    I have many customers with irrigation and I run over the lids all the time with my 60" and 66" SuperZ's. They're pretty heavy but I've never had a problem. I've even run over them accidentally with my New Holland (2500 lbs.) doing mulch and had no problems at all.:)

    It is easy to keep driving the valve box into the ground little by little and eventually it will break the pipe....not a big deal to fix...do it youself or you will get hosed with a big bill.

    Ive done the same thing as ed2hess. Drove over a valve box and it got pushed down into the pvc pipe and cracked it. As a matter of fact I posted pics of it in the irrigation section.

    If you want to see the pics and the following suggestions by the irrigation guys and how to fix it check out the post.
    With all the rain we have been getting the ground is soft and it is very easy to push a valve box down into a pipe so I have been very careful to avoid them lately.
     
  7. Ya'll be wise to keep your tires off those valve boxes. How hard is it to center the mower blades over the box? I see more and more of these 36" and 48" mowers doing small yards and the number of broken pipes at valve boxes seems to be going up as well. I can easily see, depending how it was piped in, a repair exceeding 300.00.

    I cringe when I do installs with kids.

    I did one install and all the neighborhood kids hung out there.

    Well needles to say I was there more times replacing cracked pipe under valve boxes, so I cut the boxes in half.

    Then I was there after that replacing pipe under the DCV box.

    I hate kids!...go away
    I guess they played alot of jump on box like smash a badger with a hammer.

    Not all valve box installations are equal... you will encounter varying qualities of boxes and installation methods. Cheap is cheap and quality is quality but there is always the unknown you will run into, i.e. a soft spot created by a leaking line, a stuck sprinkler shooting directly at a valve box creating excess mush by the box, valve boxes located in the lowest area of a landscape that accumulate routine irrigation water.

    In our district one valve box can be run over by a loaded concrete truck without any problems while the one next to it gets crunched so we mark them when construction work is going on. However, all of them can take a direct wheel hit from our large mowers (don't know what type they are but they cut 20' swaths) and never move.
