Trailer brakes working off a Massey Ferguson 100 series is easily over come if it has Pressure control,
All you need do is fit a stronger return spring on the brake arm on the trailer, enough to hold the brakes off when pressure control lever is at the bottom,
This will hold the arms on tractor up at the top all the time, to apply the brakes just move the lever up, the more you move the lever to more it brakes as oil pressure increases, drop lever to bottom to let brakes off, works better than a trailer brake valve,
I did this on a 135 when touring the England countries in 2018, worked a treat
I should have put some pictures on TFF when it went.
They seem good little tractors, but this one had never seen any real work, I don't know about your one, but it looks like it's done more than pull a set of gang mowers occasionally, and drove the village fete parade!!
