41″ Cut Field & Brush Flail Mower FH-EF105
The FH-EF105 is designed for tractors within 16-45 HP range and supports a 3-point Category I hitch. Key features include reversible “Y” blades for precise overlap and a 3-point connection with two right-offset positions, enabling efficient field clearing and adaptable cutting angles. This unit is not a standalone mower; it requires a compatible tractor to operate.
WooFog 7 mm Brush Hog Blades
These replacement blades are crafted from AR400 high-carbon steel, offering substantial hardness and wear resistance for tough brush and weed cutting. The blades are designed for broad applicability across common skid steer and brush cutter configurations, delivering a sharp cutting edge to achieve clean, efficient passes through overgrowth.
Vilapow Grade 5 Shear Bolt Kit
This 5-pack of Grade 5 torque shear bolts with nyloc nuts provides reliable, vibration-resistant fasteners for bush hog and rotary cutter applications. The kit includes all necessary components (1/2″ diameter, 3-1/2″ length) to minimize downtime when a shear bolt shears during heavy cutting, helping maintain field efficiency.
VEVOR PTO Shaft Series 4
This 39″ to 55″ adjustable PTO shaft features a 1-3/8″ 6-spline tractor end and a round implement end. It is built with CE certification and uses a solid 20CrMnTi carburized steel universal joint, providing robust torque transfer and compatibility with a wide range of implements, including bush hogs and finish mowers.
VEVOR PTO Shaft Series 5
The Series 5 PTO shaft includes a slip clutch and a 1-3/8″ 6-spline ends with a telescoping tube for extended reach. With compressed lengths from 43″ to 57″ (depending on model) and torque specs suitable for heavier loads, this shaft supports reliable power transfer and flexibility for demanding brush cutter setups.
VEVOR PTO Shaft Series 4 (Different Length)
Another Series 4 option with adjustable length, this shaft provides compatibility across a range of tractors and implements with a consistent 1-3/8″ 6-spline ends. It’s designed for reliable operation in rotary cutter and finish mower tasks, offering sturdy construction and predictable performance under load.
Buying Guide: Key Considerations for Brush Hog Attachments and Parts
- Tractor compatibility: Confirm horsepower range, hitch type (Category I vs II), and PTO shaft size to ensure a safe, efficient match with your brush hog or cutters.
- Attachment vs. replacement parts: Distinguish between complete mower units (like the FH-EF105) and essential components (blades, shear bolts, PTO shafts) to address immediate needs and long-term reliability.
- Material and durability: For blades and blades sets, AR400 or similarly hardened steels offer longer service life under tough brush cutting. Consider blade geometry and mounting options for cutting efficiency.
- Safety and maintenance: Keep spare shear bolts on hand to prevent unexpected downtime. Inspect PTO shafts for wear, proper lubrication, and alignment to reduce hazards during operation.
- Length and reach: PTO shafts and driveline components must extend to accommodate your tractor-implement spacing. Adjustable-length shafts provide flexibility for different implements and working environments.
- Cost vs. uptime: While premium blades and heavy-duty shafts may cost more upfront, they can reduce downtime and maintenance costs over time, especially in demanding field conditions.
- Application scope: For grassland, pastures, and brush, a dedicated brush cutter or flail mower may offer a broader cutting capacity than standard mowing decks. Consider the terrain and typical vegetation you encounter.
- Warranty and support: Check manufacturer warranties and availability of replacement parts or blades to ensure continued performance and serviceability.
