We needed a second blower and having had excellent service out of our first SR6400L we bought another. Incredible power and though a little heavy, they are very good at their job. We have a couple of acres, all of it wooded. We blow the sides of the home and the front. More leaves than you can imagine. Yet yesterday, the DW and I got the job done in about 3 hours. Amazing. I only have one small suggestion for Schroder.... The thumb screws that hold the top of the air cleaner on are the weak point. They work loose, and if you tighten them up snuggly, you end up stripping the threads. I finally found a long machine screw with a rubber spacer and a nut, and fixed the older machine, but already the two thumb screws on the new one are coming loose. Don't let such a minor item dim the shine on a terrific piece of engineering that this model SR-6400L is. Put out a fix for this. ;-) We love these blowers, and the new one is two pounds lighter, meaning the wife uses it without a single complaint. Very nice piece of equipment........fix the thumb screws.

**Review Update** Been over a year now. Blower has bwen a real work horse. Love everything about it. Especially the well padded harness. A couple of improvements would be appreciated. 1.. mold into the frame a foot brace to make starting easier. 2.. add a cruise control to the blower speed control. Basically be able to loc the blower at a preset speed.. would help with trigger fatigue. ** Blower arrived the other day. Well packed and additional protective cardboard lining. Very easy to assemble. Only took a few minutes and a philly's screwdriver. FIRST IMPRESSIONS: Unit is well made and well designed. One thing I did not see in any of the reviews was that the unit comes with 2 blower tips. A faired tip and a round tip. Wondered, because I saw both pictured but not described. The next thing I noticed was unlike other backpack blowers I have had, this one had threaded screws that hold the sections from coming loose. They still use the twist lock sections but with a screw, not into plastic but metal on metal. The unit is powerful. Much more powerful than my old backpack blower or my hand-held blower. With the flared tip, it can move a lots of dry leafs, wet leafs, leaf mold, gravel, blows small sticks and dead wood easily and clears a wide path. For the money it's a great blower and a good value. Be aware that these ship from BC Canada and had to go through customs which added a day or two. Now for the things you should also know. I assume this motor does not have compression release. Takes some strength and a good stable area to start. I hold the backpack at the top and brace my boot on the lower frame. Takes a couple of pulls normally. Not nearly as easy as other 2 strokes I have had. My 2 cycle snowblower took less effort. Vibration: Evidently this blower also has no Vibration dampening. Not too bad and you sort of get used to it after a while. NO cruise control. Now this may seem like no big deal BUT… Engine speed is controlled by the trigger on the hand grip. No way to keep the motor at full throttle without a finger on the trigger. When you spend hours blowing leafs it's nice to vary hand positions. Trust me, you will be looking for a rubber band or two if you have a large area to clear. I would say, a tank full of mixed gas will get you about 2 hours of run time.. not bad for the power this generates. Overall, I am very impressed with the quality and utility of the blower. Hope the manufacturer reads this post. With a few low cost modifications this unit could be world class. Maybe that's what you get with their $700+ model.. don't know. Reading the description the models sounded basically the same.

We have a one acre property that is pretty heavily wooded... I normally blow the leaves into the back woods during late November... I was preparing my Ryobi blower for this year when once again, I could not get it to turn-over... I've had the blower for a few years... Have always used ethanol treatment in the gasoline... I've replaced the carburetor once, and the pull start assembly twice... The engine has always been hard to start, and typically would start to bog down after a short period of operating... This year I was faced with another carburetor replacement and pull start assembly... I had enough... I went on line and decided to purchase the Schroder SR-6400L, based on the reviews... About the same price point as the Ryobi... The blower arrived a day early... It was easy to assemble... It started on the second pull out of the box, and subsequently on the first pull thereafter... The trigger pressure was easy... The pull start a little stiff, but okay once you knew what to expect... The blower runs great, and the blowing capacity makes quick work of getting the leaves where you want them... The gas tank is pretty substantial, but fuel consumption is consistent with the work that this unit delivers... This is a well engineered unit... I wish that I had purchased this blower a long time ago...

It's a pretty good blower and it runs very good.Gas leaked under gas cap for some reason duck tape inside the cap helps for now will try a new washer later. Overall I'm happy with it. It cleans and starts pretty quickly throw out plenty of air with great strength and the harness straps are okay also.

Mine was placed into service 11/12/2025. I’ve used it several times making huge piles of leaves so that I can use my mulcher to shred them for compost. This blower has plenty of power. I've had no problem starting it. The only assembly is with the tube, it took me about 15 minutes and then I was up and running. This machine is advertised as light weight but I would say that depends on the user. For me it feels heavy but manageable. I doubt if my petite wife could use it. Too heavy for her. I do concur with other reviews that it would be nice to have a place where you could anchor your foot while starting. I can get a toe on the frame and then lightly place my other hand on the air filter while pull-starting. A tank of gas will last about an hour of non-stop use which I’m ready to take a break then anyway. Overall, I like it and I’m glad I have it.
