Hydraulic Quick Coupler- How it works

This is a quick video showing how the hydraulic quick coupler on the John Deere 850D-LC works. Here you can see we change buckets from the 8yd digging bucket to the 5yd straight edge bucket.

Do you ever have the problem of rocks and shit getting inside your quick coupler and jamming it up? One of the guys I work with broke the cylinder in the coupler and I've been finding a that I also get a lot of rocks inside the unit and it takes a bunch of extra time to clear the crap out. ??

@ajdaigneau Not so much rocks as these couplers do have guards over them to prevent it. On the other hand we've had mud and dirt get in there and freeze in the winter and be a royal pain in the ass.

thats true i like any hitch thats stops you get in an out to change buckets is agood thing i read your comment on the volvo have you driven an volvo machine ?

[vantagetes]

@533nick Yes I (Alex) have. I'm sure they are a fine machine for over in Europe but here they aren't quite what we are used to. I grew up with John Deere hoes and I mean actual Deere hoes before Hitachi. When you climb in a Volvo it feels cheap, they cater to the European market with being compact, light and fuel efficient. Unfortunately people here like having power. I like a hoe with grunt. Ever tried snapping up 3ft of solid frost slabs with a hoe that couldn't snap up 6" of concrete?

@vantagetes I would have been more concered by being called "AMERICAN"?

@t0lwers So how are we still in the stone age? Seems like awful big words coming from a rock truck driver in Sweden.

@t0lwers Using a tilt rotator on a road job? Well we do have graders and trim dozers for that. I see the benefits of having the rotate feature, but at the same time how often have I felt the need to spin that fucker around 360 degrees? I can do it on a grader doesn't mean I use it there either. Many people around here do have rotating couplers but you also have to remember thats generally a stage in the development Jason and I aren't around for.

@vantagetes I wasn't really referring to this Deere with hydraulic coupler. I've been watching your videos and yeah, I understand you guys. You have huge construction sites with lots and lots of earth/rocks to move, of course you have big machinery for that. But for smaller things? Things like a road in a residential area, land planning and yeah, smaller sites? Why don't you use a Tiltrotator? In Scandinavia it's as common as bacon, everyone eats bacon. You guys have a tiltbucket at your best?

@533nick I also like the engcon coupler, WBM couplers, Dromone's, Wood's and Case and JD make nice couplers. Everyone has the unit they prefer so I'll say any coupler that keeps me from pulling 2 pins to change a bucket is the best. Except JCB.... we all agree we don't like JCB haha.

[vantagetes]

@533nick The easier one to use doesn't make it the best. I have used JRB, Geith and H&H pin grabbers and liked them all. I like the price of the Geith and the safety locks are nice on them. The H&H integrates well into a machine that was not originally setup to have a hyd. coupler and JRB makes a great coupler that is easily serviceable, great quality and outlasts the machine you bolt it to. Each company has its advantages and disadvantages. There will never be a clear winner in best hitch.

[533nick]

So tell me which is the best we have use them all and the miller is the easier one to use

[vantagetes]

@533nick Says who? I have used the Cat pin grabbers which are Miller Bug's and trust me they aren't the best. They are nice but I have used better.
