In Reply to: Re: Front wheel locks up and now Koyker FEL valve sticks bad posted by Al on Wednesday, February 06, 2008:
Al,
Thanks for the help. The problem is internal. I am meticulous with maintenance (probably overly preventive). I am certified and mechanically savvy on varied types of heavy equipment/machinery from excavators to small bush hogs (Gratis military). The problem is an internal valve issue. Keeping my hand on the valve is not realistic unless the only place I operated the tractor was on a flat surface in strictly a forward and backward operation.
For the forum: Having a sticking hydraulic valve needs to be repaired ASAP. It will kill you or someone else. Finesse and ability to panic check is removed. If you find yourself in a pickle (off camber, tipping, traveling and floating the bucket for dress, managing round bales or heavy work like gravel or clay) and the lever sticks, in your haste to either disengage power, change direction, stop, manage the steering wheel etc…the bucket or arm will continue operating in its stuck position. Mine happened to be while loading gravel in my pickup. While traveling up to the truck and lifting the bucket, my lever stuck in the up position. It almost dumped the load in my lap. The military utilizes hydraulic power on a myriad of machines because it is easy to maintain, repair and extremely efficient power with incredible energy. Operating high torque or high energy machinery with unreliable controls can easily trap, sever limbs, or kill you or someone else. It is not worth the risk. Sorry for the tirade. I had a cousin get caught in a baler and he could have easily ejected had he not “rigged” a sticking safety bale switch. Stupid, stupid, stupid……. Fix the damn valves, switches and levers most tick!
