Here is the toplink. I will try to post more.

This is the adapter I was talking about

Will this work on the BX2200? I Had to cut the screw threads on the one that came with the tractor to be able to shorten it another inch. I am wanting to use the box blade to dig a little deeper with the teeth. I can only get very little of the teeth biting into the ground because the top link is too long. I will go look at their web page if they have one.

How was it to actually use the hyd toplink? I watched the video, but it's always good to hear from someone who's actually used one.

I don't know anything about the bx2200. Although as I pointed out that adapter comes in various lengths. I am confused on what you want to know mikepa. You raise implement open valve to lengthen shaft (toplink) close valve to lock the desired length. Lower implement to ground open valve creep forward this forces shaft closed lock valve in desired length.

Twanger, I was contemplating getting rear hydraulics installed in order to have a hyd toplink (I don't need Tilt) and was wondering whether you think this device is almost as good?

I figure this attachment from Jiffy will cost about $275, ($245 + shipping) versus about $400 ($250 just for the rear hyd parts, plus a cylinder, plus hoses, etc.).

Mike it works pretty slick. You do not have to get of your tractor to adjust the toplink just flip the valve. You can remote mount the valve to the rops if desired. The only thing is it is not powered.

I am thinking of building one of these toplinks. We have been referring to the "accumulator" which is plumbed to the toplink. I think that is the correct term based on what I have read on this website. <A target="_blank" HREF=http://www.accumulator.co.jp/what.html>http://www.accumulator.co.jp/what.html</A> Can some of you hydraulic types take a look at this website to confirm we are correct.

Here's an Australian version of the hydraulic toplink <A target="_blank" HREF=http://www.bareco.com.au/files/hydraul/hydraul2001/hy22.htm>http://www.bareco.com.au/files/hydraul/hydraul2001/hy22.htm</A>
looks like they only make cat 2 & 3, but still a very interesting site.
They also make and sell remote hydraulic kits for ford & MF tractors, to use the onboard hydraulics for other impliments.

Mike. I don't think it really is an accumulator. I think it is only a fluid storage area. The picture of the square one looks like there may be either a breather or fill plug on the top. Maybe it is just a fill plug, but a square shape will not hold much pressure without distorting and becoming a round shape. If it was an accumulator the pressure in it would push the piston when the valve was turned and that is not how it is described to operate. The two sides of the cylinder have different volumes because of the rod and that is why fluid storage is required. There is no reason that the fluid storage area would need to be under pressure except maybe to fill the cylinder a little faster.

It looks like the more difficult thing to obtain would be the valve. The valve appears to have 3 connections, one for each end of the cylinder and one for the fluid storage. I would suspect that in the closed position all 3 connections are closed and in the open position all 3 are open. The valve would need to be able to withstand the pressure created from the weight of the 3pt implement and any shock loads. I would think this would need to be a high pressure valve.

Andy,

I went to a shop that specializes in hydraulics and inquired about the accumulator. He said an accumulator would do what I am asking of it but he is not sure if what is on the "self contained hydraulic toplink" is an accumulator.

I am going to ask Craig to see if there is a part number and or manufacturer on the unit he has.

You are correct that the valve is kinda funky. It has a somewhat sloppy weld job on the side of the valve that connects to the tank. The tank is a sealed box that does have a plug in the top.

A question for when this is being used with a quick-hitch:

When I drop one implement, then connect with another, I invariably have to adjust the length of the top link in order to hook up.

It seems that I would have to get off the tractor, open the valve, then manually push or pull the hydraulic top link to the correct length.

Is this correct?

Twanger · Apr 30, 2002

I don't necessarily think so. You could back into the implement open valve and compress the cylinder, or leave the implement on and lengthen the cylinder before you switch. I have manually opened and closed the cylinder and it is very easy to move.
