7 Generator Accessories to Keep Your Farm Running

A flash of lightning, a rumble of thunder, and then silence—the kind of quiet that means the well pump isn’t running and the brooder lamps just went cold. On a farm, a power outage isn’t an inconvenience; it’s a direct threat to your animals, your water supply, and your stored harvest. A generator is the heart of your backup plan, but it’s the accessories around it that make it a reliable system instead of just a loud engine in the shed.

Preparing Your Farm for Unexpected Power Outages

Having a generator stored in the barn is a good first step, but it’s only about 25% of the solution. True preparedness means building a complete, safe, and ready-to-go power system. When the lights go out, you don’t want to be hunting for a specific cord in the dark or discovering your fuel has gone bad. The goal is a system so well-planned that flipping the switch to backup power is a calm, routine procedure.

This isn’t about over-engineering a solution for a once-a-decade ice storm. It’s about ensuring the core functions of your farm—water for livestock, heat for vulnerable chicks, and refrigeration for your food—can continue uninterrupted. The right accessories turn your generator from a standalone machine into an integrated part of your farm’s infrastructure, ready to deploy at a moment’s notice.

Transfer Switch – Reliance Controls Pro/Tran 2

A transfer switch is the only safe way to connect a generator to your home or barn’s electrical circuits. It isolates your system from the grid, preventing dangerous backfeed that can injure or kill utility workers. It also allows you to power hardwired equipment like a well pump or furnace directly from your breaker panel, eliminating the chaos of running multiple extension cords through doors and windows.

The Reliance Controls Pro/Tran 2 is a manual transfer switch, which is the perfect fit for a small farm. Unlike expensive automatic switches, you are in complete control, and there are fewer complex electronics to fail. This model allows you to pre-select 6 to 10 critical circuits (like your well, freezer, and kitchen outlets) and power them with the flip of a few switches. It’s a robust, no-nonsense unit built for reliability.

Before you buy, know exactly which circuits you need to power and consult a licensed electrician for installation—this is not a DIY job. The electrician will install the switch next to your main panel and run a heavy-gauge wire to an outdoor inlet box where you’ll plug in the generator. This setup is the gold standard for safety and convenience, turning a stressful event into a manageable task.

Heavy-Duty Cord – Southwire 50-Foot 30-Amp Cord

Your generator must be operated at least 20 feet from any building to prevent carbon monoxide poisoning. That means you need a serious power cord to bridge the gap between the generator and your transfer switch inlet box. A standard orange extension cord is a fire hazard and will cause a significant voltage drop, potentially damaging your appliances and the generator itself.

The Southwire 50-Foot 30-Amp Generator Cord is built for this exact task. Its 10-gauge copper wires are thick enough to handle a heavy electrical load over distance without overheating or losing power. The 50-foot length provides ample flexibility for safe generator placement, and the durable, weather-resistant jacket can withstand being dragged across gravel or wet grass.

Make sure the cord’s plug matches your generator’s 240V outlet and your transfer switch’s inlet box, which is typically an L14-30 locking plug for 30-amp service. Don’t be tempted by a cheaper, thinner cord. Investing in a properly gauged cord is a critical safety measure that ensures your generator can deliver the power you need efficiently and without risk.

Fuel Stabilizer – STA-BIL Storage Fuel Stabilizer

The most common reason a generator fails to start is bad fuel. Modern gasoline, especially with ethanol, can begin to degrade in as little as 30 days, gumming up carburetors and fuel lines. When you pull the start cord during an outage, you need absolute confidence the engine will fire up. Fuel stabilizer is the cheap insurance that makes that happen.

STA-BIL Storage Fuel Stabilizer is the industry benchmark for a reason: it works. A small amount added to your gas can when you fill it up keeps the fuel fresh for up to 24 months. It prevents the formation of varnish and corrosive deposits, ensuring your generator’s fuel system stays clean and ready. This is a non-negotiable part of your generator prep.

Make this a habit. Every single can of gasoline you set aside for the generator should be treated with STA-BIL immediately. A small bottle treats dozens of gallons, making the cost per use minimal. Forgetting this step can lead to a costly and time-consuming carburetor cleaning right when you can least afford the downtime.

Essential Generator Safety and Placement Tips

A generator is a powerful tool, but it demands respect. The two biggest dangers are carbon monoxide (CO) poisoning and electrocution. CO is an invisible, odorless gas produced by the engine’s exhaust. Never, under any circumstances, run a generator inside a garage, barn, shed, or basement, even with the doors open.

Proper placement is your primary defense. The generator should be positioned at least 20 feet away from your house and any other buildings. Point the engine exhaust away from all doors, windows, and vents. To protect it from rain or snow, use a purpose-built generator tent or a simple, open-sided canopy. Do not cover it with a simple tarp, as that can restrict airflow and cause overheating.

Maintenance Kit – Generac Scheduled Maintenance Kit

A generator is an engine, and like any engine on the farm, it requires regular maintenance to be reliable. Letting it sit for a year without an oil change or a fresh spark plug is asking for it to fail on the day you need it most. A maintenance kit removes all the guesswork from this essential chore.

A Generac Scheduled Maintenance Kit (or the equivalent from your generator’s manufacturer) is the most straightforward way to get this done. These kits bundle the exact items you need for your specific model, including:

• The correct type and amount of oil
• The right spark plug
• A new air filter
• A funnel and shop towel

This isn’t for commercial users; it’s for the busy hobby farmer who doesn’t have time to cross-reference part numbers. The kit ensures you have everything on hand to complete a full service in under 30 minutes. Schedule this task for late fall, right before the winter storm season begins, to ensure your machine is in peak condition.

Generator Cover – Classic Accessories StormPro Cover

Between uses, your generator is exposed to dust, moisture, insects, and UV rays that can degrade plastic parts and corrode electrical connections. A simple, durable cover is the best way to protect your investment and ensure it stays clean and ready for action. It’s a small detail that speaks to a larger philosophy of keeping your equipment in top shape.

The Classic Accessories StormPro Cover is a solid choice because it’s made from tough, water-resistant fabric designed for outdoor equipment. Unlike a cheap plastic tarp, these covers have built-in air vents that allow moisture to escape, preventing condensation and rust from forming underneath. They are available in a range of sizes to fit most portable generators snugly.

Remember, this type of cover is for storage only. Never run the generator with a storage cover on, as it will immediately overheat. For operation in foul weather, you need a specialized "running cover" or generator tent that allows for proper airflow.

Mobility Kit – Champion Power Equipment Wheel Kit

Portable generators are portable in name only. A mid-sized 5,000-watt unit can easily weigh over 150 pounds—a deadlift you don’t want to attempt in the dark on uneven, muddy ground. A wheel kit transforms the generator from a back-breaking liability into a machine one person can easily and safely maneuver.

Many generators, especially less expensive models, don’t include wheels. A Champion Power Equipment Wheel Kit is a common, easy-to-install upgrade that fits many brands with tubular frames. These kits typically include a pair of never-flat tires, a fold-down handle for leverage, and a support leg. The installation is usually a simple bolt-on process that takes just a few minutes.

Before buying, double-check that the kit is compatible with your generator’s frame design and weight. This is one of the single best quality-of-life upgrades you can make. It encourages you to store the generator in a secure, out-of-the-way location and makes the quarterly task of test-running it far less of a chore.

CO Detector – Kidde Nighthawk Carbon Monoxide Alarm

Even with perfect generator placement 20 feet from your home, shifting winds can push deadly carbon monoxide exhaust into your house through vents or small gaps. A CO detector is your essential, non-negotiable last line of defense. It is the silent alarm that protects your family while you sleep.

The Kidde Nighthawk Carbon Monoxide Alarm with a digital display and battery backup is the right tool for the job. A plug-in-only model is useless in a power outage. The battery backup ensures it keeps working when you need it most, and the digital readout shows you the real-time CO concentration in parts per million (PPM), providing more information than a simple beeping alarm.

Install at least one CO detector on each level of your home, especially near sleeping areas. Test them monthly and replace the batteries annually, at the same time you do your smoke detectors. This device isn’t just an accessory for your generator; it’s a fundamental piece of farm and home safety equipment.

Performing Seasonal Generator System Checks

A generator system’s reliability comes from routine, not reaction. A simple seasonal check-in ensures everything is ready to go long before a storm is on the horizon. This proactive approach prevents the vast majority of startup failures.

Once every three months, wheel the generator out and start it. Let it run for 15-20 minutes with a light load plugged in, like a power tool or a work light. This does two things: it circulates the oil to keep internal engine parts lubricated, and it runs fresh, stabilized fuel through the carburetor to prevent gumming.

Once a year, typically in the fall, perform a full system check. This is when you use your maintenance kit to change the oil, spark plug, and air filter. Inspect your heavy-duty power cord for any cracks or damage. Start the generator, connect it to your transfer switch inlet, and test a few circuits in the house. This 30-minute annual ritual is the key to having a system you can truly depend on.

Creating Your Farm’s Power Outage Action Plan

When the power goes out, adrenaline can make it hard to think clearly. A simple, written action plan, kept near your breaker panel, removes the guesswork and ensures nothing critical is missed. The plan should be a straightforward sequence of events that anyone on the farm can follow.

First, identify your critical loads. This isn’t about powering the whole farm; it’s about survival for a few days. The list should include:

• Well Pump: Water for livestock and home use.
• Freezers/Refrigerators: Protecting hundreds of dollars worth of meat and produce.
• Brooders/Heat Lamps: For young, vulnerable animals.
• Key Outlets: One in the kitchen for a coffee pot or hot plate, and one for charging phones.

Your plan should detail the startup sequence: roll the generator to its safe spot, check the fuel and oil, connect the main cord to the inlet box, start the engine, and then go inside to flip the transfer switch breakers. Having this process written down turns a potential panic situation into a calm, methodical task.
