1. An operating method for a slow-speed, solar powered programmable lawn mower which comprises:

  • precharging the battery using solar energy,positioning the mower at a user-determined reference point, engaging program recording, and moving the mower around the lawn as desired so that the unit records the specific relative turn rates for the reference wheels over exact incremental distances, with the user ultimately returning to the original reference point and terminating the recording,executing the recorded program in an indefinite loop, such that the processor powers the two variable drive motors in order to produce an identical relative turn rate over exact incremental distances in and between the two trailing reference wheels,using lightweight materials, solar cell power, and minimal electric current,powering the variable motors, the processor, regulator(s), and constant speed motor for the reciprocating cutting head, which moves slowly but inexorably against a grass-blade tongue guide to cut grass in a safer manner than traditional highpowered mower designs,intermittently self-checking against the stationary reference point by means of at least two wire leads at that point, making connection with contact points on a sensor plate, and thereafter reorienting to achieve the original orientation, then continuing program loop,powering down to preserve memory and processing function overnight or in long shady conditions as needed,optionally recharging battery at the stationary reference point for shady/nighttime use by means of low voltage input
