What is the 480mm blade for the NG504 R300228 series mower and why you should choose it?
BLADE 480MM FOR NG504 SERIES MOWER R300228 is the working element of the mower responsible for the proper cutting of grass and its flow under the housing of the machine. It is made of durable, hardened steel, resistant to abrasion and impact with small stones or twigs, which significantly extends its service life. Standard length of 480 mm allows for efficient mowing of medium and larger lawn areas while maintaining high cutting precision.
Thanks to the presence of blades at both ends, the blade acts not only as a blade, but also as a rotor - it produces a strong airflow that lifts the blades of grass before cutting, and then transports them to the basket or tosses them aside. This solution keeps the grass trimmed evenly, without jagged ends, which promotes healthy growth and reduces yellowing of the tips.
The blade is factory-balanced to minimize vibrations transmitted to the mower shaft, housing and operator handle. Reduced vibration significantly improves working comfort and reduces wear and tear on other components of the machine, such as bearings and motor mounts.

Where does the 480mm blade for the NG504 R300228 series mower mount and what equipment it works with??
The R300228 blade is mounted on the working shaft of the mower, directly under the cutting housing. This is a spare part designed primarily for NG504 series mowers, but thanks to the standard dimensions of the holes it can also be used in other models whose design corresponds to the specified technical parameters. The key mounting dimensions are:
- total blade length: 480 mm,
- blade width: 56 mm,
- material thickness: 4 mm,
- center hole diameter: 18 mm,
- diameter of side holes: 8.5 mm,
- distance between side openings: 65 mm,
- design with blades floating grass.
Installation of the blade is simple, but it requires compliance with safety rules: before starting work, disconnect the power supply to the mower (in the case of combustion equipment - remove the pipe from the spark plug, in electric - unplug the plug from the socket). The blade is screwed with the central screw and additional side screws (if provided for the model), using the existing mounting holes with a diameter of 18 mm and 8.5 mm.
The 480mm blade for the NG504 series mower R300228 will be ideal for mowers used for grooming:
- home gardens,
- recreational areas next to summer cottages,
- small green areas at companies, schools or institutions,
- allotment gardens and neighborhood squares.

Use of NG504 R300228 mower blade in daily lawn care
The 480MM blade for NG504 series mower R300228 is designed for multi-season, heavy-duty use. Its solid thickness of 4 mm provides high resistance to deformation, so that the knife retains the correct shape and balance for a long time. Integrated blades improve air circulation under the lawnmower housing, thereby improving grass collection in the trash or more efficient dumping to the side.
Practical applications include:
- Regular mowing of well-maintained lawns - thanks to even cutting you get perfectly smooth turf without "clumps" and unevenness.
- Trimming taller grass after a period of intensive growth - Robust blade copes with denser and taller vegetation, gradually restoring the lawn to the desired level.
- Maintenance of areas around the house and company buildings - Aesthetic appearance of greenery improves the perception of the entire property by visitors and customers.
Thanks to its appropriately sized and bladed design, the knife ensures effective work even in more difficult conditions, such as slightly damp grass or terrain with slight unevenness. Sharp cutting edges reduce drag during mowing, which can have a beneficial effect on engine load and fuel or electricity consumption.

Blade 480mm for NG504 series mower R300228 - durability, safety and comfort of use
One of the key advantages of the R300228 knife is its high durability. Thickness of 4 mm and properly selected material provide resistance to:
- intensive use over large areas,
- occasional blows against small obstacles (stones, cones, twigs),
- wear and tear caused by frequent sharpening.
From the point of view of user safety, it is equally important to balance the blade correctly. Reduced vibration means not only comfort at work, but also less risk of damage to fasteners or knife breakage due to material fatigue. Properly attached and tightened blade with proper operation ensures stable and safe operation of the mower.
Examples of situations in which the user will appreciate the quality and reliability of this knife:
- Regular maintenance of the family garden - without the need to frequently replace the blade or straighten it after accidentally driving over a bump.
- Maintenance of the allotment garden - When the mower is used several times a week during the season, and the tool must reliably perform its function.
- Maintenance of areas around companies and institutional headquarters - where repeatable, professional mowing results and equipment reliability counts.

FAQ - Frequently asked questions about the 480mm blade for the NG504 R300228 series mower
Question 1: Will this blade fit my mower?
The 480mm R300228 blade is primarily designed for NG504 series mowers. It can also fit other models, provided that the length of the blade, the diameter of the central hole (18 mm), the diameter of the side holes (8.5 mm) and the distance between them (65 mm) are compatible. Before you buy, compare these dimensions with the original blade or documentation of your mower.
Question 2: How often should you replace the blade on your lawn mower??
Frequency of replacement depends on the intensity of use and operating conditions. For standard household use, it is recommended to check the condition of the blade at least once a season. If the blade is severely dulled, crooked or cracked, it is necessary to replace it. Regular sharpening and attention to balance can extend the life of the knife.
Question 3: Is it possible to sharpen the knife yourself?
Yes, you can sharpen the knife yourself, but it should be done with safety and attention to the balance of the blade. After sharpening, it's a good idea to check the balance of the blade to avoid excessive vibration during mower operation. If you have no experience, it is recommended that you use the service.
Question 4: How to safely replace the blade on a lawn mower?
Before replacing the blade, disconnect the power supply to the mower - on internal combustion models, remove the pipe from the spark plug, and on electric models, remove the plug from the outlet. Position the mower so that you have easy access to the blade, block the rotation of the shaft (for example, with a wooden block), and then remove the mounting screws. Install the new 480mm blade R300228, paying attention to the correct installation direction (the blades must lift the grass upwards), then tighten the screws firmly according to the recommendations of the manufacturer of the device.
Question 5: What are the benefits of using a blade knife?
The blade with blades not only cuts the grass, but also generates an air stream that lifts the blades before cutting and then transports them toward the basket or side ejection. This results in more accurate mowing, evenly cut grass and more efficient swath collection. The end result is an aesthetically pleasing, well-maintained lawn that looks professional after every pass with the mower.
