Re: 990 hydraulic issue

Cheers tomryall.
I noticed that there was a place for 3 balls when I last had it apart, but there were none.

Regards, Toby

Re: 990 hydraulic issue

Thank you for your patient explanations Ollek and tomryall, it is sincerely appreciated. If I repeat myself it is because I do not have a clear understanding of how this system on the 990 works. On reading your answers I now feel I have a clearer comprehension of the working of these hydraulics. I d...

Re: 990 hydraulic issue

1952Cropmaster: We're near Prince George B.C. Temporary fix: We piped the relief to an oil can in order to finish raking before the rain hit, success! So based on the advice received here my 990 is equipped with a double acting valve, our new rake has only one hydraulic line so when raising or lower...

Re: 990 hydraulic issue

Thanks guys. Good information but I'm still in the dark. Just need a quick fix to get the tractor back out in the field, we are close to finishing the hay harvest between rain showers. Two more hours of raking and the DB can sit waiting for a proper repair. Sounds like I need to figure a way to allo...

990 hydraulic issue

Hello, I received assistance here recently with some 3 point problems on my 990 (thanks again) That has been resolved, now we have another issue; What I assume is a relief mechanism attached to the front of the 'hydraulic block' Inside of this removable part are various parts, including a coil sprin...

Re: 990 trouble with 3 point

Hi Ollek, thank you for the clarification. I understand what you are saying, that it is actually only one circuit. The 990 has been a very good machine for us, we have maintained it well of course, but only minimal repairs have been required in 23 years of ownership. It was our sole tractor until 20...

Re: 990 trouble with 3 point

Problem I have is in transferring the pictures from incoming email to a format that I can access.
We are going to work on that.

Meanwhile, I installed the new hose, connecting the two circuits I had previously plugged;
three point works normally again.

Thank you for the advice.

Re: 990 trouble with 3 point

Cannot figure out how to post a picture, sorry. As a new member, I may be blocked? I took a couple pictures, had my wife email them to me, all good. I could probably email them to someone if necessary. I am assuming that the 3 point problem I have is as was suggested by ollek; that I inadvertently b...

990 trouble with 3 point

Hello, first post. Thanks for allowing me to join. I have a DB990, bought it in 1996, been using it on the farm ever since, although now we use it mainly as a raking tractor during hay season, plus a few other regular duties, such as running the 3 pt. mounted fertilizer spreader on the fields in the...
