### **Pros and Cons of buying a Arctic Cat 0728-006 (1991 Prowler 440 Track Drive Shaft)**
#### **Pros**
1. **Reliability and Durability** Arctic Cat is a well-regarded brand known for building robust, long-lasting snowmobiles. The 1991 Prowler 440, in particular, was designed for performance and endurance, making it a solid choice for serious riders.
2. **Track Drive System** The track drive (0728-006) is a key component that ensures smooth power delivery and better traction compared to ski-based systems. This makes it ideal for deep snow, rough terrain, or heavy-duty use.
3. **Classic Design with Modern Capabilities** The Prowler 440 was a high-performance model in its time, featuring a powerful engine (likely a 440cc two-stroke) and a track system that was ahead of its competitors. Restoring or maintaining one can be rewarding for enthusiasts.
4. **Parts Availability** While some older Arctic Cat parts may be harder to find than modern equivalents, the 1991 Prowler still has a dedicated following. Many aftermarket and vintage snowmobile shops carry replacement parts, and online communities (like forums) can help track down rare components.
5. **Potential for Restoration and Customization** If you enjoy mechanical work or modifying vehicles, the Prowler 440 offers opportunities to upgrade components, improve performance, or restore it to like-new condition. This can be both a hobby and a way to extend its lifespan.
6. **Lower Purchase Cost** Compared to newer snowmobiles, a 1991 Prowler 440 with a track drive shaft will likely be significantly cheaper, making it an attractive option for budget-conscious buyers or those looking for a project vehicle.
7. **Track-Based Advantages** Tracks provide better flotation in deep snow, reduced ski wear, and improved stability, which can be beneficial for off-piste riding or heavy-duty use.

#### **Cons**
1. **Age and Wear** A 1991 model is nearly 30 years old, meaning it may have significant wear on critical components like the engine, transmission, track, and suspension. Without proper maintenance, it could require extensive repairs.
2. **Maintenance Requirements** Older snowmobiles, especially two-stroke models, demand more frequent and meticulous maintenance. This includes regular oil changes, track adjustments, chain and sprocket checks, and potential engine rebuilds. If you re not mechanically inclined, labor costs could add up quickly.
3. **Fuel and Emissions Concerns** Two-stroke engines (common in older Arctic Cats) are less fuel-efficient and produce more emissions than modern four-stroke models. They also require a mix of oil and gas, which can be messy and less convenient.
4. **Parts Obsolescence** While some parts are still available, others may be discontinued or difficult to source. You may need to rely on salvage yards, eBay, or specialty shops, which can be time-consuming and expensive.
5. **Resale Value** Vintage snowmobiles, while collectible to some, generally depreciate over time. If you plan to sell it later, the resale value may not justify the investment in repairs or restoration.
6. **Track Drive Specific Challenges** Track systems require regular tensioning, alignment, and replacement of worn components (e.g., track links, sprockets, idlers). Neglecting these can lead to premature failure or poor performance.
7. **Safety and Modern Standards** Older snowmobiles lack modern safety features like electronic fuel injection, advanced suspension systems, or integrated diagnostics. Riding conditions may be less forgiving compared to contemporary models.
8. **Storage and Transportation** Tracks take up more space than skis, making storage and transport more cumbersome. If you don t have a dedicated garage or trailer, this could be a practical drawback.

### **Conclusion**
The Arctic Cat 1991 Prowler 440 with a track drive shaft (0728-006) is a compelling purchase for **enthusiasts, restorers, or riders who prioritize durability and off-piste capability over modern convenience**. It offers a blend of classic performance and track-based advantages that are hard to match in newer models. However, it comes with **higher maintenance demands, potential reliability issues, and the need for mechanical expertise** to keep it running smoothly.
If you re willing to invest time and effort into maintaining or restoring it, this snowmobile can be a rewarding project with long-term enjoyment. On the other hand, if you prefer low-maintenance, high-performance, or environmentally friendly options, a newer model with a four-stroke engine and modern features may be a better fit.

**Alternative Considerations:**- If you like the track drive but want something newer, look for Arctic Cat s modern track models (e.g., the Arctic Cat 850 or 1050).
- For a balance of performance and maintenance, consider a well-maintained used four-stroke snowmobile from the 2000s or later.
- If restoration is the goal, factor in a realistic budget for parts and labor some projects can cost more than the vehicle itself.
