Closing Recommendation
Both machines come from the same family, so buy for the work you do in a normal month rather than for your hardest single job. Choose the Liebherr R 930 Litronic when your digging is steady, you move sites often, and you want lower diesel use, a quicker swing and easier, cheaper transport. Choose the Liebherr R 934 Litronic when your material is hard clay, packed murrum or weathered rock, you want more digging force and a bigger load each pass, and the machine will stay on one large site long enough to be worth the extra cost. So match the machine to your work: R 930 Litronic for steady cycles and low cost, R 934 Litronic for hard material and heavy digging.
