removing the dolly wheels from Air cart and hitching direct to tool bar

I have an old Horwood Bagshaw aircart, tow behind with a front caster wheel arrangement. The caster wheels are a pair of wheels on a walker beem. they are notorious for getting a wobble up over 15km/h
As I drive 20km between Properties, this is a problem.
I am wondering if I coudl remove the trike wheels all together and rest the air cart directly on my tool bar.
There is plenty of wheel on the toolbar to take the weight.
Has anyone done it or seen it??
