Write the job list first
List the jobs you expect to do during a normal year, from mowing and moving material to pulling an existing implement. Mark each job as essential, occasional, or a future possibility. This keeps an appealing specification from becoming a substitute for a real requirement.
For every essential job, note the implement you already own or intend to buy. Record its stated requirements rather than guessing from its width or appearance.
Make a comparison sheet
Give each candidate a column for horsepower rating type, transmission, drive configuration, implement compatibility, overall dimensions, and asking price. Use an unknown marker for missing information. An empty cell is a question to investigate, not evidence that a feature is absent.
Add practical limits such as gate width, storage height, access to service, and transport arrangements. A tractor that fits the work but cannot fit your property is not a useful finalist.
Keep the finalists honest
Choose three to five candidates and write one reason each belongs on the list. Then record the biggest unresolved question about each machine. Use Tractor Stack to organize the comparison and confirm the final configuration against the actual tractor and its manufacturer documentation.
