Sure reads like the lawn conditions are such that the blades will require more regular sharpening to provide best performance.
This is a reasonable DIY, just use tools designed for sharpening blades, and you'll likely get better results by removing the blades from the mower for the procedure. Be absolutely sure to use gloves when working around the sharp blades, pay attention to the order and orientation of all parts (bolts, washers, blades, ) when installing, and use a Torque Wrench to properly tighten the blade bolts. All the steps are in your owner's manual [digital copies can be downloaded free from
