The Ryobi R48110 (Electric) is part of the Lawn mower & tractor
test program at Consumer Reports. In our lab tests, Lawn mower & tractor
models like the R48110 (Electric) are rated on multiple criteria, such as those listed below.
Side discharging: How far and evenly clippings were dispersed from the discharge chute.
Mulching: Reflects how fine the clippings are and how completely the mower distributed its clippings over the lawn's surface.
Bagging: Denotes how much clippings the bag held before it filled or the chute clogged.
Cuts in reverse
Cuts in reverseSome tractors don't let you cut grass in reverse. While a good safety feature, this can also be inconvenient in tight areas. Certain models instead require you to engage an override switch.
Cruise controlLets the tractor's driver maintain a constant speed without using the foot pedal.
Washout portAccepts a hose for cleaning the underside of the deck more easily than from above. Be sure to allow the underside to air-dry before stowing the machine.
Power steeringHydraulic or electric boost to reduce force required to turn the steering wheel.
Deck sizeThe manufacturer's claimed cutting width, or swath, in inches. Rear-engine riding mowers are about 30 inches, and lawn tractors are about 38 to 48 inches or more. Mowers with larger decks take up more storage space, but cut proportionally faster and therefore reduce cutting time.
Engine powerThe manufacturer's claimed horsepower for the engine. All other factors being equal, an engine with more power will be able to handle tougher jobs (such as tall grass) without bogging down.
Engine manufacturerThe brand of engine on the tractor or rider.
Drive typeCategorized by the drive system (engine and transmission), which controls a tractor's direction and ground speed. Hydrostatic-drive tractors let you smoothly increase or decrease ground speed infinitely with a lever or foot pedal. Gear-drive tractors involve shifting, clutching, and a distinct set of speed ranges. Tight-turning, "zero-turn-radius" riders use a dual hydrostatic-drive system to infinitely vary ground speed and allow a narrow turn radius by varying power to each rear wheel independently. Pedal-drive tractors use a continuously variable transmission (CVT) to vary ground speed depending on how hard the drive pedal is pressed. Pedal-drive tractors do not have a hydraulic transmission like hydrostatic models, and they require shifting when changing between forward and reverse. Manual-drive tractors are similar in design to pedal-drive models except that the pedal is replaced with a detented lever that only allows several discrete ground speeds. They function like a gear drive tractor, but instead of a geared transmission, they incorporate a CVT. Rear-engine riders are smaller than tractors and have a rear-mounted engine.
Number of cylinders
Number of cylindersThe number of gasoline combustion cylinders in the engine.
Forward speedsAll tractors with gear-drive transmissions have multiple forward speeds, usually five or six. Tractors with hydrostatic transmissions have infinitely variable forward speeds controlled by the operator.
WarrantyThe length of time the lawn mower is covered by its manufacturer for defects or repairs.
