We just replaced a water pump on our 5020 at the church. Purchased new in 1980. Now has over 2800 hours and still does not use any oil. Parts for the hood and such may be problematic but the water pump was ordered and here in less than a week. We have only used this unit for mowing our 5 acre property and currently pull a 5' Bush Hog RFM. We've replaced the tires due to age and now the water pump and hoses in 35 years of service. They are good tractors and very reliable.
