Description
When you’re maneuvering a heavy trailer around the yard or trying to line up with the hitch, that little caster wheel on your jack makes all the difference. A worn or broken caster wheel turns what should be an easy job into a wrestling match with a stubborn trailer. This replacement caster assembly gets your trailer rolling smooth again and saves your back in the process.
What You’re Getting
- Durable poly wheel that rolls easy and won’t go flat like pneumatic wheels
- Direct bolt-on replacement for Bulldog 150 Series jacks—no modifications needed
- Built to handle the weight of loaded trailers up to 5,000 pounds
- Weather-resistant construction that holds up to outdoor storage
Built for Real Farm Work
This caster works with all Bulldog jacks rated for up to 5,000 pounds, which covers most farm trailers, equipment trailers, and utility trailers you’ll find around the place. Whether you’re moving a seed tender, hay wagon, or disk around the farmyard, this wheel handles the job.
Made to Last
The poly wheel won’t crack in cold weather or get soft in the summer heat like some cheaper wheels do. It’s designed to roll over gravel, concrete, and rough ground without falling apart. The bearing assembly is sealed to keep dirt and moisture out, so it keeps rolling smooth season after season.
Installation Notes
Installation is straightforward—just remove the old wheel assembly and bolt this one in its place. Keep a little grease on the pivot points where the caster swivels, and it’ll turn easy when you need to move the trailer.
