    I am a home owner, looking toward purchasing a trimmer. I have heard that Honda 4 stroke trimmers produce low noise compared to a 2 stroke. Are there any other trimmers including 4 stroke and 4 mix trimmers that are just as quiet or better?

    Sheep are extemely quiet, and are extremely "green" too.

    This 2-cycle-trimmer-noise topic seems to be reoccurring lately, and it baffles me.:confused: A Homelite I once had was indeed noisy and it smoked badly. But the 2-cycle Stihl I bought last year has neither defect, and I suspect the Redmax and Shindaiwa are similar. I don't run my trimmer at full speed, and at the speed I do, it's not really noisy. Even if I do squeeze the trigger to max RPM, it doesn't sound too loud. It doesn't produce a lot of smoke either. I think you would be doing yourself a favor if you demo a few trimmers before you buy rather than rely on someone else's sensitivity to noise. You may find, as I did, that the new 2-cycles aren't that bad.

    2-cycle trimmers are designed to be run full-bore or nothing. Doing anything else builds up carbon in the muffler screen. (i.e., pulsing the throttle)

    Some are louder than others.
    Demo some at local dealers, and demo the 4-stroke units also.
    I used to sell Husqvarna, and they had 2 4-stroke models; one straight shaft and one split-boom (attachment-style trimmer). The attachments from one Husky model fit all the others that took attachments. (edger, short- and long-pole polesaw, tiller, short- and long-pole hedge trimmer, and sweeper attachments).

    Yeah, I've heard that story, but I don't believe it and have not yet experienced it to be true. On the other hand, I do believe a 2-cycle engine can be run at full bore without harming it. And I do that for my chain saws, blowers and hedge trimmer. But not for my string trimmer, because I haven't seen much need to. Even a weak, battery-powered string trimmer can hack weeds. In younger days I rode motorcycles with 2-cycle engines, and I certainly couldn't operate those at full bore 100 percent of the time. Well, I guess I've seen kids on TV doing that when in competition, but I suspect that most of the 2-cycle motorcycles in use today don't really run at full bore all the time.

    The 4 Mix is a great 4 cycle unit that is pretty quiet and I think you would enjoy the little amount of smoke produced by them. I love the 4 mix and after using them I would never buy a small displacement 2 stroke again unless it was in a model plane. The 4 strokes just have more torque, they are quieter smoke less and better fuel economy. Now with the 4 strokes you do not need full throttle all of the time, though they are designed to be used that way. With my KM130 I run it at about 1/2 throttle most of the time, when I hit the tough stuff I open her up (Plenty of reserve power).
