Absolutely shocking to grip I had to go and rescue a deutz on a tarred road one day it spun out going uphill with new bkts on it.
I think it had good years from new and never a problem

And look at the picture I put in the workshop thread them tyres were put on 2500 hours ago l
What pressure was in the tyres . Every loo la on YouTube with a tractor stuck has hard tyres . I made up a gadget for rapid inflation of tyres and have air on the tractors .
I do Tillage and sprained at 13 psi for haulage generally up around 28 depending what I am doing.

I don't know what pressure he had in them but the old ones used be pumped fairly hard anyway.

Mine shows 30 at 40%
And 0 at 8%
For reference at 30% on my dial it shows 18 on the screen.

Anyone fancy a project? Think the price is a bit high considering the problems!

Considering the amount of bits it needs throwing at it 12k is probably closer to the mark.
Pughs have one for similar money but not listing faults it likely has

And this has been on the market at least 12 months
