The invention claimed is: 1. A lawn mower comprising: a frame including an engine mounting surface, and first and second vertical walls extending at least downwardly from the engine mounting surface, the engine mounting surface of the frame being provided at least partially between the first and second vertical walls of the frame; an engine for driving at least one cutting blade for cutting grass, the engine being mounted on the engine mounting surface of the frame; first and second hydraulic pumps and corresponding first and second wheel motors, the first wheel motor being controlled by the first hydraulic pump, and the second wheel motor being controlled by the second hydraulic pump; at least one hydraulic fluid hose extending between, and communicating with, the first hydraulic pump and the first wheel motor; and wherein the hydraulic fluid hose passes through first and second different spaced apart apertures defined in the vertical walls, in making its way from the first wheel motor to the first hydraulic pump, and wherein at least one of said apertures is located at an area where the engine mounting surface meets a corresponding one of the vertical walls so that the aperture is defined in both the engine mounting surface and the vertical wall. 2. The lawn mower of claim 1, wherein the vertical walls are sidewalls, and wherein an area at least partially surrounded by the engine mounting surface and the sidewalls is an interior of the frame; and starting at the first wheel motor, the hydraulic fluid hose passes through the first aperture that is defined in the first sidewall of the frame and proceeds into the interior of the frame, and then passes through the second aperture that is defined at least partially in the engine mounting surface of the frame and proceeds in an area exterior the frame toward the first pump. 3. The lawn mower of claim 1, wherein the vertical walls are sidewalls, and wherein the first aperture is defined in the first sidewall of the frame, and the second aperture is defined in the first sidewall and/or in the engine mounting surface of the frame. 4. The lawn mower of claim 1, wherein first and second hydraulic fluid hoses extend between the first hydraulic pump and the first wheel motor, and wherein the first and second hydraulic hoses each pass through the first and second apertures defined in the vertical walls in making their way from the first wheel motor to the first hydraulic pump. 5. The lawn mower of claim 4, further comprising third and fourth hydraulic hoses that extend between the second hydraulic pump and the second wheel motor, and wherein the third and fourth hydraulic hoses each pass through third and fourth spaced apart apertures defined in the vertical walls in making their way from the second wheel motor to the second hydraulic pump, and wherein the first and third apertures are defined in the first and second vertical walls of the frame, respectively. 6. A lawn mower comprising: a frame including an engine mounting surface, and first and second sidewalls extending at least downwardly from the engine mounting surface, the engine mounting surface of the frame being provided at least partially between the first and second sidewalls of the frame; an engine for driving at least one cutting blade for cutting grass, the engine being mounted on the engine mounting surface of the frame; first and second hydraulic pumps and corresponding first and second wheel motors, the first wheel motor being controlled by the first hydraulic pump, and the second wheel motor being controlled by the second hydraulic pump; at least one hydraulic fluid hose extending between, and communicating with, the first hydraulic pump and the first wheel motor; and wherein the hydraulic fluid hose passes through first and second different spaced apart apertures defined in the frame, in making its way from the first wheel motor to the first hydraulic pump; and wherein the lawn mower further comprises a wheel motor support that supports the first wheel motor and is pivotally mounted to an exterior surface of the first sidewall of the frame, so that pivoting of the wheel motor support causes movement of the first wheel motor so that the height of a drive wheel attached to the first wheel motor can be adjusted relative to the frame whereby a cutting height of the mower can be adjusted. 7. A lawn mower comprising: a frame including an engine mounting surface, and first and second sidewalls extending at least downwardly from the engine mounting surface, the engine mounting surface of the frame being provided at least partially between the first and second sidewalls of the frame; an engine for driving at least one cutting blade for cutting grass, the engine being mounted on the engine mounting surface of the frame; first and second hydraulic pumps and corresponding first and second wheel motors, the first wheel motor being controlled by the first hydraulic pump, and the second wheel motor being controlled by the second hydraulic pump; at least one hydraulic fluid hose extending between, and communicating with, the first hydraulic pump and the first wheel motor; wherein the hydraulic fluid hose passes through first and second different spaced apart apertures defined in the frame, in making its way from the first wheel motor to the first hydraulic pump; and wherein the first wheel motor is supported by a first wheel motor support, the first wheel motor support being pivotally mounted to an exterior surface of the first sidewall of the frame, and wherein pivoting of the first wheel motor support causes movement of the first wheel motor so that the height of a drive wheel attached to the first wheel motor can be adjusted relative to the frame so that a cutting height of the mower can be adjusted. 8. The lawn mower of claim 7, wherein an aperture is defined in the first sidewall of the frame, and wherein the first wheel motor is at least partially located in said aperture defined in the first sidewall of the frame. 9. The lawn mower of claim 7, wherein the frame further includes first and second fenders made of sheet metal, the first and second fenders being provided at least partially over first and second drive wheels of the mower.
