Yeah 4220.4220?
3 day demo of a 4220 in 2017 with a 3m trio on Holderness clay and I was astounded at how it gripped and pulled.
Lifted the trio like it wasn’t there too.
Michelin vf tyres not had it on a weigh bridge to set them exactly but at 19 psi it scrabbles around too much for my liking. The jcb man said I'd be able to run at 14 but they're slipping the rims inside tyres at that
It does it ok but 7820 JD will pull it 4k faster lifts it no bother
Anyway this is off topic lets get back on track
