I have a lawn mower that will soon be going to the junkyard. I was wondering if it's magnito could be used to generate electricity by wind power (wind turbine). I would use it to charge a deep cell battery.

It puts out about 20,000 volts, you sure you want to charge a battery with it?
I did read somethng to that affect. Something to do with a primary winding being encase by a secondary winding of lotsa fine wire. What if I eliminated the secondary wire winding(s) ?
I've made a set of blades which I then mounted on a hub. I then put the hub on a horizontal shaft (no bearings) and attached the shaft to a tall metal pole mounted to my grapevine support. We've had some winds lately and you should've seen this thing whipping around. Eventually one of the blades came loose and flew off about 60 feet. And all I could think about was all the elec juice it could have produced if I had a generator and bearings. Of course the above was done to test my blade design. I am satisfied with the blade design but can't seem to come up with a suitable generator. With all the junk we Americans toss into landfills it seems I should be able to come up with something for little of nothing. And since my lawn mower has seized and will eventually end up in said landfill I thought I might salvage something from it..

Good thoughts but forget the maggy, it wont be of any real use. You need old car generators or more better a Fisher & Paykel washing machine motor. Google "Fisher& Paykel wind generator" for more info.
That's a lot of work for nothing. You're better off grabbing a 12 VDC wiper or window lift motor from a junkyard and using it to generate your DC power via the wind turbine.
