help. exmark viking hydro issues

i have a exmark viking hydro, it has been in storage. when i put it away last year i released the hydro pressure so i can push the mower around. took it out and started it tighten the hydro bolts and the left side is giving me issues. the right side is no problem the left side is varry slow and it pulls to the rightside i tried the tracking(didnt work). when u pull the levers back for reverse it work good just going forward. can there be air in the system? how do i get the air out? i tried loosening the bolt on the hydro pump and let a little fluid out, it got a little better but not like it was? thanks

Try tightening the spring on the idler pulley.

A little more specific, which idler pulley? If you suspect air on the system:
Raise back wheels off ground.
Set mower at about half throttle.
Slowly operate levers forwards to reverse 8 to 10 times.
Lower mower and test.

I open the reservoir as I can usually see the air bubbles stop, but I don't believe you have to.

Its been years since I owned my Viking. I had the same problem you were having and all I had to do was loosen the bolt on the tensioner pulley and pull it a little tighter with the chain and tighten it back up. This helped me out.

the tension pulley that makes the transmission belt tighter or looser. You can loosen the bolt and pull it tight with a chain connected to it.

This machine doesn't have a transmission. Are you talking about the pump drive belt idler pulley? The hydro pump drive belt idler pulley is tensioned by a spring.
