Rotary Mower Gearbox LF-227J - TEBSA’s Reliable Replacement for Comer Code LF-227J

When it comes to keeping your rotary mower in top shape, the gearbox is the unsung hero that powers those spinning blades through grass, weeds, and tough vegetation. At TEBSA, the Argentine branch of HZPT, we’re proud to offer the Rotary Mower Gearbox LF-227J—a durable, high-performance replacement for the Comer Code LF-227J. Built for agricultural machinery, lawn tractors, and beyond, this gearbox delivers the reliability and versatility you need to tackle any cutting job.

Why Choose the Rotary Mower Gearbox LF-227J?

The LF-227J isn’t just any gearbox—it’s a powerhouse designed to handle the rigors of rotary mowing. With a 1:1.83 gear ratio and a maximum input power of 55 kW (75 HP), it’s got the muscle to drive mower blades efficiently. Weighing in at 37 kg, its sturdy cast-iron GGG40 housing stands up to the stresses of daily use, while large bearings and hardened gears ensure a long lifespan. Whether you’re maintaining a sprawling farm or a manicured lawn, this gearbox is your go-to solution.

What sets it apart? Its oil bath lubrication system keeps everything running smoothly, reducing friction and wear with SAE 80W-90 oil (max capacity: 0.8 liters). Add in an oil seal to prevent leaks, and you’ve got a unit that’s low-maintenance and built to last.

Key Features That Set LF-227J Apart

• Tough as Nails: The cast-iron housing shrugs off the bumps and bangs of fieldwork.
• High Load Capacity: Big bearings and gears handle heavy-duty cutting with ease.
• Smooth Operator: The oil bath system keeps internals slick, cutting down on wear.
• Plug-and-Play: Easy to install—no custom tweaks needed for most mowers.
• Low Fuss: Minimal maintenance means more time mowing, less time tinkering.

From small lawn tractors to large agricultural setups, the LF-227J adapts to your needs, making it a versatile choice for any rotary mower task.

Inside the LF-227J: Core Components

This gearbox is a symphony of parts working together:

1. Input Shaft: Connects to your tractor’s PTO (1 3/8" 6-spline) to pull in power.
2. Gears: Hardened for heavy loads, they transfer torque at a 1:1.83 ratio.
3. Bearings: Support the spinning bits, keeping friction low.
4. Oil Seal: Locks in the lube, keeps out the grit.
5. Housing: Cast iron GGG40 shields the guts from the outside world.
6. Output Shaft: Sends 51.7 daNm of torque to your blades (ASA Z15 D.P. 8/16).
7. Lubrication System: Oil bath keeps it all humming along.

Regular checks—like peeking at the oil level or swapping seals—keep these parts in sync and your mower cutting clean.

How to Maintain Your LF-227J Gearbox

Want your gearbox to last? Here’s how to keep it in fighting shape:

• Check Oil Levels: Park it level, pull the dipstick, and make sure the oil’s between the marks. Top off with SAE 80W-90 if it’s low.
• Change Oil on Schedule: First swap after 50-70 hours, then every 500-700 hours or once a year.
• Watch for Leaks: A drip under the mower? Check that oil seal pronto.
• Listen Up: Weird noises? Could be bearings or gears—don’t wait to inspect.

A little TLC goes a long way toward avoiding big repairs.

Swapping out an old Comer LF-227J for TEBSA’s version? Safety first:

• Wear gloves and goggles—metal’s unforgiving.
• Disconnect the PTO shaft to avoid surprises.
• Secure the mower with jack stands—no wobbles allowed.
• Use a torque wrench—bolts need that 55 kW power handled right.
• Fill with 0.8 liters of SAE 80W-90 before firing it up.

Follow these steps, and your new LF-227J will slot in like it was born there.

PTO Shafts: The Perfect Pair

No gearbox runs solo—it needs a solid PTO shaft. The LF-227J pairs with a 1 3/8" 6-spline PTO shaft, hooking your tractor’s power to the mower’s muscle. Keep it greased, clean, and free of debris, and it’ll spin that 55 kW like a dream. TEBSA offers PTO options—540, 1000, or dual-speed—to match your setup.
