I have not been able to find out the year my kubota was built. The serial # is 58914 and the engine model is DH 1101-A I've looked at a lot of sites but have had no luck. It had 909 hours on it when I purchased it 9 years ago. Now it has 1400 hours. It's been a fantastic tractor. It has four turf tires and has a wide stance. It has a front dozer blade hydraulically controlled. I added a roll bar and fiberglass cap. I would really appreciate any help. Thanks
