Depending on the size category of the excavator, you usually have three arms to choose from: standard arm, long arm and extra long arm. For most types of excavators, the standard arm configuration generally provides the best lifting capacity and pulling force.
Choose long arms, or extra long arms, and you can reach further and dig deeper. These excavator arms are particularly useful in space-constrained situations, such as downhill slopes. However, as arm length increases, you lose some lift and penetration. In some cases, a larger counterweight for excavators with long or extra long arms can help maintain some of their digging power.

Some manufacturers offer a unidirectional auxiliary hydraulic system as standard equipment. Other excavators have a bi-directional auxiliary hydraulic system as standard equipment. If you intend to run attachments in the future, such as a thumb on an excavator, then you may need a two-way hydraulic system. If you are sure you can only dig, you may choose to dig in one direction.
Another reason to choose a two-way auxiliary hydraulic system is if you are using a multi-function accessory. If you think you will be using an angled tilt bucket or any other tilt attachment, you may want this option.
Cab options vary from manufacturer to manufacturer, but there are a few popular features. One is to add front and side lighting to the cab. Additional halogen or LED lights can extend your working hours.

Cameras are also becoming more common. Rear view mirrors are now standard on many tracked excavators and can be added to some mini-excavators. Some manufacturers also offer side view cameras as an option. They are particularly handy when rotating in crowded workplaces.
Cab guards with front and side view windows are another option you can find on the market. Customers working in the demolition, forestry and recycling industries often use window guards in their cabs. These guards provide additional protection for the operator from environmental hazards. You can choose a specially designed forestry taxi for your machine. Forestry taxis offer greater protection against falling objects.
Many excavator manufacturers offer a straight pedal option. This feature makes it easier for the operator to move in a straight line and is popular in ditching applications.
When you purchase an excavator, you may have several options when it comes to landing gear, depending on the size of the machine.
Tracks for medium and small excavators may be steel or rubber. Rubber tracks are common on small excavators and large excavators. For steel tracks, a common choice is the width of your track shoes. Wider running shoes can provide more flotation.
Many mini-excavator manufacturers offer angled or straight (dozer) blades. Blades provide extra stability when digging and allow for light backfilling. Angled blades allow you to adjust the angle of the blade to strengthen material placed left or right.
