Mounting a Tractor Hedge Flail
awemawson:
So having got them off, I mounted the jaws on the brackets, which I'd bolted to the axle yesterday
awemawson:
This allowed me to start measuring up how it would interface to those two spars I was about to make. I had made up a timber 'mock up' of the spars accurately set to replicate their spacing and width, as having the differential 'lump' and the pto gubbins in the way otherwise made measurements impossible.
First offering up implied that the 'jaws' nicely fell on the centre line of the spars - but this was wishful thinking as the jaws obviously weren't set on the stands quite parallel :( Never mind they fall within the width of the spar - I intend to cut deep slots in the spars -insert the jaws and weld them together.
awemawson:
This shows the off set of the jaw centre line in a spar end
awemawson:
So I placed an order for the new 100 x 100 x 6 mm box section and the very heavy angle and plate need to replicate those spars. All came from Austen Knapman who carry a very wide range of steel sizes - and deliver for a not too exhorbitant fee:

So the next thing to do is work out how to jack up the flail to remove the original spars - needs serious support as it's a bit heavy and I'll be under it :bugeye:
But I also need to drain the 25 gallons of hydraulic oil from it's tank and fit either a 'Quick Disconnect' or maybe just a gate valve. At the moment the hydraulic pump that turns the flail head is just hanging on umbilical pipes making fitting difficult onto the pto drive. If it is separable it will be much easier

It's a beast for mount torque. Hope this works!
It wants wheels back there somehow, though I can't think of any particularly convenient or even useful way. that would work.
The articulated mowers I've seen the town run have a side frame mount, mid tractor.
