View 87247 productHusky Brute Electric Tongue Jacks: 82022, 87247 & Parts
An electric trailer tongue jack raises and lowers the coupler without repeated hand cranking. The Husky Brute 87247 and Super Brute 82022 both use a 12-volt ball-screw drive with 18 inches of powered travel, but they have different rated loads and operating equipment. If you need a replacement jack, switch, manual crank or drop leg, start with the part number on your existing unit.
Compare the two Husky electric jacks
| Specification | Brute 87247 | Super Brute 82022 |
|---|---|---|
| Husky model | HB4500 | HSB5000R |
| Rated lift | 4,500 lb | 5,000 lb |
| Powered stroke | 18 in | 18 in |
| Drop-leg adjustment | 6 in | 6 in |
| Power | 12V DC | 12V DC |
| Outer tube | 2¼ in | 2¼ in |
| Remote control | Not included | Included |
The 18-inch stroke is the motor-driven jack movement; the 6-inch drop leg provides a separate manual height adjustment. Together they give up to 24 inches of total adjustment when used as directed. Neither jack's 4,500- or 5,000-lb lifting rating changes the trailer's towing capacity.

Husky's Brute 87247 installation and replacement-parts manual identifies the switch, rubber access covers, foot assembly, circuit breaker and emergency crank in its exploded drawing. The separate Super Brute 82022 installation and parts manual shows its remote-equipped model and the correct accessory part numbers. Use the full jack number on the original label to select parts; the upper housings and control systems are not necessarily interchangeable.

The low-friction ball screw allows the loaded jack to move quickly if its brake is released. Always disconnect electrical power and fully engage the emergency crank before releasing the brake. Hold the crank securely throughout the manual operation, then re-engage the brake before removing either tool. Follow the exact sequence shown in the Husky manual; do not remove the brake-release lever or try to crank a powered jack without first isolating its electrical supply.
Electrical connection and maintenance
The 82022 installation instructions specify a 12V DC supply, a 30-amp manual-reset breaker near the battery, and a six-foot 10-gauge lead. For an aluminum trailer frame, the instructions require a dedicated ground from a mounting bolt to battery negative. Mounting uses three 3/8-inch Grade 5 bolts at the A-frame, with appropriate washers and frame support below the coupler. Follow the applicable 87247 manual for its wiring and mounting rather than transferring instructions blindly between models.
If a jack stops operating, check the battery voltage, breaker, ground and trailer connection before assuming a motor failure. The manuals also distinguish a tripped breaker from the normal Smart Stop at either end of travel. Keep the extended inner tube clean and lubricate its exterior as Husky directs; do not open the sealed ball-screw assembly for routine greasing.
Before ordering
- Find the Husky part number and determine whether your jack is an HB4500 (87247) or HSB5000R (82022).
- Check the loaded tongue weight, A-frame opening, mounting bolt pattern and wiring supply.
- For a component repair, match the exact part number to the correct Husky exploded diagram. A switch from the 87247 service list is not automatically a repair part for the remote-equipped 82022.
- Use the trailer manufacturer’s approved support points when lifting or replacing a jack. Never work beneath a trailer supported only by the tongue jack.
