I am selling these units because I bought a stronger one and no longer need these, also after an Ebay fiasco I am taking into consideration I believe the price has been adjusted to what I find should be fair, however for this to work the units have to be picked up locally. Before I list the units I will say I don't haggle. The price listed is what the buyer pays if they agree to buy it, I will and do refuse offers, once again the price is firm. The Br-420 is a 2002 model and was used for 3-4 seasons, it has a solid amount of wear and tear to it, this unit starts easy and runs good, the condition is best described as Fair and some repair would be required to make it run like new. The tubes, the shroud, the fan, the engine, the tank and all the fuel and air supply and output lines are in decent shape, the unit does not leak air or fuel and can be ran 'as is' which is what I did until I bought a newer one. The known issues are with the controls, specifically the On/Off switch stays On and so the machine has to be choked off, also the cruise control sticks, the trigger mechanism is in good working shape. This blower likely still meets the rated specifications of 500 cfm's at 175 mph. $120 The Br-550 is a 2005 model and was used one season, it did clean up a lot of leaves in this time and has probably 50-100 hours of use on it. The only known issue with this unit is the anti-static stator wire inside the tube has come loose, this is a common problem and does not affect the operation of the machine, everything else is in good working order and I would describe the overall condition as good. This blower more than likely meets the rated specifications of 530 cfm's at 199 mph. $260 Contact me via PM if interested, local pickup only thou I can meet someone or deliver it if within 25 miles.
