually looked at the new Encore Prowler rider. The dealer showed me the "cool" removable gas tank on the walk behind and I thought better of buying a new Encore. If the removable gas tank is the best they can come up with, maybe there are better choices.
