Not bad idea, perhaps perfect for my tractor too. My lawn tractor which I now called it suicide tractor. After all BS with safety that was causing too many problems. I took all of safety features out. BAM! it works perfectly. I no longer buy battery for these lawn tractor. They are way too expensive. I used portable battery powered jump start. Works every time, and it works with vehicles too, and it is cheaper too. Lawn tractor batteries now cost 40 dollars, and if your lucky enough that it will last longer than 2 years. My last battery jump start unit last me almost 10 years, for price of 100 dollars, can't beat that.
Every time when I start my tractor, I have to make sure everything is set up properly, like in neutral, blades are off, etc. I don't see reason for these safety because my yard is pretty much flat. I hate turning off blades when drive in reverse. Now I can without turning off blades.
I hate mowing lawn, and the reason for lawn tractor is to avoid grass allergic reaction. If I walk behind, I can't mow no more than 10 minutes and will take me two days to mow my lawn, with tractor, less than 20 minutes and the grass dust stays behind me not in front of me.
