Dual Wheel size for 3m drill

[kc6475]

Ive never had anything to do with duals, can you change them sensibly on your own if only needed for a day or 2 ?

Smaller duels are easy enough to deal with on your own, guessing 650s are more of a handful and not a one man job, key to making it easier is get your tractor at the right height, I made some blocks the correct height to park the tractor on and the duels just push straight in supporting themselves while I get the clamps on.

Have you any row crops , what size rims has tractor got on at minute 38 or 42 s ,

650 75 38 but no we’ve nothing that size. We have some 20.8 dual wheels from years ago but that’s it.

Don’t suppose anybody knows how low you can drop a 650 75 38 and 600 65 28 machxbib’s?

If they’re of interest I’ve a set of 18.4 x38 stocks duals for sale with the clamps and rings. Rims were shot blasted and painted a couple of years ago. The tyres are quite perished but hold air. £300 +vat. No use for them as the tractor now is on 42’s.

Surely that depends on the load and the speed? Google the chart.

Not as low as you'd think I looked into it last year for my 6155R pulling our 5m carrier and I was told 11 psi but went lower anyway as with that in there was hardly any flex in them

Never dropped mine below 11psi. There is a chart that will tell you when you enter front and rear load rates etc and it will give you a maximum road speed to.

I use a set of stocks step down twin wheels.650 on the tractor 12.4x46
on the dual,makes the tractor about 10 foot wide which is good for
down the road and through narrow gate ways.

Doesnt that mean the dual takes all the weight as it doesnt have the same give ie smaller side wall
Be ok for pulling but hapen. Not for heavydraft

That’s what I run, 620/42 on 76” centres with those. Just a touch wider but leaves no marks
