Seeking Rugged Single-Horse Haflinger sized farm equipment

Looking for decent, well put together (not needing repairs I won’t be able to do) equipment for a single, very drafty Haflinger gelding to pull. A wagon or wagonette, for sure, would be helpful in hauling multiple 5-gallon water buckets w/lids, grain, barn dri and square bales of hay out to satellite barns on a 120 acre animal sanctuary specializing in alpacas. Could use a forecart and a snow plow, but the wagon/wagonette is the priority. Would like to know sled runners can replace wheels in winter, as we have a lot of ice and some snow each winter on gently rolling terrain in southern part of NY near PA border, south of Corning. Might not need sleigh runners (if that’s what they’re called?) if we can get a single-horse snow plow to clear the trails periodically. Thanks for reading this…Hope someone has what we’re looking for. 607-525-6656
