Drive 21 Self-Propelled Mower for Larger Australian Lawns A fusion of class-leading direct drive gearbox, an all-alloy cutter housing, the ultra-reliable Kohler XTX775 four-stroke engine, coupled with the larger 230 mm ball bearing wheels and the renowned COX-engineered swing-back blade system, guarantees a proven and consistent performance across all conditions. The COX Drive 19 and Drive 21 are self-propelled push mowers designed for Australian lawns where reliability and ease of use matter more than unnecessary features. Both models are powered by proven COX-engineered engines and feature the swing-back blade system that has been a COX trademark across the push mower range - a practical design that absorbs impact when striking obstacles rather than bending or damaging the blade. The 19" model suits standard suburban blocks where manoeuvrability is important and the operator wants a lighter, responsive machine. The 21" model covers more ground per pass, making it better suited to larger lawns where cutting time is a consideration. Both models are drive-assisted, reducing physical effort on larger areas or inclines. Suitable for homeowners maintaining regular domestic lawns, and well suited to the seasonal demands of Australian conditions. Available through authorised COX dealers.
