FYI, when you first get a SEE, there may be air in the cylinders which impairs the ability to achieve the locked position, or to tilt the backhoe back onto the tractor. Air is worked out of cylinders by working them back and forth, and this is best done by using full travel of the piston. Most people will find that the only way to achieve full travel on the main arm is to dig a 16' deep hole! And yes as previously stated pulling with a chainfall from the rops bar may be necessary to assist at first. Or, stop the tilt action halfway, and climb up and actuate the main arm out all the way and back a couple of times, this gets the air out of the pistons. Also, Until mine was fully bled out, I could only achieve the locked position by backing up a barn hill, raising the backhoe straight up in the air, spinning the unit all the way to the passenger side, and then bringing the whole backhoe back towards me, and reversing the lever just as it reached full travel. Yes you will blink as it seems to be heading straight for your face, and anything in the bucket will end up on your head! Be careful and have a spotter, and make sure the loader is firmly down on the front to stabilize the vehicle. You will know when you get all the air out when everything works smoothly, including tilting the folded loader back onto the tractor. Also freshly greasing all the fitting will help reduce the friction from causing binding. Visually checking the lock cylinders when releasing them is necessary as any side load will bind them, and you will not be able to tilt. Good luck.
