Default Need help with 455 Quick Hitch Adjustment

Hi All,

Needed a resource for an issue I'm having, found this forum, thought I'd give it a try. Have a JD455 with a JD Quick Hitch (4 way hydraulics) with a JD 54" blade.

During the last few days of plowing snow the left angling of the blade has been reducing a good amount with the right angling seeming to become more pronounced. Vertical hydraulics are working fine.

I have the original manuals for everything, but didn't readily find mention of how to correct this.

Thanks for any help any of you can offer. On a separate note, I think I'll be looking to purchase a snow thrower implement for the quick hitch next season. Any recommendations for where to purchase something used?

Thanks again!

I had a quickhitch with a blade on a 445 and found that snow would pack and freeze around the angling cylinder limiting the travel of the blade. That shouldn't affect the angling to the right though. The only other thing I can think of is the diverter valve, or lockout valve, that limits hydraulic fluid flow to the cylinder that raises and lowers the mower deck. If it isn't closed all the way it could affect the speed of the angling cylinder.

455, Welcome to the forum. Need more info on whats going on with the blade. Is it not moving far enough to the left? Or not staying there?

The same thing happened to me last year... do not and i repeat do not force it. the line that is connected to the angling has a 90 degree elbow that broke cause i had the same thing happen... your best bet is to get a little heater and heat the snow up and let it melt. what happens is the snow gets compacted and it wont let it get to full angle

Also check your hydraulic fittings on the cylinder as they may have loosed up and be catching on the frame. slkpk

Thanks for your feedback everyone. Snow had frozen in the angling hydraulic relief. Removed it and all's well again. Luckily, the elbow hardware wasnt damaged. Got some before and after pics I'll upload later of this. Maybe that'll be helpful for someone else down the line!
