Frequently Asked Questions (FAQs)

1. What is a petrol rotary lawn mower?

The petrol rotary lawnmower is the iconic machine that most of us recognise as a 'proper' lawnmower. They are designed to cover a range of grass-cutting tasks rather than specialising in one particular area of lawn-care making them suitable for almost all homeowners.

2. Which is better cylinder or rotary mower?

A quality cylinder lawnmower can 'shave' as close as 3/16” and can be raised up to about an inch without too much loss of mowing quality. A typical rotary lawnmower on the other hand won't go much below 1/2” and can be raised up to perhaps 3” or even 4” without deterioration in cut.

3. Is a rotary mower better?

It's much more precise and even. There's no tearing or ripping. Rotary mowers are like throwing a knife at your lawn, as opposed to the scissor-like precision of a reel mower. The push reel mower will cleanly slice through your grass, giving it an overall tidier look than rotary lawn mowers.

4. How much does a rotary mower cost?

The average price of a lawn mower is $1,068. That overall average price includes reel mowers with an average cost of $104, walk-behind mowers with an average cost of $363, riding mowers with an average cost of $2,450, and robot lawn mowers with an average cost of $1,470.
