John Deere has partnered with Japanese manufacturer Yanmar on quite a few garden tractor and utility tractor engines. Yanmar also produced some complete tractors carrying the John Deere badge and colours, including the 955, produced from 1989 until 1998.

The 955 hydraulic system delivers 434kg. of lift capacity to the standard Category 1 three-point hitch. Forward hydraulics for the optional loader are controlled by a joystick. The hydraulic pump delivers 1134kg. per square inch of pressure at a flow of 7.2 gallons per minute.
