Keeping the two existing machines isn’t really an option. Ones 30 yrs old the other 25. Basically worn out so we’ve all got to do something and looking around the used market is £100k to get something decent but again well usedWarranty means very little, can Claas put in an 8700 if yours packs up? For that acreage I'd not consider it as an option, between you you already have a better solution
