If it was my tractor, i'd get a 5' med duty brush hog. I'd also make sure it has the slip clutch in the drive line. Personally, i like the Woods Brush Bulls. Keep in mind, just because it's a 5' hog, doesn't mean in really tough conditions that you have to take a full 5' cut!! You said rotavator, so i'm assumeing you are talking Howard. (only Howard has rotavators) In tough field conditions 60" will be too much for 29 hp. For gardens, you probably can get away with it, but i wouldn't buy one that big if it was my tractor. I have (3) Howards, and i don't find i need 10hp per inch, but "if" you get the multi speed gear box, use a higher gear, and close the back door, and go full depth, and have tough conditions the 10hp per inch will be close. Thing is, in all the years i've been doing custom rotavateing, i've NEVER had to do all of the above! I don't find that hard clay takes near the hp that wet heavy soil takes!! Clay just gets ground up and is left behind, wet soil balls up and goes around and around pushing a berm ahead of the rotor blades. NOW, that takes power!!! I've made most of my $$$ rotavateing with an 45hp Agco tractor useing what today would be, a HR20 72" with slectatilth gear box. Clay would be hard on the machine, but really don't take a lot of extra hp. I get that all the time, someone saying i can't rotavate there clay, cause they have a heck of a time plowing it!!! It just doesn't work that way. When i leave they are happy campers.. Think about getting something like a 50" for your tractor, and at least an HR8, a HR10 would be better if you plan to work it hard. Robert
