New parts increase the value of a used tractor if they involve significant change. Like changes to most other high-value properties, repairs and replacements improve the lifespan or usefulness of a used tractor. The size of the increase in value depends on the nature of the new parts, notes Ssbtractor.com.
Engine parts, seats and tires are some of the new parts that can cause a significant increase in value. Replacements that involve minor changes, such as tractor lights, do not add significantly to the value of a used tractor. It is important to maintain a record of all the new parts added to a tractor to be able to justify any increases in value at a later date.
