Hi all, as mentioned in a previous post...I bought an LP1160 land plane with my 2025r, and couldn't be happier. I'm using it a lot more than I though...each time you make a pass it just reclaims more gravel and makes things that much smoother. Question though, in the photos online they have a black tube about 16" long attached to one of the 45degree uprights. I dont have one on mine, amd I missing a part or something? It seems like I have everything I need...and I can't think of anything I dont. What is that tube for, and do I need to call JD or something?
