Back from town. My goal was to compare all the trimmer brands with the Stihl 40.2cc engine, 13.9 lbs. total dry weight, and bicycle handle set-up of the FS 250.
My 1st stop was a Shindaiwa dealer. Their most popular commercial trimmer/brushcutter was a 23cc unit. Their largest unit on hand was a 28.9cc and it was heavy 15.7lbs. Primer Bulb was on the bottom of the unit, well out of harms way. The On-Off Switch and Trigger Safety assy is so-so. Good solid units.
The Echo dealer didn't have anything larger than the SRM-266U, a 25.4cc unit. The On-Off and trigger features were very similar to the Shindaiwa's, but a little sloppy in their actions. Primer Bulb was on the side of the engine.
Both Shindaiwa, and Echo's cables are exposed. A design feature that I noticed right off, as I'm always backing into brush, or crawling through barbwire fences with my trimmer. Although I've never got it hung, it keeps me cautious. The compatible SRM-410U 42.7cc, at 18.3 lbs. Trimmer lists for $579.
Last stop Stihl. She has several FS 250's ready to go. The On-Off and trigger features were similar in appearance as the other two, but very precise and smooth functions. The top of the engine, including the cable connections are covered. I like that. The Primer Bulb is located on the forward side of the engine. A feature that surprised me, but more convenient in after thought. Wasn't very fond of the weight and balance until the attendant brought out the harness and fitted it on me. Man that is a life saver. No weight to fight, just steer it. We discussed the two types of harnesses, and after I tried the standard one that comes with the unit, I will have no problems with it just as it is.
At the end of the day. They all were good looking units, some a little heavy, but with the bicycle handles and harness, they're great. For my personal use and experience on the ranch for yard, pasture fence, corrals, out buildings, and woodlot, I'm going with the hoss FS 250.
BTW SawTroll: They didn't have the new FS 240.
