Crown 6SR Series – 6 cu ft Mortar Mixer (Steel Drum, Highway Towable): Complete Buyer’s Guide

If you’re looking to invest in a reliable, job-site-ready mortar mixer, the Crown 6SR Series – 6 Cubic Feet Mortar Mixer with a steel drum and highway towable design should be at the top of your consideration list. Built for contractors, masons, and rental companies, this model blends portability, rugged construction, and efficient performance.

What Makes the Crown 6SR Series Stand Out?

Compact Yet Powerful Mix Capacity

With a 6 cubic foot drum, the Crown 6SR can handle up to 2–2.5 bags (around 88 lbs) of pre-mix material per batch—ideal for mortar, grout, or stucco. 

Highway-Towable for On-the-Go Jobs

Equipped with large 5.3 × 12″ pneumatic tires, high-speed taper roller bearings, and heavy-duty axles, this mixer is designed for smooth, stable towing over roads and between worksites. 

Size and Mobility That Fits Tight Jobsites

• Width: 45″ — ideal for squeezing through narrow pathways

• Height: 55″

• Tow Pole Length: Collapses to 75″ or extends to 94.5″
  These compact dimensions make setup easier, transport smoother, and overall operation more efficient. 

Engine & Gearbox Options

Versatile Power Options

You can choose from:

• Gas-powered: 5.5 HP Honda GX160 or Kohler engines

• Electric: 1.5 HP Baldor motor
  This allows flexibility depending on jobsite access to power or need for portability. 

Built for Torque, Built for Safety

The mixer features Crown’s exclusive gearbox design, which boosts paddle torque and removes the need for a heavy 6:1 reduction on the engine. Best of all, it's fully enclosed, keeping gears safe from dust and debris exposure. 

Operator-Friendly Features

Knee-Operated Drum Lock

A convenient knee-lever locks the drum in place, allowing hands-free control during dumping—making your workflow safer and more efficient.

Optional Spiral Blade Upgrade

For smoother, faster mixes, you can add spiral paddle blades—a significant upgrade over standard paddle mixers. 

Enhanced Safety Grille

Crown reinforces safety with a two-piece grill—stronger than single-piece guards—ensuring operator protection during loading and mixing.
