Who's better at estimating slope angles?

Some more neat info...surprising information about the "new operator". Check out this link and see what the engineers are designing to predict overturns!

Tractors and Rollover Protection Stability/Instability Feedback Monitoring
Major findings:
􀂄
Uncomfortable slope: 12.92ｰ+/-.58
Would Not Drive slope: 19.06ｰ +/- .66
􀂄
Participants were less able to accurately estimate angles as slopes became steeper.
􀂄
Novice operators were 6.1 times more likely than experienced operators to accurately estimate roll angles, and 96% more likely to properly rank these angles.
􀂄
Younger operators were 49% more likely to accurately estimate the angles than older operators.
􀂄
The stability indicator influenced angle estimations of novice operators

Interesting information.:thumbsup:

Being old and slow that means I'm a hazard on the tractor!

Sounds like I need to sell my tractors and get a rocking chair.

Be sure to get one with stabilizers and a parking brake.

With seat belt and /ROPS maybe.

Even rocking chairs/recliners can roll over...trust me, I know...

I may be just old. But I'm estimating that there study is crazy wrong.

You must have been using them in their unsafe normally delivered condition. Everyone knows you must customize them with ROPS, triangle reflectors, worklights and use grade 8 bolts to fasten them to the 6" concrete pad you poured to ensure level sitting conditions. :laughing:
