Description
Every farmer knows there’s nothing worse than a bolt that won’t budge or a pivot point that’s seized up when you’re trying to get equipment ready for the next field. This classic WD-40 penetrating oil with the Smart Straw system gives you the precision you need to get right into tight spots and the power to break loose stuck parts that have been sitting all winter.
What You’re Getting
- Flip-up Smart Straw gives you pinpoint accuracy for tight spaces or spray wide for larger areas
- Penetrates rust and corrosion to free up stuck bolts, hinges, and mechanisms
- Displaces moisture to prevent further rust and corrosion
- Leaves a light protective film that keeps parts moving smoothly
- 400ml can provides plenty of coverage for multiple jobs around the farm
Built for Real Farm Work
Whether you’re working on tillage equipment in the spring, maintaining hay equipment through the summer, or winterizing implements in the fall, this is the go-to solution for stuck, squeaky, or corroded parts. It works on everything from combine header pivots to planter gauge wheels, gate latches to PTO shafts.
Made to Last
The original WD-40 formula has been trusted by farmers and mechanics for decades because it works reliably in all kinds of weather conditions. The Smart Straw system is built tough enough to handle shop use without breaking off or getting clogged with debris.
Good to Know
The flip-up straw stays attached to the can, so you won’t lose it when you need precision spraying. For really stubborn bolts, give the WD-40 a few minutes to soak in before applying torque. Keep a can in your toolbox and another in the shop – you’ll find yourself reaching for it more often than you’d expect.
