Hi I Just bought a Honda HHT31S bike handle 31cc 4 stroke trimmer. IT IS AMAZING!!!:jawdrop: 1) It is soooooo quiet. For those that live in denser area where noise is a problem. There is 4 cycle and there is 4 cycle. I have a brand new Shindaiwa C4 blower. I start it and put it side by side, you can't even hear the Honda. When you rev it up, the noise from the string head is as loud or even louder than the motor!!! I trim half the yard before I realized I forgot to wear ear protection!!! 2 This is a discontinued model, the new one is HHT35 with bigger engine. I bought this one because I don't like the timing belt of the new one even everybody told me that it is not a problem at all. What can I say, I am stubborn!!! I am lucky enough to find a new old model. The GX31 is a push rod engine. But this one comes only with bike handle, maybe that's the reason it is still sitting there. I was worry about this. I try the trimmer out this morning. It is so much easier to use than the convensional loop handle it is amazing!! I adjust the handle at position that the trimmer head side barely tip forward when holding the bike handle, I don't use the strap/ belt. I just tuck the motor to my right side. It is the carb. side and is not hot. It is so easy to control. This might not be important to pro that are very good in controlling the trimmer. For weekend warriors like me, I can never control the trimmer that well with the normal loop handle. The bike handle together with the motor tuck close to the body give me so much more control than my other one. For all you left-handers.....well.....you will have barbecue ribs!!!!: It is heavy but with the bike handle, it really does not feel heavy at all because it is so much easier to hold than the normal loop handle. Your neighbor will love you for the quietness. I read a lot of posting on different lawn forum, nobody say anything bad about Honda trimmers other than they are heavy. This is really not an issue as stated above and we don't trim that long anyway. It is good for you, take it as weight lifting!!! with the bike handle, it is not even that!! Have a nice day.
