John Deere Maintenance Monday: Choosing grease
Living the Country Life Radio Program with Betsy Freese
Radio interview source: Dick Parish, professor of agricultural engineering, LSU Ag Center
In this edition of Maintenance Monday, we're answering a question from Kevin in Texas. He just bought a used utility tractor and needs to take care of some general lubing. He's wondering how to choose the best grease for the job.
Dick Parish with the Louisiana State University Ag Center says pay attention to the viscosity rating. Low viscosity greases are needed for high-speed applications to enhance flow. High viscosity is better for slow-moving components. The thickness of grease is determined on a scale of 0-0-0 to six, with 0-0-0 being heavy oil and six a brick grease.
For a good, all-purpose grease, Parish recommends number two.
"This refers to the viscosity of the grease," Parish says. "Number 2 is a good general purpose viscosity that's used a lot for wheel bearings, chassis lubricants, bearings, this type of thing. And we also have classifications on performance levels. A typical recommendation for small tractors, lawn and garden equipment, would be a number 2 grease, rated GC-LB."
That means for wheel bearings it's rated for severe duty, and for chassis it's rated for moderate duty.
