Henry Ford's historical 50th year anniversary 1953 Ford Jubilee (NAA series). 32 hrp, 4-speed, 4 cylinders gas engine. Originally 6 volt positive ground, has now been converted to 12 volt negative ground. These tractors have an engine driven hydraulic pump as compared to the "N" series which relied on PTO driven pump (a significant advantage). This tractor has included the optional feature using a seperate pump providing hydraulic pressure which is used to disengage the transmission from the rear axel (extremely appreciated when using a 3 pt post hole auger). This a sweet tractor and fun to drive. I like the extra gearing providing a low-speed range which the "N" series lacks. The extra power allows for using 5' brush hog type mowers and larger field equipment. I am thinking it is in good to very good condition.
