Setting trade ties maximum width

budepps3760 · Dec 21, 2019

Several months ago I rolled my tractor over and by the grace of God survived. Ended up having to buy a kubota mx5100 as a result. I would like to set rear tires to maximum width to hopefully prevent it from happening again. Tractor has loader which should help and will load rear tires once set to maximum width. Would appreciate your instructions on how to accomplish this.

I don't know about the M series. My L series Kubota has two piece rear rims. I think three bolts hold the center to the rim itself. There are three different widths available as options. Look at your rear rims.

Consider adding wheel spacers to further widen the stance. BroTek's go on easy, and are well made.

You should be able to find the instructions in your owner's manual. it will show you the acceptable settings. Are the tires on your new tractor loaded? I've been resisting doing mine for 20 years but I may become a convert.

I would call them and double check. My LS wasn't officially supported, but I called them and they were able to make it work.

Depending on the wheels you have... Looks like the wheel is a two piece system. Remove the wheel from tractor. Dismount the center dish and remount to place the tire at your desired spacing. You might have to reverse the dish and swap tires side to side to maintain the correct tread direction. Wheels from the factory are usually set narrow to ease transportation.

Moved my rear tire center line from 60 inches to 68 inches. That 8 inch doesn't seem much difference but...I can vouch that the few inches difference makes a tremendous improvement in stability.

Watching a video of man widening his rears on a kubota. In this screen shot he has both tires off and back is up on a single bottle jack with nothing under either axle to support in case something bad happens. And then his toddler comes walking into view and walks up to the suspended rear. No sense of urgency in the father trying to get the toddler away from the tractor. WTF is wrong with folks now days!? Don't you know accidents can happen any time?

Hello budepps3760, an alternative is to use dual rear wheels. MASSIVE increase in stability. The main draw back is the price of a 2nd set of rear tyres. Be choosy about which dual system you use as some are better than others. Idealy you want a quick release type, especially if you are going to mow hay or plough, and need to drop the outside right tyre.
I recommend you use a tyre with a 45 degree tread bar angle as these stick to hillsides best.
Duals will widen you to approx 9"6' to 10"6'depending on outside tyre size.
How wide are your gates?
I also advise a 4' gap between duals to allow mud to drop out. Narrower and the mud is retained.

My MX5800 is about 2 years old - I had the dealership dish the wheels out to the widest width. The rims are 2 piece. I have 3 sets of Kubota wheel weights. I'm glad I had the dealership do it - after watching it be done.

The Op Manual for my M6040 says - "no wheel spacers, no double tires". My tires have split rims. Outer rim - inner center. The rear tires have eight varying widths - the front tires have six varying widths. My rear tires are loaded with RimGuard and weigh well over 1000# each. I'm not set up to handle a tire at this weight. I would have Les Schwab come out with their service truck if I wanted to alter the rear wheel width.

Safety first. I have a very good idea how long it would take the coyotes to find me - trapped under a fallen tire.

I know that story myself. Had to remove the tires / rims and center section on one of my M9's this summer. So long as one keeps the assembly vertical, no issue. A bit out of vertical, big issue and mine aren't loaded but the entire assembly with cast centers weighs in about 800 pounds a side. Much easier to accomplish with a truck mounted crane (cherry picker). A falling tire / rim assembly can squish you in a second.

I have this picture in my mind. One of my loaded tires falls over on me. Take a brand new tube of toothpaste. Take the cap off and set it down on the floor. Step down on it as hard as possible. You get the picture.........

As with most things if you watch an experienced person do it, it looks easy but it is not for the novice. If the tractor has the multi-piece rims you can make them wide, add the liquid weight and if needed add cast iron weights. If you need more then that you should not be driving there. Thank the Lord you are safe. At some time maybe you could share your story of what happened to cause your accident.

Have not yet loaded but will as soon as I maximize tire width.

I was looking at the pictures that are on the roll over thread and it looks like the wheels are wide but they are not at the widest setting. The center disk are turned the correct way for width but the rims look like they are on the inside of the center disk. They can be set to the out side of the disk and gain a couple more inches in width. As stated before load the tires and buy some iron weights for the rear.

I know some one in the other thread suggested running with the bucket down low to fined the stumps etc in the new, to you, ground. If it has been logged as it looks like in your roll over pictures I think I would chain a large log, 6 inches in diameter, to the front of the bucket parallel to the cutting edge and just slightly wider then the tractor. It needs to hang down and be able to swing a little. You can watch how it is hanging and stop before striking the bucket against a stump or big log that is hidden. Those hidden objects can jar your teeth, if you know what I mean. Remember to keep the bucket and log low to the ground.

Best of luck with your adventures as you get the place cleaned up. Thank goodness you were not hurt worse then you were. And thank you for sharing your story. It is important to remind ourselves how easily *hit happens.
