Field Testing: Putting the Greenworks 80V to the Test

The real test of any chainsaw is how it performs in the field. I subjected the Greenworks 80V to a variety of tasks, from limbing small branches to felling medium-sized trees. Here’s what I found:

Limbing and Light Cutting:

For limbing and cutting branches up to 8 inches in diameter, the Greenworks 80V performed admirably. The lightweight design made it easy to maneuver, and the instant start was a huge time-saver compared to cranking a gas saw. The chain speed was sufficient for quick, clean cuts, and the battery life was impressive.

Wood Types Tested: Pine, Maple, Oak (small branches).
Performance: Excellent for limbing and small-diameter cuts.
Battery Life (Limbing): Approximately 45 minutes of continuous use.

Felling Medium-Sized Trees:

I then moved on to felling trees in the 12-16 inch diameter range. Here, the Greenworks 80V started to show its limitations. While it was capable of felling these trees, it required more patience and careful planning. The cutting speed was noticeably slower than my gas saw, and I had to be mindful of the battery level.

Wood Types Tested: Pine, Oak (12-16 inch diameter).
Performance: Adequate for felling, but slower than a gas saw.
Battery Life (Felling): Approximately 30 minutes of continuous use.

Bucking Firewood:

Next, I used the Greenworks 80V to buck rounds of firewood. This task fell somewhere in between limbing and felling in terms of difficulty. The chainsaw handled it well, but again, the cutting speed was a factor. I found that using a sharp chain and applying consistent pressure were crucial for efficient bucking.

Wood Types Tested: Oak, Maple, Ash (firewood rounds).
Performance: Good for bucking, but requires a sharp chain.
Tip: Use a sawbuck to stabilize logs for safer bucking.

Original Research: Comparing Cutting Speeds

To quantify the difference in cutting speed between the Greenworks 80V and my Stihl MS 462 gas saw, I conducted a simple experiment. I cut through a 12-inch diameter oak log with each saw and measured the time it took.

Methodology: Cut through 12-inch oak log and measured time.
Greenworks 80V Average Time: 22 seconds.
Stihl MS 462 Average Time: 14 seconds.
Conclusion: The gas saw was approximately 57% faster.
