Kuhn 121 plough tyres

[DrDunc]

What size tyres will h4 bodies on a Kuhn 121 multimaster cope with?

I've 520/70s at the moment and it does a lovely job

Do the boards cope with 600/65s?

You will get away with 20.8 tyres in old money.had h 4 boards on last Kuhn plough and 650 will go down furrow but I was never happy with the result.woukd be ok if desperate though.now on lb bodies and 650 tyres are fine

Plus one for above.

We use 600/65R38 with a Kuhn 120 on H4s, works fine.

 

[Bully]

Have run a 6f 122 and still use a 5f 121 and have never really had a complaint about the job it makes with 650s on h4 bodies. We always comment how nice a job it makes. Would not let it put you off definitely.

Thanks all

I'll stop worrying and see in the spring how the ploughing matches up on 600 tyres ?

All 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.

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

If it's not perfect, it's not good enough. I plough on 13.6s at home.

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 expensive

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.

Couldn't agree more, hated the 600's that was on an old tractor of ours, 520/85 's far better on current tractor.
