Kubota BX2370 Mower Deck Parts

1. Blades: These are the cutting components of the mower deck. Depending on the model, there could be one or more blades attached to the spindle assemblies.
2. Spindle Assemblies: Spindle assemblies hold the blades in place and allow them to rotate freely. They are mounted to the mower deck and connect to the drive system.
3. Belt(s): The mower deck is typically powered by one or more belts connected to the tractor’s power take-off (PTO) system. These belts transfer power from the tractor to the spindle assemblies, causing the blades to rotate.
4. Deck Shell: The deck shell is the main housing of the mower deck. It provides structural support and houses the blades, spindles, and other components.
5. Pulley System: Pulleys are used to route the belts around the mower deck, transferring power from the tractor to the blades. There are often multiple pulleys of different sizes to create the necessary belt tension and drive ratios.
6. Deck Wheels/Rollers: These wheels or rollers are mounted on the mower deck to provide support and stability, especially when mowing uneven terrain. They help prevent scalping and ensure an even cut.
7. Adjustment Mechanisms: Mower decks often have mechanisms for adjusting the cutting height. These can include levers, pins, or other systems that allow you to raise or lower the deck to achieve the desired grass height.
8. Mounting Hardware: Bolts, nuts, washers, and other hardware are used to assemble and secure the various components of the mower deck to the tractor.

Kubota BX2370 Battery

The Kubota BX2370 uses a Group 26R battery. This is a common battery size for sub-compact tractors and other small utility vehicles. Here are some specifications of the Kubota BX2370 battery:

• Voltage: 12 volts
• CCA (Cold Cranking Amps): 540
• BCI Group: 26R
• Terminal: Nut and bolt

Here are some things to consider when choosing a replacement battery for your Kubota BX2370:

• Make sure the battery has the correct CCA rating. The CCA rating is a measure of the battery’s ability to start the engine in cold weather.
• Choose a battery from a reputable brand. There are many different brands of batteries available, but it is important to choose a brand that has a good reputation for quality and performance.
• Consider the warranty. Most batteries come with a warranty, so be sure to check the warranty terms before you make a purchase.

Here are some popular replacement batteries for the Kubota BX2370:

• Kubota Genuine Battery (77700-00426): This is the OEM (original equipment manufacturer) battery for the Kubota BX2370. It is a good choice if you want a battery that is exactly the same as the original battery.
• Optima Batteries RedTop 34R (34R): This is a high-performance battery that is designed for cold weather starting. It is a good choice if you live in a cold climate or if you use your tractor in winter.
• X2 Power AGM Battery (X2-26R): This is an AGM (absorbed glass mat) battery that is maintenance-free and spill-proof. It is a good choice if you want a battery that is easy to care for and that will not leak.

Kubota BX2370 Backhoe Attachment

The Kubota BX2370, unfortunately, does not offer a factory-made backhoe attachment. This is because the tractor’s 23 horsepower engine and overall size are not designed to handle the demands of a backhoe.

However, there are two alternative options to consider if you need backhoe functionality with your BX2370:

1. Upgrading to a BX Model with a Backhoe:

Kubota offers other BX models, such as the BX25D and BX26S, that come with a backhoe attachment as standard equipment. These models have more powerful engines and are better suited for backhoe work.

2. Using an Aftermarket Backhoe Attachment:

Several aftermarket manufacturers offer backhoe attachments that can be adapted to fit the Kubota BX2370. However, it’s crucial to carefully consider the limitations of this option:

• Compatibility: Ensure the chosen aftermarket backhoe is specifically designed and compatible with the BX2370’s hydraulic system and lifting capacity.
• Performance: The BX2370’s smaller size and power might limit the backhoe’s digging depth, reach, and overall performance compared to factory-equipped models.
• Safety: Improper installation or exceeding the tractor’s capacity can lead to safety hazards. It’s essential to prioritize safe operation and follow the manufacturer’s instructions meticulously.

Here are some additional points to remember:

• Using an aftermarket backhoe might void your tractor’s warranty.
• Consult your Kubota dealer or a qualified mechanic for proper installation and guidance on using an aftermarket backhoe attachment safely and effectively.

Kubota BX2370 Lift Capacity

The Kubota BX2370’s lift capacity depends on two factors:

1. Lift point:

• Pivot pin at max height: 745 lbs (338 kg)
• 500mm forward at max height: 518 lbs (235 kg)

2. Bucket position:

• Ground level reach: 52.4 inches (1330 mm) with a 48-inch wide bucket
• Max lift height: 71.3 inches (1810 mm)

Important notes:

• These are the rated lift capacities under ideal conditions. Always prioritize safety and never exceed the recommended capacity.
• The lift capacity decreases as the lift point moves further away from the pivot pin. Consult the operator’s manual for a detailed chart showing the capacity at different lift points and boom angles.
• Factors like terrain, stability, and attachment weight can also affect the actual lift capacity. Always operate your tractor on level ground and avoid exceeding the total vehicle weight rating.
