Kubota M9960 Rides Rough Please Help

[brushcutter]

Have had little to no wheel slip with the drill. Case dealer is about an hour away so trying to stay in the local area. Both the Kubota and JD are 15 min drive tops. The New Holland dealer hear has terrible service other wise I would look at a New Holland. That and we had a New Holland C238 CTL which is why we know about the service problem but also the ctl was lacking in power. The service was a bigger factor in going to the cat then power but the cat we got could run circles around the New Holland machine.

Well I guess this begs the question whether all tractors this size ride "rough" or is it just Kubota? Do the JD guys complain of the ride also?
Nobody is bashing brands here, just trying to figure out what works best.
Until the cabs have suspensions, which many larger tractors do, I can only wonder what could be the difference from brand to brand vs psi or tire construction
I was totally disappointed with my stock Kubota seat and the dealer would not install a Michigan seat in it because of the warranty. Well it's out of warranty now so I might try that first, plus lower the rear tire pressure a little.

You got a big difference in operating weight when looking at Kubota compared to other brands in the same HP. Usually a good size scale in the 40 and more so the 60 series. You don't notice much like the fella stated when just putting out hay and messing around but hook some large equipment up to it and it and time to hang on... you also have to take in the dimensions of the tractor and how weight is distributed.. Even JDs E series tractors at 85hp outweigh the 9960 by over 1000lbs I believe

Theres also no reason to go up to a 135 when the heaviest equipment your pulling is a 15ft wing.. Just find a tractor with weight to the ground. Id take the JD over the Kubota any day. But Case, JD, Mahindra, NH, Massey offer 100hp tractors that all weigh around 9k tractor alone and would handle that type equipment fairly easy

but you will never loose having more HP than you need

 

[brushcutter]

That was our thinking can't hurt having more hp. At the moment our planter is the biggest strain on the tractor but it is rated at 80hp min to pull it so not hurting for more hp. We are looking at getting into hay baling for people since we already do weed spraying, fertilizer, planting and other things for people. A JD 5M would possibly do what we need but where thinking at this point we should just go to the larger class tractor for any future growth. Wish we could keep the 9960 it would be a good rake tractor if it wasn't so rough.

If you trade better get a couple days of demo on whatever you choose. You are going to take a bath on the trade. Certainly would suck to end up with another "rough riding" tractor.

I'm sure one of these would do the trick.
Stidd is unaffordable to me but if I hit the lottery...
happened to see this looking for a boat seat.

I have an M108X and the tire manufacturer even replaced all my tires with radial tires, a cost of 10,000.00 they told me, at first it seemed better but within a few weeks the tractor was bouncing around on perfectly smooth pavement, I gave up and never mentioned it to them again, they tried and wasted money without fixing the problem, I think the wheels are just not round, I have checked them with a laser and found ever one to be out of round, but they tell me it's a tractor, what do you expect. I actually think the wheel rims are too weak and bend when we hit deep holes in the fields. I just think the wheels are not strong enough for this size of tractor and self destruct. That's just my opinion, but I would love to get a set of wheels to try out.

God bless

Bummer. I'm surprised you got the tire manufacturer to replace the tires. My M9540 rides fine with Radials. It does have a gentle side to side sway when running wide open in 12th gear on the highway. I assume that's caused by wheels. I've never investigated that or followed it down the road to see. Pretty common in AG tractors it seems.
