Reese 1400300303 Pro Series Bolt-On Jack , Black

What It Is

The Reese 1400300303 Pro Series Bolt-On Jack is a heavy-duty trailer jack designed for bolting onto the tongue of trailers, including lawn mower trailers, utility trailers, and boat trailers. It provides stable, crank-up support for leveling and parking.

Fitment & Compatibility

• Mounting: Requires a flat, horizontal mounting surface on the trailer tongue (typically 2-4 inches wide). Bolts are included, but you’ll need a drill and wrench for installation.
• Weight Capacity: Rated for up to 3,500 lbs gross trailer weight (GTW) – suitable for most single-axle lawn mower trailers carrying zero-turn mowers or garden tractors up to ~1,500 lbs.
• Trailer Type: Works with most standard A-frame or straight tongue trailers. Not for use on trailers with pre-welded jack brackets unless the bolt pattern matches (check hole spacing: ~3.5 inches center-to-center).
• OEM vs Aftermarket: This is an aftermarket replacement/upgrade. It fits many brands (e.g., Carry-On, Big Tex, Sure-Trac) but verify your trailer’s tongue width and bolt hole pattern before buying.
• Measurement Check: The jack’s drop length (distance from mount to ground) is adjustable, but ensure your trailer’s tongue height allows the jack to reach the ground when parked (measure from mount to ground).

Key Things to Know

• Installation Difficulty: Easy – typically under 20 minutes with basic tools (drill, 7/16" wrench, tape measure). No welding required.
• Durability: All-steel construction with a black powder-coat finish resists rust, but check for burrs on bolt holes that may scratch paint during install.
• Crank Handle: The included handle is removable and stores on the jack body. Some users find it stiff at first, but it loosens with use.
• Common Gotcha: The bolt holes may not align perfectly with older or non-standard trailers. Pre-drill mounting holes carefully to avoid stripping threads.

Should You Buy It

Buy this if you need a reliable, bolt-on jack for a lawn mower trailer (or small utility trailer) and want a straightforward upgrade without welding. It’s a solid value at this price, backed by strong reviews, but skip it if you have a very narrow tongue (under 2 inches) or need a top-wind model for tight spaces.
