Replying to Backyard jam; snowmobile tow?

I have a couple of small fields near my house that have been begging to be made into a park for the past few years. Only thing is there's only one place to have an actual drop in. BUT, I got a snowmobile this year, and plan on getting a tow rope to get the speed. I was wonderin if anyone out there has experience with using snowmobiles to tow you up to speed for jumps. Is there any way to calculate the speed before hand, or do i just have to be a guinea pig and huck it?
