Link-Belt expanded its X4S excavator lineup at the 2025 Utility Expo with its smallest model, the new 145 X4S, offering more tech options, increased power efficiency and an improved hydraulic system.
In the video above, Equipment World gets an in-depth walkaround of the new excavator.
Associate Product Manager Wyatt Skaggs says the 145 X4S fits well for contractors who need to move a lot of material in tight spaces. The 145 X4S’s minimal swing rotations make it ideal for working in alleys or on small highway jobsites, says Skaggs. Tail swing is 5 feet at a speed of 12.5 rpm, and swing torque is 27,400 pound-force.
The 145 can reach a max operating weight of 33,900 pounds with a 7,500-pound standard counterweight and 8-foot 6-inch dozer blade.
A key new feature can be found in the 145 X4S’s hydraulic system, where Link-Belt has paired an electronically controlled pump with its spool stroke control system, resulting in better efficiency and control, the company says.
The pilot pump offers a max flow of 5.3 gallons per minute using a 20-gallon hydraulic tank. Operators will get 4,970 psi (5,260 psi with Power Boost) on the boom arm, 4,050 psi on the swing circuit and 4,970 psi on the travel circuit.
Three new tech options can be added to the 145 X4S:
- Digital Level: a real-time display of the machine’s attachment height, roll and pitch.
- Height and Depth Alarm: operator-customized audible warnings and on-screen notifications.
- Payload Management: see bucket volume in real-time, track loading history and store up to six individual truck capacities and 10 bucket dimensions.
For using these new options, operators will find a high-definition, anti-glare, 10-inch LCD monitor, which can be customized to display different data including custom hydraulic work tool names.
Comfort has been improved with a high-back, tilting and heated seat. Standard tech includes the 145 X4S’s wide-angle visual enhancement system, featuring a 230-degree view around the machine.
Operators can choose from four power modes – SP, Power, Eco and Lift. A new 500-hour fuel-filter service interval allows for longer time between changes, and the 145 X4S does not require a diesel particulate filter.
The 145 X4S’s DEF tank has a consumption rate of only 2%-3% compared to diesel fuel, and the engine delivers 6% better fuel economy than its predecessor, the company says. The service points are all accessible from ground level.

So the 145 serves a great purpose for municipality work in the city. So tight spaces and still moving a lot of material.

My name is Wyatt Skaggs with Lincoln Excavators. I am an associate product manager here. Today I have behind me the 145 X for us. This is a continuation from the 145 x for. The differences between the two are going to be with the X4S features are going to standard features such as an HD bucket linkage, HD boom, and inside are going to have a rearmed cab over the X4.

With the x4 s, you're going to also have advanced features as optional, and those advanced features are going to be payload, high depth alarm and digital level. Those comes with optional payloads, a good feature to have for moving material out and weighing it. High depth alarm. It's going to be able to be able to set your limits a certain height and a certain depth based on foot or meters.

If you are in Canada and you want to do meters. So you'll notice on the back of this machine you'll kind of have a rounded edge. We call those MSR. So minimal swing rotations are great for inner city work, highway work, working in between, you know, kind of tight areas and be able to swing close to the tracks.
00:01:21:20 - 00:01:50:08

And it still moves a ton of material as well. So I think anyone that's bidding on a lot of city or state jobs that have to kind of navigate in tight areas. So if you think about your highways, everybody's came across a nice little commute to work where they're hit construction. It's good to have a machine such as the 145 to operate in those tight areas, that it can rotate in a tight area into in cities, looking down an alleyway, needing to do sewage line utility lines deep in the ground, but not being able to have a conventional tail slinging machine.

This serves a great purpose for that as well, just as a brand to as well. The 145 XT for us serves a great purpose for warranty and low cost of ownership. So five year 5000 hours low cost of ownership still gets the job done. 6% better fuel economy over the previous X4. So you're going to save money and still produce more money without losing productivity, which is very key.
00:02:11:18 - 00:02:27:04

With this machine. You also have precision grade brackets on the machine. So if you have great control yourself, it'll marry up to a Trimble system. So if your bid requires great control on the machine, it's very easy to install, very easy to calibrate as well.
