What’s different? The 5 differences that matter most, from the published figures.
- 52 in Z Master 4000 Series has Rubber discharge; Z554L has Collect/Mulch/Side discharge discharge.
- 52 in Z Master 4000 Series holds 37.9 L (10 gal) of fuel; Z554L holds 45.4 L (12 gal) of fuel, a 7.5 L difference. Tank size bounds how long a machine runs between stops. Consumption varies with engine, load and speed, so hours per tank are not fixed.
- 52 in Z Master 4000 Series has a 25.5 hp engine; Z554L has a 27 hp engine, a 1.5 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.
- 52 in Z Master 4000 Series has a 1,321 mm (52 in) deck; Z554L has a 1,372 mm (54 in) deck, a 51 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 ›
- 52 in Z Master 4000 Series weighs 538.4 kg (1,187 lbs); Z554L weighs 551.1 kg (1,215 lbs), a 12.7 kg difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What 52 in Z Master 4000 Series's weight means for a trailer ›
