Cat 303E Mini excavators Expert review

Overview

The 2020 Cat 303E Mini Excavator, powered by a Cat C1.3-EF04 engine meeting Stage IV emissions standards, has demonstrated solid performance over approximately 5,305 operational hours. Manufactured in Japan, this machine is designed for tasks such as landscaping, utility work, and small-scale construction projects.​

Pros Its zero-radius tail swing allows for efficient operation in confined spaces, enhancing maneuverability on tight job sites.​ The ergonomic layout of the controls and the spacious cab contribute to reduced operator fatigue during extended use.​
Cons Some users have reported that certain hydraulic hoses are challenging to service due to the compact construction inherent in zero-turn mini excavators. ​Operators have noted that the machine can feel slightly tipsy over the tracks, particularly when lifting heavy loads.

What's new

The 2020 model of the Cat 303E introduced several updates aimed at improving transportability and performance. A notable change was the reduction in operating weight to approximately 3,310 kg (7,297 lb) for the canopy version, enabling easier transportation without compromising performance.

An optional 267-kg (588-lb) counterweight is available for users requiring additional stability during heavy-duty applications, bringing the machine's weight back to the previous model's 3,311 kg (7,300 lb).

The compact design, with a width of 1,550 mm (60 inches) across the blade and zero-radius tail swing, allows the 303E to operate efficiently in tight spaces and congested job sites.

Efficiency and performance

In day-to-day operations, the Cat 303E has proven to be a reliable and efficient machine. Its compact size and zero-tail-swing design make it particularly effective in urban environments and confined work areas. The machine's digging capabilities are commendable, allowing for precise excavation tasks.​

However, some operators have observed that the machine can become slightly unstable when lifting heavy loads, indicating a need for cautious operation in such scenarios. ​

Routine maintenance is straightforward, with accessible service points that facilitate quick inspections and servicing, thereby minimizing downtime.​

In-cabin and interior features

The operator station of the Cat 303E is designed with user comfort in mind. The ergonomic layout ensures that controls are within easy reach, and the spacious cab provides ample room for operators of varying sizes. These features contribute to a comfortable working environment, reducing fatigue during long shifts.​

Visibility from the cab is adequate, allowing operators to have a clear view of the work area, which enhances operational safety and precision.​

Safety features

Safety features of the Cat 303E include a certified lifting eye on the bucket linkage, facilitating secure lifting operations. The machine's design ensures that auxiliary hydraulic lines are equipped with quick connects, allowing for safe and efficient attachment changes.​

The robust construction of the machine, combined with its stable operation, minimizes the likelihood of accidents due to equipment failure. The operator station's design ensures clear visibility of the work area, further enhancing operational safety.​

In comparison

Compared to previous models, the 2020 Cat 303E offers improved transportability due to its reduced weight, making it more convenient for operators who frequently move equipment between job sites. The optional counterweight provides flexibility, allowing users to tailor the machine's stability to their specific needs.

When compared to competitors in the same class, such as the Bobcat E32, some users have noted that Cat machines can be slower and consume more fuel, potentially due to differences in hydraulic system configurations. However, the Cat 303E's operator comfort and control layout are often highlighted as positive aspects, making it a strong contender in the mini excavator market.

Verdict

The 2020 Cat 303E Mini Excavator earns a solid 5-star rating for its compact design, operator comfort, and reliable performance. While there are minor concerns regarding hydraulic hose accessibility and stability under heavy loads, the machine's overall capabilities and features make it a valuable asset for various construction and landscaping projects.
