I weigh about the same, had the same problem. I didn't defeat the switch but I put a piece of rubber air hose tubing over the lever of it so it was pushed down just a little more. I think with the switch on mine it was 1/4 id tubing but may have been bigger.
Not in front of me and nasty cold out to go look and take a picture.
It has worked for me for 3 years now.

What Bill aka
@Chanceywd did is the way to do it. Sometimes they just need a little "shim" of some sort to make them more user-friendly.
At 230#+, I'm a little more stout. My seat switch is embedded in the seat cushion. Things got a little twisted around down there over 10 years.
I cut a piece of cardboard to size and slid it in to be on top of the switch pad. Still works as intended.
Same effect as Bill's 1/4" hose. A little bit of a shim.
Works great.
Bill has a Ford "N" series and I have a Minneapolis Moline ZAU. Neither have any safety mechanisms. They can be dangerous if you don't pay attention. I think we both have enough experience to accommodate that.
For a novice, I'd wouldn't suggest bypassing a safety feature. I had my seat switch bypassed for diagnosis and considered leaving it that way.
Didn't want the next owner to get hurt because I bypassed it.....
