Rotary Cutter Mahindra medium duty 5 foot rotary cutter - replace blades and chain guards

[mswvette]

I am looking to replace the blades om my cutter but it seems the hole to access the nuts is right under the drive shaft in the front.

Any idea what size nut it is?

Do I need to remove all the plastic safety things and the drive shaft or is there another way? Maybe a universal joint on the socket (thought this might not work because of the torque needed to get the nuts off)?

Anyone know of online places that sell chain guards to fit the cutter?

Thanks
