The STIHL HT 105 petrol telescopic pole pruner is a professional long-reach machine for pruning tall trees, removing deadwood and maintaining orchards, estates, parks and municipal grounds.
Its 31.4 cm³ STIHL 4-MIX engine produces 1.05 kW / 1.4 hp, while the rigid telescopic shaft adjusts from 270 to 390 cm. This provides a working reach of up to approximately 5 metres, depending on the operator, stance and branch position.
The HT 105 is supplied with a 30 cm / 12-inch guide bar and a low-kickback 1/4″ P Picco Micro 3 chain. A lightweight magnesium gearbox, integrated branch hook and professional square-profile shaft help the operator position the cutting attachment accurately when working at extended reach.

Who is the STIHL HT 105 suitable for?
The HT 105 is designed for frequent and professional tree-maintenance work where a conventional hand pruner or domestic pole saw does not provide sufficient reach or cutting performance.
Typical applications include:
- Pruning established fruit trees
- Removing deadwood from tall trees
- Cutting suitable storm-damaged branches
- Maintaining orchards and commercial fruit-growing sites
- Estate and park tree maintenance
- Municipal and grounds-care work
- Professional landscaping and arboricultural ground operations
The HT 105 is intended for limbing and pruning. It is not designed for tree felling or for processing logs and firewood at ground level.
Professional telescopic shaft
The total machine length can be adjusted from approximately 270 to 390 cm. The shaft can be altered without tools to suit the working height or shortened for transport and storage.
Its square-profile construction provides greater torsional rigidity than a conventional round shaft. This helps reduce twisting when the shaft is extended and supports more accurate positioning of the cutting attachment.
The quoted 5-metre figure is an approximate working reach rather than the physical length of the machine. Actual reach depends on the operator’s height, stance, branch position and safe working conditions.
31.4 cm³ STIHL 4-MIX engine
The 31.4 cm³ STIHL 4-MIX engine combines four-stroke operating principles with mixture lubrication. It does not have a separate engine-oil sump and instead runs on STIHL MotoMix or a correctly prepared 50:1 petrol and two-stroke oil mixture.
The engine produces 1.05 kW / 1.4 hp and is designed to deliver useful low-speed torque for professional pruning work.
The 4-MIX design avoids some of the additional oil-circuit components found in conventional four-stroke engines, while providing a distinctive, lower-pitched operating sound.
Automatic decompression
The automatic decompression system temporarily reduces cylinder pressure during starting. This reduces the force required on the starter cord and supports a smoother starting process.
Manual fuel pump
The manual fuel-pump bulb helps draw fuel into the carburettor before starting. Pressing it several times can reduce the number of starter pulls required, particularly after a longer period of storage or after the fuel system has been emptied.
30 cm guide bar and PM3 saw chain
The current UK HT 105 is supplied with a 30 cm / 12-inch guide bar and a 1/4″ P Picco Micro 3 saw chain.
| Guide-bar length | 30 cm / 12 inches |
|---|---|
| Chain pitch | 1/4″ P |
| Chain type | STIHL Picco Micro 3 |
| Chain gauge | 1.1 mm |
The narrow-kerf chain provides clean, controlled cuts while making efficient use of the engine’s output.
Always verify the bar length, chain pitch, gauge and drive-link count shown on the fitted equipment before ordering replacement cutting parts.
Magnesium gearbox and branch hook
The compact gearbox housing is made from magnesium to reduce cutting-head weight while retaining professional durability.
A robust cast-in branch hook helps pull down loose cuttings after a branch has been severed. Lateral chip ejection also helps reduce the accumulation of sawdust and wood chips around the sprocket-cover area.
Limbing sight
The raised positioning mark on the sprocket cover helps the operator align the guide bar with the intended cut before the chain enters the branch.
This is particularly useful when the cutting attachment is several metres away from the operator.
Side-mounted chain tensioning
The chain-tensioning screw is accessed from the side of the sprocket cover. This permits controlled chain adjustment while helping keep the operator’s hands away from the sharp cutting teeth.
Switch off the engine and follow the STIHL instruction manual before inspecting or adjusting the cutting attachment.
STIHL anti-vibration system
Buffer and spring elements reduce the amount of engine vibration transmitted to the handle area. This helps improve comfort during suitable pruning work, although correct technique, task rotation and appropriate breaks remain important.
Multifunction control handle
The principal engine controls are integrated into the control handle. This allows the operator to control the engine without repeatedly moving their hand away from the normal operating position.
The machine must still be supported and guided with both hands during operation.
Fuel and chain-oil capacities
- Fuel-tank capacity: approximately 530 ml
- Chain-oil capacity: approximately 220 ml
The engine and cutting attachment use separate fluids:
- The engine requires STIHL MotoMix or a correct 50:1 petrol and two-stroke oil mixture.
- The guide bar and chain require suitable chainsaw chain oil.
The fuel and oil capacities are designed so that chain oil should not normally need to be added between tanks of fuel when the machine is correctly set up and operated.
Shoulder strap and harness compatibility
A padded shoulder strap is supplied with the HT 105. The machine also includes a mounting clamp for use with the optional STIHL RTS harness.
At 7.9 kg before the guide bar, chain, fuel and oil are added, the HT 105 is a substantial professional machine. The RTS harness is worth considering for repeated or prolonged work because it transfers more of the load to the user’s hips.

HT 105 versus HT 135
| Model | Best suited to | Main reason to choose it |
|---|---|---|
| STIHL HT 105 | Professional pruning, orchards and regular municipal or estate work | Lower purchase cost and 1.05 kW output for general professional pole pruning |
| STIHL HT 135 | More demanding professional work and larger branches | Higher engine output for intensive cutting |
Both models use a professional rigid telescopic shaft with a maximum total length of approximately 390 cm. Choose the HT 135 where higher cutting output is regularly required rather than simply fitting a more aggressive cutting attachment to the HT 105.
HT 105 or a cordless pole pruner?
The petrol HT 105 is well suited to users who require consistent refuelling, established 4-MIX equipment and long professional working periods without battery charging.
A cordless model may be preferable where lower operating noise, push-button starting, reduced routine engine maintenance and no direct exhaust emissions during use are priorities.
| Model | Best suited to |
|---|---|
| STIHL HTA 86 | Users prioritising lower weight, cordless convenience and adjustable reach |
| STIHL HTA 135 | Professional cordless work requiring high output and a rigid telescopic shaft |

Masseys recommendation
The HT 105 is a strong choice for professional users who require a petrol telescopic pole pruner but do not need the additional output and price of the HT 135.
Its key strengths are the rigid 270–390 cm shaft, professional 4-MIX engine, accurate 30 cm cutting attachment and easy refuelling during extended working days.
Its main consideration is weight. At 7.9 kg before fitting the guide bar, chain and fluids, it is considerably heavier than lighter cordless pole pruners. We recommend considering the RTS harness for regular use.
Customers mainly working in residential, school, hospital or noise-sensitive environments should also compare the HTA 86 and HTA 135 cordless models.

Safety and correct use
A pole pruner is a high-speed cutting tool with an extended working reach. Read the complete STIHL instruction manual before first use and obtain suitable practical instruction where required.
Always:
- Operate the machine with both hands
- Work from firm, stable ground
- Wear eye, head, hearing, hand and foot protection
- Keep people and animals well clear of the work area
- Assess falling branches and create a clear escape route
- Stay clear of overhead electrical cables
- Keep the chain correctly sharpened, tensioned and lubricated
- Stop the engine before inspecting or adjusting the cutting attachment
Do not stand directly beneath the branch being cut. The HT 105 is intended for pruning and limbing, not tree felling.
