3 Point Hitch "Accumulator

[Ijustwannaretire]

First post, first thread. Hopefully this is in the right forum, my apologies if not.

I have several Deere tractors from SCUTs to 5E series. Mostly used for snow removal, either sidewalks or snowblowing drives.

I have an older 4720 as well as a 5085E and 5100E that have Normand inverted snowblowers for doing driveways. Flat out the best way to driveways possible. But, I started having problems last year, first with the 5085 and now after 1 partial run the 5100 this year. We've been losing the 3 point ability to lift and hold the blowers up. On the 5085 we replaced the 3 point cylinder assembly the first time and then the rockshaft cracked. OR vice versa. The 3 point was sinking and then "jumping" back up and then finally failed completely. The 5100 was sinking\jumping and when we shut it off would fall to the ground within 5 seconds. I am pretty sure this is a result of riding up the roads with the blower hanging out the back and bouncing with no place for that energy to be dissipated except cylinders, seals, rockshaft, etc.

Which leads me to my question, I have been searching the interweb and can't find a nitrogen accumulator\ride control thing for 3 point hitches. Hoping someone here might have an idea or built one or something. I really wasn't planning on these major repairs this quick into ownership so I'm hoping to get some help.

Thanks

There are tractors that have such a system but I don't think your teori about why you have a leaking 3pt is correct, if it was you would see much more of this type of problems.

Talked to another contractor up in Kannada...Kubota has it as an option.

Agvg, any ideas why we're breaking stuff then? I need to get this fixed and then solved.

You haven't found the leak? Does these tractors have a shock valve to protect it if the pressure in the 3pt lifting cylinder gets to high?

 

[Ijustwannaretire]

The leaks have been a seal, a cylinder and a cracked rockshaft. Haven't gotten into the 5100 yet.

The 4720 was "bouncing" if we didn't lift it all the way. Had to adjust the cable a bit. I can't answer regarding the 5E series. Sorry.

Carry snowblowers are very common, and many runs endless hours of road driving with very heavy attachments in the 3pt with no issue, is this smaller JD a light chassis tractor?

 

[Agvg]

Oh, I miss read, those are quite HD tractors.

The E Series are the cheaper versions of this size tractor. The M and R series are more deluxe and of course significantly more money.

Well, it's very strange, thousands of these carry snowblowers all winter here and have never heard about any problems, what does JD say?
