Frequently Asked Questions (FAQs)

1. Is a 4-stroke lawn mower good?

Pros of a 4-stroke engine: More torque, the engine is quieter and more reliable. Last longer than a 2 stroke engine. You don't have to mix the oil and fuel. Runs cleaner than a 2 stroke, less pollution.

2. Is 2 stroke or 4-stroke lawn mower better?

Generally, a 2 stroke engine is much smaller, lighter weight, louder, smokier, and cheaper. A 4 stroke engine is more fuel-efficient and produces more torque. 4 stroke engines are also easier to start, more reliable, more powerful, and more expensive. Both engines are examples of internal combustion engines.

3. 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.

4. 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.
