A high-quality chain saw at a country site is not an excessive luxury, but a useful and necessary tool, without which most gardening and construction works cannot do. What kind of assistant to choose for quick harvesting of wood, trimming trees, building a roof?
At the next dealer conference of the StanleyBlack & Decker company, as usual, they demonstrated novelties. Including new models of battery garden equipment, in particular chain saws. One of them - the model DeWALT DCM575 from the FlexVolt series - we are especially interested in.
We tried it at work and estimated the cutting speed. According to subjective feelings, it is not worse than that of a chainsaw. Reviews of dealers, who also had a chance to experience the novelty, were also positive. Some of those present also noted that the tool not only saws quickly, but also holds the load perfectly. The engine does not reduce speed, if it is harder to press the handles.
Then the idea arose to conduct a comparative test and find out which saw is faster - battery or gasoline.
DeWALT or Stihl - Alien vs. Predator
As a competitor for this competition, we chose a chainsaw Stihl MS 180 with a power of 1.5 kW (2.1 hp). Why this particular model? First, it is one of the most popular chainsaws Stihl, very popular in Russia. That is, we compare it with something already well known for a long time. Secondly, the power of the cordless tools in the FlexVolt series is exactly one and a half kilowatts. That is, comparing "devoltovskuyu" chain saw with the "calm", we compare the model of the same power level.
Method and test course
Before testing, the saws were checked, the chains were corrected, so that it did not work out that one was working with a sharp chain, and the second - with a blunted one. We took the whole test on video. It shows that large sawdust is flying from both saws, not fine dust - and this is a sure sign that the teeth are sharp, and the chains are in a normal technical condition.
For the first stage of the test, we decided to buy a bar of 100 × 100 mm and made 10 cuts with each saw, fixing the work time. Here the Stihl 180 chainsaw is in the lead - it took 22 seconds for it to cut 10 times. The battery-powered DeWALT on the same amount of work took 27 seconds. There is a difference, but not very big, and one could already conclude that the “accumulator” would soon catch up with the petrol equipment in terms of performance.
But here we decided to complicate the task. They took six pieces of timber, put them together with a “package” of a total size of 300 × 200 mm and began to cut this package. And not in the way that, in general, it is necessary to work when the saw cuts only under its own weight, but at speed, that is, with decent pressure on the handles. And here the rechargeable saw showed that rumors of lower performance compared to the "gasoline" are somewhat exaggerated. It took 53 seconds for 5 cuts of a package (ie 30 “single” cuts), Stihl has 180 minutes. The load DeWALT holds is clearly better: at that load, when Stihl was already beginning to choke, the cordless saw worked the same as under its own weight. There was no drop in engine speed. We invite you to watch all the video that we have prepared according to the test results:
The test only shows what it shows - it is in performance that cordless chainsaws successfully compete with chainsaws. This does not mean that wireless models are better in all respects. We do not consider many other issues, at least the same weight, or price, or the ability to work for a long time with maximum load. But in terms of power, the “battery” is already ahead of the petrol competitors, which was confirmed by the experiment.
There are areas of activity where the success of wireless technologies is not even predicted. Imagine the expression of a feller at a logging site in the taiga, who was offered to work with a cordless rather than a gasoline saw at 40 degrees of frost. First he will send you to South America, to Peru - there is the city of Nahui. In fact, the name of this small village is pronounced “Nyaui”, but in Russia they somehow got used to a completely different pronunciation. In short, in any case, no matter how it sounds, the lumberjack will send you very far. Then take a chainsaw, fuel supply and go into the woods.
The amount of work done by the battery saw on two batteries with a capacity of 6 and 9 A * h without recharging
But in the domestic segment the picture is reversed. A summer resident, whose socket is usually at hand, and who can afford not to cut from dawn to dusk, but spend some of the time on something else while recharging batteries, wireless tools are great.
They are easier to operate and do not emit unpleasant odors, they do not need to prepare the fuel mixture and monitor the condition of the filters, you do not need to go to the gas station with the canister. And do not forget that the chainsaw is much more noisy than the rechargeable. In general, where there is an opportunity to work without haste, the “accumulator” has solid advantages.
We do not encourage you to make a specific choice in favor of a chain saw, we just showed you both types of tools in action. Obviously one thing - the times when the usual hacksaw or old-time hand saw was used for different works in the garden area, long gone, and they were replaced by modern technology, the capabilities of which should be used to its fullest.
The test was conducted by Lyubov Balabolina and Alexey Mesnyankin.
