Description
If your A-frame jack is getting hard to crank or the handle feels like it’s spinning without raising the trailer, chances are the internal gears are worn out. Nothing’s more frustrating than trying to unhitch your grain wagon or livestock trailer when the jack won’t lift the tongue properly. This replacement gearbox and crank assembly gets your jack working like new again, so you can focus on the work instead of fighting with your equipment.
What You’re Getting
- Complete gearbox assembly with rack-and-gear mechanism for smooth, reliable lifting action
- Side-wind crank handle design that keeps you clear of the trailer tongue while operating
- 750 lb capacity that handles most farm trailers and implements without breaking a sweat
- A-frame mount style that bolts directly to your existing jack bracket
- Heavy-duty construction built to handle the constant use farm trailers see
Built for Real Farm Work
This assembly is designed for A-frame trailer jacks commonly found on grain wagons, hay trailers, livestock trailers, and implement trailers around the farm. Whether you’re hooking up to move corn to the elevator, pulling hay from field to barn, or moving equipment between farms, this jack handles the daily lifting and lowering that keeps your operation moving.
Made to Last
Farm trailers don’t get babied, and neither do their jacks. This gearbox assembly features durable gearing that stands up to the dirt, moisture, and heavy use that comes with agricultural work. The side-wind design puts less stress on the mechanism compared to top-wind jacks, helping it last longer in tough conditions.
Good to Know
Installation typically involves removing the old gearbox from the A-frame mount and bolting in the replacement. Keep some grease handy to lubricate the rack gear after installation—it’ll keep everything running smooth and extend the life of your new gearbox. A quick shot of grease every few months keeps everything working like it should.
