Ron, my trailer has DA cylinders and is powered both up and down. If you are telling me that your reservoir is not overfilled, but fluid is squirting out the reservoir cap, I'd have to disagree. These systems can be quite different and I'd just have to see it to make any concrete suggestions.
My trailer blew out a "T" yesterday in the lift side. The fitting just let go and started spewing. Ron Hall and I ended up driving about 60 miles round trip and checking three places before we found the fitting. I bought two of them to have a spare. The place were we finally found it is an automotive parts place that specializes in parts for dump trucks.
Jim,
They always say, " It never breaks, when your not using it."
Do you have some pictures of how you have your receiver hitch rigged on the tractor?
Is it a break away hitch in case you get a trailer load of dirt that tries to slide over the fill on the dam into the pond? You wouldn't want it to take you and the tractor with it...
I think the only practical way I could do mine is to get one of those rigs that
ties the 3pt together for 2 reasons.
1. The tongue on the trailer is quite high.
2. It is also quite short, which would put it too close to the rear tractor tires during a turn. It is almost as short as the wife's horse trailer.
What type of brake system do you have on the trailer?
I assume electric. Do you have a manual controller on the tractor so you can apply the trailer brakes as needed going down your hills?
It could be a real catastrophe if the trailer came loose going down a hill without breaks; with the tongue possibly climbing the back of the tractor and taking your head off or doing expensive damage to the back of the tractor.
So then the question becomes... use the safety chains or not?
There is always 2 points of view about safety chains, off road..
Most round balers for example come with a big safety chain. If you use it, you might save the baler from going off over the hill if the hitch bolt comes loose or breaks, but you might have it take you and the tractor on a rollover ride if your baling on the side of a hill. No brakes on round balers, yet, but even with a 2000 pd roll in them they are not as heavy as your trailer load of dirt.
I know you will be cautious.
Ron
