4 . The golf vehicle of claim 1 , wherein the counterweight is slidable along the track system, and wherein adjusting the position of the counterweight includes lateral movement of the counterweight along the track system.

5 . The golf vehicle of claim 1 , wherein the counterweight is slidable along the track system, and wherein adjusting the position of the counterweight includes longitudinal movement of the counterweight along the track system.

6 . The golf vehicle of claim 1 , wherein the track system includes an X-Y table, wherein the counterweight is fixed to the X-Y table, and wherein adjusting the position of the counterweight includes controlling the actuator to manipulate the X-Y table to reposition the counterweight laterally and longitudinally in an X-Y plane.

7 . The golf vehicle of claim 1 , wherein the counterweight includes a plurality of weights, and wherein adjusting the position of the counterweight includes adjusting the position of at least one of the plurality of weights.

8 . The golf vehicle of claim 1 , wherein the IMU includes a gyroscope.

9 . The golf vehicle of claim 1 , wherein the actuator is hydraulically operated.

10 . The golf vehicle of claim 1 , wherein the actuator is electrically operated.

11 . The golf vehicle of claim 1 , wherein the control system is configured to control the actuator to adjust the position of the counterweight based on the angle of operation to counteract a tipping moment resulting from the angle of operation.

12 . A stability system for a vehicle, the stability system comprising:

a track system configured to couple to the vehicle;

a counterweight coupled to the track system;

an actuator configured to manipulate at least one of the counterweight or the track system to reposition the counterweight; and

a non-transitory computer-readable medium having instructions stored thereon that, when executed by one or more processors, cause the one or more processors to:

acquire telemetry data from an inertial measurement unit (IMU) for the vehicle;

determine an angle of operation of the vehicle based on the telemetry data; and

control the actuator to adjust a position of the counterweight based on the angle of operation of the vehicle to increase stability.

13 . The stability system of claim 12 , wherein the counterweight is slidable along the track system, wherein the track system is configured to extend laterally across the vehicle, and wherein adjusting the position of the counterweight includes lateral movement of the counterweight along the track system.

14 . The stability system of claim 12 , wherein the counterweight is slidable along the track system, wherein the track system is configured to extend longitudinally along the vehicle, and wherein adjusting the position of the counterweight includes longitudinal movement of the counterweight along the track system.

15 . The stability system of claim 12 , wherein the track system includes an X-Y table, wherein the counterweight is fixed to the X-Y table, and wherein adjusting the position of the counterweight includes controlling the actuator to manipulate the X-Y table to reposition the counterweight laterally and longitudinally in an X-Y plane.

16 . A method comprising:

acquiring telemetry data from an inertial measurement unit (IMU) of a vehicle;

determining an angle of operation of the vehicle based on the telemetry data; and

controlling an actuator to adjust a position of a counterweight of the vehicle based on the angle of operation of the vehicle to counteract a tipping moment resulting from the angle of operation.

17 . The method of claim 16 , wherein the counterweight and the actuator are part of a stability system of the vehicle, wherein the stability system further comprises a track system coupled to the vehicle, and wherein the counterweight is coupled to the track system.

18 . The method of claim 16 , wherein the counterweight includes one or more mower decks of the vehicle.

19 . The method of claim 16 , further comprising:

identifying information regarding a topography of a golf course on which the vehicle is in operation;

determining a predicted angle of operation based on the topography; and

controlling the actuator to adjust the position of the counterweight of the vehicle based on the predicted angle of operation to preemptively counteract the tipping moment.

20 . The method of claim 19 , wherein the topography is prestored and the information regarding the topography is determined based on a location of the vehicle, or wherein the method further comprises monitoring, using one or more sensors of the vehicle, the topography proximate the vehicle in real-time.
