This question is something I have been pondering over. Personally, I have never owned drafts although I have owned several other horses including riding horses and buggy horses and have hitched and driven my neighbors team of Percherons numerous times. At the present I own no horses as I and my family are stationed in Togo, West Africa as missionaries in a little rural bush village. My mother sent a package to us in the mail and included a few Rural Heritage magazines as well as a Father's Day gift of Uncle Joe's books "America's Rural Yesterday" volume 1 & 2. Very interesting! Also extremely interesting to show to these African farmers how our ancestors farmed! In our region, animals are not used. All soil turning, hoeing, planting, and harvesting is done strictly by hand. (The farming methods used here could be another subject all on its own.) Anyways, as I have been reading and perusing the magazines and books, I see that almost all draft horses have blinders, but not all. In J. C. Allen's photos, you will find in the same hitch where some horses have blinders and some don't. In the recent Aug./Sept. issue of R.H. on page 33, a four horse hitch is completely blinder-less. Mr. Leo de Visser (page 34) also uses no blinders. Is this personal preference of the teamster? A sign of a well trained horse? An accident waiting to happen? Some questions I've had.
