I'm thinking about buying the JD F-525 with a power flow bagger. Plese give me any information that you may have about the F-525. Is this the unit to go with or are there much better units for the same price? Are there any real disadvantages to buying this unit. Will the 17 horses pull me around fast enough, need to diet 225 pounds! I have a JD L-120, but it is too slow. Thinking this unit may be faster cutting! Any information would be helpful.Thank you in advance.
