The cost for tracks on a small 30hp tractor would dam near kill you!! I have not put tracks on any thing that small. Have bid out some tractors for park deptments for this fall , but they are going with 65 pto hp and up,What I would try is to chain the tires or if at all possible run duel wheels on the rear of the tractor, and chain the out side tire . And with the duels , if you can go with a narrow set of duels tires, we say the taller & narrower the better .Ok ! One more thing try running the tire backwards , if you don't care to chain them ,that is the tread or lug , this can be done by just flip flopping the tires , right to left , it will pull better And if that won't work I have a older Alpine twin track with high / low & reavers that could pull that drag !!
Just seen this post !!! They have tried them down here and for a small home use type may but need to set up a rear mounted drag , which skid steers are made to push more than pull , if you keep the bucket full of snow yes it would help when it came to pulling .
Mine seats 7 and can easily climb any slope you can show it!
