They do not have an excavator on the back but do have a loader mounted on the front.
Difference between skid steer and front end loader.
Skid steer loaders are smaller and more compact than backhoes which means they are usually more maneuverable and can work in smaller spaces.
Skid steer loaders tend to have a little higher flow compared to wheel loaders.
A skid loader skid steer loader or skidsteer is a small rigid frame engine powered machine with lift arms that can attach to a wide variety of labor saving tools or attachments.
It comes with its own advantages.
First it is much smaller than a backhoe hence can fit in very small spaces.
In addition this equipment can be attached with many accessories on the front end which makes it more versatile than a backhoe.
The skid steer loader on the other hand is not a simple machine.
A typical skid steer with an empty bucket will have about 70 percent of its weight in the rear and 30 percent up front.
In addition the front end loader can be replaced with other accessories that allow it to do more.
Skid steer loaders are typically four wheel vehicles with the wheels mechanically locked in synchronization on each side and where the left side drive wheels can be driven independently of the right side drive wheels.
Furthermore the hydraulic flow rate of skid steers and wheel loaders can differ which also is a consideration in utilization of attachments says david morice compact equipment business unit manager for yanmar america.
