 Tractor Stability on Hills

KW, I am considering widening the rear wheel span on my 4310. I see from your pics that you changed rims(wheels) at some point. I have the round inside "hub" on my wheel where you now have a "squareish" hub. I look at manual - spoke to dealer - they just speak in generalities about ability to widen tread. Did you need to replace the "circle" design hub to make width adjustments on your wheels?

 Tractor Stability on Hills

The original R4s I had were on one piece rims, the R1s I now have are on two-piece adjustable rims (with the square center hub). One piece rims have two positions and the widest setting is when the valve stems are to the outside. With the adjustable rims the center hub is bolted to the outer rim and can be repositioned to change the offset. The manual has an explanation of this but it's not really clear unless you can examine the real thing. Beware, these tires are heavy, especially if they're fluid filled, and changing them around is nearly impossible do without hoists to move and adjust them. Unlike cars and trucks the axle flanges don't have center hubs to support the rims so lining up the axle flange and rims and getting the bolts placed is a tough job even with a hoist.

Thanks for the info KW. Somehow I got listed as non-premium member and then misspelled my id. My valves stems are already on the outside so looks like I would have to purchase the adjustable rims to get the same width you have.

I didn't experience any stability problems on hills with the 15-19.5 R4s that were originally installed. After the rollover I decided to trade for R1s. The taller R1s raised the center of gravity a couple of inches, and since the new rims could be adjusted wider I had them set as wide as possible. You can't be too stable on those hills!

Buying new wheels may not be necessary. A fairly standard way to widen stances on many tractors is to reverse the wheels. I don't suppose all wheels can be reversed and reversing them doesn't make any difference if the rim is mounted symmetrically on the hub.

Reversing them usually means swapping left and right wheels, which puts the valve stem on the inside. Just turning the wheels around also widens the stance but also reverses the tread. R1's are directional and provide more traction going forward than in reverse. Many areas are served by mobile tire shops that pump out loaded tires, do any work required and re-load them. Such services may be well worth the cost.

I don't have the R4s around anymore to look at, but the manual says the widest stance is with the stems to the outside and that seems correct IIRC. Easy to check - measure the distance from the bolt flange to the edge of the rim on both sides and position the rims so the longest dimension is to the outside, keeping the tire rotational direction correct of course.

Ncrunch, remember that a wider wheel setting is good insurance, but what is a stable condition one day may be unstable the next. High ground water, rain soaked ground, thawing frost, wet grass, and your ability to attain the same position you did prior - all have an effect on your ability to keep the shiny side up. If you have an FEL, carry your load low, and always use the proper counter-balance or ballast.

I believe that my one piece rims on R4 tires are already at their widest (stem out). I can't easily spot the location of bolt flanges on inside of the wheel since the backhoe is on right now but will do it when I drop the backhoe.

I am surprised by the "default" narrow width these tractors have when they leave the dealer. I drove tractors when I was a kid - mowed fields and hauled apples in hilly orchard country. The "old ford" felt very comfortable on the hills compared to the way these tractors feel.

Two people on my street were killed in tractor "roll-overs" when I was a kid. One - a "perfectionist" farmer - was spraying dandelions on a side hill - they shoveled him up after the tractor rolled over on him and caught on fire. My father was there to help in the aftermath. The other was a 20 year old boy who was plowing - hit a rock with plow - and the front of the tractor crawled up in the air and fell over back on him.

I don't care about myself - I have had a few close calls already. But I get nervous when my wife and kids hop on the tractor.

Abbeywoods, you are right about being careful with the FEL. I was carrying a bucket of item #4 down a moderately sloped hill at a reasonable speed. All of a sudden I started slowly rising up in the air - it took me a second or two to realize what was going on. I dropped the bucket and the rear wheel came down.

Now I creep down hills with the FEL about a foot off the ground and wait to feel anything unusual - my hand in position to drop the bucket.

Ncrunch, I had a similar thing happen to me.

I was mowing across a slope (dumb) where I thought I was solid, when all of a sudden I started to slide sideways and the left rear tire started to lift. I didnít know whether to unbuckle and jump (dumb), or ride it out. But in that instant of indecision, I hit the joystick and dropped the FEL, and stabilized the tractor before it went over. Then with the bucked sliding on the ground, I slowly backed down and around, to where I was now pointing up the hill.

Needless to say, I finished the mowing job going up and down instead.
