Leaf loss is one of the biggest causes of quality loss in alfalfa and clover hay. Because leaves contain 70–90% of total protein, losing them means losing nutrition, value, and buyer trust.

Fortunately, most leaf loss happens due to avoidable handling issues — especially when hay is too dry, raked aggressively, or baled at the wrong moisture. Below are the most effective strategies to keep leaves where they belong: in the bale, not on the ground.

⭐ 1. Bale at the Correct Moisture (the #1 factor)

Leaf shatter dramatically increases when hay is below 12% moisture. Alfalfa and clover need to be baled slightly higher than grass hay.

Optimal baling moisture:

• Small squares: 15–18%
• Large rounds: 14–16%
• Large squares: 12–15%

If the hay feels “crispy,” it’s too dry — and leaves will fall off with every turn of the bale chamber.

⭐ 2. Rake at the Right Time (with morning dew if possible)

Raking is where the highest percentage of leaf loss occurs, especially for alfalfa.

Best practices:

• Rake during early morning dew to soften leaves
• Use gentle, slow PTO speeds
• Avoid raking when hay is brittle
• Rake only once when possible
• Form uniform windrows to prevent over-handling

Some growers even wait for a small humidity rise in the afternoon to rake safely.

⭐ 3. Widen Your Windrows at Cutting

Wide windrows allow hay to dry evenly from top to bottom.

Benefits of wide windrows:

• Faster drying → less time for leaves to become brittle
• More uniform moisture at raking
• Lower handling loss due to reduced tedding or turning

The wider the swath (70–80% of the cutter bar), the better the leaf retention later.

⭐ 4. Use Tedders Carefully (or sparingly)

Alfalfa can lose 10–20% of leaves in one aggressive tedding pass.

Use tedders only when needed and only at the right moisture levels:

• Ted early, while hay still has moisture
• Avoid tedding after stems are dry
• Use low rotor speeds
• Lift tedder teeth to minimize crop contact

If you must ted, do it within the first 6–8 hours after cutting.

⭐ 5. Adjust Baler Pickup Height Correctly

Many operators set the pickup too low, causing leaves to be beaten off before entering the chamber.

For best results:

• Raise the pickup teeth so they skim the ground without digging
• Slow pickup speed where possible
• Keep the windrow fluffy — compact windrows beat up leaves

A small adjustment can save pounds of leaves per acre.

⭐ 6. Match Bale Density to Crop Conditions

Overly tight bales crush leaves and increase shatter during handling.

Recommended approach:

• Increase density only when the crop has adequate moisture
• Use moderate density settings on dry alfalfa
• Monitor bale chamber pressure frequently

If the baler forces too much compression on brittle leaves, losses increase.

⭐ 7. Harvest Earlier in the Maturity Stage

Over-mature alfalfa and clover:

• Become stemmy
• Lose leaf-to-stem ratio
• Produce more leaves that naturally detach

Cutting earlier preserves leaf attachment strength and improves bale nutrition.

---

⭐ 8. Store and Handle Bales Gently

Leaf loss doesn’t stop after baling.

Reduce shatter by:

• Keeping bales out of direct sunlight
• Avoiding rough loader handling
• Loading trailers slowly
• Storing bales where humidity is moderate

Every dropped bale equals protein lost.

Final Thoughts

To reduce leaf loss in alfalfa or clover hay, timing is everything — timing of raking, tedding, and baling moisture. Combine gentle equipment settings with smart decision-making, and your hay will retain more nutrition, color, and value.
