Webrecently, the ls170 at our greenhouse has been having problems. My father says that in the morning, the machine starts up fine just about all of the time. Engine oil, hydraulic fluid, filter part numbers, service intervals and refill capacities Webthe ls170 is a real nice machine, i have 1,500 hours on mine and have never had an issue. Webdoes anyone have a clue what the problem could be? You can hear the electric fuel pump running with key on. I bought this unit new and has been my best one. Webhave a ls170 runs for about 15 mins then bogs down and dies. No waring lights or alarms come on. Have replaced fuel filters and air filters checked all.
