Wondered if any body has had problems with cracked rear wheels on 18.4/38 .running with duals for drilling 2nd set now starting to go around the bolt holes and these were surposed ot be a stronger set .tractor any done 3000 hours they are susidising new set but still going to cost over£1000 . welcome any coments
had similar problem with ford/NH, best solution is rims with the continuous flange welded all round. A good fabricating firm should be able to cut & fit a pair for you, or try one of the east anglian wheel supplier firms. presume you do run the duals a couple of psi’s lower than the tractors to reduce overloading the tractor rims?
We cracked both rear wheels on our 6910 last autumn after about 180 hours work running dual 650s. dual wheels at 4 psi below tractor wheels had to by new centres and a strengthing kit total cost about £1600 has solved that problem but wht about the bank manager
I hope you’ll be able to run all 4 at the correct pressure now, and save by less soil damage.
Sounds like we need to be more careful specifying wheel equipment for tractors we buy. I buy 2nd had, but the last two have both come with no back wheels (previous buyers wanted to keep those silly 65 series). The 64 wheels came off the previous owner’s new tractor. I had specified the tyres, but never gave the wheels a thought.
My 68 wheels are welded centre 18.4R42 which we use with duals, and have never had a problem. Previously these same wheels were on a 2wd 4040 – with 5.5 tonne on the back axle before hitching anything. Still no problem.
We bought a ex demo 6810 with 18.4 38, and within 6 months they had cracked around the bolt holes. We sent it back to the dealers who then replaced them with a set of solid rims! I think these are the rims the tractor should of come with to start with, but im not 100% sure!
John Deere seem to sending tractors with all sorts of wheels from what I have seen certainly all 50 Kph machines have solid wheels a lot of 68,69’s have solid wheels or seriously strengthened rims and centres with a reinforcing sort of ring on the centre and longer studs . I haven’t seen many 64’s – 66’s with solid wheels and only a few witth reinforced rims but none seem to have the reinforced centres. Our 6610 came with very standard wheels 18.4R38 and there was no mention of stronger wheels available even when we said about people shearing studs and rims cracking we were just told it was sorted.
It is very interesting that there has been a fair bit said about 6000 John Deeres and 60 / TM fords but nothing has been said about Case Mx’s which are absolute Sods for cracking rims etc Some one I know was going through a set of rims every 4-6 weeks one Autumn before eventually getting some purpose built solid rims made. There original rims looked very similar to the offending John Deere Rims and were probably made by the same manufacturer ??
Just goes to show what your paying the extra money for when you buy a Fendt.The wheels on our Fendts are at least 20mm thick not thin pressed out tin. We ran a 200hp JD on duals and had no trouble with those, sounds like there making them a lot thinner now to get the cost down.
