Firstly look underneath.
This mower has only 1 blade so a bent blade will not cause an uneven cut but might make swirls in your grass if you are mowing quickly.
On the let side there is a sliding plate which moves back & foreword which moves that side up & down.
So you turn the blade till it is directly across the mower, maesuer the heigh at the rich side then adjust the left to match ..
This might cause a light sifference to the right so you might need to do it to or three times.
Once done you then turn the blade front back & adjust the front about 1/2 lower than the back.
There is a small platte with an arched slot and two bolts, loosen both just enough to rotate the plate.
Before you start adjust the tyre pressures.
