The Land Pride BS10 & BS20 Series Bale Spears can be attached to machines fitted with a Skid Steer adapter mounting plate, while the BSE10 and BSE20 Series Bale Spears can be attached to machines fitted with a Euro style adapter mounting plate. Bales can be pushed onto side dump trailers with single and double spear units. Single spear units take less force to push the spear into the bale and bales of all sizes won't shift positions as easily while pushing the spear into the bale. Double spear units have twice the lifting capacity. The two spears spaced apart also miss the soft inner core of a bale and probe the harder outer area allowing the spears to lift a heavier bale.
