Forestry is one of the most demanding industries in the world. It requires machines that can stand up to harsh conditions, survive daily abuse, and operate efficiently while being comfortable enough for operators to use for hours on end.
The feller bunchers are essential machines in this industry, designed to cut down trees and gather them into piles for removal. In this article, we will compare two of the most popular feller bunchers: The Tigercat 720E and John Deere’s 643L-II.
For those not familiar with forestry machines, a feller buncher is a tracked or wheeled vehicle that cuts down trees and collects them in a pile. The machine has a cutting head with saws or shears mounted on hydraulic arms that can cut down trees ranging from small saplings to large mature ones. Once cut, the arm gathers multiple trees together and holds them tightly until they are released in a pile for removal.
Feller bunchers come in different sizes, models, and brands; each with unique features that make them suitable for specific tasks. They are used primarily in industrial logging operations but can be found on smaller farms where woodlands need clearing.
The reason we are comparing these two machines is because they represent some of the best technology available today from their respective manufacturers. Both have unique features that make them stand out among their competitors. The Tigercat 720E was introduced into the market back in 2008 as an improvement over previous Tigercat models.
It has a powerful engine, a durable chassis, and enhanced hydraulics that allow it to cut through trees with ease. The Deere 643L-II is the latest model from John Deere’s feller buncher lineup.
It boasts of advanced electronics, improved operator controls, and better fuel economy. By comparing these two machines side by side, we can gain insight into what makes them unique and determine which one would be the best fit for specific forestry operations.
When it comes to feller bunchers, the Tigercat 720E and Deere 643L-II are two of the most popular models in the market. The Tigercat 720E was released in 2008 and has since gained a reputation for its durability, efficiency, and reliability. On the other hand, the Deere 643L-II is a newer model that boasts advanced technology features that make it one of the most modern feller bunchers in its class.
One of the key differences between these two machines is their horsepower. The Tigercat has a Cummins QSB6.7 engine that delivers up to 216 horsepower while Deere’s PowerTech PSS engine can deliver up to 243 horsepower. The weight also differs significantly with the Tigercat weighing around 44,000 lbs while the Deere weighs almost half at around 25,000 lbs making it more maneuverable.
When it comes to cutting capacity – an important factor for any feller buncher – both machines are capable of handling large trees efficiently. The Tigercat can cut trees as large as thirty inches in diameter with its high-performance head while Deere’s cutting head offers a maximum capacity of twenty-two inches in diameter.
It’s worth noting that each machine has been designed with different job requirements in mind; therefore, they excel at different tasks. For example: The Tigercat is perfect for forestry work thanks to its robust design which allows it to tackle tough terrain easily; however on flat surfaces or where speed is more important than stability or durability then Deere will be better suited due to being lighter and faster mainly due to its wheeled design.
When it comes to operating heavy machinery, comfort matters. After all, the operator needs to remain focused on the task at hand and not distracted by discomfort, awkward control placement, or poor visibility. In comparing the Tigercat 720E and Deere 643L-II feller bunchers, it’s clear that both manufacturers have prioritized cab comfort in their designs.
The Tigercat 720E boasts an ergonomic design that allows for maximum operator comfort during long work hours. The controls are conveniently placed within reach and easy to use.
Visibility is also a strong point with the large windows providing excellent views of the cutting area. On the other hand, Deere has also done an excellent job with their cab design for the 643L-II feller buncher.
Like its competitor, this machine offers great visibility with its large windows. However, what really sets it apart is how spacious the cab feels due to its high roofline and well-placed controls.
Fuel efficiency is a critical factor when operating any heavy machinery since fuel costs can quickly add up over time. In comparing these two machines’ fuel efficiency levels, there are distinct differences between them.
The Tigercat 720E operates with a fuel-efficient Tier II engine technology that meets emissions standards while minimizing fuel consumption. That being said, it’s important to note that this technology may not be as advanced as some other models released ten years later.
The Deere 643L-II takes advantage of modern engineering by incorporating advanced technologies such as Final Tier IV compliant engines and Electric over Hydraulic Controls (EOHC). This innovative system eliminates hydraulic leaks while reducing fuel consumption significantly compared to other systems on older machines.
Maintenance requirements for heavy machinery can be quite extensive and vary greatly depending on the specific model. For those considering purchasing a Tigercat 720E or Deere 643L-II, it’s important to understand what maintenance is required for each machine.
The Tigercat 720E requires regular oil changes, fuel filter replacements, air filter replacements, and occasional hydraulic fluid changes. Additionally, it’s recommended that certain components are inspected regularly for wear and damage.
Similarly, the Deere 643L-Il requires regular maintenance such as oil changes, air filter replacements and inspections of the machine’s hydraulic system – which is essential to maintain peak performance levels. While neither machine is particularly difficult to maintain given their relatively simple designs, it’s clear that Deere has made efforts toward ease of maintenance with features like easily accessible ports for fluid checks and routine service points located in one convenient location.
Overall, both machines have their strengths when it comes to cab comfort, fuel efficiency and maintenance requirements. It is up to the operator to decide which feller buncher best suits their specific needs based on these key factors.
When it comes to noise level, the Tigercat 720E and Deere 643L-II are both relatively quiet. The Tigercat has a decibel level of around 76 dB, while the Deere comes in slightly louder at around 80 dB.
It’s important to note that these decibel levels can vary based on a number of factors, such as terrain and how hard the machine is working. One thing that sets the Tigercat apart from the Deere is its muffler design.
The Tigercat features a pivoting muffler that can be adjusted to direct exhaust away from the operator and other workers on site. This not only reduces noise pollution but also improves air quality.
When it comes to turning radius, both feller bunchers have impressive maneuverability. The Tigercat has a turning radius of approximately 17 feet (5 meters), while the Deere can turn in just over 19 feet (6 meters).
However, it’s worth noting that turning radius alone doesn’t necessarily translate into better performance out in the field. Other factors such as ground conditions and operator skill also come into play.
Ground pressure is an important consideration for any heavy equipment operating in forestry or other sensitive environments. In this regard, both machines perform admirably. The Tigercat features wide tires and a low center of gravity which distribute weight evenly across soft terrain.
This results in very minimal ground disturbance with around 4 psi of ground pressure. Likewise, the Deere boasts similar capabilities with its large wheels and evenly distributed weight resulting in just over 5 psi of ground pressure – making it ideal for working on softer soils.
Overall, both machines are highly capable and efficient feller bunchers, with each having its own strengths and weaknesses. When it comes to choosing between the Tigercat 720E and Deere 643L-II, it’s important to consider the specific needs of your operation and which features will be most important for your particular job site.
The 2008 Tigercat 720E Feller Buncher and the 2019 Deere 643L-II Wheeled Feller Buncher are both excellent machines with their own strengths and weaknesses. The Tigercat has more horsepower, a larger cutting capacity, and is more maneuverable due to its tracked design. On the other hand, the Deere has a more comfortable cab, is more fuel-efficient, and exerts less ground pressure due to its wheeled design.
Ultimately, the decision between these two machines will depend on the specific needs of your job site. If you need maximum power and maneuverability in rough terrain with minimal ground damage, then the Tigercat may be your best option.
However, if comfort and fuel efficiency are high priorities for your operation or if you frequently work on softer soil that requires less ground pressure, then the Deere may be a better choice. It’s important to evaluate all factors before making your decision.
Consider what features are most important for your operation and seek guidance from industry experts or experienced operators if needed. With careful consideration and evaluation of these factors, you can select the feller buncher that best fits your needs and helps you achieve success in your logging operations!
