How to Unseize a Pruning Lopper: Complete Guide to Fixing Stuck Tools

Ever tried to prune your garden, only to find your pruning lopper stuck and refusing to budge? Frustrating, right? It’s like having a tool that’s supposed to make your life easier, but it ends up causing more trouble. Don’t worry, we’ve all been there.

Common Reasons for a Pruning Lopper to Seize

Have you ever found yourself struggling with a pruning lopper that just won’t cooperate? Here are some common reasons why your trusty tool might seize up on you:

  • Rust build-up: When you neglect to clean and oil your pruning lopper regularly, rust can start to form on the blades, causing them to stick together.
  • Sap accumulation: Cutting sticky or sappy branches can leave residue on the blades over time, leading to a gummy build-up that hinders movement.
  • Debris jamming: Bits of wood, leaves, or other garden debris can get lodged in the cutting mechanism, preventing smooth operation.
  • Blade misalignment: If the blades are not properly aligned, they can rub against each other instead of cleanly cutting through branches.
  • Wear and tear: Over time, the cutting edges of the lopper can dull or become damaged, making it harder to make clean cuts and increasing the risk of seizing.
  • Lack of maintenance: Regular maintenance is key to keeping your pruning lopper in top condition. Neglecting this can lead to various issues, including seizing.
