The Kubota B5100 is a compact and versatile tractor, ideal for small-scale farming and landscaping applications. Its compact size and powerful engine make it easy to maneuver around tight spaces and uneven terrain. In contrast, its advanced features and attachments make it a versatile tool for various tasks.

In this Kubota B5100 review, we’ll take a closer look at the features, design, and performance of the Kubota B5100 and discuss its strengths and weaknesses. We’ll also talk about its usability, comfort, ease of maintenance, and overall value for the price.

That being said, let’s get right into it!

Kubota B5100 Review

Before diving into the significant drawbacks of the Kubota B5100, let’s first highlight the unique features that make this tractor stand out.

Automatic Transmission and Electric Clutch 

The Kubota B5100 tractor is equipped with a hydrostatic transmission, a type of automatic transmission that uses a hydraulic pump and motor to drive the tractor’s wheels rather than a traditional gearbox.

This allows the tractor to be operated smoothly without the need to shift gears. The operator can easily adjust the speed and direction of the tractor by using the foot pedal or hand lever.

An electric clutch is not equipped on the Kubota B5100 tractor; it features a traditional mechanical clutch instead. The clutch engages and disengages the tractor’s transmission from the engine.

The operator can use the clutch pedal to disengage the transmission when starting the tractor, shifting gears, or stopping the tractor. The mechanical clutch is reliable and requires minimal maintenance.

Comfortable Design

The Kubota B5100 is designed with the operator’s comfort in mind; it features a high-back seat with a suspension system that helps to reduce vibrations and shocks, making it more comfortable to operate even on rough terrain.

The seat also has adjustable armrests and a backrest that can be adjusted to suit the operator’s preferences. The operator’s station is also designed to be ergonomic, with a wide, comfortable footrest and a steering wheel that’s super easy to grip and maneuver.

Additionally, the controls are placed in an easy-to-reach location, making it a breeze to access them without stretching or moving around.

The tractor’s cab is designed to be spacious and well-ventilated, providing a comfortable environment for the operator to work in. It also has large windows that provide good visibility, allowing the operator to see the work area clearly.

Overall, the Kubota B5100 tractor’s comfortable design helps reduce operator fatigue and discomfort, making it easy to work for long periods of time. The tractor’s ergonomic design and comfortable operator’s station also help to increase productivity and efficiency.


The durability of the Kubota B5100 depends on several factors, such as how it’s been used, maintained, and stored. In general, Kubota tractors are known for their durability and longevity, and the B5100 is no exception.

The B5100 is made with high-quality materials and components that are designed to withstand the rigors of regular use. The tractor’s diesel engine is built to last and is designed to provide reliable performance even in demanding conditions.

The hydrostatic transmission is also built to last and requires minimal maintenance. Moreover, the tractor’s frame and body are also designed to be durable, with sturdy construction that can withstand heavy loads and regular use.

Not to mention that its suspension system helps to reduce vibrations and shocks, which can help to prolong the life of the tractor’s components.

  • Pro tip: If you want to increase the durability of your Kubota B5100 further and keep it running smoothly, regularly check and maintain the engine oil, oil filter, air filter, fuel filter, and other components.

Easy Maintenance 

The tractor’s simple, easy-to-use design makes it easy to perform regular maintenance tasks, such as oil changes and filter replacements.

Its diesel engine is also designed to be easy to maintain, with a relatively simple design that makes it easy to access key components for maintenance and repairs.

Additionally, Kubota B5100’s hydrostatic transmission is designed to require minimal maintenance—the transmission oil is sealed and doesn’t require changing. The transmission’s filter is also easy to access, making it easy to change when needed.

  • Note: For regular maintenance of the Kubota B5100, always consult the owner’s manual for recommended tasks and schedules.

Kubota B5100 Problems

Like any tractor, the Kubota B5100 has its own set of cons that may be a deal-breaker for some operators. Here are a few common problems that you might encounter:

1. Limited Lifting Capacity

The B5100 tractor has a relatively low lifting capacity, making it difficult to handle heavy loads or attachments. This can be a problem for those who need to move or lift large or heavy objects with the tractor.

2. No Power Steering

The B5100 tractor doesn’t have power steering, making it challenging to maneuver in tight spaces or around obstacles. This can be particularly difficult for older or physically weaker operators.

3. Limited Speed Range

The B5100 tractor has a relatively limited speed range, making it harder to work in large or open areas. This can be a problem for those who need to cover a lot of ground in a short amount of time.

4. Lack of a Cab

Some versions of the B5100 tractor don’t come with a cab, making it uncomfortable to operate in bad weather or dusty conditions. So, if you constantly need to work in adverse weather conditions or dusty environments, the B5100 may not be the tractor for you.

5. Not Suitable for Heavy-Duty Tasks

Another drawback of the B5100 tractor is that it’s designed for small-scale farming and landscaping operations and may not be suitable for heavy-duty tasks such as commercial construction or large-scale farming.

6. Lack of Advanced Features

The B5100 tractor is a basic model and lacks some useful advanced features that might be present in larger, more expensive tractors, such as GPS navigation or advanced monitoring systems.

Kubota B5100 Price

The price of the Kubota B5100 tractor can vary depending on the year of manufacture, dealer, location, the condition of the tractor, and the specific features that come with the tractor.

And while the initial price of the Kubota B5100 tractor when it was first introduced to the market is not widely available online, a used Kubota B5100 tractor can cost you between $5,000-$8,000 depending on the aforementioned factors.

On the other hand, a brand-new Kubota B5100 can range from $9,000 to $12,000.

Overall, the Kubota B5100 is a relatively affordable tractor, and its price is in line with similar compact tractors. But it’s still not the cheapest option on the market.
