Say goodbye to sore arms and slow manual greasing. This Alloyman electric grease gun is a beast. It pumps grease at a crazy 6000 to 12,000 PSI, with a flow rate of 5.3 ounces per minute—it can lubricate a tractor in seconds. It switches between a pistol grip for tight spots and a straight grip for heavy-duty jobs with just a button. It holds a ton of grease (20oz/600cc) and you can load it with either bulk grease or standard 14oz cartridges. The kit comes with TWO big 4.0Ah batteries and a charger; one charge can grease up to 12 tractors. There's a long 39-inch flexible hose to reach awkward fittings, a built-in LED light to see what you're doing, and even a shoulder strap. Perfect for farmers, equipment operators, or any DIYer with a lot of machinery to maintain.
