Fiat 90-90 Turbo climbing some steep hills 

All 4 let go so I hit the brakes. It worked out 5 metres later. Let me know if you have a better suggestion?

@@Amund7 chains on wheels on that conditions you was and chose a small gear before gå ned the hill ,hit the gas in a small gear before the clutch 😒

@@alexharalambie1377 Chains are on the rear wheels, I also put on the front after this video. I am in a low gear, if you watch the tires they are still rotating slowly, the tractor suddenly lost all 4 and that's when I hit the brakes. You should watch the video when the same happens with 8 wheels on the Valmet, that was even more exciting, with hydrostatic drive and automatic 'work brakes' :)
