You've already done the difficult stuff. Seeding. Watering. Fertilizing.
Now, the fun begins... harvesting your hard work while getting a sun tan.
There's no reason to outsource your lawn mowing if you purchase the proper equipment in the first place.
Basically, there are three types of lawn mowers designed to decapitate grass:

Walk-Behind Mowers
Ideal for small- to mid-sized suburban lawns, walk-behind mowers come in a variety of flavors: reel, electric, cordless or gas-powered.
Ultimately, you need to decide if you want to push the lawn mower or do you want it to propel itself.
Riding Mowers
If you've got a larger property or just don't want to walk, a
riding lawnmower is a terrific choice. With cutting widths ranging from 27" - 66", you can cut a lot of grass at a time.
There are four different styles of riding mowers:
rear engine riders,
lawn tractors,
garden tractors and
zero turn mowers.
Tow-Behind Mowers
Whether you're mowing the fairways of a golf course or taming the wild brambles of an overgrown field, a
tow-behind mower is the perfect companion to your existing ATV or tractor.
Towable mowers come in several styles:
gang reel mowers,
trail mowers and
trail cutters.
