Stihl 251 vs 250 Differences (5 Pro Arborist Insights)

Why This Matters: Value Beyond the Price Tag

Before we dive into the nitty-gritty of engine specs and bar lengths, let’s address the elephant in the room: cost. It’s easy to get caught up in the initial purchase price, but the true cost of a chainsaw goes far beyond that. We need to consider fuel consumption, maintenance, repair costs, and even the potential increase in productivity that a more efficient saw can provide.

I remember one particularly brutal winter a few years back. My old, unreliable chainsaw was constantly breaking down, costing me time and money on repairs. I finally bit the bullet and invested in a more modern, fuel-efficient model. While the initial investment was higher, the reduced downtime and lower fuel bills more than made up for it in the long run. That experience taught me a valuable lesson: value isn’t just about the cheapest price; it’s about the best return on investment.

1. The Pro Arborist Perspective: Key Differences Analyzed

Let’s get down to brass tacks. What are the actual differences between the Stihl MS 251 and the MS 250? Here’s a breakdown from the perspective of someone who uses these tools professionally:

• Engine Power: While both saws feature similar engine displacement, the MS 251 often boasts slightly improved power output. This translates to faster cutting speeds and the ability to handle slightly larger diameter wood. From a professional standpoint, this small increase in power can save significant time on larger jobs.

• Fuel Efficiency: The MS 251 typically incorporates newer engine technology, resulting in better fuel efficiency. This is a major consideration for professionals who use their saws for extended periods. Less fuel consumption means less money spent at the pump and fewer interruptions for refueling.

• Emissions Standards: The MS 251 is generally designed to meet stricter emissions standards than the older MS 250. This is increasingly important in many regions due to environmental regulations.

• Anti-Vibration System: While both saws have anti-vibration systems, the MS 251 often features improved vibration dampening. This reduces operator fatigue, allowing for longer working periods and increased productivity.

• Ease of Maintenance: Some users find the MS 251 slightly easier to maintain due to design improvements. This can translate to lower long-term maintenance costs.

2. The Cost of Ownership: A Deep Dive into the Numbers

Now, let’s get to the heart of the matter: the cost. To understand the true cost of ownership, we need to break it down into several key components:

• Initial Purchase Price: This is the most obvious cost. As of today, the Stihl MS 251 typically retails for around $400 – $500, while a used MS 250 can be found for $250 – $400, depending on condition. These prices may vary significantly based on your location, retailer, and any ongoing promotions.

• Fuel Costs: This is a recurring expense that can add up quickly. Let’s assume you use your chainsaw for 20 hours per year. The MS 251 might consume 0.8 gallons of fuel per hour, while the MS 250 might consume 1 gallon per hour. At an average fuel price of $4 per gallon, the MS 251 would cost $64 per year in fuel, while the MS 250 would cost $80. This difference of $16 per year might seem small, but it adds up over the lifespan of the saw.

• Oil Costs: Chainsaw oil is essential for lubricating the chain and bar. A gallon of high-quality chainsaw oil typically costs around $20-$30. Depending on your usage, you might use 1-2 gallons per year.

• Maintenance Costs: This includes routine maintenance like sharpening the chain, cleaning the air filter, and replacing spark plugs. You can perform some of this maintenance yourself, but more complex repairs might require a professional. I recommend getting the chainsaw serviced at least once a year by a certified technician. This typically costs around $50-$100.

• Repair Costs: This is the unpredictable cost. Chainsaws can break down due to various reasons, from worn-out parts to accidental damage. Repair costs can range from a few dollars for a minor fix to several hundred dollars for a major overhaul.

• Chain Replacement: Chains wear out over time and need to be replaced. A good quality chainsaw chain typically costs around $20-$40.

• Bar Replacement: The chainsaw bar can also wear out or become damaged. A new bar typically costs around $50-$100.

• Safety Gear: Don’t forget to factor in the cost of safety gear, including a helmet, eye protection, ear protection, gloves, and chaps. This can easily add up to $100-$200.

• Storage Costs: If you don’t have a suitable place to store your chainsaw, you might need to purchase a storage container or build a small shed.
