Choosing a Flail Mower for a Mid-Size Excavator
#1
Balancing Cost, Compatibility, and Durability
When selecting a flail mower for a compact or mid-size excavator like the Takeuchi TB260, operators must weigh several factors: hydraulic flow compatibility, structural integrity, ease of installation, and long-term reliability. The TB260, with an operating weight of 12,700 lbs and an auxiliary hydraulic flow of 27 gallons per minute, can support a wide range of mower heads, but not all units are created equal.
Three brands frequently considered include:
  • Agrotok: Priced around $2,200, manufactured in China, requires a case drain. While affordable, users report mixed results. Structural flexing near the hydraulic motor mount and inconsistent weld quality are common concerns. Reinforcement of weak points—especially belt tension brackets—is recommended before use.
  • Lipa: Italian-made, priced between $6,000–$7,000, does not require a case drain. Known for solid construction and smooth operation. One unit ran 200–300 hours on a Cat 304 without issues. Ideal for users seeking reliability without exceeding mid-range budgets.
  • USA Mowers: American-built, priced around $15,000. High-end components and robust support, but often considered overkill for non-commercial or light-duty applications.
Understanding Case Drain Requirements
A case drain is a low-pressure return line that allows excess hydraulic fluid and pressure to escape from the motor housing. Some flail mowers—especially those with gear-type or piston motors—require this to prevent seal damage and overheating. Installing a case drain involves routing a hose along the boom and tapping into an unused port on the hydraulic tank. The cost is modest, and the process is straightforward for experienced technicians.
One operator successfully added a case drain to a TB175 using surplus center components rated at 3,000 psi, noting that the hose cost was minimal and installation took less than a day.
Performance and Field Feedback
Operators report that flail mowers are slower than skid steer-mounted mulchers but offer better control on steep grades and tighter spaces. A Rockhound Defender FX26, for example, performed well on a TB370 (15,000 lbs) and was stable even on uneven terrain. Though the TB260 is lighter, it can still handle similar attachments with care.
Chinese-made units may require bolt replacement before use. One user found several bolts finger-tight and replaced critical fasteners—especially motor mounts—with higher-grade hardware. Welding quality varies, and some balancing weights on the drum may need rework.
Maintenance and Pre-Use Inspection
Before first use:
  • Tighten all bolts, especially those securing the motor and drum
  • Inspect welds for cracks or poor penetration
  • Check belt alignment and tension
  • Reinforce motor mount plate if flexing is observed
  • Balance the drum if vibration occurs during spin-up
These steps can extend the life of budget units and prevent early failure. For high-end mowers, follow manufacturer service intervals and use OEM parts.
Conclusion
Choosing a flail mower for a TB260 or similar excavator involves trade-offs. Budget units like Agrotok can work with proper reinforcement and inspection, while mid-tier options like Lipa offer plug-and-play reliability. High-end models deliver premium performance but may exceed the needs of small farms or private landowners. With proper setup—including case drain installation and bolt upgrades—operators can achieve effective vegetation control without overspending.
