Ive looked all over and haven't found any info on someone re powering a bolens 850, my old Wisconsin is wore slap out and i can afford the down time of rebuilding the original motor so im wondering what i can swap it out with to be able to get it back to making money again, i use it for small grading jobs, pushing gravel and leveling it in small areas, along with many of other duties. also trying to be budget conscious about it to. i love the little thing as it gets into small places that a big machine cant. would like to figure somthing out soon as i have a small job that i have to use it for in a week or so. thanks and hope to here something soon.
