The factory ones from AGCO seem expensive but they are what seem best. They do better job of not cracking and causeing problems. We have over the years tried all sorts of them thinking the factory ones were too expensive but in the long run they are still cheaper as the others do not last. The worst are the steel flex tubes, they appear too last but tend to leak a lot.Other brands like Deere and such sell about the same style factory hose and you may find some there. The hose seems to have a cloth wrap type appearance with a smooth inner core and wire spirals...........vstk
Tom, I used a piece of suction hose(plastic, air seeder type). Thought it may be too hot for that type hose, but it lasted this season with no problems(150 hours)
Thanks, guys. My R60 has flexible steel tubes. I assumed they were original but who knows what you get when you buy a used machine. With the cost of a new engine being what it is, its better to give it the best possible care. The flex tubes are history.
