Agricat 454 no drive

So last week I carried out a service and replaced some hydraulic lines on my tractor, after I was finished, I started it and it fired straight away the hydraulics all work but it has no drive, I've tried everything I can think of and checked over everything but just can't get it to move. I can select gears, hi and low and the shuttle shift selects too is there something I am missing?
any help advise would be appreciated.
 
Hello Andrew welcome to YT! I can tell by several
phrases you used you are probably not from North
America. Best I can figure is that you are in Australia
because it looks like the Agircat tractors were
imported there. There is very little info on your tractor
on the web. I cannot even determine if it is a wheeled
tractor or a tracked machine. I believe it is the later
and is about 45 hp. Best I can determine is that you
possibly drained a gear case and you thought filling a
centralized hydraulic reservoir would refill it but it has
separate filler unknown to you. That is the best I can
do for you.
 

Thank you for your help. I can confirm that I filled the gearbox/diff with oil as well as the hydraulic fluid.

It has me perplexed as to what the cause is.

Nobody is doubting that you filled what you believe are all the places to fill with oil. Just suggesting that maybe you missed one that you're not aware of.

For the record I do not have any specific knowledge of your tractor, just general ideas. You mentioned a shuttle shift. It is probably hydraulically operated. In replacing whatever lines you replaced, you may have either crossed some lines up, OR "lost prime" to the shuttle, as in there is air in the line that operates the shuttle.
