Stihl Gas Pole Saw Review: Pro Tips for Efficient Tree Pruning

Pole saws, in general, are incredibly useful for reaching high branches without the need for ladders, but gas-powered models offer a distinct advantage in terms of power and portability. This review will focus specifically on Stihl gas pole saws, as they are a brand I’ve consistently found to be reliable and durable through the years, but the principles discussed can often be applied to other brands as well. I have used the Stihl HT 133, HT 135 and HT 56 C-E models.

Understanding Your Needs: Choosing the Right Stihl Pole Saw

Before diving into specific models, let’s consider what makes a pole saw suitable for your needs. The right choice depends on the types of trees you typically prune, the branch diameters you encounter, and the frequency of use. I have pruned a variety of trees, from delicate fruit trees to mature oaks.

Key Factors to Consider:

• Engine Size & Power: Larger engines (measured in cubic centimeters or cc) provide more power for cutting thicker branches. The Stihl HT 135 has a more powerful engine than the HT 56 C-E. I found that the HT 135 easily tackled branches up to 8 inches in diameter, while the HT 56 C-E was better suited for branches under 6 inches.
• Cutting Length: A longer cutting bar allows you to cut larger branches in a single pass. Pole saws typically have bar lengths ranging from 10 to 14 inches.
• Weight & Balance: Pole saws can become heavy quickly, especially when extended. A well-balanced saw reduces fatigue and improves control. The distribution of weight is crucial; a top-heavy saw is more difficult to manage.
• Shaft Length & Adjustability: The length of the pole determines your reach. Adjustable shafts provide versatility for different tree heights. I prefer models with telescopic shafts that allow me to adjust the length as needed.
• Starting System: Stihl’s Easy2Start system is a game-changer, especially for those who find traditional pull starts difficult. This system reduces the effort required to start the engine.
• Anti-Vibration System: Prolonged use of a pole saw can lead to fatigue and even injury. An effective anti-vibration system minimizes the impact on your hands and arms.
• Fuel Efficiency: Gas pole saws are known for their power, but fuel efficiency is still important. Stihl’s 4-MIX engine is designed to be both powerful and fuel-efficient.
• Maintenance: Regular maintenance is essential for keeping your pole saw in top condition. Consider the ease of accessing and replacing parts, such as the air filter and spark plug.
• Price: Pole saws range in price from a few hundred to over a thousand dollars. Consider your budget and the features you need.

Data Points & Statistics:

• Engine Displacement: Stihl pole saws range from approximately 21.4 cc (HT 56 C-E) to 36.3 cc (HT 135).
• Weight: The weight of a Stihl pole saw can vary from around 12 lbs to over 17 lbs, depending on the model and shaft configuration.
• Cutting Bar Length: Stihl offers bar lengths from 10 to 14 inches on their pole saws.
• Shaft Length: Some Stihl pole saws offer a fixed shaft length around 9 feet, while others have adjustable lengths extending to 12 or 13 feet.
• Fuel Tank Capacity: Fuel tank capacity typically ranges from 17 oz to 24 oz.

My Experience:

When I first started using pole saws, I underestimated the importance of weight and balance. I purchased a model with a powerful engine but a poor weight distribution, and I quickly regretted it. After a few hours of pruning, my arms and shoulders were aching, and my control over the saw was compromised. I learned the hard way that a lighter, well-balanced saw is worth the investment.

The National Institute for Occupational Safety and Health (NIOSH) recommends wearing hearing protection when operating power equipment that produces noise levels above 85 decibels. Chainsaws and pole saws typically produce noise levels between 100 and 115 decibels.

My Experience:

I learned the importance of safety gear the hard way. I was pruning a tree without wearing safety glasses, and a small wood chip flew into my eye. It was a painful experience that could have been avoided with proper eye protection. Now, I never use a pole saw without wearing a helmet, safety glasses, hearing protection, gloves, and long sleeves and pants.

Pruning Techniques: Achieving Clean and Healthy Cuts

Proper pruning techniques are essential for maintaining the health and appearance of your trees.

Basic Pruning Principles:

• Remove Dead, Damaged, or Diseased Branches: These branches can harbor pests and diseases and should be removed promptly.
• Thin Out Crowded Branches: Thinning out crowded branches allows more sunlight and air to reach the inner parts of the tree, promoting healthy growth.
• Shape the Tree: Pruning can be used to shape the tree and improve its overall appearance.
• Maintain a Strong Structure: Prune to create a strong, balanced structure that can withstand wind and snow.
• Encourage Fruit Production: Pruning can encourage fruit production in fruit trees.

Pruning Cuts:

• Thinning Cuts: Thinning cuts remove entire branches at their point of origin. These cuts are used to thin out crowded branches and improve air circulation.
• Heading Cuts: Heading cuts shorten branches back to a bud or side branch. These cuts are used to shape the tree and encourage new growth.
• Reduction Cuts: Reduction cuts reduce the size of a branch by cutting it back to a larger lateral branch. These cuts are used to reduce the overall size of the tree without sacrificing its natural shape.

Best Practices:

• Make Clean Cuts: Use a sharp blade and make clean, precise cuts. Ragged cuts can attract pests and diseases.
• Cut at the Branch Collar: When removing a branch, cut just outside the branch collar, the swollen area at the base of the branch. Avoid cutting into the branch collar, as this can damage the tree’s vascular system.
• Avoid Topping: Topping is the practice of cutting off the top of a tree, leaving a stub. Topping is harmful to trees and should be avoided.
• Prune at the Right Time of Year: The best time to prune most trees is in late winter or early spring, before new growth begins. However, some trees, such as flowering trees, should be pruned after they bloom.

Data Points & Statistics:

• Branch Collar: The branch collar contains specialized cells that help the tree heal after pruning. Cutting into the branch collar can disrupt this process and increase the risk of disease.
• Topping: Topping can weaken trees, making them more susceptible to pests, diseases, and wind damage. Topping also creates unsightly stubs that are slow to heal.

My Experience:

I once topped a tree in my early days of pruning, thinking it would make it easier to manage. I quickly realized that I had made a mistake. The tree became weak and unsightly, and it eventually died. I learned that topping is never a good idea and that proper pruning techniques are essential for maintaining the health and appearance of trees.
