Bypass loppers FELCO 21, 630 mm, 35 mm capacity

Bypass loppers with 630 mm forged aluminium handles cut branches up to 35 mm in diameter. The hardened steel blade is heat-treated for lasting sharpness. A toothed counter-blade grips branches securely during each cut. The straight cutting head allows close approach to stems and tight spaces.

Two-handed operation multiplies cutting force while reducing user effort. Forged aluminium construction resists bending under heavy loads. The manufacturer backs the handles with a lifetime warranty. Rubber shock absorbers cushion impact at the end of each stroke.

Design and construction of bypass loppers 630 mm

Forged aluminium handles

Forged aluminium alloy provides high strength at low weight. The handles resist deformation during repeated heavy cuts. A non-slip coating covers the grips to prevent hand slippage. The coating contains no phthalates for safer handling.

• Material: forged aluminium alloy
• Total length: 630 mm
• Handle warranty: lifetime
• Grip coating: non-slip, phthalate-free

Red-coloured handles improve visibility in foliage and grass. The colour helps users locate the tool quickly after setting it down. Forged construction eliminates weak points found in welded or bolted joints.

Hardened steel blade assembly

The cutting blade is made from high-carbon steel hardened through proprietary heat treatment. A straight profile permits access into narrow branch forks. The toothed counter-blade holds stems firmly against the cutting edge.

• Blade material: hardened high-carbon steel
• Cutting head profile: straight
• Counter-blade: toothed design
• Maximum cutting diameter: 35 mm

A plastic groove on the blade surface prevents sap adhesion. This feature maintains cutting efficiency in resinous species. The blade can be replaced without special tools when worn.

Shock absorption and adjustment

Rubber shock absorbers sit between the handles near the pivot. They cushion the impact when handles meet after each cut. This reduces vibration transmitted to the user's hands and wrists.

• Shock absorber material: rubber
• Adjustment mechanism: bolt and nut at pivot
• Blade-to-counter-blade clearance: adjustable

An adjustment key allows users to tighten the pivot bolt when blade clearance increases. Proper adjustment ensures the blade contacts the counter-blade for clean cuts. The mechanism is accessible without disassembly.

Common applications

These loppers suit orchards, vineyards, and ornamental tree maintenance where branches exceed hand-pruner capacity. Forestry workers use them for thinning and shaping young stands. Landscapers rely on the tool for shrub renovation and hedge reduction. The 630 mm length provides reach into dense canopies without a ladder.

Replacement parts and maintenance

The manufacturer supplies individual components to extend tool life. Blade, counter-blade, shock absorbers, bolts, and adjustment key are available separately. Part 2-16 is the toothed counter-blade. Part 2-30 is the adjustment key. Part 20-11 is the spring. Part 20-10 is the shock absorber set.

• Blade replacement: part 20-1
• Counter-blade: part 2-16
• Adjustment key: part 2-30
• Shock absorber set: part 20-10
• Spring: part 20-11
• Bolt: part 20-8
• Nut: part 20-7
• Rivet: part 20-5
• Screw for counter-blade: part 20-11
• Handle assembly: parts 20-1, 20-2, 20-10, 20-5

Replace the blade when it no longer crosses the counter-blade or when damage is severe. Tighten the pivot nut to restore blade-to-counter-blade contact. Clean sap residue with solvent after each use. Store in a dry location to prevent corrosion.

Technical data

The tool weighs 1.13 kg and measures 630 mm from handle tip to handle tip. Cutting capacity reaches 35 mm diameter on green wood. The bypass mechanism delivers cleaner cuts than anvil designs. Manufactured in Switzerland using renewable energy sources.
