Thanks for your input. That Husqvarna model is a popular one and has 1868 reviews just on Lowes alone. 72% of them recommend it which today is a high number. Here is the refined product review summary: The mower has a mixed performance, with some users reporting it is powerful, maneuverable, and cuts grass effectively, especially on flat terrain. The hydrostatic transmission and reverse mowing are convenient features. However, many users have experienced issues like excessive vibration, problems with the seat and deck, electrical/starting problems, and premature failure of components. The overall quality and reliability of the product seem questionable based on the mixed feedback.
There are common problems in all these mowers that are obvious when you read enough of the reviews. If one is able to deal with these issues as they inevitably arise, and is able to do the work themselves, (which to me is absolutely necessary to avoid adding insult to injury dealing with repair shops) then you can have a machine that will serve your needs. As long as you enter into the relationship knowing this in advance, you should be OK because you'll know what to expect and how to handle it.
I have a couple of questions for you if you would be so kind. Was the Kohler engine the Courage model? Have you experienced any of the issues mentioned above in the product review summary?
