Small Engines (Lawn Mowers, etc.): Weed Eater Mower, insurance deductibles, florida lady

Question
When I push up the lever to lower the blade, it doesn't cut..I did see a belt loose but wonder if this is a simple enough repair a hurricane tired old Florida lady can do, or do I need to have it taken in? It is a Weed Eater Mower and I bought  it from Home Depot about 6 years I don't know the model but it has  a 36"blade cut and I think it is a 9 or 10 h.p.

Really appreciate any help...the insurance deductibles from the hurricanes has eaten up any extra money I had.

Answer
I'm not sure what model you have but the I would follow the cable from the lever to the cutting deck.  You may have to remove some parts to see where the cable goes.  Anyhow you should find an idler pulley attatched to the end of the cable.  When you tighten the cable, the idler pulley should tighten the cutting belt.  There is probably and adjustment on the idler pulley bracket or the cable to tighten the belt; this may help or you may need a new belt like you stated.

Is this a riding mower?
Let me know.
