Ahhhh.. Indeed 'hmearth' ~ ^ I did just notice that you are in Australia though, and likely NOT going to be using your machine in weather as we are discussing above for Snow Removal ** was -20ºC outside here earlier _ quite likely machine will be used in -30ºC [-22ºF] a few times this winter.. Yay, sounds fun indeed, doesn't it..?? Ha!!
However, I would definitely like to know more about the McLaren tracks, and esp models for cold weather Snow/Ice usage though _ and I have NEVER been afraid to pay for 'better parts' if they prove to be that, and actually did send a Quote Request to McLaren about 4 hrs ago _ So I will see what pops up in the future from them, and if there even is a Local Rep (which I am hoping) so that I can see some of their pieces/ get reports from local snow removal users perhaps!!
Thanks 'hmearth' for the info and insight, much appreciated as always, and I am happy to learn and get feedback from folks here as it is the BEST way to learn that I know.. Take care, I shall 'report back' on any and all info that seems useful accordingly!!
