D140 Manual
The John Deere D140-48 is part of the Lawn mower & tractor test program at Consumer Reports. In our lab tests, Riding lawn mower & tractor models like the D140-48 are rated on multiple criteria, such as those listed below. Side discharging: A combination of evenness, which is how close the tractor or rider came to even, carpet-like mowing, and how evenly clippings were dispersed from the side-discharge chute.

Mulching: Reflects a combination of evenness, which is how close the tractor or rider came to even, carpet-like mowing, and how completely the mower distributed its clippings over the lawn's surface. Bagging: Denotes a combination of evenness, which is how close the tractor or rider came to even, carpet-like mowing, and a measurement of the effective capacity of the grass bag, determined when the bag was full or when the chute clogged and stopped collecting clippings. Drive type Drive type Categorized 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.
