Introduction
Silage pit compaction is traditionally performed using tractors or wheeled loaders, but some operators have explored the use of heavy tracked excavators for this task. A 20-ton digger, with its substantial weight and versatile movement, presents an unconventional yet potentially effective alternative. This article examines the practicality of using such machines for silage compaction, clarifies relevant terminology, and shares field-tested techniques, anecdotes, and historical context.
Understanding Silage Pit Compaction
Silage is fermented, high-moisture fodder stored in pits or bunkers and used to feed livestock. Proper compaction is critical to exclude oxygen and promote anaerobic fermentation, which preserves nutritional value and prevents spoilage.
Key goals of compaction include:

• Maximizing density to reduce air pockets
  
• Creating uniform layers for consistent fermentation
  
• Preventing runoff and seepage
  

• Silage Pit: A trench or bunker where chopped forage is stored and compacted for fermentation.
  
• Ground Pressure: The pressure exerted by a machine on the surface, influenced by weight and contact area.
  
• Point Loading: Concentrated pressure applied by wheels or tracks, affecting compaction depth.
  
• Sheepfoot Roller: A compaction tool with protrusions that penetrate and compress soil or silage layers.
  

• High Machine Weight
  Excavators in this class weigh around 40,000 lbs, offering deep compaction potential when properly applied.
  
• Controlled Movement
  The ability to walk slowly and deliberately allows for targeted compaction.
  
• Bucket Versatility
  Operators can use the bucket to push, pull, or tamp silage, especially near pit edges.
  

• Low Ground Pressure
  Wide tracks distribute weight, reducing point loading compared to wheeled machines.
  
• Limited Rolling Action
  Excavators lack the dynamic rolling compaction provided by tires.
  
• Risk of Getting Stuck
  Silage, especially when wet or made from slick crops like oats or peas, can trap heavy machines.
  

• Layer Thinly
  Apply silage in thin layers (6–8 inches) to allow effective compaction without trapping air.
  
• Use Bucket Tamping
  Lower the bucket and apply downward pressure to compress silage, especially near walls.
  
• Rear Track Loading
  Lift the front of the machine slightly using the bucket to concentrate weight on the rear tracks.
  
• Avoid Wet Conditions
  Wet silage increases the risk of machine slippage and uneven compaction.
  
• Combine Methods
  Use the excavator for edge work and layering, followed by a wheeled machine for final compaction.
  

• Monitor track slippage and avoid steep pit slopes
  
• Ensure silage is evenly distributed before compaction
  
• Maintain clear visibility and communication with ground crew
