Near Intersection of I-35 & I-90 Southern Mn. | Concerning the battery: This 440 may or may not have a 9 v battery in it. The older 440's used a battery to maintain the memory settings during periods of low voltage such as starting the tractor.
Unless the 440 is quite old it will not have a 9v battery in it. These newer 440's have a nonvolatile memory which means they will retain their settings without the need for a 9 v battery. These newer 440's often have the letters NVM on the front keypad. This stands for NonVolatile Memory.
I have seen a few of these NVM 440's where the customer was expecting that the box on the back should contain a 9v battery and have tried prying it open with a screwdriver.
There are a few hidden features that are useful in certain situations but you are probably not ready to hear about them yet. |
