| 摘要 |
The present walk-behind, self-propelled motor has two hydraulic motors whose rotors are directly connected to the hubs of respective drive wheels on opposite sides of the mower deck toward the rear. These motors are driven by respective pumps, each of which has its direction and rate of fluid displacement controlled by a handle mechanism on the upper end of a corresponding fixed handle extending up from the deck at the rear. Each handle mechanism has a pivoted handle coating with a locking lever to set the corresponding pump in neutral, forward or reverse. An internal combustion engine drives both pumps as well as cutting blades located below the mower deck toward the front. Vertically pivoted wheels are located in front of the mower deck.
