Buying a Caltric TCU20773 Extension Spring for Deere 647, 647a, 657, 657a, 667, 667a, 717, and 717e Tractors: Pros, Cons, and Recommendation

The Caltric TCU20773 extension spring is a commonly replaced part for various Deere tractor models, including 647, 647a, 657, 657a, 667, 667a, 717, and 717e. In this text, we will discuss the pros and cons of purchasing this extension spring from Caltric and conclude with a recommendation.

1. Cost-effective: Caltric's TCU20773 extension spring is often more affordable compared to the original equipment manufacturer (OEM) part. This can save tractor owners a significant amount of money, especially for those who frequently encounter issues with their extension springs.

2. Availability: Caltric's aftermarket parts, including the TCU20773 extension spring, are widely available through various retailers and online marketplaces. This ensures that tractor owners can easily access and purchase the part when needed.

3. Compatibility: Caltric's TCU20773 extension spring is specifically designed for the mentioned Deere tractor models, ensuring a perfect fit and proper functionality.

1. Quality concerns: Some tractor owners have reported that aftermarket parts, such as the Caltric TCU20773 extension spring, may not last as long as the OEM part. However, it is essential to note that the durability of aftermarket parts can vary significantly between brands and individual products.

2. Warranty: OEM parts typically come with a warranty, providing peace of mind for the tractor owner. Caltric's aftermarket parts, including the TCU20773 extension spring, do not come with the same level of warranty coverage, which can be a concern for some.

When deciding whether to purchase a Caltric TCU20773 extension spring for a Deere tractor, it is essential to weigh the pros and cons. The primary advantages include cost savings, availability, and compatibility. The disadvantages include potential quality concerns and the lack of a warranty. Ultimately, if cost is a significant factor and the tractor owner is confident in the reliability of aftermarket parts, purchasing a Caltric TCU20773 extension spring may be the best choice. However, if the tractor owner values the peace of mind that comes with an OEM part and its warranty, they may opt to pay the higher price for the original equipment.

If you are comfortable with the potential trade-offs and believe that the cost savings outweigh the potential drawbacks, Caltric's TCU20773 extension spring can be a suitable option for your Deere tractor. Make sure to purchase the part from a reputable retailer to ensure its authenticity and quality. If you prefer the added peace of mind that comes with an OEM part and its warranty, consider contacting your local Deere dealer for a quote.
