What’s different? The 5 differences that matter most, from the published figures.
- Stander LG 61 FX850E has a Floating-side discharge deck; Spartan RT-Pro has a 6" Deep, Reinforced 7 Gauge Full-Floating Deck deck.
- Stander LG 61 FX850E cuts from 1.7 in (44 mm) to 5.7 in (146 mm); Spartan RT-Pro cuts from 1.5 in (38 mm) to 4.8 in (121 mm). The cut-height range is the shortest and tallest cut the deck offers. Most lawns are kept well inside it.
- Stander LG 61 FX850E has a 27 hp engine; Spartan RT-Pro has a 24 hp engine, a 3 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.
- Stander LG 61 FX850E has a published top speed of 12.5 mph; Spartan RT-Pro has a published top speed of 11 mph, a 1.5 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- Stander LG 61 FX850E holds 11 gal (41.6 L) of fuel; Spartan RT-Pro holds 9.5 gal (36 L) of fuel, a 1.5 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.
