Thanks sheder - I am 6'3 - 240 and size 13 shoe and have similar concerns on pedals. I am looking at the folding SST or AL pedals they have for min ex's in lieu of the large fixed pedals on these machines - only $30 a piece.
I plan to do other mods too - adding the brace and covers between the wheel motors with a hitch setup, and already bought steel for cutting edge for front blade. Already bought the tilting bucket, Screen bucket and QA for the buckets and looking at maybe getting the bigger 230MM 9" wide tracks - Chris said the tracks are 230x72x41 - can you verify thats the track size (should be a number on the inside of the track).
Mine should be here in the next week +- peer Chris. Thanks again for the detail on fit and finish, and send more pics when you get a chance.
