Good on you I have dragged mine from the shed down to the garage and back a time or two and had to get it out the basement I bought it from. They are a "bit bulky"
You are not quite done yet. Grab a big file or your air grinder and round off the 4 corners of the lip on the platform, hopefully before you tear your jeans the first time! You have been warned, I wasn't. Make about a 1/2" radius and round it over, hit it with a bit of red paint.
I still haven't gotten around to putting a decent front wheel clamp on it.
