Terrance Heaton rented land from Tom Glowack. Heaton owned two disc harrows that he ceased using and left in disrepair on the property. In 1984, the Farmers Home Administration (FmHA) acquired title to the discs via a security agreement with Heaton. FmHA left the discs on Glowack’s land after the purchase. In the meantime, Glowack permitted his neighbor, William Gray (defendant), to take possession of the discs. Gray hired Jed Maggert (defendant) to repair the discs. Maggert performed $857 worth of repairs on the discs but was not paid by Gray. In December 1984, Martin and Lylia Timmer (plaintiffs) purchased the discs from FmHA for $75. The Timmers did not inspect the discs before the purchase. Both FmHA and the Timmers believed that the discs were in disrepair at the time of the sale. The Timmers brought suit for replevin and conversion to obtain possession of the discs. The trial court found the Timmers to be the owners of the discs but that their ownership was subject to an equitable lien in favor of Maggert. The Timmers appealed.
