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.

Thanks

I have absolutely no experience with your tractor brand but it sounds like either you have some lines hooked up incorectly. without a picture of the setup and a schematic of how the hydraulics were originally run I couldnt be certain if I am even in the ballpark. The reason I would say lines is if your raise lower valve is in a movement position the fluid is flowing through the cylinder and then most likely bypassing to the trans and this does not happen in a correct hydraulic setup that I have seen.

Welcome to GTT. Is that a Gilson made tractor? Check our Manuals Section for the manuals that you need. I agree with Eric (above) but, also add that you may have the linkage out of adjustment. The manual should help you figure it out. Good Luck, Rick

Air in the tranny can be a real booger to get out.
Another possibility might be the tow valve has been opened?

Anyways, lots of guys have marveled at how hard it is to get all the air out. And don't forget to keep topping it off as you purge.

After checking to make certain that I did not get the hoses crossed (switched them around to check) and didn't get no response from either the lift up or down or any movement from the trans, so put them back and checked the fluid level, which was still full.  So back to the drawing board I went.  Decided that I would take another approach, if the pump was not getting a good prime, I would go right to the source.  There is a poppet port on the top of the pump, which I opened up and would slowly fill with fluid, while pulling the manual release bail for towing.  It was a slow process so jacked up the back end of the tractor enough to get some rotation on one of the tires.  Rotating the tire would turn the pump pistons and suck in fluid but had to be careful not to suck in more air.  Did this until I basically couldn't get it to suck in more fluid.  Put the poppet and spring back in place and tightened the plug up and fired the beast up, crossed my fingers and put it in reverse and away I went and just to make sure it was good to go gave it full throttle and took it for a victory lap, making sure that it would keep going even while raising and lowering my deck.

20160601_204922.jpg Here is a clearer pic of the numbers found on the engine.  Now for another question, can anyone tell me what model and year I have?   Am hoping to put this in the garage this fall and get it all broke down and cleaned up but that's my plan, just have to see what my other half has in store for me...

Once again, thanks for the assistance.

Good news that you got it purged. Perserverence is often the answer.
Looks like a fairly complete tractor. :thumbs:

The only thing I do not have pictured is the mower deck, didn't need it in the way while working on everything else.

With your sheet, and his engine model number the engine would have a 110 or 230 volt gear drive starter with alternator.

My mistake; I should have referred to the last line of my attachment, which displayed the birth date of the engine.

That's a Vickers hydro unit. Same as on an Allis 416H and others.
