Description
Meeting strict jobsite safety and road transit regulations demands dependable towing hardware and compliant guard cages. The Crown 6SR-GH5 Towable Mortar Mixer brings highway-compliant mobility and six cubic feet of mixing capacity to medium masonry jobs. A 5.5-HP Honda engine drives the paddles. The drum capacity restricts batches to two bags of mortar.
High-strength quarter-inch steel forms the six-cubic-foot drum shell to resist aggregate abrasion. A Honda GX160 overhead-valve gas engine delivers 4.8 net horsepower with fuel-efficient operation. Heavy-duty roller chain drives link the reduction jackshaft to the paddle assembly inside grease-sealed pillow block bearings. A leaf-spring trailer suspension supports high-speed highway travel with a pintle ring hitch. The unboxed tool weighs 660 lbs with dimensions of 47 inches wide by 76 inches long by 54 inches high.

Towing Chassis Bench Diagnostics Data
Tachometers measure drum paddle speed at 40 RPM under a full 650-pound wet mortar batch. The Honda GX160 engine maintains steady throttle speed, dropping only 110 RPM under peak mixing load. Axle alignment tests confirm straight tracking during simulated fifty-five MPH towing tests. Neoprene drum seals show zero paste leakage during sixty minutes of water slurry agitation. Drum tilt latch pins lock firmly without slipping under maximum wet load discharge angles. Drive chain tension remains stable under repeated shock loads.
Field Operation Drum Care Procedures
The compact footprint allows one worker to swing the tongue around tight residential jobsites before coupling to a pickup truck. Low load height simplifies dry sack dumping into the drum. Do not buy this mixer for massive commercial projects requiring five-bag batches or high-output pumping.
- Grease the main paddle shaft bearings every week through grease fittings.
- Wash down the drum interior with hose water right after pouring the last batch.
- Check trailer tire pressure and lug nut tightness before towing on highways.
