I don't know what those weigh, but 17.5L24s are about 950/1,000 lbs each with RimGuard.
I don't always have the hoe on when I change my turfs to R4s, but the out riggers on my hoe only give a very coarse height adjustment.
They're not the same diameter, so there is always need for a slight height adjustment.
One trick you MIGHT try using with (relatively) light wheels is to "ride the shovel".
Steel shovel, get the wheel close and put the blade in under the tread edge, sit on the handle.
The leverage is good and if your balance is fair you have both hands free for jiggling and juggling things into final position.
