Lawn Mower Buying Guide

Firstly, you must understand your yard

Think of your lawn as a tennis court. A full-size court would be a medium lawn, half the court or less would be a small lawn. Anything bigger is a large lawn.

  • Small lawn (up to 100 sq m): electric and cordless lawn mowers.
  • Medium lawn (100 – 250 sq m): electric, cordless and petrol lawn mowers.
  • Large lawn (250+ sq m): petrol lawn mowers.

By Type

  • Push mower: ideal for flat small yard. It requires the user to push a motorized blade cutter with wheels across the lawn, it is more budgeted than the others.
  • Self-propelled mower: Mowers offer both front and rear wheel drive to better suit your yard. You simply just need to walk behind the it to control its path. If you feel like you spend way too much time mowing your yard with a push mower, a self-propelled mower could dramatically reduce the time spent on it. You may need to consider one more detail: is your yard flat or hilly? The difference could determine whether you choose rear-drive or front-drive self-propelled mower. A rear-drive self-propelled mower designed for hills pulls the rear wheels instead of the front wheels. A front-drive self-propelled version pulls the front wheels and works best on flat land.
  • A ride-on mower: may be a better choice for those with larger acreage, ff your lawn is larger than ¾ acres you may want to consider a ride-on one.

By Gas or electric:

  • Gas mowers have longer run-time and offer more power than electric, but they can be messy and require more maintenance than their electric counterparts.
  • Electric mowers can be corded or cordless and are much cleaner to operate than gas, but unless you have two batteries (for cordless), there is always a chance you could run out of juice. Of course, with a corded model you're limited by the length of your cord, which can be a nuisance to mow around.

By cutting type

  • Side-Discharge mower: Some of the stuff we cut just can't be mulched. Using side discharging and a block off plate because it is more versatile. A side discharge mower can mow in nearly all conditions, fast mowing & high quality cut. But, the clipping discharge to outside, so it will fit for a large area.
  • Mulching mower: which cuts the clippings into very fine pieces which break down and release nutrients back into the soil. Mulching is preferred in tight area with some specific conditions (the lawn is not too wet and not too long), it can provide nutrients to the lawn but it will reduced mowing speeds and can have issues if not monitored.
  • Bagging mower: which collects clippings into a bag which is disposed of with yard waste. Bagging can mow in nearly all conditions, completely removes all debris, fast mowing & high quality cut. But, you must dispose of clippings.
