Earthquake Chainsaw

Does anyone know who makes the Earthquake Chainsaws that they recently started selling at Tractor Supply? They kinda look like Husky chainsaws, whick they also sell at TSC.

I believe they are a product of China.

Made in china garbage.

I have an Earthquake rototiller. It was CHEAP and it shows. A wild thing would be better money spent. For example, my tiller has a "torch" china brand plug that can't be crossed to any known quality plug. Its just cheap all teh way in every way

I have an Earthquake post hole auger. Tecumseh engine. Works ok. That's as ringing of an endorsement as I'll give.

**Zombiechopper** · 07-25-2010, 08:22 PM

mine is a "viper" brand engine.

never heard of it? nobody has....

Junk. All of it is junk.

kill switch works every third time

the real bummer about the "Torch" plug is they wrote BM6A on it. NGK makes a BM6A so that should be easy right? Well, they are two different lengths.

I need to go match it up to something and take a wild guess at a heat range. 43cc 2 stroke. Does not rev real high.

BM6A works fine as a replacement. Have done that many times. The Torch is junk.

my brother has an auger that we have used to place literally thousands of pine trees with nary a hitch. the only problem is that recently the recoil does not rewind all of the way. probably a spring replacement would get it back to 100%, but it starts everytime and the cord only hangs a few inches. not that any of this reflects on the quality of the chainsaw. the auger was bought in '94 and has the tecumseh engine.

Your Viper-engined Earthquake saw is made/imported by Ardisam, inc. They are available in a couple of sizes, and these little engines are also being installed in a few other products.

They amount to a low-tech string-trimmer engine. I don't know this for a fact, but I believe that some of the little pocket-rocket replacement engines are the same. Maybe good news if you're in that market: when the Ardisma saws don't sell, a liquidator like Harbor freight or Cummins will blow them out at $40, and buyers can take them apart and get another few miles out their pit bikes.

The price (IIRC, about $160) seems attractive, but like all things, you get what you pay for. I will accept that there is a market...the folks that buy one, use it a few times then let it gather dust before unceremoniously dropping it in the trash can...but I doubt there are many of those buyers here.

Agreed, it works well enough and usually starts without much protest. Power is decent for one man operation, but with 2 guys I wish it had more oomph.

I bought the 38cc earthquake saw. It's cold natured but when it warms up it runs and cuts like a champ. I throws big wood shavings. I have only had it for a week but so far I like it but it's no stihl or husky It doesn't have the power like they do. I have a husqvarna 235 e-series that is only 34cc and it has a lot more power than the earthquake. I got my eqrthquake on sale for $100 at sears.

Welcome! Several of us have them as well. Mine is ported and the muffler is opened up and runs very well. Here is a thread you may find interesting - there is some actual info in there along with all the BS! dissecting an earthquake chainsaw

The saw is a Zenoah/RedMax G3800 design made in China, but the exhaust port has been made smaller and the muffler is a catalytic converter - I assume to meet emissions requirements. With those things corrected it runs very well. The plastic parts have a bit of flashing and the castings are not a nice as the ones made by Zenoah, but you can clean some of that up easily if you wish.
