Best petrol chainsaw 2026: the complete buying guide

Anyone who regularly fells trees, cuts firewood or manages a large property with mature trees eventually ends up looking at a petrol chainsaw: the only type that runs completely independent of mains power and delivers enough grunt for solid trunks. Unlike a battery or corded electric chainsaw, a petrol model keeps going all day, with no cable, extension cord or spare battery. This guide walks through the real buying criteria, from engine displacement to safety features, and covers six practical picks for different kinds of use. Not sure yet how many trees or hedges your property actually holds? It helps to map out your garden first on gardenworld.app before investing in a petrol chainsaw.

What to look for before you buy

A petrol chainsaw costs, depending on power, somewhere between 150 and 1,000 euros, so it pays to look past the price tag.

Engine displacement (cc) Entry-level models have a displacement of 30 to 38 cc, more than enough for pruning waste and thinner trunks. Mid-range models with 40 to 45 cc cut effortlessly through most garden trees and firewood, while professional models from 50 to 70 cc are built for forestry work and felling large trees.

Bar length The bar length determines the maximum trunk diameter you can cut through in one pass. For garden use, 35 to 40 centimetres is enough, for firewood and medium-sized trees choose 40 to 45 centimetres, and for felling large trees a bar of 50 centimetres or more is standard.

Chain brake and safety features A chain brake that locks the chain automatically on kickback is essential on a petrol chainsaw. Also check for a chain catcher, a throttle lockout that prevents accidental acceleration, and a reduced-kickback bar tip that lowers the risk of kickback.

Vibration dampening Prolonged cutting with a petrol engine causes vibration that can eventually lead to hand-arm vibration syndrome. Good models have rubber decoupling between engine and handles, which noticeably reduces the vibration transmitted.

Starting system An easy-start system with reduced pull force on the starter cord saves a lot of frustration, especially in cold weather. Also check for a decompression valve, which considerably eases starting on larger engines.

Weight Petrol chainsaws typically weigh between 4 and 7 kilograms including fuel and bar. For prolonged use, a lighter model is more comfortable, though as a rule you should never cut above shoulder height with any chainsaw.

Price range Entry-level models start around 150 to 250 euros, mid-range models cost 300 to 500 euros, and professional forestry models run up to 600 to 1,000 euros or more.

Safety first

A chainsaw is the most dangerous piece of garden equipment most people will ever hold, and kickback is the most commonly cited cause of serious accidents. Always wear full protective gear: a helmet with visor, hearing protection, chainsaw trousers or chaps rated to stop a moving chain, sturdy steel-toe boots and cut-resistant gloves. Check the chain tension and the bar oil level before every use, and make sure the chain brake operates smoothly. Never cut alone without someone knowing where you are, always hold the saw firmly with both hands, and never cut with the bar tip in wood, since that is the leading cause of kickback. If in doubt, leave felling large trees to a certified arborist.

Entry-level petrol chainsaw

For light pruning and thinner trunks, an entry-level petrol chainsaw is the obvious first choice: compact, with a displacement of 30 to 38 cc and more than enough power for most garden jobs.

Mid-range petrol chainsaw

For cutting firewood and medium-sized garden trees, a mid-range petrol chainsaw is the most popular option: with 40 to 45 cc and a bar of 40 to 45 centimetres, it cuts through most common trunks with ease.

Professional petrol chainsaw

For felling large trees or intensive forestry work, a professional petrol chainsaw is essential: from 50 cc and with a bar up to 60 centimetres, this is the type landscapers and arborists use daily.

Petrol chainsaw with chain brake and vibration dampening

For anyone who puts safety and comfort first, a petrol chainsaw with chain brake and vibration dampening is the smartest choice: an automatic chain brake and rubber decoupling make long cutting sessions noticeably safer and less tiring.

Lightweight petrol chainsaw

Anyone who prefers a compact, light model should pick a lightweight petrol chainsaw: often under 4.5 kilograms including the bar, comfortable for occasional use or smaller hands.

Petrol chainsaw with a long bar

For felling thick trunks, a petrol chainsaw with a long bar is the right choice: at 50 centimetres or more, it cuts through trunks in one pass where a shorter bar falls short.

Maintenance for your petrol chainsaw

Clean the air filter regularly and replace the spark plug on time, since a clogged filter or worn plug costs power and increases fuel consumption. Always mix petrol and two-stroke oil in the ratio specified by the manufacturer, and use the mix within a few weeks, since old fuel loses its properties. Sharpen the chain regularly or have it done, since a dull chain actually increases the risk of kickback because you need to apply more force. Drain the tank before storing the saw for an extended period, to prevent the carburetor from gumming up.

Common mistakes

The most common mistake is choosing a saw that is underpowered for the job at hand, causing the engine to be overworked when felling thick trunks. A second mistake is not checking chain tension and oil level before use, which wears out the bar and chain faster. Finally, many users work without full protective gear, even though a petrol chainsaw carries the highest risk of serious injury of any garden tool.

Comparison

Which petrol chainsaw suits your garden?

If you have a small garden with the occasional bit of pruning, an entry-level model is more than enough. For a mid-sized property with fruit trees or an annual stock of firewood, a mid-range model is the smartest choice. If you manage a large property with mature trees or regularly need to fell large trees, a professional model with a long bar quickly pays for itself in power and time saved.

Frequently asked questions

Is a petrol chainsaw better than a battery or corded electric chainsaw? For occasional use close to home, a battery or corded electric chainsaw works perfectly well. If you regularly work far from an outlet or need to fell large trees, a petrol chainsaw offers more power and unlimited runtime.

What fuel mix ratio do I use for a petrol chainsaw? Most two-stroke engines require a mix ratio between 1:40 and 1:50, but always check the manual for your specific model, since this varies by manufacturer.

How often should I sharpen the chain? With regular use, sharpening every few cutting sessions is wise, or as soon as you notice the saw producing fine dust instead of coarser chips, a sign the chain is going dull.

Do I need a permit to fell trees with a petrol chainsaw? That depends on the tree and your local authority: many municipalities require a permit for felling larger trees, so check with your local council beforehand.

Conclusion

A petrol chainsaw is the most powerful and independent choice for anyone who regularly fells trees, cuts firewood or maintains a large property, as long as you choose the right displacement and bar length and take safety seriously. Choose based on the work you mostly do, always wear full protective gear, and keep the filter, spark plug and chain well maintained.
