Stihl HT 135 Pole Saw

STIHL HT 135 Telescopic Pole Pruner: High-Reach Professional Timber Care

The STIHL HT 135 is the undisputed heavyweight champion of professional telescopic pole pruners, custom-built for arborists, fruit growers, and estate maintenance crews needing to tackle high-altitude limbing without ever leaving the ground. Driven by STIHL’s high-torque 36.3 cc 4-MIX® engine, this unit combines four-stroke power and lower emissions with fast-accelerating two-stroke responsiveness. The rigid square-profile telescopic drive tube extends smoothly from 2.7 m to 3.9 m, allowing operators to comfortably prune branches up to 5 metres high. Featuring a ultra-lightweight magnesium transmission housing with an integrated cast-metal branch hook, the HT 135 balances top-heavy mass with surgical cutting precision—delivering maximum leverage and high-speed timber reduction while reducing physical fatigue during multi-hour forestry shifts.

• Ultra-Rigid Square Telescopic Drive Tube: Unlike round shafts that twist or bow under heavy loads, the square-section inner shaft delivers maximum torsional rigidity and precise directional control when maneuvering high up in dense tree canopies.

• High-Torque STIHL 4-MIX® Engine Mechanics: Combines standard 50:1 petrol-oil mixture with internal 4-stroke valve timing. This eliminates oil-sump maintenance while producing 1.4 kW (1.9 HP) of unrelenting cutting power and lower operational noise.

• Magnesium Gearbox Architecture: Uses a magnesium head casing that drops weight at the furthest point of reach without sacrificing structural strength, allowing for effortless continuous working overhead.

• Integrated Cast-Metal Branch Hook: Built directly onto the magnesium gear housing, the heavy-duty hook allows you to quickly pull down trapped, freshly cut limb debris from the canopy without damaging surrounding wood.

• Lateral Chip Ejection & Sprocket Sight-Line: Includes a specialized side-discharge guard to prevent clogging from sticky sap and damp wood shavings, while the built-in directional line on the sprocket cover aids precise positioning.

• Equal 1:1 Tank Consumption Ratio: Engine and chain-oil capacities are calibrated so fuel and bar lubricant run down simultaneously, eliminating unnecessary stops mid-job to check chain oil levels.

• Tool-Free Quick Adjustment Mechanism: Allows the operator to alter the total tool length from 270 cm to 390 cm with a quarter-turn clamp, ensuring rapid deployment and effortless transport.
