 Kubota 4310 stiff riding suspension

hello friends,about 5 months ago i purchased a new 4310 HST, from carver equipment company. it is a four wheel drive with a cab. i am running the R-4 type of tire and i use it primarily to cut my grass. (yes i have alot of grass also, i cut with an 8' rotary mower) while i enjoy all the nice features , such as the A/C, i cannot say i am pleased with the ride in genaral. my lawn is not completely level and there are some bumps but, this tractor of mine does not take them well. it is so bad, i've learned where i need to slow down, so i dont' wind up losing my lunch.prior to owning this kubota i used a ford 1900 with a 6' mower that had turf tires and it was NOT a four wheel drive. i did not have any trouble of this kind before on the same lawn????i have asked around about this problem and i was given a suggestion of putting water in the tires but, i can't see how that would soften the ride.one thing i have noticed is. my problem is compounded somewhat by the HST. everytime i hit a bump, that the shock is NOT absorbed by the tractor very much and is transferrd to me. it is then transferred to my foot. this causes me to not have a consistent presure on the HST pedal. thus, i am causeing the tractor to jerk by not driving a constant speed. i have set the cruise control to avoid this but, that will only cure this part of a greater problem. a stiff ride.am i the only person who is have this kind of experience? i would appreciate any suggestions you may have.thank you,keith wilder

Keith,No, you are not alone. I have a similiar problem with our yard. Haven't had a chance to mow with the 4100 yet but driving the loader around in the yard has given similiar but more mild results than you indicated. We also have a 12hp AC with turf tires, although not Cadilac smooth, it is much better than the 4100. We also purchased our unit with R4s, mainly because I felt they are the best compremise of having the typical R1 Bar type tire, yet provide some charactoristics of a Turf style tire. Not to mention their load rating, and proven ability to outlast almost any other type tractor tire. Unfortunately, I think this is the price one must pay for this type tire. The first thing I am going to try, is decrease the air pressure. 4-wheeler guys do it all the time for added floatation and traction. Only makes sense that it would also provide for a better ride. One must be careful when doing this, if 4wd will be used. The JD manual indicates a need for the front wheels to be at MAX pressure, essentially creating a front "overdrive" effect. But I would think it wouldn't be more than 1-2%, as others have indicated on the CTB. Thinking about that 1-2% ratio. What if one were to decrease the front and rear, proportianally? Wouldn't that keep the front/rear ratio the same? Or am I just not getting enough sleep?

air pressure is your problem, let the rear tires down till the bars on the tires touch all the way across. Probably what you have is the shipping air which is way over inflated for all purposes. The r-4 tires are built with heavier sidewalls as well as tread surface which is the reason for your problem. You should also make sure the tire presure is equal on both rear tires so your deck still mows level depending on your hook up to the mower. your front tires are not as critical due to the osilation of the front axle but they to will give you a smoother ride with proper inflation

You definitely don't want liquid in the tires to improve ride. The air inside the tires compresses significantly and serves as the only suspension system the tractor has--4 air bags. Liquid is incompressible and when placed in the tires to the typical 75% fill level (valve stem up) drastically increases the stiffness. If you need rear ballast use wheel weights. The other posters are right about using the minimum inflation pressure in the tires front and rear to support the weight each tire carries when the tractor is parked on level ground. The required pressure depends on the static weight. You weigh the front axle, then the rear axle and divide each by 2 to get weight per tire. Then go to the Load-Inflation pressure tables provided by the tire companies to look up the required inflation pressures. The Tire and Rim Association publishes these tables also--they are the same for all tire brands that adhere to the Standards. Another major factor for improving ride on a Compact Tractor is to set the wheels out to the widest position permitted by the manufacturer. Having them narrow causes the operator to experience significant side-to-side motion when one wheel passes over a bump or into a depression.

I have a similar problem with my 2710. My R4 tires have the amount of pressure recommended in the manual. The rears have 20 pounds and the fronts more - I forget how much. I'm afraid to let much air out of the rears because those tires are so stiff you can't tell how low the tires are. I have driven one of the rears right off the rim because I couldn't tell it was seriously low. It was nearly impossible to get it aired back up.The field I mow with rotary cutter apparently was a plowed field years and ago and is still pretty rough. I mow in medium range but can't go as fast as I would like or the cutter will cut because of the roughness. It not only beats me to death, I'm afraid I'll shake something loose on the tractor. The loader really doesn't have any play at all any, but it does get to bouncing pretty good.These things just don't have any suspensions under them, and if I did I guess they wouldn't do what they do as well.

Kieth:As a landscaper who maintains about 475 acres of grass with a fleet of Kubota's (mostly L3450's) I know what you are talking about.... We found a very simple solution to the problem years ago..........TOPSOIL. Try keeping a yard or so of good quality topsoil around, when you notice a hole or depression, fill it in!! A little grass seed on top and it will be gone in 3-4 weeks. After a very short time your lawn will be smooth as a golf course, as a matter of fact, that is what the golf courses do. Good luck.
