The other day i hit a wet spot on ma big ford 7610, i was nearly stuck, it needed 4wd & diffs, i got out o.k but made me wonder about how best to gain traction. Should i ad wheel weights, front weights???? Wot about psi, i do alot of roadwork but need a reasonable psi so i aint slippin all the time on the green stuff, specially wiv all my hills!!! you can also c ma other ford on the pic!!!! its a beast, i had a tug of war wiv both a john deere 6800 and a case mx110, it pulled em both to shreds!!!!!!!!!!!!!!!!
