Hi
new to here and not really a farmer (car and van mechanic with a mot station and a small holding)
I bought a jd6230 standard 2009 with a loader a few months ago for doing our hayledge,no experience with tractors and only used to driving my international 685xl.
when clearing the fields and stacking found that when you release the brakes the front end seems to bang and shake?
if anyone could advise me i would be really gratefull.
Am handy with the tools but would this be a dealer job?
thanks in advance

It's when the 4wd comes out of gear after braking. Obviously it's winding up for some reason so check your tyre sizes and see if wear is similar front/back. Some will say to change the axle oil, maybe it will help, maybe not. I gather the slip additive may reduce it.

best bet might be to put a switch in it somewhere to prevent the 4wd coming on when you brake.

My second thought as above is the tyre ratios are incorrect front to rear, or the fronts are very worn from loader work.

thanks, I did change axle oils and serviced it when i bought it as a precaution,it is a ex council one with massive grass tyres so maybe thats the cause?
Is it ok to leave then do you think?
Thanks again

Can you tell us what size tyres are fitted front and rear and estimate the wear % on each.

You can't tell him what they should be without knowing what front axle or diff is fitted. His instruction manual will tell him how to find out and work it out, but JD like to make it complicated :banghead:

It's a lot worse if you are turning when you release the brakes, it's second nature now but around the yard on hard standing if possible I straighten the wheels up before releasing the brakes, then it doesn't bang when disengaging 4wd.
You can check if the wheel ratios are wrong by driving straight for a distance and seeing if it still winds up and bangs out of 4wd

It's perfectly normal but will be exaggerated with the turf tyres. They have more surface area in contact with the road so the tyres can't slip as easily.
when the 4wd is engaged with the brakes, the front wheels will be geared to turn slightly faster than rears (otherwise known as lead).

Don't be tempted to to put a switch in to disable it. Health and safety would have a field day if you have an accident an find you've modified braking system

Until you have an accident on the road and then, you could be in big trouble.
yeah, there's that, risk would be minimised if it's one driver/owner. Makes me laugh really because if the 4wd bulb blows you don't get 4wd which is mega dangerous in a damp sloped field With a trailed forager and loaded trailer turning on the headland. Been there. I presume this would mean you also wouldn't get 4w braking on the road...... a blown light on the side console is easy to miss.

The 31 March deadline for responses to RABI’s Big Farming Survey is fast approaching and everyone linked to farming across England and Wales is being encouraged to take part.

“The support that we’ve received since the launch of The Big Farming Survey in January has been incredible. We’d like to thank everyone who has already completed the questionnaire or promoted the research project more widely,” says RABI’s Chief Executive, Alicia Chivers.

“However, the more comprehensive the data collected, the better the reflection on the daily realities of people from all sectors of agriculture and across all regions,” she adds. “We therefore want to hear from farmers, farm workers, contractors, spouses, adult-aged children and...
