The Cat 308 excavator is designed to excel in medium duty applications. This machine has a conventional tail swing design that provides greater versatility and an unobstructed view of the jobsite. The cab is ergonomically designed for maximum operator comfort, safety, and productivity. This standard tail swing machine has performance, reliability and durability built into every hydraulic excavator component. With a focus on performance and practicality, this excavator delivers power and efficiency to help you complete your work on time and within budget.

The Bobcat E85’s spacious operator station has been designed with the operator in mind with excellent visibility, high comfort levels and intuitive control layout. The spacious cabin features excellent all-round visibility, making it ideal for working in confined spaces while keeping the operator comfortable during long working days. It is equipped with Electronic Pilot Controls (EPC), which provide improved control response and increased productivity. The EPC system helps reduce fatigue by allowing more precise digging movements from the joystick controls, resulting in less wasted effort by the operator and reduced fatigue after a long day’s work.

The Cat 308E CR uses a hydraulically driven cooling fan to help reduce noise and fuel consumption. The Bobcat E85 has an electric fan.

Because the cooling fan in the Cat 308E CR is only driven when needed, it uses less fuel than the electric fan that is always on in the Bobcat E85. This makes the Cat 308E CR’s diesel engine more efficient and cost-effective than the Bobcat E85’s diesel engine.

With its hydraulically driven cooling fan, the Cat 308E CR creates less noise than the Bobcat E85. This makes the operation of this machine quieter and safer for its operator and nearby workers.

Bucket size – Bucket size is a huge factor when choosing an excavator for your job. If you have to move massive amounts of earth in a short period of time, it’s better to choose a larger bucket size. However, if you are performing delicate work such as grabbing objects without damaging them or digging along foundations, it’s better to choose a smaller bucket size.

Machine weight – Weight is another factor to consider when renting an excavator. The heavier the machine, the more force it can exert on an object. This can be beneficial if you need to break up rock or concrete but can be a hindrance if you need to perform delicate work. You will also want to consider how much space you have available at your jobsite and whether you need additional equipment like cranes or forklifts to move the machine into place. Another thing to consider is whether or not there is any weight restrictions on bridges or roads in your area that may limit.

cat 308 vs bobcat e85 Excavator | Performance

The Cat 308 and Bobcat E85 are both 8 metric ton (8.8 ton) mid-sized excavators. Both machines are built specifically for the rental market with a focus on maximizing productivity, versatility and ease of operation. So how do they perform against one another?

We put both machines through their paces in a series of tests to highlight their differences in performance. Each of these tests was conducted on the same day, with similar ground conditions, bucket sizes and operator experience in order to eliminate as many variables as possible. Key metrics were recorded for each test and compared for analysis.

Although we only tested two machines here there are many differences between brands and models that can greatly affect how they perform on the job site. For example:

Different hydraulics systems at work

Different operators (experience level, training)

Different sized buckets (width & capacity)

Differences in ground conditions (elevation & soil quality)

Can someone please tell me the difference in weight between these two machines. I am trying to determine if a Bobcat E85 (80,000 lbs) can be transported legally with a tandem axle truck on the interstate. I have read that you need to be licensed for over 70,000 lbs which would mean triple axles. I have also heard that tandem axles are fine as long as the truck is under 80,000 lbs and the trailer is under 26,000 lbs.
