Farm Pressure Washers and Cleaning Equipment: Choosing the Right Machine for Agricultural Work
Introduction
Few workplaces put cleaning equipment through as much as a farm. Muck, mud, grease and dust build up on tractors, trailers and implements, in livestock buildings and parlours, and across concrete yards. Machines need to cope with long days, rough ground, cold weather and, often, buildings with no mains power nearby.
Choosing the right pressure washer and cleaning equipment saves time every day and helps keep machinery and buildings in good order. This guide looks at the machines we supply for farms and the jobs each one suits best.
Start with your power supply
Before choosing a machine, think about where it will be used:
• No mains power in fields, outbuildings or remote yards points towards a petrol machine.
• Single-phase power (a standard 230V supply) suits many electric cold and hot water machines.
• Three-phase power (400V), found in many larger farm workshops and dairies, opens up more powerful electric hot water machines.
Getting this right first narrows down the options quickly.
Petrol pressure washers for work anywhere on the farm
Petrol cold water pressure washers can go wherever the work is, with no cable to run and no socket needed.
Evolution 1 13150. A petrol pressure washer delivering 150 bar and 13 litres per minute, built on a robust trolley chassis and weighing 42.8kg. It is designed for jobs such as agricultural machinery and equipment, yard and hard surface cleaning, and remote or off-grid locations.
Evolution 2 21200pHR. A heavier-duty petrol machine delivering 200 bar and 21 litres per minute, with a 1450rpm gearbox drive, a heavy-duty powder-coated trolley and large wheels for rough terrain. It also has an external chemical injector. It is designed for agricultural and plant machinery and heavy-duty yard and hardstanding cleaning, making it a strong choice for larger farms and contractors.
Electric cold water for the yard and workshop
Where mains power is available, an electric cold water machine is quieter and simpler to run than a petrol model.
Dirt Driver Bulldog A/S. A rugged electric cold water pressure washer delivering 110 bar and 12 litres per minute on a 230V single-phase supply. It has a heavy-duty steel frame, a slow-speed ceramic piston pump and auto stop protection, and is designed for uses including yards, vehicle washing and agricultural sites.
Hot water for grease, oil and livestock areas
Cold water shifts mud and muck well, but hot water is far quicker on grease, oil and stubborn dirt on machinery, and in areas where fats build up.
Dirt Driver Sapphire 1500. A hot and cold water pressure washer delivering 100 bar and 12 litres per minute on a 230V single-phase supply. It has a 25-litre detergent tank and is designed for jobs including agricultural equipment and machinery, vehicle washing and workshops.
Dirt Driver Sapphire 2200. A more powerful hot and cold water machine delivering 150 bar and 15 litres per minute on a 400V three-phase supply. It is designed for heavy grease and oil removal, including agricultural buildings and machinery, and is commonly specified by agricultural contractors and transport depots.
Concrete yards: flat surface cleaners
Cleaning large concrete yards with a lance takes time and can leave uneven, striped results. A flat surface cleaner attaches to a pressure washer and cleans a wide strip evenly as you walk.
Turbo Devil TD520. A stainless steel surface cleaner with a 21-inch cleaning width, designed for large flat areas such as industrial yards and hardstanding. Check that your pressure washer is compatible before use.
Workshops and flooded areas: wet vacuums
Farm workshops, stores and offices still need everyday cleaning, and heavy rain can leave standing water in buildings.
Numatic WV1800DH. A heavy-duty wet pick-up vacuum with a 70-litre capacity and a dump hose for easy emptying, built for industrial use.
Barn and building gutters: high-level vacuums
Barns, sheds and farmhouses have long runs of gutters that fill with leaves and debris. Clearing them from ladders is slow and risky.
skyVac Interceptor. Powered by a 5.5hp Honda petrol engine, it needs no electrical supply and can clear gutters up to 40ft from the ground, with a 90-litre container. That makes it practical for buildings spread across a farm.
Washing down responsibly
Wash water from machinery and buildings can carry soil, oil and other contaminants, so it should not run into watercourses or surface water drains. Plan where your wash area drains to, and check the current guidance from your environmental regulator.

FAQs
What is the best pressure washer for a farm?
It depends on the job and your power supply. Petrol machines such as the Evolution 1 and Evolution 2 work anywhere, while hot water machines such as the Dirt Driver Sapphire range are best for grease and oil.
Do I need a hot water pressure washer on a farm?
If you regularly clean greasy machinery or areas where fats build up, hot water saves a lot of time. For mud and muck, a cold water machine is often enough.
Which pressure washer works without mains power?
Petrol models such as the Evolution 1 13150 and Evolution 2 21200pHR need no mains supply, so they can be used anywhere on the farm.
What is the best way to clean a concrete yard?
A pressure washer with a flat surface cleaner such as the Turbo Devil TD520 cleans large concrete areas faster and more evenly than a lance.
Can farm building gutters be cleaned from the ground?
Yes. The skyVac Interceptor clears gutters up to 40ft from the ground and runs on petrol, so it does not need mains power.
