Overview
The MF865 ext* is an industrial-grade, backhoe loader manufactured by MF Industrial and introduced in 1997, featuring side shift or center mount, reach and operating weight capabilities, and a Perkins 1004.4 TLR2 engine powering the machine. In this article, we’ll assess the advantages, disadvantages, and practical applications of the MF865 ext*’s features and specifications.
Advantages
SAE Dig Depth and Reach
The MF865 ext* features an SAE dig depth of 5860mm and a reach of 7030mm at ground level, which gives it a distinct advantage over many other similar industrial-grade backhoe loaders that run in this class. This means that the MF865 ext* can reach depths and areas where a conventional machine may not, making it useful in a wide variety of applications that require excavation or lifting. Additionally, with its SAE dig depth rating, the MF865 ext* can meet or exceed even the most demanding work requirements.
Breakout Forces
The MF865 ext* has fairly high breakout forces, with 5260kgf for the bucket and 3300kgf for the dipper. Though these forces are not necessarily extreme, they are well above the average for similarly-sized machines. This extra power can be extremely useful for digging through tougher materials or when dealing with stuck debris. Additionally, this power can help to ensure that the MF865 ext* functions properly regardless of its application.
Engine Power
The MF865 ext* features a relatively high amount of engine power, with a 67kW rating a 2200rpm. This high amount of power allows the MF865 ext* to move through most terrain with ease, while also allowing it to carry heavier loads than many other backhoe loaders of the same class. This makes the MF865 ext* perfect for applications that involve carrying loads over long distances.
Disadvantages
Bucket Width
The MF865 ext*’s bucket width is listed as 305-900mm, which is fairly restrictive considering the size of the machine. This means the MF865 ext* may not be suitable for certain applications that require a wide bucket, such as those involving sludge or large debris. Additionally, the narrow bucket may prove difficult to use in certain environments where other machines with wider buckets would have an advantage.
Relief Valve Pressure
The MF865 ext*’s relief valve pressure is rated at only 225bar, which is fairly low for this class of machine. This means that the MF865 ext* may not be able to handle high-pressure applications, such as those involving plumbing or drain-clearing, where higher pressure is required. Additionally, it is likely that the MF865 ext*’s relief valve will need to be replaced more frequently than those of other backhoes in its class.
Cylinder Slew System
The MF865 ext* uses a cylinder slew system, which is an outdated technology compared to more modern slewing systems such as hydraulic. This means that the MF865 ext* may not be able to move as quickly or accurately as other machines in its class. Additionally, the cylinder slew system is prone to malfunctions and breakdowns, which can make the MF865 ext* unreliable and potentially dangerous.
Real-World Examples
Advantages
A great real-world example of the benefits of the MF865 ext*’s SAE dig depth and reach capabilities is in underground construction projects, where digging or lifting may be required in depths or areas inaccessible to other backhoe loaders. Additionally, the MF865 ext*’s high breakout forces and engine power are ideal for many excavation, clearing, and lifting projects, such as those involving railroad tracks or man-made ponds.
Disadvantages
A real-world example of the limitation of the MF865 ext*’s bucket width would be in construction projects that involve large objects, such as sludge or heavy debris. In such cases, a machine with a wider bucket would likely provide more efficient operation. Similarly, the lack of a modern slewing system, combined with the low relief valve pressure, means that the MF865 ext* is likely not suitable for many plumbing or drain-clearing applications, where higher pressure and precision are required.
Overall Assessment
The MF865 ext* is a reliable and powerful industrial-grade backhoe loader with a variety of features and specifications that make it suitable for a wide range of applications. However, it has several notable disadvantages, such as the relatively small bucket width, the low relief valve pressure, and the outdated cylinder slew system, which may limit its usability in some scenarios and applications. All said, the MF865 ext* is a good choice for most projects and applications that don’t require extreme precision or power.
