Product Description

The Flail Mower Gearbox RDF-PK45-006 is a heavy-duty agricultural gearbox built to transfer tractor PTO power to flail mower blades at high torque and constant speed. It is a direct-fit agricultural gearbox replacement for worn or failed flail cutter gear units on flail mowers, verge mowers, brush cutters and tractor mower attachments — engineered for continuous heavy-load mowing, not for light-duty garden use.

High-Torque Output Precision-meshed gearing keeps blade speed stable under dense grass, crop residue and saplings.

Direct-Fit Replacement Mounting flange and shaft configuration matched to the original unit for fast swap-in, less downtime.

Sealed & Contamination-Proof Double lip seals and machined sealing faces keep dust, grit and moisture away from bearings and gears.

OEM / ODM Ready Custom splines, ratios, flanges, paint and your own brand on the housing and packaging.

How the RDF-PK45-006 Flail Mower Gearbox Works

The input shaft connects to the tractor PTO through a PTO drive shaft. Rotational power enters the housing and is transferred through a matched gearbox gear set, which raises torque and holds the output shaft at the speed your flail rotor needs. The output shaft drives the rotor and flails, so the blades keep cutting at high speed instead of stalling in dense vegetation.

Bearings support both shafts to reduce friction and wear; oil seals protect the internals from field debris. A torque limiter or slip clutch can be specified on the drive line to protect the gearbox from shock loads when the rotor hits stones, wire or stumps — a common cause of gearbox failure on flail mowers.

Maintenance That Extends Flail Mower Gearbox Life

Check gear oil level before each season and change it at the interval in your machine manual.
Inspect oil seals and the output shaft area for weeping — early seal replacement is far cheaper than a bearing failure.
Keep the PTO shaft angle within the recommended limit and grease the universal joints regularly.
Fit or maintain the slip clutch / torque limiter so shock loads are not passed into the gearbox.
Re-torque mounting bolts after the first 20 hours of operation, then at routine service intervals.
