The Bobcat skid steer has a good reputation all over the world due to their tough build, trusted performance, and innovative design.
However, there are many different types of Bobcat skid steers, making the choice difficult. And that’s why this guide was born. We will introduce them by size, rated operating capacity (ROC), and power, helping you easily find the model that fits your job and budget.
What Is ROC: Rated Operating Capacity
Think of ROC as your loader’s safe lifting limit — just like knowing how much weight you can lift without losing balance.
In a skid‑steer, ROC means the maximum weight the machine can safely lift and carry without tipping forward.
It’s usually set at 50% of the skid‑steer’s tipping load.
Example:
If a machine tips at 3,400 lbs, its ROC would be 1,700 lbs.
That’s the safe, stable weight you can lift all day without risk.
- Higher ROC = more lifting power
- Lower ROC = more agility in tight spaces
Understanding ROC helps you quickly choose whether you need a small, medium, or large‑frame Bobcat skid‑steer for your job.
Small‑Frame Skid Steers
ROC < 1,700 lbs
Ideal for tight spaces, landscaping, and farm jobs.
These loaders are light, narrow, and easy to transport — perfect for gates, garages, and indoor work. For a broader look at this category across brands, check out our Most Complete Mini Skid Steer Models Guide.
