I have an issue with my unknown year and model Montgomery Wards Hydrostatic 14 (that's what the decal once said). Everything ran pretty good on my beast until recently, when I had a drive shaft coupling issue, both ends cracked and eventually sheared from the shaft. I repaired the shaft and when installing, noticed that the hydro pump was basically falling off the adapter plate. Removed and resealed pump to adapter and then reinstalled the pump assembly, reattached hoses and drive shaft. I also drained and changed the filter for the transmission and filled. Now I come to my issue. After starting and placing in forward or reverse, the tractor does not move. I figured that I must have air in the system so I cycled the deck up and down control several times, shut the tractor down and let things settle out. I repeated the process a few times and still no forward or reverse. I did discover that when selecting forward or reverse with the raise or lower handle in either position and holding it in either position, I once again a able to go forward or reverse but when putting the raise or lower handle in the neutral position, its like I loose all pressure to the transmission.
This has me pretty much at a loss and if anyone has any info on this issue, your assistance would be appreciated.
