Buying new transmission gears for a John Deere 6668 tractor with a 4600 transmission involves considering several factors to help make an informed decision. Here are some pros and cons of this purchase:

1. Enhanced Performance: New transmission gears can improve the overall performance of the tractor. This includes smoother shifting, better acceleration, and increased efficiency.

2. Durability: New gears are designed to last longer than used or rebuilt gears. This can save money in the long run by reducing the need for frequent repairs or replacements.

3. Warranty: New transmission gears often come with a warranty that covers manufacturing defects or other issues. This can provide peace of mind and protect against potential repair costs.

4. Compatibility: New gears are specifically designed for the John Deere 6668 tractor with a 4600 transmission. This ensures a perfect fit and eliminates the risk of compatibility issues.

1. Cost: New transmission gears can be expensive. The cost of purchasing and installing new gears may be a significant investment.

2. Time: Installing new transmission gears requires a significant amount of time. This may involve removing the old gears, preparing the transmission for the new gears, and then installing the new gears.

3. Expertise: Installing new transmission gears requires specialized knowledge and expertise. This may involve hiring a professional mechanic or dealer to perform the installation.

In conclusion, buying new transmission gears for a John Deere 6668 tractor with a 4600 transmission can provide enhanced performance, durability, and compatibility. However, this investment comes with a significant cost, time commitment, and expertise requirement.

If the tractor is used frequently or for heavy-duty applications, the benefits of new transmission gears may outweigh the costs. However, for occasional use or lighter applications, the cost and time investment may not be justified.

A potential alternative to consider is rebuilt or used transmission gears. These options can be more cost-effective but may come with compatibility and durability concerns. Ultimately, the decision to purchase new transmission gears depends on the specific needs and budget of the tractor owner.
