However, there are several simple guidelines which you should keep in mind while looking for the best lawn mower. With the right mower, you will keep your lawn looking greener, fresh and attractive.

5-blade reel vs. 7-blade reel

The five-blade push reel mowers are known to be better for taller grass such as fescue, while the seven-blade reel lawn mowers that are designed to handle the bent type grasses such as St. Augustine and Bermuda more efficiently.

Ease of pushing and cutting width

However, the reel mowers require extra maintenance as they come with many moving parts.

Lawn Mower Handle

Some reel-type mowers are designed with a straight horizontal handle while others come with a loop design for the handles. This might be a preference, but it is easier to push than the straight horizontal type.
