Antique Sears Chainsaw History (5 Rare Models)

Sears, Roebuck and Co., a name synonymous with American retail, also played a significant role in the history of logging and firewood preparation. While not manufacturers themselves, Sears partnered with various chainsaw producers to offer their own branded versions, often at more accessible price points. These “Craftsman” chainsaws, sold through their catalog and retail stores, brought the power of mechanized woodcutting to a wider audience. Identifying the rarest models requires a bit of detective work, sifting through old catalogs, and piecing together information from collectors and enthusiasts. I’ve spent countless hours doing just that, and here are five models that stand out in terms of rarity and historical significance.

1. The Craftsman/David Bradley 101.7400 (circa 1950s)

David Bradley Manufacturing Company, a subsidiary of Sears, primarily focused on farm equipment. The 101.7400 represents their foray into chainsaws, making it a unique and relatively scarce find.

Why it’s rare: Short production run, association with a primarily agricultural brand, and the age itself contribute to its rarity. Many were likely used hard and discarded, leaving few surviving examples in good condition.
Technical Specifications (estimated):
- Engine: Single-cylinder, two-stroke (likely around 3.5-4 horsepower)
- Bar Length: Typically 20-24 inches
- Weight: Heavy, likely exceeding 25 pounds
- Fuel Mix Ratio: Typically 16:1 (gasoline to oil – always double-check the specific manual for this critical detail!). Using the wrong fuel mix is a surefire way to damage a vintage engine.
- Chain Type: Likely .404 pitch, but verification is essential.
Identifying Features: Look for the “Craftsman” logo alongside the David Bradley nameplate. The engine shroud design is distinctive, often featuring a prominent air filter housing.
My Personal Experience: I once stumbled upon one of these at an antique tractor show. The owner, a retired farmer, had meticulously restored it. He recounted stories of using it to clear land for his farm, a testament to its ruggedness. He emphasized the importance of using the correct fuel mix and meticulously cleaning the carburetor, two crucial aspects of maintaining these old machines.

2. The Craftsman 3.7 (circa 1960s)

The Craftsman 3.7, also known as the model 917.60740, represents a step forward in chainsaw design. While not as inherently rare as the David Bradley model, finding one in good working condition is becoming increasingly challenging.

Why it’s rare: Its age, coupled with the fact that many were used extensively for firewood cutting, has led to a decline in the number of surviving examples.

Maintaining and Restoring Antique Sears Chainsaws

Finding these rare chainsaws is just the first step. Preserving them requires a commitment to proper maintenance and, in some cases, restoration. Here are some key considerations:

Identifying Parts

One of the biggest challenges in restoring antique chainsaws is finding replacement parts. Here are some resources:

Online Auctions: eBay and other online auction sites are often a good source for used parts.
Chainsaw Forums: Online forums dedicated to chainsaws and small engines can be valuable resources for finding parts and advice.
Antique Tool Dealers: Specialized dealers who focus on antique tools may have a selection of chainsaw parts.
Salvage Yards: Don’t overlook salvage yards or small engine repair shops. You might be surprised at what you can find.

Fuel and Lubrication

As mentioned earlier, using the correct fuel mix is critical for two-stroke engines. Here are some general guidelines:

Fuel Mix Ratio: Consult the chainsaw’s manual for the recommended fuel mix ratio. If the manual is unavailable, a general rule of thumb is 16:1 for older models (pre-1960s) and 32:1 or 40:1 for newer models. Always err on the side of using more oil than less.
Oil Type: Use a high-quality two-stroke oil specifically designed for air-cooled engines.
Bar Oil: Use a dedicated bar and chain oil to lubricate the chain and bar. This oil is designed to cling to the chain and prevent it from overheating.
Data Point: Insufficient chain lubrication can lead to premature wear of the chain and bar, as well as increased risk of kickback. Kickback is a sudden and forceful movement of the chainsaw bar, which can cause serious injury.

Carburetor Cleaning and Adjustment

A dirty or poorly adjusted carburetor is a common cause of starting and running problems in antique chainsaws. Here’s a basic overview of the process:

Disassembly: Carefully disassemble the carburetor, noting the location of all parts.

Reassembly: Reassemble the carburetor, using new gaskets and diaphragms if necessary.
Adjustment: Adjust the carburetor according to the manufacturer’s specifications. This typically involves adjusting the high-speed and low-speed mixture screws. Refer to the manual for specific adjustment procedures.
Practical Tip: Before disassembling the carburetor, take photos or videos to document the process. This will make reassembly much easier.

Ignition System

The ignition system is responsible for creating the spark that ignites the fuel-air mixture in the engine. Common problems include:

Faulty Spark Plug: Replace the spark plug with a new one of the correct type.
Weak Ignition Coil: Test the ignition coil with a multimeter. If it’s weak, replace it.
Dirty or Corroded Points (if applicable): Clean or replace the points.
Incorrect Point Gap (if applicable): Adjust the point gap according to the manufacturer’s specifications.

Safety Considerations

Operating antique chainsaws can be dangerous. Here are some important safety precautions:

Personal Protective Equipment (PPE): Always wear appropriate PPE, including a chainsaw helmet, safety glasses, hearing protection, gloves, and chainsaw chaps.
Chain Brake: Many antique chainsaws lack chain brakes. Exercise extreme caution when operating them.
Kickback: Be aware of the risk of kickback and take steps to avoid it.
Safe Cutting Practices: Use proper felling and bucking techniques.
Clear Work Area: Ensure that the work area is clear of obstacles and bystanders.
Never Work Alone: Always work with a partner in case of an emergency.
Data Point: According to the Consumer Product Safety Commission (CPSC), chainsaws cause tens of thousands of injuries each year. Take safety seriously!

Industry Standards and Forestry Regulations

When working with chainsaws and wood processing, it’s important to be aware of relevant industry standards and forestry regulations. These regulations vary depending on your location, but here are some common areas of concern:

Tree Felling Permits: Many jurisdictions require permits for felling trees, especially on public land.
Firewood Regulations: Regulations may govern the transportation and sale of firewood to prevent the spread of invasive species.
