As much as I love my JD tractors, I don't get hung up on the JD brand when it comes to attachments especially one as simple as a rototiller. Good chance someone in this world is contracted to build them for JD.
That 673 Deere tiller is made by Machio as I understand it. I till lots of small pastures with mine and it has held up very well with heavy use.
I have several different brands of attachments and all seem to work well enough. I just seem to notice that Deere seems to be singled out to "talk down" more than other brands on this forum. It is no wonder that a large percentage of Deere equipment owners have left this forum for GTT. I try to keep an open mind and will say without reservation that there are a lot of great brands to choose from today. But it seems EVERY TIME a poster inquires about a Deere tractor or implement someone has to come in and talk it down. I don't see this happening with all the other brands.
I sincerely apologize if my comment offended you. On the contrary I was simply trying to convey the high quality of JD's attachments as a standard by which all others are compared. I'll be the first to agree that the service and parts availability provided by your local JD dealer can be priceless. I didn't mean to undermine anyone's desire to buy JD attachments, simply that they have good options.....sometimes. Please accept my apology.
