#10 rotobaler

Hi folks

I've just started the work to revive this rotobaler. It has a few diference than what I see in the book I have and the photos of one's that are around the net. One of these is so e electrical devices I wouldn't have expected to see.

Any ideas what these are? There is a limit switch on the engaging arm that is contacted when the gearbox is set to neutral. The other thing I don't know maybe a resister on the back of the string arm mechanism. It looks like a purpose built set up rather than something someone added themselves from spare parts. Looks like it even has an on off switch.

Thats the overdrive unit to speed up the baler while it's wrapping the twin on the bale,
it may have had the double conveyor when new.Some just had the overdrive unit and no double conveyor.
 
It needs electrical power to make it work and I've wondered just how that would be as when that baler was made most AC tractors were Positive Ground and some were still 6 Volt.
So maybe it matters maybe not.I have many old AC manuals I'll try to find one on that baler.

That would be great. If there is an electric clutch then it will matter if it's 12 or 6v. Maybe there are some parts missing because I don't see any clutches or actuators
 
(quoted from post at 14:02:11 07/29/15) Its not a clutch its an overdrive unit very similar to the ones used on cars like the Triumph TR3 and the Austin Healey 3000

But even they have a solenoid modulator on them. I wonder if that is what's on the lever on the gearbox? I assumed that was a limit switch. Might be a little solenoid I suppose
 
The switch near the lever on the gearbox is to disengage the over drive unit when the baler drive is reversed.I don't know where the solenoid is located on the unit.
 

So that is a switch. Very good. I didn't know it could reverse. The plate clutch only works one direction and slips the other way.

Does anyone think there would be a issue splicing one if the belts on this machine?
 


Hi TF did you manage to find a manual on this overdrive unit? Also on the hook up for the tractor how is that suppose to work? The driveline is cut off on mine but I think the expandable length is already but on the machine. So is that final conections between the tractor and the machine supposed to be fixed length? I haven't freed up the joints on that ladder structure on the end yet but everything else is turning/sliding/pivoting the way it should

Missed one joint that's frozen and the spare is the same. It is a block with a welded together bell crank running through it that operates the trip arm for the twine feed arm. The whole linkage isnin 2 pieces with the upper and lower connected at this crank. Does any of yours have this piece turning freely?
