How do you prevent backward upsets?

In a backwards tip, the tractor can hit the ground in less than one and a half seconds.

Factors that cause a tractor to tip over backward depend upon the load and the height of the hitch from the ground.

  • Hitch only at the manufacturer's recommended height.
  • Engage the clutch pedal slowly and smoothly. Be ready to disengage power quickly if the front end begins to come up.
  • Start forward motion slowly and change speed gradually.
  • Use counterweights to increase tractor stability. Follow manufacturer's instructions.

  • Avoid backing downhill.
  • Drive around ditches, not across them.
  • Back your tractor out when stuck or tow the stuck machine out with another tractor.
  • Turn downhill when working across a slope.
  • Drive straight down even the gentlest slope. Do not drive diagonally across it.
  • Do not hitch a load higher than the tractor draw-bar.
  • Do not coast downhill. Before starting down, shift to a lower gear that prevents freewheeling and excessive braking. Try to use the same gear to go down a hill that you would use to pull the load uphill.

    How do you prevent sideways upsets?

    • Set wheels as wide as practical for maximum stability.
    • Avoid depressions and obstacles.

    • Turn downhill, not uphill, if stability becomes uncertain on slopes or ramps.
    • Keep loads, implements, or loader buckets close to ground.
    • Keep side-mounted implements on the uphill side.
    • Match speed to conditions and loads.
    • Back up steep slopes or ramps.

    • Lock brake pedals together before high speed travel.
    • Slow down before turning.
    • Use engine for braking when going downhill.
    • Stay away from the edge of ditches and streams.
    • Do not try to cross steep slopes.
