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.
- FC3-261 uses a Kubota D1105 engine; F3690-SN uses a Kubota V1505 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.
- FC3-261 holds 30 L (7.9 gal) of fuel; F3690-SN holds 61 L (16.1 gal) of fuel, a 31 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.
- FC3-261 has a 26 hp engine; F3690-SN has a 36 hp engine, a 10 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.
- FC3-261 has a published top speed of 8.5 mph; F3690-SN has a published top speed of 12.4 mph, a 3.9 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- FC3-261 weighs 1,000 kg (2,205 lbs); F3690-SN weighs 765 kg (1,687 lbs), a 235 kg difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What FC3-261's weight means for a trailer ›
