Simple answer, buy a second unit.....
For years I farmed with one unit and used it for everything but I finally convinced my partner (wife) that a second unit would make life easier... and it did. With 2, I don't have to constantly change implements out (and some of mine are heavy and have multiple hydraulic and electronic hookups) and I can leave one unit free for around the farm chores if necessary plus I don't accrue so many hours per unit with 2.
What I did was buy an identical unit to the one I already have so services and filters and grease points are identical and they both are on the same service schedule too. Makes life much simpler for me and I can go from one to the other and know exactly how both will perform because they are identical.
It's only money and you cannot take it with you so spend it...
