Hi ya all - I have a case 430 with a quickie loader.  The wieght on the rear arms of the tractor stay nice and solid and raised - but the loader seems to fall - and more recently it find it hard to lift.

What would be the first thing you check - it seems that even if I isolate the loader with the valve by the controls the loader seems to fall.

Hydraulic fluid level, don't top up and then recheck 24hrs later.  If the level has dropped you have a leak.

The pto engage lever had dropped its 'cable tie fix' and was on a half setting - doh - fixed it again but this time with two cable ties.

One of the reasons fork lift/telehandler hire places always leave their equipment in the 'up' position is to show there are no leaks with the hydraulics.
However if a pipe blows the arm will come down really fast so NEVER walk under the arms in an up position

Mine a bit of a pain in the bum going down all the time - but you dont have to get out when standing in it to paint the house - just start at the top and paint as it falls

for future reference it could also be failing seals in the hydraulic rams, allowing fluid to seep between one side and the other
