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.

Cab Comfort: The Battle of Ergonomics

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: Who Wins The Efficiency Race?

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: How To Keep These Machines Running

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.
