The Toro GT550 garden tractor lawn mower is a very large and powerful machine. Sometimes the GT 550 is known as the Toro 522xi tractor lawnmower. The engine that powers this mower is a big one. It’s a Kohler Command engine. This engine is a twin cylinder model with overhead valves. The engine does not overheat thanks to an air cooling system. The total displacement of the engine comes to 0.674 liters. The output from the engine is 22 hp. This engine powers the wheels of the 522 XI through a hydrostatic transmission which gives it infinite speeds both traveling forwards and in reverse also.

Even though the Toro GT550 is clearly a very large tractor mower, it still has a reasonably small turning radius of just 20 inches. This is thanks to Smart Turn steering technology which slows the lawnmower down as you go into turns. The max speed of the GT 550 is very high at 12.1 kph (7.5 mph). The Toro 522xi also has a number of safety features built in. These include obvious ones like a driver detection system which cuts out the engine it the driver leaves the seat. There is also a ‘KeyChoice’ system which the driver must consciously engage if he/she wishes to mow their lawn while reversing.

The Toro GT550 has a range of different mowing decks that it’s compatible with. These are 3 Recycler decks that measure 44″, 48″ and 52″ in size. The Recycler mower decks turn the grass clippings into a fast decomposing mulch. The other mower decks that are compatible with the 522xi measure 42 inches, 44 inches, 48 inches, 52 inches and 60 inches in cutting width. When buying this lawnmower brand new, it comes with a full 2 year warranty to cover any problems you may have, while it also has a 5 year limited warranty. Other models similar to, but less powerful than this one include the Toro GT420 and the Toro GT430 lawnmowers.
