Start with checking transmission lever and pedal positions to make certain something isn't in the wrong position, etc. Then fluid levels and filters/ screens. Go through the list from quickest/easiest to hardest items. I copied this list off another forum for basic ideas.

Basic hydrostat troubleshooting:

If The Machine Loses Power Or Won't Move In Either Direction
1)The oil may be low
2)The wrong kind of oil may have been used
3)The system may have an oil leak
4)There may be a restriction in the oil line
5)The filter may be plugged
6)The drive may be disconnected
7)The control linkage may not be functioning
8)The pump and motor may be damaged or worn out
9)The charge pressure may be too low
10)The check valves may be defective
11)The charge pump relief valve may be malfunctioning
12)The charge pump may be defective
13)The pump drive shaft may be binding
14)The system may have air in it
15)The pressure control valve may be stuck open
