Choosing the Right Rotary Cutter for Bobcat T190 with High Flow

[MikePhua]

Introduction
When working with skid steers and other heavy equipment, one of the most versatile attachments you can use is a rotary cutter, also known as a brush cutter. This tool is especially useful for clearing brush, small trees, and other vegetation quickly and efficiently. For machines like the Bobcat T190, a high-flow auxiliary hydraulic system can provide the power necessary to operate heavy-duty rotary cutters. However, choosing the right rotary cutter for your T190 with high-flow hydraulics is crucial for ensuring optimal performance, preventing damage, and extending the lifespan of both the machine and the attachment.
This article will dive into key considerations when selecting a rotary cutter, how high-flow hydraulics impact performance, and offer some expert tips for ensuring you get the best results from your equipment.
Understanding High-Flow Hydraulics on the Bobcat T190
The Bobcat T190 skid steer loader is equipped with an optional high-flow auxiliary hydraulic system that allows the machine to power attachments requiring more hydraulic pressure, such as rotary cutters. The high-flow option provides increased hydraulic flow rates, which enhances the machine's ability to operate hydraulic tools efficiently. The standard flow rate on the T190 is around 16-20 GPM (gallons per minute), but with the high-flow option, it can go up to 26-30 GPM.
This high-flow system is crucial for heavy-duty tasks, such as running large rotary cutters, as these attachments require a higher volume of hydraulic fluid to operate their motors at full capacity. Without sufficient flow, the cutter may underperform, struggle with cutting, or even cause damage to the hydraulic components of both the attachment and the machine.
Factors to Consider When Choosing a Rotary Cutter for High Flow

1. Flow Rate Compatibility
   The first thing to check when choosing a rotary cutter is whether the attachment is designed to work with high-flow hydraulics. Many rotary cutters are available in different sizes, and each type has specific hydraulic flow requirements. You should look for cutters designed to handle flow rates that match or are slightly above the maximum high-flow capacity of your T190 (usually 26-30 GPM). Choosing an attachment with a hydraulic flow rate that exceeds this value could lead to unnecessary wear on the machine’s hydraulic system, while a cutter designed for lower flow rates may not perform optimally.
   
2. Cutting Capacity
   Rotary cutters come in various sizes, ranging from small 36-inch models for lighter work to larger 72-inch cutters for more intensive clearing tasks. The cutting capacity of the rotary cutter should be aligned with the expected workload. For the T190, you will want to choose a cutter that provides a good balance between size and power. Larger cutters are generally better suited for handling thick brush and small trees, but they may require more flow and can reduce maneuverability.
   
3. Blade Type and Durability
   The blades of a rotary cutter are essential for its cutting performance. There are various types of blades available, including stump jumpers, Y-shaped blades, and heavy-duty flail blades. Stump jumpers are ideal for clearing large brush and woody vegetation, as they can “jump” over obstacles like rocks or stumps. Heavy-duty flail blades are better for cutting through thick, dense material but may require more hydraulic power to operate efficiently.
   Durability is another important factor. Rotary cutters designed for high-flow machines like the T190 should be built to handle the increased hydraulic pressure without damaging the motor or components. Look for cutters made from high-strength materials, such as hardened steel, for longer-lasting performance.
   
4. Weight and Balance
   Rotary cutters come in different weights, and it is important to ensure that the cutter you choose is compatible with the T190's lifting capacity and handling characteristics. The T190 has a rated operating capacity of approximately 1,900 lbs. Depending on the size of the rotary cutter, the weight of the attachment can significantly affect the machine’s handling, especially when working on uneven terrain. It’s important to choose a cutter that balances the machine's weight distribution to avoid putting excessive strain on the skid steer.
   
5. Maneuverability and Reach
   When using a rotary cutter, you may be required to cut in tight spaces or on rough terrain. A cutter with a longer reach or swivel capability provides greater maneuverability, allowing you to access hard-to-reach areas without repositioning the entire machine. Look for cutters that offer adjustable arms or hydraulic angles to allow more flexibility when working on uneven ground.
   
6. Safety Features
   Rotary cutters can pose safety risks, especially when dealing with dense brush or tree stumps. Choose an attachment that includes safety features such as protective covers or shields to prevent debris from flying toward the operator. Additionally, some high-flow rotary cutters come with a “soft start” feature that helps protect the motor and the hydraulic system by gradually increasing the cutting speed.
   

Recommended Rotary Cutters for Bobcat T190 High Flow
Here are some top rotary cutter models that are compatible with high-flow hydraulic systems like the one found on the Bobcat T190:

1. Bobcat 60” or 72” Rotary Cutter
   Designed for heavy-duty use, Bobcat’s own line of rotary cutters are well-suited for use with their T-series skid steers. The 60” and 72” models are great for clearing dense vegetation, including thick brush and small trees. The heavy-duty build quality ensures long-lasting performance, and the blade configuration provides consistent cutting results.

Maintenance Tips for High-Flow Rotary Cutters
To ensure that your rotary cutter continues to perform at its best, proper maintenance is key. Here are some tips to keep in mind:

1. Regularly Check Hydraulic Fluid: Ensure the hydraulic fluid is clean and at the correct level. Dirty or low hydraulic fluid can lead to inefficient operation and can wear out both the cutter and the T190’s hydraulic system.
   
2. Inspect Blades and Replace When Necessary: Blades can dull or become damaged over time. Regularly inspect the blades for chips, cracks, or excessive wear. Replace them as needed to maintain cutting efficiency.
   
3. Lubricate Moving Parts: Keep the cutter’s moving parts well-lubricated to reduce friction and wear. This will help extend the lifespan of the attachment and ensure smooth operation.
   
4. Check for Leaks: Hydraulic leaks can significantly affect performance. Inspect hoses, fittings, and seals regularly to ensure they are in good condition.
   
5. Monitor Machine Settings: Ensure that the Bobcat T190’s hydraulic system is properly set up for high-flow operation before using the rotary cutter. This includes checking the pressure and flow rates to match the cutter’s requirements.
   

Conclusion
Choosing the right rotary cutter for a Bobcat T190 with high-flow hydraulics requires careful consideration of several factors, including hydraulic compatibility, cutting capacity, weight, and safety features. By selecting the right cutter for the job and ensuring proper maintenance, you can enhance the performance of your machine, extend the life of your attachments, and ensure safer and more efficient land clearing. Always remember to check for compatibility with the T190’s high-flow system to get the most out of both the machine and the rotary cutter.
