First thing.... People who try out or use Stihl 4 stroke blowers, why can't they understand that these blowers are NOT going to sound the same as a typical 2 stroke model from Redmax, Echo, or even the older Stihls??? I keep reading posts where people who have used these blowers get the idea that the blowers aren't revving fast enough, or sound slow, etc.... Folks, these blowers fire every OTHER revolution! Two strokes fire EVERY revolution. Because of this, a four stroke SHOULD sound slower than the two stroke, but in fact the crankshaft is turning at nearly the same speed. The fan in the blower is bolted right to the crankshaft, so no matter how fast it sounds like it is revving.... all that matters is how fast that fan is turning. The four strokes with half as many power pulses, are better on gas and less noise at the same RPM's and this is where most of the benifits to four strokes comes from. I just can't understand how some people can try these units out and come away with a bias against them due to the fact that they don't sound as "strong" or sound like there "Revving fast enough" Second gripe.... What is everyones hang up with horsepower on their mowers? I read comments posted here such as a 36inch walkbehind may not have enough power to mow and pull a velkie.... or just reading the endless comments that you need 27-30+ horsepower on ZTR's with 52 inch decks, etc... etc.... I have never had a engine on a mower that gave me the impression it was not enough power. Sure in tall wet grass, that hasn't been mowed in two months I have had the engine to slow down and bog, but how often do we cut in those conditions? I have never had a engine bog down a noticeable amount going up a hill, or pulling a velkie, etc.... My first mowers were a 36 and 48 inch walkbehinds, the 36 incher had a 12.5 horse Kawasaki and it never had a problem with mowing and pulling my 200 lbs around yards on a velkie!!! The 48 incher had a 14 horse Kawasaki, again no problems. My third mower was a 60 inch hydro WB with a velkie and it had a 18 horse vanguard, again.... no problems whatsoever! My first ZTR was a 61 inch Bobcat and it only had a 20 horse Kohler, again no problems... Each year the mowers seem to come from the manufactors with more and more standard power... My current 36 inch belt drive has a 15 horse Kohler, and my ZTR has 27 horses, more than either needs in my opinion. There is a slew of comments from people that jump in discussions and tell people this mower or that mower needs more power. And you read all the hoopla over these 30+ horse engines people are ordering on their big riders. Makes me wonder how many of these people throwing their two cents into the discussion have used the mowers that were popular 10-15 years ago, when Riders only had 18-20 horsepower and that was more than enough... Anyway, just a gripe, nothing special!
