Compare Mowers
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 each model is built for, from its duty class and key specs. This is a neutral reference — MowerFacts does not rank one model above another.
- Cox Push 18SL 18 in — residential: typical home lawns; 18-inch deck; gas powered
- Cox 21 in LawnMaster Self Propelled — residential: typical home lawns; 21-inch deck; gas powered
What’s different? The 4 differences that matter most, from the published figures.
- Push 18SL 18 in lists at A$399; 21 in LawnMaster Self Propelled lists at A$1,699, a A$1,300 difference. List price is the maker's own figure before tax, freight and dealer setup. Dealers set the final price.
- Push 18SL 18 in weighs 27 kg (60 lbs); 21 in LawnMaster Self Propelled weighs 52 kg (115 lbs), a 25 kg difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What Push 18SL 18 in's weight means for a trailer ›
- Push 18SL 18 in has a 139 cc (8.5 ci) engine; 21 in LawnMaster Self Propelled has a 224 cc (13.7 ci) engine, a 85 cc difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
- Push 18SL 18 in has a 457 mm (18 in) deck; 21 in LawnMaster Self Propelled has a 533 mm (21 in) deck, a 76 mm difference. Deck width sets how much grass each pass covers. Mowing time also depends on ground speed, turns and obstacles, so a wider deck alone does not fix the job's length. Time both decks on your own lawn ›
