- New Holland TN75SA
hi there everybody, i have a problem that New Holland uk can not help with and Stocks uk wheel manufacture, are unable to help with.
I have a TN75SA that came with the balloon grass tyres, 12LL x 16 front and 22.5LL x 16.1 rears.
With these tyres and wheels the tractor is to low for towing a proper tipping trailer, so i had the idea of swapping the wheels and tyres for a more traditional set-up, i then looked around for a set of wheels.
I found a pair of 30" rear wheels with 16.9x30 tyres, this is where the problem starts !!
I can not find my drive ratio for the gearbox, so i don't know if the front wheels should be 20 or 22.5 or 24 or 28.
i have seen photographs of TN75 tractors with all four sizes on.
Does anybody know where i will find my drive ratio so that i can get the right setup, so as not to destroy the 4x4
