Abstract

In a mower ( 10 ) driven by a pair of electric motors ( 15 ), a battery ( 16 ) for supplying electric power to the electric motors is positioned in a space surrounded by the electric motors and a chute ( 30 ) for forwarding grass clippings to a grass collection bag ( 23 ). The chute extends rearward with an upward slant, and is bent in side view in such a manner that a lower part has a steeper incline than an upper part thereof.

Claims (15)

1. A mower, comprising:

a main body;

a blade housing depending from the main body and having an open lower end;

at least one cutting blade supported in the blade housing in a rotatable manner in a horizontal plane;

an engine mounted on the main body for driving the cutting blade;

a grass collection bag attached to a rear end of the main body;

a chute extending in a fore and aft direction rearward with an upward slant to communicate an interior of the blade housing with an interior of the grass collection bag;

a pair of rear wheels provided in a rear part of the main body;

a pair of electric motors mounted in a rear part of the main body and connected to the respective rear wheels in a power transmitting relationship; and

a battery for supplying electric power to the electric motors and positioned under the chute in a space surrounded by the electric motors and the chute,

wherein the chute is bent in a middle part thereof corresponding to the position of the battery in side view such that a concave side thereof opposes the battery which is positioned centrally with respect to a lateral direction, and

wherein each side of the chute is in direct contact with a side of a corresponding one of the electric motors.

2. The mower according to claim 1 , wherein a lower part of the chute has a steeper incline than an upper part thereof.

3. The mower according to claim 1 , wherein the at least one cutting blade includes a pair of cutting blades positioned laterally one next to the other so as to be rotatable in opposite directions, and an inlet end of the chute is connected to a laterally central part of the blade housing.

4. The mower according to claim 1 , wherein the chute overlaps partially with the electric motors as seen in side view.
