Replacing front tyres only

The back tyres on our Claas are down to 25/30% and the fronts are buggered. Are the rears too worn to put new fronts on without damaging the transmission because of the difference in rolling radius?

The tractor mostly does yardwork through winter and has the post banger on all summer so doesn't a need a lot of tread.

Id say not, 4wd tractors allways have a small percentage of lead on the front axle so there pulling ever so slightly more anyways & of course thats only when there in 4wd, all the time there not it makes zero difference.
No doubt i'll be totally wrong but lets see what others say.
If your fronts are worn off id be getting new ones on for all the right reasons & run them rears a while yet
Good Luck

Not ideal,but should be ok.Unless through to the canvas or getting punctures why not run the fronts on for another year then replace the whole lot.

Worth digging deeper for more information. Their is an allowance for wear differential per axle, however it is usually quite small. In addition weight per axle also plays a part as does pressure. The obvious advice you will get is to replace them all (especially from tyre supplier).

Replacing fronts without back is no problem if the same profile of tyre is put back on as replacements. It would put less strain on the tractor running with 2 new tyres on front than it would with 2 very worn tyres. Bold tyres can cause front diff problems if run for too long as causes vibration.

I reached the front tyres on our loader tractor a year ago. They were like racing slicks. Goes a lot better in 4wd now, as I think there is less wind up in the diff.

That will be fine , done it 3 times on one claas ares , rears sidewalls went last year on9500hrs
 
As already said,new fronts are better than worn out fronts especially if you hit the brakes on the road and it goes in to 4wd. Could be really technical and drop the pressures a bit on the front
 
You might be surprised if you put new one on. My jd 6420 was at the same point regarding tyrewear, when I switched the 4wd it was certainly noticeable. Got new fronts and no more bang when switching off.
Just changed a whole set and I hadn't realised how much difference it makes. Braking towards a junction,the front suspension would get pulled down two inches,then jump up when the brakes were released

The Health and Safety Executive for Northern Ireland (HSENI) alongside the Farm Safety Partnership (FSP), has named new farm safety champions and commended the outstanding work on farm safety that has been carried out in the farming community in the last 20 years.

Two of these champions are Malcom Downey, retired principal inspector for the Agri/Food team in HSENI and Harry Sinclair, current chair of the Farm Safety Partnership and former president of the Ulster Farmers’ Union (UFU).

Improving farm safety is the key aim of HSENI’s and the FSP’s work and...
