When buying a new lawnmower, you don't want to consider just price alone; the cheapest model may mean lots of extra work to get your lawn cut and a mower that isn't strong enough to tackle the tough grass on your property. On the other hand, the most expensive lawnmower may offer features you'll never need and may actually be too big for your particular lawn. Note a few things to consider when buying a new lawnmower so you know you get one that you'll appreciate for many years to come.

Lawn terrain

Unless your lawn is flat like a golf course, you probably want a self-propelled lawnmower, or a riding mower. Trying to manually push a mower up hills can be difficult if not downright impossible. Consider if your property has hills, valleys, rough grass, or any other terrain that is difficult for you to push a lawnmower over, and choose one that does some of the work for you instead.

A fuel-powered mower will also usually be stronger than an electric mower, so you may need one of these for a lawn with rough terrain including tall weeds and thick grass. You'll need to note the maintenance required for these, as mentioned below. 

Maintenance

A lawnmower that runs on fuel, either diesel or standard petrol, will usually need more maintenance than one that runs on electricity or with a battery. If you're not comfortable changing the oil of a lawnmower and having to clean out a fuel-powered engine, opt for a simpler model that works with electricity or a battery. A mower that runs on standard petrol will need the spark plugs changed, and of course you need to store the fuel for these mowers, so that too is a concern.

Transmission

With a manual transmission, you may need to switch gears on flat ground to speed up and then again when on hills to have more control over the mower's speed and strength. Unless your lawn is very flat and your mower will rarely need the gears switched, you might opt for an automatic transmission so you don't need to guess which gear it should be in for the lawn you're cutting.

Size

The width of the cutting area is one thing to consider, but where and how will you store your lawnmower? Can it be put in the garage next to your car without hitting it, and while leaving room for sporting goods and whatever else is in there? Can a riding lawnmower fit in your shed? Be sure you've thought about this before you choose the biggest model you can afford; take measurements of your shed and it's door or the space in your garage before you shop, if needed.
