I plan on making a rear end loader..
We have a front loader on my brother's Deutz D50. i think it weighs about 2000 kg, and has no front wheel drive.
When i lift a wrapped silage bale that is fairly saturated, (it might weigh over 900 kg) the rear end comes off the ground and the 5.50-19 front wheels allmost tear apart under the load.
When i drive through our grassland i get big wheel tracks, and last week, when i drove off the street, into a mud bath it stopped within two feet, and the rear wheels came of the ground, kind of submarine experience when it dived into the mud.
I think when i want to collect wrapped bales in wet conditions, the 16.9-30 duals on the rear of our 5245 will just float on 0.8 bar pressure, without soil or sod damage.
When i want to put a bale in the field where our herd of 15 horses are during winter, it will walk easily through the mud even with a 2wd without duals, because the load is put on the driven axle.
I wont need a powersteering either... That Deutz with FEL is a nightmare for your arms and shoulders, it lacks powersteering..
