OK, confirmed my Bobcat is a G series. Serial number is 512261407. It has no Seat Sensor. When the glow plugs don't go on there is no error code but it is really a non issue, I just turn the key off and on and they work. The big problem is every once in a while the brakes lock up unexpectedly. You have to hit the Green operator button again and everything is a go. Does it more when it is cold. Kinda dangerous so would like to get it fixed.
