I have a chance to buy a year and a half old Lesco 48" Commercialplus mower. It looks like it is in great condition and has the Kawasaki 15hp motor. Is there anything special I should look for on this mower that has a tendancy to wear or break? Is there any particular maintenance pointers you can offer? It has new drive and pulley belts and the blades are in excellent condition. He is going to throw in the mulching kit the grass catcher and deliver it. I can buy this at half the price of a new one and even though it's a little too large for my yard, it's a hard offer to pass on.
