agreed 520/70 or 580/70 are far better tyresAll depends on soil type and the conditions. Some days 580/70r38s are fine, others they are too wide and whatever you do it's not right.
I really don't like 600/65r38s, the contact patch is too wide for its length. They'll float ok, but they won't bite in and grip.
If it's not perfect, it's not good enough. I plough on 13.6s at home.agreed 520/70 or 580/70 are far better tyres
front furrow will damn near aways be flat ploughing leys with anything more than a 520, that said just crack at as long as your not a perfectionist you will get it good enough to do most of the time
we have a set of 13.6 for ploughing with a oneway plough aswell520 works are not to bad though we actually changed a tractor for 600/65r38 to 520/70r38 with ploughing in mind...and cost 600 are bloody expensiveIf it's not perfect, it's not good enough. I plough on 13.6s at home.
600/65 are horrid. Neither one thing or the other. Really too low for baling work and don’t grip that well. 520/85 or 580/70 are a much better bet I’ve found.
