    Are these trimmers considered commercial grade? I am considering one as my next trimmer, and I like the ability to change the oil and using 100% gas with no mix, and Im guessing they have an oil filter of some kind, but it would have to be really small? I am assuming if taken care of well, these could last a very long time, and probably have lots of low end torque? but how is the high end on these, if anyone has one? I would get the biggest one they offer of course. what is the biggest engine/model they offer in this true 4 stroke? Are there any cons to them? Thanks

    No, you better go talk to your dealer, it's a 4-cycle engine that runs on mix fuel,
    also it isn't a torque-based application, it's horsepower based, and yes they have a lot of power.

    Also to my understanding Stihl's 4-cyclers are all commercial grade.

    I have the HHT31SUNBA 31cc with bike handle. It is powerful, very very quiet, Always one pull start. Very smooth, when I first got my Shindaiwa M242, I actually thought there is a problem with the Shindy because it vibrate so bad. It is heavy though.

    It does not have an oil filter. I have the smaller GX25 engine on Mantis also. Both don't have oil filter and I have the parts diagram of the biggest GX35 engine, no oil filter either.

    If you want to get a lighter one, Husqvarna 324L use the GX25 engine and the trimmer is lighter than Honda and I believe Husky is solid shaft vs Honda cable shaft. Also Honda don't have any attachment option where you'll find more option with the Husky. But if you want to big HHT35S, then that's the only one. It is very reasonable priced also. I saw the HHT35S for $359 a lot of places before. $359 for a big 35cc brush cutter is very very cheap. This is as powerful as other big trimmer that cost more. And with Honda reputation. these engines are being used on other commercial equipments other than lawn stuff. People even hot rod them to use in RC model planes.

    My 31cc go through waist high weeds like butter, no effort at all. It uses .105 lines but I like it with .095.

    One thing be aware, they can run in all position but they cannot be store in all position. The cylinder either has to be pointing up or the trimmer has to be hung vertical. Putting side way or up side down for a day or two will result in oil sipping into the combussion chamber and make it harder to start, smoking for a minute after starting. Extreme case people had to take the plug off and drain oil out of the cylinder before starting. This is normal for any 4 cycle engine with separate oil. It does not hurt the engine. Some people complain about oil coming out of the air filter or exhaust, it is due to the same reason.

    And yes, I believe if you change oil more often and use synthetic, you can make the engine last longer than the regular 2 cycle. Because you are in control of the oil, not like the 2 cycle, you cannot put more oil to give better lubrication.

    I think you're talking about Stihl 4-Mix trimmers ... you're in the wrong thread. :D

    I wouldn't buy a trimmer or any other handheld with and oil sump for any reason other than the fact you shouldn't run them upside down.

    Just so you know, a Stihl 4 mix is a true 4 stroke. Operates exactly the same as the engine on your mower or in your truck, the only difference is Stihl has figured out how to lubricate the engine without the use of an oil sump using mixed fuel. This keeps the weight to a minimum by eliminating oil in a tank. It also can be stored or operated in any position including upside down.

    No doubt Honda makes good stuff, but a trimmer with an oil reservoir is not a good idea IMHO.

    Every time I stand up straight while holding a trimmer at the dealer, the spool ends up being about 10 inches off the floor. If I want the spool to touch the floor, I gotta lean forward. When I lean forward, I then have to bend my neck back, putting a strain on my neck muscle. I'm thinking I might have to end up getting that extra long Tanaka.

    Honda is designed to run in all position, no problem with that at all.

    4Mix type of technology has been around since WWII, it is not new.

    Yeah, he's really in the wrong thread.

    I have the honda... heavy but powerful. Starts good, quiet, good power.

    Seems fairly well balanced overall.

    Ive been using a 4 stroke trimmer for several years. I use it in all positions, treat it rough and only adjust the valves very in-frequently.

    It seems to me that most people who say you cant use a 4 stoke in different positions or that there's this problem or that problem probably never owned one or maybe had a lemon.

    My experience has been completely positive.

    I had the Honda and an old stihl FS 90. The honda now hangs in my garage and I have switched entirely to the new stihl 4 mix FS 90s. If you do buy the honda you really need to be careful how you store it and Id recommend purchasing extra insulators for the carburetor. They are very brittle and get cracks in them very easily, and then it wont run. Plenty of power, a little on the heavy side but it was a good machine... just not very durable.
