Put things together over the weekend. I made a clevis to attach ram to slot hitch. Then to see what depth I'd get with the plough down, I put the tractor on 6" blocks and attached the plough. This showed I'd get about 7" of depth. More than enough.
To test the lift, I used the simple method of using two of the wires from actuator and touching them on the battery terminals. Pleased to say it lifted the plough with ease and gave enough ground clearance. Though a problem has shown up.
The actuator works on a screw system. Motor turns and the ram screws out. When the plough is raised, its weight causes the ram to slowly turn the motor and the plough slowly lowers.
So I am now looking at a method of locking the plough in the raised position. This I think can be done using the lift lever with a cable attached to the hitch. It could also be a method of controlling plough depth.
I may get time tomorrow afternoon to see what I can do and my next update will contain photo's.
