    I just started out about a month and half ago and do 6 accounts a week. My mower has a mulching kit on it. I have 11 hrs on the mower, so when should I change the oil and sharpen the blades? Thanks.

    you may as well go else where for your info because these guys here are pretty much loosers. change the oil when you want too just dont go to long. about 20-25 hours of cut time change the oil, you cant do it to much to often. if the mower is new change it at 10 hours then go 20-25.
    as far as the blades go just watch out where you run the mower and if you dont run over a bunch of crap you can go about 100 hrs.
    good luck

    if thats a new machine, change the oil now. 30 to 40 hrs thereafter.
    I have several sets of blades, so I change them out daily and sharpen in groups of 3 or 4 sets when time allows.

    Like Stumper said, change oil 30 to 40 hrs if it's a new mower. Then I would 50-60 hrs. when it comes to blades and only doing 6 lawns I would say sharpen once a week.:)

    I sharpen my blades every 4 yards or every day, whichever comes last:
    - Once I have cut at LEAST 4 yards, they get sharpened but never do I let it go longer than a full day if I cut more than 4, then I sharpen them.

    Far as oil, I've been running motors for 20-some years and I've learned over time how to determine from the color of the oil whether it needs changing, or not. For everyone else, I recommend going with the manufacturer's recommendations, for myself I run TWO mowers and run them interchangeably so NO mower ever runs with dirty oil (it doesn't turn black, ever... Not even dark brown), I run at least a synthetic blend (mostly synth.blend but sometimes pure synth.) AND I change the oil in my motors once/year but you have to know what you are doing AND *I* am responsible if the motor blows.
