Umbilical help

Looking for some help/advice. Looking to start doing our own umbilical spreading and was wondering about a couple of things. Thinking of going 5inch pipe and dragging 4 inch in field. 8 or 12 m dribble bar? Does it make much of a difference to system speed/output etc. Also have an older 6 cylinder 110hp tractor available for dribble bar. Would this be suitable for the job?

Have you considered an underground main? We have 950 metres of 6" pvc 12 bar pressure pipe and 3 hydrants. It also goes u der 2 roads. The pipe itself was about £10/m which was the same as the 4" lay flat we bought ( about 8 years ago). We have a Doda L35 pump and get outputs of 80-100 M3/hr depending on elevation with total pump distance of 1400-1600 metres.
We have a 6.4m trailing shoe pulled with a JD 6430 no problem except steep bits when it's wet.
 
Those pipe sizes sound about right. The width of dribble bar wont make any real difference in speed of doing the job unless you have a very high output pump, but just mean you'll do less passes, it would probably more come down to budget. I would have thought that size of tractor would be fine as long as it has a decent hydraulic pump to run the macerator

Should add on fairly flat land and 20 odd acre fields.
Why not go bigger? I am on 15m dribble bar and wouldn’t want any smaller. Cuts down the wheelings and less overlapping. Done plenty of small fields and it’s never felt too big.

I have same setup re hose - all 5” supply and then 500m of 4” to drag

Is that twin mascerator?

if you are putting it all on grass I would look at a trailing shoe

Would an older tractor have the hydraulic capacity to run twin mascerator is my only concern
I don’t see why not, my wee 415 has the oil flow turned down to 40% to each macerator. Speak to James at Agquip he is incredibly helpful and can tell you if it would be a problem but from what I see it doesn’t take a huge lot of oil flow

The type of terrain he’s spreading on and distance he’s pumping would be a consideration for width.
I’ve the 12 meter version of your dribble bar and it’s great but you need to be getting 30,000 G/H or it will feed the top side of the dribble bar far less than the bottom side on a slope.
It’s obviously fine on the flat at 25,000 gallon but need plenty flow for even spread in undulating type terrain

Good to know, our ground is all flat for the long pumping, and the slopey ground is usually only out about 800 metres so never had much problem with flow or putting it out to the one side. Damn good machine all the same, macerators are a lot simpler too than your normal Vogelsang ones

have you every flow tested it ?,

Have definitely thought about underground pipe but am thinking buy lay flat to get started and add underground later to get more distance.

Cost. Thought 12 would be a good middle of the road size.
