Finally got to play with my new toy today 92 1020 gear drive trans with 1014 loader I used the loader for abit this morning worked like a charm decided I was gonna detach the loader this afternoon for easier access to the motor for oil change etc.. Got the loader off no problems at all unhooked the quick couplings and away I go I decided to use the box blade to straighten up some gravel in front of my shop before I put the tractor inside I've had the box blade on the tractor every since I got it it has held it up in the highest point of the hitch for two weeks without bleeding off so as I was leveling the gravel I went to raise the box and it would not raise I shut it off ASAP tried to see any issues but found none except the hitch will not raise at all ????? Any ideas ? Just to verify where do you check the hyd. Level ? Thanks in advance for you help
