Safety Issues - Stability

   / Safety Issues - Stability #11  
Welcome!
10-15% slope is not a small slope. If fact many tractor manuals specify no more that 10% as the MAX slope to be using a tractor on period. And, while on the subject of slopes always keep the tractor in a gear, NEVER in neutral while going up or down any hill/slope. Which way to approach a slope is also debated here on TBN almost constantly. And don't go across a slope of any amount of grade to it, because holes, bumps, rocks etc. can and will change the balance characteristics of your tractor, and once you pass the tipping point there is usually no recovery. And it can/will happen faster than you can blink under the right conditions.

So seat belt on, ROPS fully upright, in a gear, and using steadily applied braking, and 4wd too. Hydrostatic transmissions have wet brakes in the actual transmission and unless you're in 4wd if you lose control of your descent speed you will have NO braking action unless you are in a range, ( L, M, H) or a gear for a manual transmission. Keeping you FEL bucket low whenever moving the tractor is essential too, as well as serious counterweight/ballast on the rear end/3PH area.
If towing, only use the drawbar attached to the bellhousing area of the rear end. Anywhere else is above the COG and can result in a backwards rollover/back.

You're getting 10-12" off the ground with one rear wheel is on your way to rolling it over sideways. It's NOT an ATV, and is way more dangerous than what you're used to with them.

You need to change what you're doing and how you do it immediately, or you'll be in deep ***** or dead sooner than later. Rollover deaths are the leading cause of fatalities on tractors across the board, regardless of tractor size.

So get ballast, and fill your rear tires first before doing any more work. It surprises me that your selling dealer didn't recommend filling the tires to begin with; I know mine did, and I probably knew less about tractors than you did when you got yours.
As far as getting different rims or adding wheel weights Kioti's don't go that route much from what I've seen.
Mostly they either have AG or industrial tires and the wheel spread is about what it is from the factory.
Rear weight, like a BB or backhoe is pretty common, but some build ballast boxes and fill with rocks, concrete, etc.

Take it slow for many hours after you get the tires filled and rear ballast at the 3PH, and use the lowest range or gear possible when doing any slope/grade work. Common sense is helpful too, so think about what you're trying to do and access if it's safe. Carry a cell phone or 2 way radio with you and let people know where you're going to be if any kind of risk might present itself when working alone.

There is a LOT to learn so take it easy and get to know your tractor, and come back here and read everything when you're not on the tractor, and ask lots of questions- that's how I learned most all of what I know about tractors; right here, hour after hour from those more experienced than me. And there are a TON of people with way more than I know about tractors on here everyday.:thumbsup:

Interesting thread. It got me wondering, what is the maximum slope I can safely drive across before tipping over? With my flail mower and the bucket low it seems pretty stable on a 15-degree slope.

Is that 15 Metric degrees?

1) The only sure way to establish a limit is to exceed it. Make sure to wear your seatbelt.....

2) My Kioti dealer loaded all four tires when they prepped mine, based on my home's terrain. Didn't even ask, just did it. Good man!

3) 4wd (front assist, whatever they call it) is your friend on downhills. The brakes are on the rears, the weight is on the fronts, and sliding downhill is not fun.

4) If in doubt, stop for a moment and see if you can figure out a better way to approach the situation. I was on a steep slope on my property and got too close to a hole I was filling - the edge gave way and dropped my right front wheel in until the axle was in the dirt. I thought it was going over, but it quit sinking. I bailed off and looked the situation over, realized I was not going to get it out the way it went in, and ended up driving it down into the hole and out the downhill side. Lucky, and a learning experience.

5) Wear your seatbelt.

6) If in doubt, DON'T.

Such a subjective question/answer. So many factors come into play. I have held a side slope (angle finder verified) of 30°, but let me tell you, it's pucker city. I have made my tractor more slope stable, and could not do that in Stock form.

No one can give you an answer, that you can rely on. Speed, terrain, tractor COG, operator skill and 'feel' are major factors.

I have tested my set up in semi-safe conditions, like a ditch, with the tractor on one side, so if it did roll, it isn't going far, not a 'to the bottom of the holler barrel roll' situation like I find myself in alot of times. Getting comfortable in that situation can help you learn your and your equipments limits.

I guess I'll just have to get a feel for it. I wasn't sure if anyone had any info on theoretical maximums for a given tractor.

I'm pretty sure the manual will state not to exceed 15-degrees on a side slope. That doesn't mean that it won't hold, but the manufacturer isn't making any promises regarding stability after 15 degrees. Even the smallest lawn tractor has the 15 degree notice.

I agree with what you say.....except for the "feel" part. I hear that very often on TBN when it comes to running equipment on side hills. Many people talk about the "feel factor" or the "pucker factor". - "Take it slow and see how it feels." Sorry (I'm not picking on you), but that's is my pet peeve, "Science (physics) don't give crap about your feelings".

Many people's "feelings" will have them quit way before the tractor is in danger of rolling over. Most people wouldn't attempt your 30 degree test, even with a capable tractor. And because a lot of tractors do roll over we also know that those drivers feelings were also misplaced.

Like Teach said: "1) The only sure way to establish a limit is to exceed it. Make sure to wear your seatbelt..... "

As new tractor owners (and we all were at the beginning) nobody here knew what they didn't know. Ignorance is NOT bliss, in fact it can kill you. Lots of good advice in this thread, but there are several threads here on TBN that talk about tractor stability and rolling. I suggest you take some time to search them out and read them so that you understand just what the hazards are and how to mitigate them.

For example, no one here has mentioned that the higher the bucket is, the sooner the tractor will tip on a side hill. Or that dropping the bucket can stop a roll if there's enough weight in it. Dropping the bucket can also stop a downhill runaway, so keeping one hand on the bucket lever is a good habit to get into. Work carefully and slowly to give yourself time to sense the tractor going off balance and a wheel lifting. And you might consider installing a tilt meter so you have a sense of how close you're coming to the limits of stability. IMHO, dropping a wheel into a hole on the low side or running over a rock or root on the high side are the quickest ways to get yourself in trouble on a side hill, and I can't emphasize enough that going slowly gives you the best chance to catch something bad before you get into trouble. The ground is steep here, and I spend a lot of time going straight up and down the grade, or slightly angling and making big up/down traverses to move over just a few feet. Yeah, it takes longer that way, but it takes a lot more time to pick up a turned over tractor or recover from an injury.

All good advice, though I'd put "widen stance" first (as some did).
Beyond stabilizing, one safety action I've seen violated time and again is folding down the ROPS and leaving folded. Many folks park their tractor in a garage with a standard overhead door. There are few tractors that will go through a standard OH door with the ROPS up, so they get folded down. Laziness sets in and the ROPS ends up staying down all the time.
Don't do this; make it a habit to have the ROPS up and locked (pinned) and your seat belt fastened. Too many older tractors killed their owners because they lacked safety features; it is especially sad to see owners of more modern tractors die because they failed to use (or defeated!) the safety features innate to their tractor.
