Software Updates For Cat 303.5 CR Mini Excavator

Oct 29, 2025 - 7 months ago

The next generation compact radius Cat 303.5 CR Mini Hydraulic Excavator features a significant software update designed to improve transient speeds up to 25% compared to previous 303.5 CR next gen models.

“While the top end speed hasn’t changed, how the machine gets from ‘0 to 60’ has. It’s much faster from the start,” says Greg Worley, market professional for Cat mini excavators.

The 303.5 CR’s more dynamic design with quick transient speeds helps to reposition the excavator in a shorter period, limiting the time the machine is not working. This results in contractors being up to 35% more productive at the jobsite, depending on application and conditions.

The update is compatible with all next generation builds dating back to the first production models in 2021. The current software version is available on the excavator’s operating monitor, and customers can get the latest update from their Cat dealer.
