I'm sorry but, yeah, your asking too much for any mower. It looks like your trying to cut thick, healthy grass, too short form the start. Not that the grass is too tall, but you have a nice lawn(thick/green). Looks very wet, at the bottom. The blades of grass look dry at thier tips but, the ground is still wet(look at your wheels). You need to cut your lawn in steps for now and then cut more often during the week and find that happy medium height for your lawn and equipment. Maybe Im wrong but, are your only cutting once per week? I cut mine twice a week and only once in a while, 3X
Our new young neighbors(young couple) just bought a new Craftsman Lawn Mower with everything(elec start, bagger/mulcher, self prop, 6 point something horse Briggs, like a million dollars). Kept stalling out. She called me over to take a look. They were trying to cut too much grass at one time. Not so much that the grass was tall, but the grass was thick and healthy, like yours Chris B. Then I mentioned to them that they might want to cut the lawn 2X per week rather than once/week, week 1/2. That's when I blew my chance for a cold beer!
