Gleaner M3 Combine Parts

Jump to Parts

The Gleaner M3 combine, produced from the mid-1970s to the early 1980s, became a favorite among farmers due to its efficient harvesting capabilities and durable design. Powered by engines ranging from 165 to 185 HP, it offered header widths up to 24 feet, accommodating various field sizes. This combine utilized a conventional cylinder separator, known for its effective threshing and separation of grain.

The Gleaner M3 was a workhorse in the Gleaner lineup, produced from 1976 to 1982, building upon the legacy of its predecessors. It typically featured a Cummins or a Deutz diesel engine, delivering between 165 and 185 horsepower, with displacements around 5.9 liters. The M3 employed a conventional cylinder and concave system for threshing, followed by straw walkers for separation, a design valued for its ability to handle tough crop conditions. Grain tank capacity was approximately 180 bushels, and the unloading auger could empty the tank at a rate of around 50 bushels per minute. Farmers could equip the M3 with headers ranging from 13 to 24 feet wide. Options included a chopper or spreader to manage crop residue. The cab offered basic comfort and controls for the operator. The Gleaner M3 excelled at harvesting wheat, soybeans, and corn, demonstrating its versatility across different crops.

Maintenance Tips

Concave Adjustment: Regularly inspect and adjust the concave clearance to match the crop being harvested. Proper adjustment minimizes grain loss and maximizes threshing efficiency.
Belt and Chain Tension: Check and maintain proper tension on all belts and chains to prevent slippage and ensure smooth operation of the combine's various systems.
Sieve and Chaffer Cleaning: Clean the sieves and chaffer regularly to remove debris and ensure proper air flow. This prevents grain loss and improves sample quality.
Bearing Greasing: Grease all bearings at the recommended intervals to prevent premature wear and ensure smooth, reliable operation. Consult the operator's manual for specific grease points and intervals.
