A proper used motor grader inspection checklist therefore goes well beyond paint and the hour meter. If you are wondering what to check when buying a used grader, the short answer is this: confirm the machine&#8217;s identity and service history, inspect the engine, drivetrain, hydraulics, frame, articulation, circle, moldboard, tires and controls, then finish with a controlled operating test.

What is the most important thing to inspect on a used motor grader?<\/b><\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">A: Overall mechanical condition: how the engine, drivetrain, frame, articulation, circle, drawbar, and moldboard work together. Your intended use decides which findings matter most.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"2_How_many_hours_are_too_many_for_a_used_motor_grader\"><\/span><span style=\"font-size: 14pt;\"><b>2. How many hours are too many for a used motor grader?<\/b><\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">A: There is no universal cutoff. Maintenance records, application, corroborated hours, major component condition, and inspection results say more than the meter alone.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"3_Should_I_get_an_independent_inspection_before_buying_a_used_grader\"><\/span><span style=\"font-size: 14pt;\"><b>3.
