You’ll probably not going to like me after reading my answer, but I must speak the truth. With the mower you have there is just about nothing you can do to solve your problem. Only possible solution is to raise the cutting height as high as possible and mow more often. Your mower is the problem. It is one of the cheapest units available, with the cheapest engine Briggs makes. That combination will never go through a thick lawn unless you only remove 1/2” at a time. What you need is a good quality unit with a larger engine. By that I’m talking about Toro, Honda, Ariens, etc costing $500 on up. I personally don’t feel those units built by Husqvarna and MTD will do the job you want, no matter what the salesmen say. Sorry, but I’ve seen this problem many times and don’t have a better solution.
