Cub Cadet LTX1050 forward delay/jump

[Dukes7779]

A couple days ago I posted this in the Cub Cadet L&G section with many views and no replies so I知 also posting here.
A couple months ago my drive belt came loose and shredded my hydrostatic fan on my LTX1050. Fixed easy enough (with help of PB Blaster). However, now I am having problems going forward. When I press the forward pedal there is a delay of a couple seconds before the machine will go forward and when it does it sort of jumps forward but then rides fine as long as I maintain a certain speed. It almost feels like a spring is loose and takes a second to get enough tension to engage the transmission but the pedal has to be pushed forward enough to get it going that it is low-mid speed position which is what I believe causes it to jump forward. Reverse is absolutely fine though, which adds to my assumption of a spring problem on the forward mechanism. Could it be a linkage problem though with these symptoms? Did I screw something up when I dropped the transaxle to replace the fan? Anyone experience this?

Thanks!

Welcome to the TBN. I'm unsure where the PB comes in here. Maybe you could post the chassis number from below the seat.

PB Blaster helped me remove the nut to replace the hydro fan is all.
Model number is 13WQ91AP009

So you could be on the right track. When you dropped the t/a, was the linkage removed or could it have been bent? Here's an IPL which helps on spring placement etc. Cub Cadet LTX1KW (13WQ91AP9, 13WQ91AP, 13WQ91AP56, 13WQ91AP21, 13AQ91AP9) - Cub Cadet Lawn Tractor (212) Drive System (Hydro-Gear) Diagram and Parts List | PartsTree.com

Thanks for the link! I suppose a linkage could have been bent but don稚 see anything obvious. And I imagine that would shorten the pull rather than lengthen it. I値l recheck those too though

My aunt has that same mower, deck belt shredded and that was a pain to change and get back on correctly.
Then the drive belt jumped the trans pulley and destroyed the fan. I cant see how that occurred with the guides as close as they are. Will hopefully have time to replace this week.
Hope you figure this out in case I run into the same problem. Did you drop the trans or work in it through the battery box.

I dropped the transaxle to do it.

Have you checked to see if the new belt is routed correctly? I think there is a tensioner/idler under there. Correct belt length?

I have checked the belt route and that is fine. I did not have to replace the belt so it is the factory installed belt. I will check for a tension/idler though, thanks!
