Replacing a previous machine with an R-Series compact excavator

With the launch of the R2-Series compact excavators, there’s not an exact excavator to take the place of the M-Series E45. If you’ve been loyal to the E45 but are in need of a new machine, we recommend trying the R2-Series E42, which is comparable to the E45 excavator.

The E45 and E42 have a similar horsepower, operating weight, arm digging force, bucket digging force, travel speed, maximum dig depth and maximum dump height, with the E42 compact excavator performing slightly better in arm digging force, bucket digging force and maximum dump height.

If you’re looking for a lifting capacity and maximum reach at ground level that’s similar to the M-Series E45, we recommend trying the larger R2-Series E50 excavator.

If you’re still not sure which R2-Series excavator would best meet your needs in comparison to the E45, reach out to your local dealer for more information.
