What to Look for in a Lawn Mower Under $400

Four hundred dollars isn’t a small amount, and so you will need the best self-propelled lawn mower for trimming and manicuring your yard. All the self-propelled lawn mowers under $400 are good, but there are the best: those with excellent features designed to make your mowing experience easier. So, since you will spend a good amount, you need to understand a top-quality self-propelled lawnmower’s vital features.

Height adjustment

Your lawn mower cutting height adjustment describes the grass height from the ground that the mower will cut. The cutting height can be easily adjusted by pulling the height adjustment lever. If you set a short height, the short grass might not withstand excessive heat or drought, while too long grass may accumulate thatch that can get in the way of fertilizer and water.

Grass disposal options

It is crucial to consider the cutting deck discharge design. Where will the grass go once it’s cut? Most self-propelled lawn mowers have three-in-one functionality giving you the options to mulch, rear bag, or eject grass on the side. These three options make your mowing experience better, with the mulching function making your lawn healthier and thicker. If your lawnmower comes with a bag less discharge system, it allows you to mow the whole yard without stopping to empty the bag. The only problem is that it creates build-ups of the cut grass in the yard.

Drive system

Self-propelled lawn mowers run on drive systems like rear-wheel and front-wheel drive. Every drive system has its benefits, so let’s look at the drive systems.

  • Rear-wheel drive – These kinds of lawnmowers are powerful and are perfect for hilly lawns. They have improved traction and unnecessary intervention.
  • Front-wheel drive – These types of machines work best in flat areas. When the front wheels are raised off the ground, especially when mowing hills, the mower stops moving, they are easy to turn around in tight corners or when it’s time to reverse course.

Speed systems

Many lawnmowers operate at a consistent speed, which enables precise cuts. Moreover, the lawn is thicker, a lawnmower with fast speed may not cut the lawn as expected.

However, most of the self-propelled lawn mowers run on variable speed, which gives the operator full control of their mowing speed. It allows you to change the speed depending on the type of terrain or the grass thickness. A variable speed will be a better choice if your lawn has thicker grass and uneven grounds.


Although you won’t be pushing the self-propelled mower, you have to maneuver it around the lawn or up and down the hill. So, since these types of mowers are more massive than the push mowers due to the push mowers, it is crucial to check their weight when purchasing a lawnmower. You should look for a mower with 60 to 90 pounds.

Frequently Asked Questions (FAQs)
