These mowers were horse-drawn and used to cut or mow hay. Often they featured mechanisms that lifted the cutter bar to clear rocks, stumps, or other obstructions. The Adriance, Platt and Co. (Poughkeepsie, N.Y.) mower was probably built in the mid 1910s. The International Harvester No. 9 mower was introduced in 1939 and was one of Harvester's last horse drawn styles. The John Deere No. 2 was introduced in the late 1910s and featured totally enclosed drive gears running in oil. An additional mower blade lies next to these mowers.
