The Hyundai R35Z-9A is a 3.5 tonne class zero tail swing compact excavator that gives UK contractors and hirers a lower-cost alternative to the equivalent Kubota, Takeuchi and JCB machines in the same size band.

Hyundai's UK dealer coverage for this class is thinner than the market leaders, spread across several regional appointed dealers.
