John Deere 710D ext*, 1999 Technical Specifications

Introduction

John Deere 710D ext* is a backhoe loader that has proved efficient in construction, agriculture, and mining. It is designed for heavy-duty work in rough terrains. The loader has several features and specifications that make it stand out among its peers. This article delves into the advantages and disadvantages of its features and specifications while highlighting practical scenarios that illustrate their real-world applications.

SideShift or CenterMount

The John Deere 710D ext* can be fitted with a sideshift or center-mount system. The sideshift system allows the movement of the excavator arm to the left or right of the machine, making it easy to excavate in tight spaces. The sideshift system is best suited for construction sites where there is limited space to maneuver. On the other hand, the center-mount system is ideal for large excavation work, such as digging foundation trenches. The center-mount system provides a stable base to support the excavator’s movements, reducing the likelihood of accidents.

SAE dig depth (mm)

The SAE dig depth is the maximum depth that the excavator can reach. The John Deere 710D ext* SAE dig depth is 7030mm, which is impressive. This feature makes it possible to dig deeper trenches, excavate foundations, and move large amounts of materials in a single scoop. However, deeper digging requires stability, and if the machine is not correctly balanced, it can tip over, leading to accidents.

Reach @ ground level (mm)

The reach at ground level measures how far the excavator’s arm can extend while maintaining stability. The John Deere 710D ext* has a reach of 8100mm. This feature allows the machine to excavate materials placed far away from the machine, reducing the need for the operator to move the machine frequently. This application is beneficial in agriculture, where crops are grown along fences, and in construction, where the materials are stored in a single place.

Loading height (mm)

The loading height is the height of the bucket when it is fully extended. The John Deere 710D ext* has a loading height of 4650mm. This feature enables the machine to load materials from high places, such as a lorry’s bed, without the need for a ramp. This feature is beneficial in construction, where materials need to be loaded onto the machine from high platforms.

Bucket width, min-max (mm)

The bucket width is the width of the excavator’s scoop. The John Deere 710D ext* has a bucket width of 457-914mm. This feature enables the machine to excavate areas of different widths. The bucket width’s versatility is ideal for excavation of trenches of varying widths and hauling of different materials.

Bucket/Dipper Breakout (kgf)

The bucket/dipper breakout is the force that the machine can exert on the ground while digging. The John Deere 710D ext* has a bucket breakout force of 6250kgf and a dipper breakout force of 2980kgf. These values are impressive and enable the machine to dig through hard surfaces easily. However, a strong breakout force requires stability, or the machine can tip over, leading to accidents.

Slew System

The John Deere 710D ext* uses a cylinder slew system. The cylinder slew system uses hydraulic cylinders to move the excavator arm. This feature provides the machine with a smooth and precise movement, reducing the chances of accidents. The cylinder slew system is ideal for applications where precision is required, such as digging trenches near existing structures.

Loader Bucket Capacity (m3)

The loader bucket capacity is the amount of material that the bucket can hold. The John Deere 710D ext* has a loader bucket capacity of 1.34m3. This feature enables the machine to move large amounts of materials in a single scoop, reducing the time taken to complete a task. The loader bucket capacity is ideal for agriculture, where large amounts of soil, sand, and gravel need to be moved at a time.

Dump height (mm)

The dump height is the maximum height that the machine can lift the bucket. The John Deere 710D ext* has a dump height of 2880mm. This feature enables the machine to dump the excavated materials into high platforms without the need for a ramp. The dump height is beneficial in construction, where the materials need to be dumped into high trucks or containers.

Engine Make & Model, Power and Displacement

The engine is the heart of the machine, and the John Deere 710D ext* features a JD 6-059T engine. The engine produces 86kW@2200rpm and has a displacement of 5.88lit. This feature enables the machine to move with ease in rough terrains while consuming less fuel. Additionally, the engine’s power is sufficient to support the various machine functions.

Number of Cylinders/Pump Type/Pump Flow/Relief Valve Pressure

The John Deere 710D ext* has a 6-cylinder engine. The machine has a CCRP-type pump with a flow rate of 201lit/min and a relief valve pressure of 175bar. These specifications enable the machine to move with ease while supporting the machine’s functions’ hydraulic needs.

Transmission type/ Drive/ Speeds, FR/ Maximum speed (km/h)/Ride control

The John Deere 710D ext* has a Full PS TC transmission type with a 2WD/4WD drive. The machine can achieve speeds of up to 31km/h, making it fast and efficient in moving across large distances. Additionally, the machine has a ride control feature that improves stability, reduces vibration, and improves the operator’s comfort.

Travel Length/Height (mm) & Width/Turn Circle Radius without Brakes (mm)/Operating Weight (kg)

The John Deere 710D ext* has a travel length of 8130mm, travel height of 4310mm, and a width of 2440mm. Additionally, the machine has a turn circle radius without brakes of 11540mm, making it easy to maneuver around tight spaces. The machine’s operating weight is 12360kg, making it stable and less prone to accidents.

Overall Assessment

The John Deere 710D ext* is an efficient and robust machine designed for heavy-duty work in rough terrains. The machine features impressive specifications and numerous advantages that make it suitable for construction, agriculture, and mining. However, the machine’s features require stability to avoid accidents, and the operator needs to exercise caution when operating the machine.
