What’s different? The 5 differences that matter most, from the published figures.
- 300R Zero Turn Mower uses a Briggs & Stratton® PXi SeriesTM engine; Spartan Shield-HD uses a Kawaski engine. The engine maker builds the engine; the mower maker chooses the model, rating and fit, so the badge alone does not settle output or longevity.
- 300R Zero Turn Mower holds 3 gal (11.4 L) of fuel; Spartan Shield-HD holds 5 gal (18.9 L) of fuel, a 2 gal 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.
- 300R Zero Turn Mower has a 12-gauge, Fabricated deck; Spartan Shield-HD has a 4" deck.
- 300R Zero Turn Mower weighs 544 lbs (246.8 kg); Spartan Shield-HD weighs 719 lbs (326.1 kg), a 175 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What 300R Zero Turn Mower's weight means for a trailer ›
- 300R Zero Turn Mower cuts from 1.5 in (38 mm) to 4.5 in (114 mm); Spartan Shield-HD cuts from 1 in (25 mm) to 5 in (127 mm). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.
