I just (this saturday ) picked up a used JD 175 Hydro cheap at a garage sale. It runs and mows good but the neutral position is a little tricky, and it jumps forward when in neutral and the brake pedal has no effect so I assume they need adjusting. I searched 100 pages in this forum but did not find any info regarding my problem. I also searched the web for a few hours with no particular help. Anyone have ideas? I will be buying a manual but I need to mow now..........grass is growing..........its raining.........etc.
