The motor assembly and the inverter are affixed to the chassis at a location where the motor assembly and the inverter are opposed to one another. The motor assembly includes an electric motor, a frame housing, and a motor bracket. The motor bracket is provided between the electric motor and the frame housing, and the electric motor is fixed to the frame housing via the motor bracket. The electric motor includes at least one electrical contact which is structured to be connected to electrical leads which extend between the electric motor and the inverter. The vehicle is an electric powered agricultural machine. ## Claims ### Claim 1 A vehicle comprising: a motor assembly; a chassis; an inverter; a transmission connected to the motor assembly; and an On board Battery Charger (OBC) which is affixed to the chassis; wherein the motor assembly and the inverter are affixed to the chassis at a location where the motor assembly and the inverter are opposed to one another; the motor assembly includes an electric motor, a frame housing, and a motor bracket; an output shaft of the electric motor is connected to the transmission such that rotation of the output shaft drives the transmission; the output shaft projects out from a front of the electric motor; the front of the electric motor opposes a rear of the vehicle; the chassis includes a pair of frame rails and a front wheel support frame; front wheels of the vehicle are provided on opposing ends of the front wheel support frame; the inverter is located between the motor assembly and the OBC; and all of the transmission, the motor assembly, the inverter, and the OBC are arranged along a straight line which extends from a front of the vehicle to the rear of the vehicle. ### Claim 2 (depends on 1) The vehicle according to claim 1, wherein the motor bracket is provided between the electric motor and the frame housing; and the electric motor is fixed to the frame housing via the motor bracket. ### Claim 3 (depends on 1) The vehicle according to claim 1, wherein the electric motor includes at least one electrical contact which is structured to be connected to electrical leads which extend between the electric motor and the inverter. ### Claim 4 (depends on 1) The vehicle according to claim 1, wherein the motor assembly is supported between the pair of frame rails. ### Claim 5 (depends on 4) The vehicle according to claim 4, wherein the motor assembly is fixed to the pair of frame rails via chassis attachment bolts. ### Claim 6 (depends on 5) The vehicle according to claim 5, wherein each of the chassis attachment bolts extends through a portion of the frame housing and into one of the pair of frame rails. ### Claim 7 (depends on 4) The vehicle according to claim 4, wherein the electric motor is located farther from the front of the vehicle than the inverter is. ### Claim 8 (depends on 7) The vehicle according to claim 7, wherein at least a portion of the electric motor is located to a rear of the front wheel support frame; and at least a portion of the inverter is located to a front of the front wheel support frame. ### Claim 9 (depends on 4) The vehicle according to claim 4, wherein the pair of frame rails extends from the front of the vehicle, past the front wheel support, frame, and to the motor assembly. ### Claim 10 (depends on 1) The vehicle according to claim 1, wherein the motor bracket is between the electric motor and the frame housing, and fixes the electric motor to the frame housing. ### Claim 11 (depends on 1) The vehicle according to claim 1, wherein the motor assembly is fixed to the pair of frame rails via chassis attachment bolts. ### Claim 12 (depends on 1) The vehicle according to claim 1, wherein the vehicle is an electric powered agricultural machine.
