How do I get my Westwood Gazelle to cut evenly?

The mower cuts unevenly in that the grass is longer in the middle of the cut. How can this be rectified please? It has a single blade.

make sure that tyre pressures are equal around .... blades make sure that sharp ... check deck bearings might be worn..(also loose blade/s)

To cut evenly in the forward plane, adjust the tension in the rear cables to get the deck horizantal. To cut the same height side to side adjust the cradle height at the rear end.

sharpen the two blades with a file.
