I am ready to make a commitment to Mark for one. Possibly if others do so also, he might get a better idea of how many people want and he could start a "notify" list. Definitely put me down for a Cat 1 link..... thanks .......

</font><font color="blue" class="small">( John Mc,
There's about an inch of drop/minute at the back end of the brushhog. I didn't measure it, but as I sat in the tractor seat, I could see it slowly dropping.
Do you have any check valves in your 3PH system? )</font>
Sorry it took me so long to respond. I was away from home for a couple of weeks, and I'm just catching up.
I do not have check valves on my TNT set-up. I get about an inch of drop in about15 minutes, measured at the rear of my brushhog from the hydraulic toplink leaking down. Since I generally don't use the toplink to support the mower when mowing, this hasn't been a problem (mower rests on the rear wheel). As fast as yours is dropping, you've definitely got some problem with the set-up. My guess is a leak in the system (any puddles or drips you can see?) or a bad seal in the cylinder.
It has been a pain in the neck on the side link. It leaks down and I forget to adjust it, then I'm mowing lopsided, and eventually dragging the side of the mower deck on the ground. If I had it to do over again, I'd get the cylinders with the check valves.

Check valves are available as separate units which can be installed in an existing circuit. That is something I would like to do for a few functions on my BackHoe attachment and Loader, as well as the hydraulic top link.
I've made a few phone calls, but am still searching.

Let us know what you find. I may be looking for the same thing. I'm still thinking I've got a seal problem in my cylinders which I've got to deal with, but if that doesn't solve the problem, I'll start looking at check valves and high-end hydraulic hoses.

Re: DO I NEED A CHECK VALVE ON MY HYDRAULIC TOP LI
With my very limited hydraulic knowledge, but after a great deal of reasearch, I have learned that you need to get ( 2 ) pilot operated check valves. These valves allow fluid to pass when pressure is applied to opposite end of the piston. They have a third port that in-effect gets short circuited to the other inlet ( outlet ). You will see some cylinders with the valves installed and a small tube ( 1/4" ) between the the two valves. They are available, but I never bought them. Once I got the air out of the cyclinder its been fine.

Junkman,
A new shipment hydraulic toplinks is to arrive today 12-20-03 at the port. We hope to have them through customs and on the way to customers soon. There is a good supply but if the US $ does not get any stronger, we are faced with either raising prices or going to a non-European country for production. We have not raised the prices yet. We are taking orders now at the old stronger US$ prices.
Thanks for your support and understanding on this stocking situation .

Re: DO I NEED A CHECK VALVE ON MY HYDRAULIC TOP LI
Good old US Customs and the Holidays. Today Jan.31,04 I have the Hyd. toplinks, with check valves, in my hands and will start shipping Monday. The Government only gets in a hurry if you owe them money. If you want the full bore Top & Tilt the Integration Engineering system is the best value out there.

Re: DO I NEED A CHECK VALVE ON MY HYDRAULIC TOP LI
CCI.... You have muddied the waters for me...... I want a top link that is adjustable, and you say that </font><font color="blue" class="small">( If you want the full bore Top & Tilt the Integration Engineering system is the best value out there. )</font> Since the Top & Tilt by Integration hasn't released any information, how am I to make an intelligent decision to go with theirs or your valve? /forums/images/graemlins/confused.gif I have send a couple of e mails to Jim, but no reply. Now, can you help me with this dilemma? Buy yours while it is available or wait till Jim announces the cost and benefit of his unit.....

Re: DO I NEED A CHECK VALVE ON MY HYDRAULIC TOP LI
Junkman,
I have seen the Top and Tilt and it is very nice. The Top & Tilt has a hydraulic top link with check valve and a Hydraulic side link with check valve. The top and tilt will require use of your tractor's hydraulic valves or can be controlled with a power beyond joy stick type valve. There is more money involved in the top and tilt system. Come to the National Machinery Show and see it or wait for the pictures.
