Switching side to side

[Reg]

We want them farther out, a LOT farther out.

It happens to be a Kubota and our ASSUMPTION is that the wheels are set to minimum spacing for reasons of shipping.

OK, so we could have the dealer do it, but that would be expensive.
We could get it there, but once the tires are OUT it would be too wide to fit between the fenders of the only trailer we have that is big enough (not a bed over).

The tractor in question does NOT have a back hoe, or we would use that to hold it up.
If we are to maintain tread direction we will have to swap side to side and of course that means having both rear wheels off at the same time.
16.9 x 28 - filled with about 650 lbs of liquid ballast (each).

The biggest problem we foresee if we do this ourselves is lining up the wheel studs.
One possibility for moving them around is an engine crane, another is pallet forks on a second tractor, we have both.

So, we are looking for ideas on how to get the wheels lined up clock/counter-clock wise.
If only our pallet forks had rollers in place of tines<grin>

Those are AG wheels right? Usually they give several options for width - reversing the hub on the rim, and/or bolting the rim with its lugs inside or outside the hub plate. You shouldnt have to exchange sides and so you can do 1 side at a time.

Park it alongside a wall. A guy can shuffle the tires to the wall while the hubs are reversed. Then move the tire/wheel assembly back to the hub. I've done it without a problem. Don't let the wheel get to an angle greater than a few degrees off of perpendicular.

Yes and no.
They are narrower than R4s, but not as skinny as R1s
No matter the tires, the center dishes are "öut" and the rims are mounted with the "tunnels" that the rim/dish bolts go through also "öut"
so to gain a LOT more width we have to get the majority of the rim "öut" while maintaining tread direction we need to swap the outer rims side to side while leaving the inner dishes the way they are.

The manual say we can gain more than15 inches and we WANT that.

Since I posted I have realized that ONE way to align the studs is to rotate the opposite wheel the opposite direction - the differential
will then give us the needed rotation.

In the past I have used my shop crane to move a wheel and tire to the other side.

That is one of the ways or if you are comfortable with your blocking I have seen tractors started and power turned the hubs.
I just swapped mine around a while ago;

I just did this. Swapped liquid loaded tires side to side. 700 pounds of liquid in each tire. Break loose wheel bolts on both sides first. I needed a 6 foot cheater on the wrench. Then jack onto Wood blocking. No 2x4s or concrete blocks... 6x6 or better. You want as wide and stable as possible. Block the tractor till you see daylight between the tire and ground. You'll need clearance to remount the tire. A strap and another FEL to handle the wheels. To rotate the wheel to match the hub, simply rest the wheel on the ground, and push the strap opposite the rotation you want. When you lift, the wheel will rotate a degree or so. It takes a few tries, but works well enough to do single handled. There was too much drag to turn the axles through the diff.

My Kubota M6040 has each rear tire loaded with 775# of rim guard. The rears are 16.9 x 28 - R1's. Thank goodness - the dealer mounted the rears at their widest setting when I purchased the tractor. I know from experience with my first tractor - Ford 1700 - and much smaller CaCl loaded rear tires - - working with my rear tires on my Kubota is not a job I would want to tackle. With the 775# of rim guard, each rear tire easily weighs over 1K#.

With Ag tires you have either six or eight adjustable width settings.

Be MOST careful. A loaded tire, tipping & falling on you, could easily ruin more that just that day.

I have the general tire handling routine OK, I HAD been swapping loaded R4 17.5 x 24 (50 gallons each, about 1/2 ton each) for 18 inch turfs each season and doing them one at a time usually with the hoe on.
That was easy/simple since I could get every thing lined up and lifted with that tractor, swap, then use that tractor to get the next one.

It was just the rotation thing that I had a mental block for.

AGREED ! On edge these can be very dangerous, I have always worked with enough space to hop out of the way if one starts to get away from my control.

PS this happens to be a M7060 'bota

I did 16.9 x 28 R1s. I bought the correct size bolt, but much longer, cut the head off, then ground the shank to a point for a line up pin. I also cut a cross slot on the end so I could us a screw driver to remove.

Install at 12 o'clock. Then work the wheel tire in place. Have the axle flange a little low so the wheel tire leans in as it goes on. Slowly jack the axle up and as wheel tire be comes straight up/down start the bolts. Get a few in and remove the line up bolt.


Be sure to retorque after a few hours use.
