loss of power

My 154 does not mow grass very well at all. If it is even just a little bit thick it will bog down and i have to stop to let it catch up. What can i do to help this?

What gear are you mowing in and how long is the grass.

Now comes the questions?

When was the last complete engine tune up, including compression tests?

Type of mower? Blades sharp? Mower in top notch condition? Mower set up correctly?

Type of grass and how tall?
