I have run my 214 blade with turfs and no extra weight and it did perfectly fine. I am 5'11" and 190 lbs.
I've plowed 5" of icy snow and added only a pair of 50 lb. cast wheel weights.Most of the time wieghts are needed with a plow when using to clear snow. Since snow typically has ice under it and you need to push large amounts that is where weight is needed the most. It would be good to have ag tires or chains on possibly but you can always just try using it without doing anything else first. That is the cheapest option. If you had the 26 inch ag's with fluid you would be more then covered.
