Prices are the recommended retail prices published by each manufacturer’s Australian site, in AUD, as read on the date shown on each model’s page; dealers set the final price.
A side-by-side reference of each model's stated specifications. MowerFacts doesn’t give opinions: where a published, spec-derived rule can separate machines we mark a Data Pick and show the rule; here, read the values and decide what fits your needs.

What’s different? The 5 differences that matter most, from the published figures.
- ZD1221R-60 has a 2-HST w/ Gear reduction transmission; Rogue Rear Discharge has a Hydro-Gear 16cc Pump; Parker 18ci Wheel Motors transmission. The transmission grade tracks duty rating and speed. Grade names are each maker's own and are not comparable across brands.
- ZD1221R-60 has a Kubota ProDeck deck; Rogue Rear Discharge has a 3 Gauge / 6mm deck.
- ZD1221R-60 has a 29.1 hp engine; Rogue Rear Discharge has a 35 hp engine, a 5.9 hp difference. Published horsepower is the maker's rating at a stated engine speed. It is a different measure from displacement, and two engines of equal rating can pull differently.
- ZD1221R-60 has a published top speed of 10.6 mph; Rogue Rear Discharge has a published top speed of 13 mph, a 2.4 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- ZD1221R-60 cuts from 25 mm (1 in) to 127 mm (5 in); Rogue Rear Discharge cuts from 50 mm (2 in) to 127 mm (5 in). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.
