1650 Won't stop

[go_aggies]

Hey guys I have a 1650 that has decided it no longer wants to stop even while in neutral. I plowed the other day for some tree rows and when I went to put the tractor in the shop I had to put it 3/4 of the way into reverse to get it to stop moving forward. I backed it out and hit the brake with no results. I had to move the hydro lever half way into forward to get it to stop. I changed the fluid and filter about two weeks ago so I tried the cam bracket adjustment that is described in the service manual. I did not have any luck in stopping forward movement. I inspected the check valves and they looked to be in working order. I swapped them around, and still had the same results. I took the check valves out of my 129 and put them in the 1650 and again I still have the same result. I thought that the filter may have gotten plugged so I replaced that and it didn't seem to have any effect.
As far as I can tell everything looks as it should. I am somewhat new to this so any advice would be greatly appreciated.

It's hard to tell from your picture, but the ball joint looks odd in the circled part....
Also, does your hydro control lever on the dash return to neutral when you apply the brake??

[go_aggies]

The lever does return to neutral when I press the brake in. I will get a better picture.

Here is a better picture of that ball joint.

Yeah, it looks ok in those pics.

You probably have a severe case of the hydro creep. You will need to jack up the rear end of your cub cadet, secure the front tires, loosen the two bolts on your unit and make an adjustment. A lot of guys use a small piece of wood and a rubber mallet to help in this matter. Just make sure that you are clear of the fan and make your adjustments when the tractor is not running. After each adjustment, restart the tractor and check your progress. This will likely take you a couple of attempts, so have patience. You will need to also make sure that the fuel tank has enough fuel in it and make sure that even though your cub is jacked up in the back, that your carb can still get fuel to the engine.

The hydro creep has been brought up here several times and should be easy to search for diagrams on it.

check for excess slop in the linkages,possible dash lever going to neutral but something between there and the trans got more wear ? did it happen all of a sudden prior to being ok ?

Check the linkage under the dash. The control lever/handle may be cracked or severely worn.

This did happen all of a sudden and I will check the linkage under the console tomorrow evening. I have jacked the rear end up and tried to adjust for the creep with no success. We have to go to K-State tomorrow to move all my son's stuff out of the dorm. I appreciate all of your help.

So I took the gas tank off and got a good look at all the linkages under the console. I ran the lever back and forth and did not see anything that looked worn out. I did notice that there is quite a bit of slop on the big spring between the two buttons in the trunion. I checked on the 129 and it seems to be similar. I am going to try to do the cam adjustment again tomorrow and see if I can get something to work. Thanks again for the assistance.
