Yes, we do “farm work” with ours. Can they plow or disk in a heavy, wet clay soil field all day? Probably not. But that wasn’t my intention when I determined to teach ours to drive in work harness.
The farm implements the ponies pull are the ones sized for ATV equipment and small tractors or for small horses. We are even working on some customized equipment.
I have had single ponies pull an arena drag, a drag that carries the manure tubs, a chain link drag, trees/logs, a disk.
Besides using them for training, a tire can be used to drag and even out pastures.
With pairs – we have “logged”, moved round bales of hay, pulled a spring tooth harrow with a crumbler attachment, a chain link drag, a small garden disk and a farming disk meant to be pulled by a draft horse or two. We have a stalk cutter that can be set up for a 3 or 4 abreast hitch but have not yet done that (it was pulled for antique equipment display by a pair, but too heavy for field use that way).
Here are some shots of Vicki’s ponies working on Pampered Pets Pharm. Kreature, the silver buckskin, is Bell’s son and went to Vicki in 2011. Eclipse, the black, is related to Kreature, Kechi and KoKo.
