Abstract: A baler for hay, straw, grass, and similar feed materials is provided. The baler communicates compressed material from a vertically inclined compression passage formed in-between opposing conveyer belts to a central area of a baling chamber for baling. A plunger within the baling chamber can reciprocate in two directions to form bales which are tied and discharged from both ends of the baling chamber.

Abstract: A protective cover assembly is provided. The protective cover assembly includes a flexible cover and an alarm assembly. The flexible cover includes an outer layer of flexible material, an inner layer of flexible material, and at least one layer of tear resistant material positioned between the outer and inner layers. The alarm assembly includes a pair of conductor plates positioned between the outer layer of flexible material and the inner layer of flexible material, a power source, and an alarm system electrically connected to the power source and at least one of the first and second conductor plates such that upon an electrical conducting implement piercing the first conductor plate and contacting the second conductor plate an electrical connection is established between the first conductor plate and the second conductor plate thereby causing the alarm system to emit an alerting signal.

Abstract: A hay baler having two bale chambers arranged end to end in a straight line and a single plunger reciprocating in both chambers. Drive for the plunger may be by cranks and connecting rods on each side of the plunger or by a planetary gear train driving a crankshaft.
