I purchased a long yearling at Waverly this spring, who had been started and driving about 2 months when we got him. I was concerned about overworking, but his Amish fitter told me he had just done some easy wagon work on the road, as part of a team. In any case, he turned 2 in May. We have been working him with increasing frequency, but I am often concerned about how much is too much at his age. Our big problem is hills, which make even the lightest wagon a hard pull on the uphills. Is this acceptable a couple of times a week? We've also been doing some light scraping, with a snow blade and a little bit of slipscraper....less than 30 minutes each a week with him as part of a team. How do you judge what is enough? I certainly don't want to overdo it.
