Taking loader off

Hi,
I have a 6245 with a Zetor loader fitted. Could some one tell me what the procedure is for taking the loader off its brackets for when its not needed on the tractor. I've tried dropping the legs down and taking the pins out of the brackets, but it seems to want to topple.

I havn't any experience of a Zetor loader, bit with our Trima loader you have to have a fork or bucket fitted to hold the front end on the ground. Then put the legs down,roll the bucket foreward until the pins are loose, remove the pins and then roll the bucket back and it should come free. then retract all the rams, stop the engine and work the levers all ways to release any pressure, remove pipes and back out.
Hope this helps, Dave
