Stillwell Tradesman Vaquero 7K Self-Contained Hydraulic A-Frame Jack
An all-in-one hydraulic solution designed to replace traditional manual hand-crank jacks with effortless, integrated 12V power.
Overview
The Stillwell SJ003B1DEVQ Tradesman unit is a heavy-duty hydraulic jack engineered for high-frequency use on work trailers. Unlike standard hydraulic setups that require mounting a separate pump box and running hydraulic lines, the Vaquero houses everything inside the jack head. This "plug-and-play" design makes it the ultimate upgrade for dump trailers, equipment haulers, and utility trailers.
R&P Service Insight
We recommend this jack for professionals who unhook frequently. It saves time and physical strain compared to manual jacks.
- High Power: Bucher pump capable of over 10,000 lbs force.
- Compact: No external plumbing or bulky reservoir boxes required.
- Safety: Includes a manual hydraulic override for peace of mind.
R&P Knowledge Hub: Usage & Operation
Operation: Use the included 15-foot corded remote to raise or lower the trailer. Ensure your battery is fully charged for peak performance.
Emergency Override: In the event of power loss, locate the override valve on the pump. Pull the knob and turn 1/4 to lock open, allowing the jack to retract under the trailer's weight.
System Bleeding: If the jack feels "spongy," extend it 1/4 of the way and retract fully. Repeat 3–5 times to cycle air back to the reservoir.
Maintenance: Check fluid only when fully retracted. Use ATF (Dexron III) for top-offs and grease the inner leg seasonally to prevent corrosion.
R&P Installation Insight
Installation is straightforward for anyone comfortable with basic 12V wiring and bolt-on components.
- Mounting: Drops into standard 2.25" A-frame coupler holes; uses standard 3-bolt pattern.
- Electrical: Connect directly to a 12V Deep Cycle battery. Ensure a clean ground through mounting bolts.
- Protection: Custom-molded cover protects internal electronics from rain and debris.
