John Deere CM72B Large Cement Mixer

Care & Maintenance

• Pre-wet the drum with water and coarse aggregate before first use and after any idle period — concrete bonds permanently to a dry drum and is nearly impossible to remove once cured
• Flush the drum with water and a handful of gravel immediately after every pour — even 30 minutes of delay can start the curing process on residual concrete
• Grease drum bearing mounts and hydraulic motor drive shaft weekly during active use
• Inspect the drum opening seal for wear and replace before it allows concrete to reach the bearing housing — concrete in the bearing is immediate bearing failure
• Store with the drum oriented to drain — standing water inside the drum rusts the interior and degrades the mixing fins over time
