@LowBoomLowDrift Transport tires on the drill should be a radial tire to dissipate heat aswell as 2x the wieght rating required to compensate for the additional load of towing a full cart and rough roads. 710/50R26 on singles, no walking beam, would be the tire i would tire to fit into the design
@LowBoomLowDrift I have no idea but bourgault 1300 bu cart full tends to effect germination in cart tracks. I can't imagine 1500 would be better. A bogie axle setup would be nice but complex.
Maybe dual 1400 lsw tires would be ok. Its a battle between what can be practical and what is needed
@LowBoomLowDrift On the drill part 15-19.5 r4 tire would be nice because its a construction tire and likely tolerates stalks, and they are big enough to keep rolling in mud. Air cart need more axles and tires to float that much. naf makes bogie systems for claas etc to spread out the load.
