  "textContent": "A neutral start switch arrangement is provided for a work vehicle (10) having a motor (16) driving a hydrostatic pump (28), the hydrostatic pump (28) driving a hydraulic motor (32) which drives a wheel (20, 22). The hydrostatic pump (28) typically has an input control shaft (115), the rotation of which moves the hydrostatic pump (28) from the neutral position to the forward or reverse drive position. A selectively rotatable control arm (114) is fixed to the input control shaft (115). A first arm (142) is mounted for rotation about the input control shaft axis. A second arm (152) is mounted for rotation about the input control shaft axis. The control arm (114) and the first and second arms (142, 152) are configured for the control arm (114) to be rotated from a neutral drive position to rotate the first arm (142) in a forward drive rotary direction or the second arm (152) in a second rotary direction corresponding to the reverse drive. A first leg (135) extends from the first arm (142) and a second leg (136) extends from the second arm (152), and a spring (138) is stretched between the first and second legs (135, 136). The spring (138) rotationally biases the first arm (142) and the second arm (152) toward each other and both into the neutral position. A neutral start switch (164) is mounted to the first arm (142) to orbit about the input control shaft axis with rotation of the control arm (114). The switch (164)has a push button (166) actuation portion that is arranged to be actuated by contact with the second arm (152) to change switch states when the control arm (114) is moved into the neutral position.",
