3 point Hydraulic problem

[peterryg]

Iv a Sunshine ZL1-225 grey import, that l need help with regarding the 3 point linkage hydraulics. Initially the hydraulics would every now and again lower by itself, and occasionally wouldn't respond to up/down commands.
Now it dose not respond at all. Its currently in the up position. Even when l turn the Valve below the seat, it still sits in the up position. Really not sure what it could be. Any advice would be greatly appreciated

I'll take a punt here. Model number ZL1-2254, do you by chance mean ZL1-225?
If you do, does it have a monroematic control system on it?

 

[peterryg]

Yes that's right Typo. my typo. ZL1 225 Yes it dose have the monroematic control system on it.

First place I would look would be controls/switches and sensors, monroematic can automatically lift in reverse, when turning etc. Perhaps a control is set incorrectly, loose wiring, bad connections, lever in wrong position, feedback rod adjustment incorrect.

Most 3 points are single acting so if you don't have weight on it you can't get it to go down.

Thanks for that. Will have a good look around. Hopefully its something obvious like that.

Thanks for that. Definitely has weight on it.
