Closing Recommendation
Both are very large Liebherr mining excavators, so pick by your output target, your ground and your truck size. Choose the Liebherr R 9350 G6 when you need maximum production, a bigger bucket and more digging force, and the ground under it is firm enough for a heavier machine. Choose the Liebherr R 9300 G8 when the mine has softer benches where a lighter footprint and lower ground pressure help, and when easier transport suits you, with AC and GPS as standard. Also confirm Liebherr service and parts can reach your mine fast. So match the machine to your work: R 9350 G6 for top production on firm ground, R 9300 G8 for soft benches and a lighter footprint.
