A compact excavator is the perfect way to get some serious digging done while using machinery with a small footprint, making it ideal for use in tight spaces or cramped quarters. Choosing the right compact excavator, however, is not always easy since there are so many different factors and considerations to keep in mind. The Hyundai R25Z-9AK, for example, is one of the smaller models available from Hyundai, which makes it a terrific choice if you need light-duty work done at a job site with small areas to use it in.If you are unsure of which compact excavator might be right for you, then come visit us at Quality Fleet Service to find the perfect option for your needs. Our knowledgeable salespeople have experience with the full lineup of Hyundai compact excavators, as well as larger models, and can work with you to figure out just what you need. With our large test pit, you can see how this sort of machinery will work in real-world conditions to judge, which would be best for you. Call us at Quality Fleet Service today to discuss your commercial equipment and machinery needs and discover everything we can do for you.

The Hyundai R25Z-9AK

Picking the right machinery for your business means knowing what you need and then finding the equipment that can handle such tasks. A compact excavator is a great choice for getting a lot of digging done when you do not have the kind of space available for a larger wheeled or crawler excavator. Although Hyundai offers a number of different models, the R25Z-9AK is one of their smaller and more light-duty options.

The Hyundai R25Z-9AK is powered by a Kubota diesel engine that delivers up to 23 hp and up to 60 lb-ft of torque, which is more than enough for a compact model like this. Since this is a smaller option, it has an operating weight of up to 5,640 lbs and comes with a standard bucket measuring 0.07 cu.m. or 0.09 cu.yd. in size. This model has a swing speed of up to 9.1 rpm, which is quick enough to get a decent amount of work done in no time.

You get a maximum travel speed of 2.7 mph with this compact excavator, and a maximum reverse speed of 1.5 mph so it can navigate your worksite pretty quickly. The R25Z-9AK has a maximum digging reach of nearly 15 feet and a maximum digging depth of just under 8 feet, so it works well for a wide range of tasks. It has a swing tail radius of just over 2 feet and a bucket breakout rating of over 4,000 lbs of force, with more than 3,000 lbs of digging force available.

If, after seeing these specs for the Hyundai R25Z-9AK, you are still unsure of if it is right for you, then come visit us at Quality Fleet Service. We have a large test pit at our facility where you can see different machines that we offer first-hand to judge their performance for yourself. This lets you get a good sense of how they will perform in real-world settings and decide on which model is right for you.

Excellent Hyundai Warranty Coverage

Although every manufacturer offers warranty coverage on their machinery, Hyundai is one of the best out there with extensive protection. The last thing you want to do is invest in equipment that might not last very long and lacks a good warranty from its manufacturer. When you see a great warranty, you know that the people that built a piece of equipment believe in it.

The Hyundai R25Z-9AK warranty coverage includes:

  • 3-year or 3,000-hour full machine warranty
  • 5-year or 10,000-hour structural warranty

While this is already great protection, you also have the option to get extended warranty coverage that includes up to 5 years or 10,000 hours of full machine protection. Best of all, you do not have to decide on the extended warranty at the time of purchase. For as long as your machinery is still under its original warranty, you can choose to extend that protection.

In addition to your machine coverage, whenever Hyundai factory parts are used in repairs, they come with 1-year or 1,500-hours of warranty protection. As a certified Hyundai service center, we use original factory parts whenever possible to ensure your equipment is covered as well as can be. It is all part of our commitment to providing you with the best machinery and service.
