My 170 has not been used for about a year, stored in a garage the whole time. When I try to start it with the foot clutch depressed and the transmission in either forward or reverse the tractor wants to move either forward or backwards. The free play on the rod connected to the clutch pedal is 5/8" which is called for in the service manual. Also after starting the tractor in neutral with the clutch pedal depressed the gears grind so I need to put it in gear before engaging the starter. The fluids are clean and full and do not have any bad odors. Any suggestions or corrective action would be appreciated because I have no access to a qualified mechanic. Thanks!
