Welcome to Tractorbynet, Baron. You've gotten yourself a fine tractor. As for tillers, I would recommend one wide enough to run with it centered and covering both rear wheel tracks. A distant second choice would be one that can be offset to cover the track on one side. Some people may debate the merits of gear vs. chain drive, slip clutch vs. shear bolt, forward rotating vs. counterrotating, and one brand vs. another. But to the best of my knowledge, I can't recall anyone posting any messages complaining about the brand he/she bought. They all seem to do a good job, and are generally pretty tough, long lasting implements. My own tiller was a Bush Hog, chain drive, and was used a great deal for a lot of heavy duty work for 7 years with no problems. I was very happy with it, and I have a cousin who still has a Bush Hog for his TC29D New Holland. However, if I were buying today, I'd likely shop around and might buy one of the cheaper brands.
