Hey all I hope there is a john deere guy here somewhere that can help. I just got my first sled and the kids and me love it. it's a john deere trailfire 340 from 1980. The track has a rip but it's cleated so we are still running it. I have found a guy how said that he has a spitfire track all so a 1980. will they just change in and out or i there something I need to do to get it to fit???? any help is great cause I have no idea. I have a buddy that has a 440 citition says he can help me change it but we can't find any info as to track size or length. So I found this place and was hoping someone here would know thanks for your time and happy riding!! oh ya only paid 200 for the sled. good deal?? or no ??
