3gunr, While that's true I'm sure that you won't find a bolt up ready kit elsewhere. If op wants it to look as stock as possible and as easy to put on, he's going to have to source a TYM kit. $$ yes, but easily assembled and looks are what come with the kit.
Reno123, not sure where you are located but I bought my RK37HC 3rd function kit from Rural King since TYM makes the tractors for RM. The kit came with all hoses, brackets and so forth cut to the correct lengths. The box and all parts have TYM labeling. The part numbers for the kits vary by RK tractor model but if you have a Rural King near by you possibly can contact their tractor folks to see what kit is compatible with your model.
