Kubota KX71 Tracks
The Kubota KX71-3 compact excavator can be equipped with either rubber tracks or steel tracks, depending on your specific needs and the terrain in which you’ll be operating the machine.
Both types of tracks have their advantages, and the choice depends on factors like the type of work you’ll be doing and the ground conditions. Here’s a brief overview of both track options:
- Rubber Tracks:
- Rubber tracks are a popular choice for compact excavators like the KX71-3 because they are versatile and suitable for a wide range of applications.
- Benefits of rubber tracks include lower ground pressure, which reduces the risk of damaging sensitive surfaces like lawns, asphalt, or concrete.
- Rubber tracks also provide improved traction and are less likely to cause surface damage, making them suitable for urban and residential construction sites.
- They tend to be quieter than steel tracks, which can be advantageous in noise-sensitive areas.
- Rubber tracks are less likely to leave marks on surfaces, making them a good choice for landscaping and maintenance tasks.
- Steel Tracks:
- Steel tracks are more durable and suitable for heavy-duty applications and harsh working conditions.
- They are less likely to wear out quickly, making them a good choice for tough terrains, rocky surfaces, or abrasive environments.
- Steel tracks provide better stability and traction in challenging conditions, making them suitable for off-road, forestry, or agricultural applications.
- They can handle higher weight loads and are less prone to punctures or cuts.
- Steel tracks may be more durable in the long run but can cause more surface damage and have a higher ground pressure compared to rubber tracks.
The choice between rubber and steel tracks ultimately depends on the specific requirements of your project and the ground conditions you’ll be working on.
If you require versatility and plan to work on a variety of surfaces, rubber tracks are often the preferred option. However, if you need the durability and stability for more challenging terrains, steel tracks may be the better choice.
Your local Kubota dealership can provide guidance on the most suitable track type for your needs and may offer options for switching between track types to suit different projects.
The Kubota KX71-3 excavator normally uses rubber tracks. Rubber tracks are a popular choice for mini excavators because they offer a number of advantages over steel tracks, including:
- Reduced ground damage: Rubber tracks are less likely to damage delicate surfaces, such as asphalt and concrete.
- Smoother ride: Rubber tracks provide a smoother ride than steel tracks, which can reduce operator fatigue and improve productivity.
- Reduced noise: Rubber tracks are quieter than steel tracks, making them ideal for jobs in urban areas or near sensitive noise receptors.
- Lower maintenance costs: Rubber tracks require less maintenance than steel tracks, which can save operators money in the long run.
The Kubota KX71-3 uses rubber tracks with a width of 230 mm, a pitch of 96 mm, and 31 links.
It is important to use the correct size and type of rubber tracks on your Kubota KX71-3 excavator. Using the wrong tracks can damage your excavator and reduce its performance.
Here are some tips for maintaining the rubber tracks on your Kubota KX71-3 excavator:
- Inspect the tracks regularly for signs of wear and tear. Replace the tracks if they are damaged or worn.
- Keep the tracks clean and free of debris.
- Avoid operating the excavator on sharp or abrasive surfaces.
- Tighten the track bolts regularly.
- Lubricate the track rollers and idlers according to the manufacturer’s recommendations.
By following these tips, you can help to extend the life of the rubber tracks on your Kubota KX71-3 excavator.
Here are some additional tips for using rubber tracks safely and effectively:
- Be careful not to overload the excavator. Overloading the excavator can damage the rubber tracks and make it difficult to control.
- Avoid operating the excavator on slopes that are too steep. Operating the excavator on steep slopes can increase the risk of the tracks slipping off.
- Be careful when moving the excavator in tight spaces. The rubber tracks can be damaged if they come into contact with obstacles.
However, this can vary depending on the terrain and the level of wear and tear on the tracks.It is recommended to inspect the tracks regularly for signs of wear and damage, such as cuts, tears, or missing lugs.
Kubota KX71-3 Buckets
- Standard Excavator Bucket:
- The standard bucket is the most common attachment for general-purpose digging and excavation tasks. It has a typical digging profile and is suitable for a wide range of soil and material types.
- Trenching Bucket:
- Trenching buckets are narrower and have a deeper profile, making them ideal for digging narrow trenches for utilities like water lines, gas lines, or electrical cables.
- Ditching Bucket:
- Ditching buckets have a wider profile and are used for shaping and creating ditches or trenches for drainage, irrigation, or other applications that require a wider excavation.
- Grading Bucket:
- Grading buckets are designed with a flat bottom and are used for leveling and grading tasks. They help achieve a smooth and level surface when working on landscaping or construction projects.
- Rock Bucket:
- Rock buckets are reinforced and equipped with heavy-duty teeth to handle rocky or challenging terrain. They are designed for digging in tough materials like rocky soil, gravel, or other hard surfaces.
- Skeleton Bucket:
- Skeleton buckets have openings in the bucket body, which allow smaller debris and fine materials to sift through while retaining larger objects. They are useful for separating materials like rocks and roots from soil.
- Cleanup Bucket:
- Cleanup buckets have a larger capacity and are designed for handling loose materials, such as soil, gravel, or debris. They are often used for loading materials into trucks or containers.
- Thumb Attachment:
- A thumb attachment can be added to the bucket to provide a gripping mechanism. It is useful for picking up and moving irregularly shaped objects, logs, rocks, or other materials.
