a point to remember about hydrostatic transmissions. many must be checked for oil level when the unit is idling usually in neutral or park some only read accurate when the unit is at operating temp. any i have had stuff to do with have had marks for cold and hot on the dip stick. as always read the flaming manual.

engines made by AH MacDonald & Co had on the brass engine plaque in large type "read instruction book" hence they are sometimes called "read" engines the makers name was in much smaller type.

I have a LD7 Scoupmobile. It had similar symptoms to yours . Being unable to find a level plug , I pumped about 20 litres of TOU in through a bung in the top of the T/C. This solved the problem . How easy is that??? Dan .
