    Customer Review: AR Digital Wireless Transmission Hub Review
    This is a great way to go if you don't want to run speaker wires to the back of your listening room. Don't know if it would satisfy a true audiophile, but it works great for my 7.1 system. It really makes movies into surround sound.
    Customer Review: Works perfectly, no problems at all
    I got this to use with my Wireless Digital Headset. It hooked up perfectly and I've had no problems at all. I like that I don't have to tune in to it, my headset picks it up automatically. The sound it's sending to my headset is crystal clear. The only reason I give this 4 out of 5 stars is that I'm not happy that the receiver is separate from the headset.


    If you have a relatively large garden, you'll save a lot of time mowing your lawn if you buy a garden tractor. The tractor's cutting deck can cut twice as much as a normal push mower in one pass, and since the operator is sitting in a seat there's no need for physical strength.

    When purchasing a lawn tractor, there are a few features that you'll want to look for:

    Can the seated operator switch automatically between side discharging, mulching and bagging functions?

    Does it have front-wheel drive, or four-wheel drive?

    What is the turning radius?

    Automatic transmission? Cruise control?

    How noisy is the engine?

    Safety concerns

    The average push lawn mower is dangerous in its own right. Objects can be kicked up by the blades and hit the operator in the face. If the blades jam, careless operators try to clear the jam with their fingers, sometimes without turning off the mower...and bang go a couple of fingers. Therefore it's always a good idea to wear eye and ear protection, and always use a tool to clear out jammed grass or leaves.

    The same safety issues apply to lawn tractors. When it comes to lawn tractors, a piece of rock or wood perhaps won't come flying back at you - but it may hit an innocent bystander. Therefore a good rule of thumb is to not do any mowing at all when there are people about.

    Do you have to mow a slope? That's just about the most dangerous thing you can do...many's the hapless operator who has been pinned under an upturned mower because the slope was too steep and the lawn tractor too heavy, or with a bad center of gravity. Indeed, the best thing to do with a slope is to get rid of it - terrace it with various flower beds, or plant ground cover or ornamental grasses that don't require mowing.

    Precautions
    If you've got a lot of trees, scout the yard before you start mowing and remove any broken branches, any noticeable rocks that somehow have made it in to your yard, etc.

    Wear safety glasses, ear protectors, and stout shoes - not tennis shoes.

    If someone, in particular a small child, comes within five feet of the mower - turn it off immediately. Better still, do your mowing when there's no chance that you'll have an audience. And never take a passenger. Mowing needs all your concentration.

    Familiarity breeds contempt. That's an old cliche but cliches become cliches because they are true! If you've been operating the same old lawn mower for a few years, you may become a bit careless and not take proper precautions once in a while - because you're pressed for time, because you want to hurry up and do something else, or what have you. It's on those occasions that accidents will happen.

    So always give your lawn tractor the respect that such a big, and potentially dangerous, machine deserves.
