As others have said, not too bad to fold/unfold; just take your time the first few times, then sorta becomes automatic.
Tried not to travel with full seed boxes, but when I did, I had a 400 gallon tank full of liquid fertilizer. That helped to balance the unit, but made overall heavy.
Keep tires same brand, size; took 2 years and 3 flats to convince owner to match the 4 tires. Always happened on road with near empty load;  had to call shop to send somone out to rescue me.
Pulled easy with white Case 2290 2WD.
If you're planting beans with it, it takes 2-3 hours with 2 men to change over.  Good method if you only want one machine to plant both crops. Would save a lot of the change-over time if you are using a guidance system and don't have to change makers.
