  • DIY ROP & Preventing rollover
  • Some few days past, Tim Daley posted about fatal rollover accident and importance following safety rules.

    Tim's post inspired me to begin layout of DIY ROP for Ford 8N tractor, which hopefully I'll begin welding up tomorrow.

    In the meantime, another potential safety device came to mind: An old school liquid mercury contact switch, as used in mechanical thermostats, could be placed in series with 12 volts going to distributor coil.

    Mercury contacts would be adjusted at such an angle, switch would normally pass 12v power to distributor. In case of rolling over, however, tractor's angle would pass "set point" and mercury would slide back away from contacts, cutting power to distributor & shutting engine off (see url photo).

  • It's what's between our ears that saves our rears. We try to make things foolproof, but the fools always stay a step ahead.

  • Brad-
    It's good to want to be proactive and able to perform the work. We have many DIY projects in our HOW-TO's. Here is one for a cost effective 8N ROP device.

  • Tim,

    Thanks for pointing out ROPs design.

    Typically, I will say (tongue in cheek) "Thank goodness we're not getting all the government were paying taxes for."

    In this case, I think it's quite beneficial NIOSH has performed ROPs tests, providing information to DIYer's.

    My design (made from available materials) hasn't gone through any sort of ROPs certification nor testing, therefore, I've fabricated a very sturdy "sun-shade" surpassing strength-of-materials used in commercial ROPs design, such that if my Ford 8N tractor was to roll over, sun-shade-mount would not suffer damage and get bent ;-) lol

  • N's were all designed with a low center of gravity. Rollovers almost always occur because the operator failed to observe the basic safety rules to operate the tractor. 1st rule is to never pull from above the drawbar height. Many have been killed because they failed to pull logs and/or tress from under instead of over that point. Mowing or using an N on a hill incorrectly is the 2nd most accident prone incident. The fact that so many N's have been used and are still on the road without any ROPS is testimony they, as with any machine, are safe when used properly. I'm not sure but it's a safe bet some states require all that OSHA crap be on your tractor now. I have driven my N's on highways in Michigan and only needed to have the (mandatory) taillight on the LH rear fender and a SMV sign on the rear center of the tractor or implement. No need to put flashers and mirrors and whistles and bells all on it. It's your tractor and you can do whatever you want, I'm just saying. You may want to document any DIY project so you can post it in our How-To's.

    Tim, you've inspired me to "read-up" on correct procedures using 8N on hills. Various forums have a lot of experienced discussion of do's versus don'ts. Example: https://www.yesterdaystractors.com/cgi-bin/viewit.cgi?bd=nboard&th=597448

    During search, one result caught my eye: "How fast can a Ford 8N tractor go?" I thought to myself, "Interesting, probably around 15 miles an hour." Their answer was a whopping 96 miles per hour! https://www.farmanddairy.com/uncategorized/1952-ford-8n-sets-land-speed-record-of-96-3185-mph/305627.html Good thing I'm putting an office chair with seatbelt & ROP on my tractor! lol ;-p

    That goes back to Mike Wilson's quote: "What saves our rears is between our ears" where operator's common sense is the most important safety device on the tractor. :-) lol

    If you have too much time and money, your farming head-piece might be a motorcycle crash helmet lol :-) let's just hope there's some common sense inside! .>8Q

  • Tim,

    As always Tim, you've provided excellent safety/operational information.

    Imho, common sense could be relied upon somewhat back in the day...

    Now, not so much ... The People's Republic of California's trying to legislate morality ... Too bad "Common Sense" got left behind by their legislature! ... https://www.youtube.com/watch?v=BYVqmBaqgPU

    Company in United Kingdom wanted to know what they could sell younger generations, so they commissioned a survey ... found 6 out of 10 admitted they did not know how to change a lightbulb ... https://www.thesun.co.uk/news/7211952/millennial-cannot-change-light-bulb/

    Keep these sorts away from vintage machines, who's most important safeguard is operator's common sense!!!

    Sometimes I think common sense is becoming a superpower...
