Description
Foundation contractors battle aggregate segregation and slow drum dumping when pouring small footings. The Bartell Morrison MC95SH240 Concrete Mixer spins a nine-point-five cubic foot drum powered by an industrial Honda GX240 engine. Crews blend structural concrete with gravel aggregate on site. Manual drum dumping requires two hands on the hand wheel during stiff slump discharges.
Heavy welded steel plate forms the 9.5-cubic-foot drum with replaceable internal mixing blades to lift and fold heavy stone aggregate. A Honda GX240 four-stroke engine produces 7.9 net horsepower with splash lubrication. A cast-iron ring gear and steel pinion route power to the drum trunnion. The towable frame features high-speed highway tires and a retractable tow tongue. Machine weight is 865 lbs with dimensions of 51 inches wide by 82 inches long by 58 inches high.
Key Features of Bartell Morrison MC95SH240
Concrete flatwork crews buy Bartell Morrison MC95SH240 units when commercial concrete mixer pricing requires high yardage durability. This mixer pours footing concrete, sidewalk pads, fence post bases, and structural piers.
- Nine-point-five cubic foot drum mixes six cubic feet of wet aggregate concrete per batch.
- Honda GX240 gas engine delivers 7.9 horsepower for continuous mixing on remote jobsites.
- Heavy cast-iron ring gear withstands abrasive gravel contact without tooth shear.
- Steel mixing blades lift aggregate to eliminate dead unmixed zones at the drum bottom.
- Multi-position tilt wheel allows controlled pours into wheelbarrows or foundation forms.
- Highway-rated axle suspension protects drivetrain components during high-speed transit behind work trucks.
- Protective steel engine cowl shields the motor from aggregate splatter and water hose washdown.
Drum Ring Gear Bench Diagnostics
Tachometers verify drum rotation holds steady at 24 RPM under a full 800-pound wet gravel load. Backlash between the cast-iron ring gear and the drive pinion measures 0.025 inches on cold bench setup. Engine RPM drops by 115 RPM when operators charge dry coarse aggregate into the wet slurry. Ring gear tooth temperatures stabilize at 135 degrees Fahrenheit after two hours of continuous churning. Trunnion roller bearings maintain true alignment with zero play under maximum eccentric weight.
Field Usability Daily Maintenance Rules
The hand wheel gear drive gives single workers smooth leverage when tipping wet concrete into narrow wheelbarrow tubs. The wide tire stance prevents tip-overs across muddy jobsite ruts. Do not buy this machine for fine plaster or lime mortar work requiring tight-tolerance rubber paddle wipers.
- Apply open gear grease to the drum ring gear teeth each work week.
- Wash aggregate build-up from internal mixing blades right after the final pour.
- Check trailer wheel bearings for grease pack condition prior to highway towing.
