We Buy Your Generator
- Finance Available, on all new generators.
Agricultural work depends on electricity long before a power cut becomes an emergency. Milking equipment, livestock ventilation, water pumps, irrigation systems, refrigeration, grain handling, and automated controls may all require a dependable supply to protect animals, crops, stored produce, and daily productivity. Depending on the model and installation, modern generator systems may offer automated controls, monitoring, and load management features that can improve operational efficiency. This can be particularly useful on agricultural sites where essential equipment needs to respond automatically to changes in power availability or demand.
Bellwood Rewinds supplies new and used agricultural generators for farms, rural businesses and off-grid locations throughout the UK. Our available range includes diesel generators, PTO generators, silenced units and mobile models suitable for standby power, seasonal demand and continuous operation.
Browse the agricultural generators available below, or speak to our engineering team if you need help comparing generator size, phase, fuel, mobility and operating duty. We can also advise whether purchasing a generator or arranging generator hire is the most practical option for your agricultural operation.

The correct size depends on the equipment’s running and starting loads and whether several systems need to operate simultaneously. Pumps, fans, refrigeration, grain dryers, and milking machinery can draw high starting currents, so the assessment needs to consider more than the normal running wattage.
A small-scale farmer may only need a generator for a few essential systems, while large farms may require significantly more capacity to support automated equipment, livestock facilities, and machinery across the site. Bellwood can review your load schedule and help identify a suitable generator with an appropriate kW or kVA rating.
Diesel generators are often well-suited to sustained loads, permanent standby applications, and regular agricultural use, while PTO generators can provide flexible, cost-effective operation when a compatible tractor is already available. Portable or petrol generators may be more appropriate for lighter or short-term requirements.
The best generator for agricultural purposes depends on the equipment being powered, operating hours, mobility, fuel arrangements and site conditions. Bellwood can provide tailored solutions based on the farm’s specific requirements, rather than recommending equipment solely on capacity.
For farms that depend heavily on electrically powered equipment, a backup generator can provide an important layer of resilience when the normal commercial electrical supply is interrupted. A power cut can affect refrigeration, ventilation, water pumps, milking equipment and automated systems controlled by the farm’s electrical infrastructure.
Reliable backup power can help ensure farms maintain essential operations, protect livestock welfare and reduce the risk of produce spoilage or production delays. The appropriate backup arrangement depends on which systems are critical and how quickly they need to be restarted after an outage.
Yes, provided the generator is correctly sized for the combined running and starting demand. Agricultural generators can support irrigation pumps, milking equipment, refrigeration, ventilation, and automated feeding systems for livestock, as well as lighting, communications, and other farm infrastructure.
When several systems need to operate together on a day-to-day basis, load sequencing may help prevent large motors from starting simultaneously. The generator and associated controls should be designed around the actual farming operation to provide a steady and reliable power supply.
Runtime depends on the generator’s duty rating, fuel tank capacity, connected load, fuel consumption, and maintenance condition. There isn’t a reliable universal runtime for diesel generators because tank size, generator output and operating load can vary considerably between models.
For continuous or prolonged use, fuel storage, refuelling arrangements, and generator efficiency should be included in the specification. Choosing the correct generator size can also support more efficient operation than running an unnecessarily oversized unit under a very light load.
Service intervals depend on running hours, operating environment and the manufacturer’s recommendations. Generators used regularly on farms may require more frequent inspection than standby units because dust, moisture, temperature changes and long running periods can place additional demands on components.
Routine maintenance should include checks of fluids, filters, batteries, belts, hoses, electrical connections and controls. Planned servicing helps support long-term reliability and reduces the likelihood of a fault interrupting essential farming operations.
Reliable power solutions give agricultural businesses greater protection against unexpected outages and can support essential processes in remote or off-grid locations. This can be particularly important where livestock welfare, refrigeration, irrigation, grain handling or automated equipment depends on a continuous electrical supply.
For some farms, a generator becomes a mainstay power source for remote operations; for others, it is primarily standby protection. Bellwood can assess the intended duty and recommend a solution designed around the farm’s actual operating requirements.
No two farms use power in exactly the same way. A dairy unit may need to protect milking, cooling and washing systems, while an arable agricultural business may require power for grain dryers, conveyors, irrigation pumps or remote field operations. Poultry and livestock sites can be particularly sensitive because ventilation, feeding, heating, and water systems may rely on electrically powered components and automated controls that draw on the farm’s electrical infrastructure.
Across the agricultural industry, reliable power is therefore about more than keeping lights on. The right generator should support the farming operations that cannot safely stop, maintain a steady supply to essential equipment and help minimise disruption when the electrical grid or local power grid fails.
The right farm generator must therefore be selected based on critical loads, starting currents, operating hours, and the consequences of an interruption. Bellwood helps customers move from an equipment list to a practical power solution rather than choosing a unit based on headline kVA alone.
