Does anyone have any experience using a TR3 rake by HydroSeed Innovations of Osceola, IN? Originally designed by and for landscapers it apparently works well as a horse arena groomer for a variety of materials and conditions, which would be my primary use. Replaces several implements, simple to operate (3Pt hitch mounted), etc., etc. I currently have a Ford 8N which may be too weak to pull the size I'm interested in which is 6.5 feet wide and weighs 900 lbs. (Which means a larger tractor but that's another post.) They are spendy but seem real versatile and very well engineered. Their website is <A target="_blank" HREF=http://www.tr3rake.com/>http://www.tr3rake.com/</A>. Thanks for any input.
