I'm guessing you're doing straight timothy. Without any conditioner, tine or roller, how long does it take to make hay with your Vermeers? Growing up - aka a long, long time ago in a galaxy far, far away, we ran a New Idea Cutditioner for a timothy/alfalfa mix in western NY. For those who may not know, a Cutditioner was kind of a flail mower with wide (6"?) blades. The theory was that after cutting, the hay went up & over where the butt end of the stems would make contact with the metal shroud, causing them to split thereby speeding up dry down. We could never make hay any faster than 3 days. Dad tried once to do it in 2; damn near burned the barn down. Always wondered if a crimping roller would have made 2 days possible.
