z5000 toro zero turn will not move forward or back

[7394]

How old is the machine ? Has the build date listed back behind the battery on mine.

But if you bought it new or from someone, that date it was first bought starts the 3 year warranty..

waiting to here back from toro to see if they are going to cover it ..it being the question ..will be my last opt if i cant fig it out was hoping for a somewhat easy fix. hate for it to be a major one with the mower being so new .makes my confidence in the brand low for the long haul. im starting to think maybe i should of spent a few more $ and stuck with husqavarna.

From the top.
1) some thing made the belt jump off. the pump belts are generally very tight and seldom jump off unless you get a reasonable lump of branch stuck up there.
From the parts diagram it appears the pump drive belt goes through a tensioning clutch and there are no belt keepers.
Double check the belt routing. make sure it goes really tight when the clutch is engaged and then really loose when disengaged

2) when the motors are in the neutral position most pumps ( not familiar with this particulear one ) simply route the high pressure oil strait back to the reseviour so there is very little resistance to the pulley turning.
As ther is not much resistance from the pullys they will happily turn even if broken or loose. But breaking them both simultaneously is about as likely as winning the lottery.

3) while 1 motor / pump unit might fail, having both of then fail does not sound right.
These Hydro units are tough as nails and while one might fail catastrophically I could not see both of them coming to grief at the same time.
Not impossible but highly unlikely.

4) neither unit working would make me look towards the drive pulley or tension spring / clutch set up.

5) If you can turn the wheels easily then the bypass valve is probably open ( see instruction for pushing mower )

ty sir for the info ..and you are right it was the drive belt . I found that on the schematic i found at the toro site of that belt that even though it looked like i had it on right that in fact i did not . i dont know how to put a pic of it here to explain it but it was like the picture was upside down and the belt was not around the drive pulley enough to make it work right . the belt needed to be wrapped at least half way around the drive belt to make it work the way it should. i had it only on the back side of that pulley going to ea. of the hydro pulleys then to the tension er pulleys. anyway its back on right and working well the belt was still in great shape so no parts needed was a great learning exp. thanks to you and all the others who commented on this thank you all..Bob

Starting a new thread would of been better than tagging onto a thread from 2014 but to answer your question, release the hydrostat bypasses, and the brakes and see if it will role. Sounds like the brakes are not releasing.
