Looking for when the oil and transmission should be changed on Lt

Hey,

Many manufactures recommend a engine oil change every 50hrs more often in extreme conditions,

Most transmissions are sealed units if this is the case company's recommend not to touch these,

If you have a hydrostatic drive or a Zero turn unit with twin hydrostatic drives the transmission oil must be changed every 500 hours or every year whichever comes first as the hydraulic oil brakes down in time, also at these intervals the hydro oil filter must also be changed...
