Note:
3020,
The hydrostat used on the Sand Pro 2020,
and 5020 are very similar. Due to different pump
attachment to the engine, the location of the control
shaft is different. On the Sand Pro 2020 and 3020, the
control shaft is on the implement relief valve (30 and 31)
side of the hydrostat. On the Sand Pro 5020, the control
shaft is on the charge relief valve (41 and 42) side.
