How do highway departments do this?

[Baby Grand]

At some point it seems that the equipment becomes less important than the experience and good judgement of the operator. It just blows my mind, driving past fresh mown right of way slopes that look impossible. Very humbling.

The slopes im talking about are far more than 30 degrees and it defys logic how they can do this, up and down ok i can understand but going sideways is amazing. These are just standard looking kubota and deeres wirth 8' mowers. Theres no way i would even attempt that so i huess i would be fired ).

Im not saying I dont believe you, but without pictures, its hard to believe that a standard tractor is mowing sideways at "way more than" a 30 degree slope.

Measure one.

a 6/12 roof pitch is hard to walk on even with shingles. And is pretty steep. Yet it is still under 30 degrees.

Get a cheap angle finder gauge from harbor freight for $2, and measure the slope and take a picture:thumbsup:

Hard to understand how they do it, MDOT began experimenting with remote controlled mowers this year in some areas.

Bigger tractors are wider so they are more stable, but they are also taller.

Heres a video I like of ROW mowing in Europe using some big Fendts with dual wheels.

Now this is what I'm talking about...the DOT mowers I saw were on a steeper hill than this going sideways...I would say 20 deg steeper...I'm not kidding....

They have their rear wheels set all the way out. Ill bet youre seeing 30 degrees and judging more. Way more than 30 cross slope is out of the question. Up and down could do more ... probably a hard limit of 40.

Thinking the same.. 60 degrees is quite a bit ..
