Contractors and construction companies may find it thrilling to come across a Cat 140M Grader For Sale when searching through the market to purchase heavy machinery. The 140M is the most reliable, has the best grading accuracy, and is a well-built machine, which makes it very popular in both large and medium-sized projects. However, before signing the deal, it is important to ask the right questions so that you are not only paying a fair price but also that you are getting a machine that will be of benefit to you in the long run.

1. How Many Operating Hours Are on the Machine?

One of the most revealing factors of wear and tear on a grader is operating hours. Although Caterpillar machines are durable, each hour of use increases the possible maintenance needs.

  • The fewer hours, the better, but a grader with more hours that is well-maintained can be a good purchase.
  • Compare the reading of the hour meter with the age of the machine to see whether the usage is consistent.
  • Watch out for low hours on an older model, which may indicate odometer rolling back or long periods of idling.

2. What Is the Maintenance and Service History?

An extensive service history is a health report of what you are about to buy.

  • Ensure that you subject the grader to routine oil changes, filter replacements, and routine checks.
  • Inspect to see signs of significant component replacements, like the transmission or engine, which may be a sign of long-term reliability.
  • Confirm whether technicians used original Caterpillar components for repairs, as these deliver better performance and retain value better than aftermarket replacements.

3. Has the Grader Been Involved in Any Major Repairs or Accidents?

Harsh environments usually subject heavy equipment to accidents or structural failures.

  • Ask the seller whether the grader has been repaired in any major way other than routine maintenance.
  • Check the frame, moldboard, and articulation joint to see the evidence of welding or reinforcement that may indicate prior damage.
  • Authorized service centers should perform repairs to ensure they achieve the right standards.

4. What Attachments and Features Are Included?

The Cat 140M Grader for Sale can be equipped with multiple attachments that can increase its performance, including rippers, scarifiers, or snow wings.

  • Ensure that you check whether attachments are part of the listed price or not.
  • Inspect the functionality of all hydraulic and control systems associated with attachments.
  • Make sure that any additional features, such as advanced GPS grading systems, are functioning and current.

5. Can I Inspect and Test the Machine Before Purchase?

However well the paperwork is done, a practical inspection is necessary.

  • Test the engine start-up of the machine, smoothness at idle, and power at load.
  • Test hydraulic response, particularly in lifting or tilting the moldboard.
  • Operate the grader to feel abnormal vibrations, steering slack, or ineffective brakes.
  • You may want to seek the services of an independent equipment inspector to give an objective report.

6. What Is the Asking Price Compared to Market Value?

Price is often the final deciding factor, but it should be based on more than just the seller’s offer.

  • Compare similar Cat 140M Grader for Sale listings in your region to gauge fair market value.

  • Factor in age, hours, condition, and included attachments when assessing the deal.

  • Negotiate respectfully, using your research and inspection results as leverage for a fair price.
