Hey there.
I just built a set of wheelie bars for my WD45 pulling tractor.
Before I put the finishing touches on them:

I have seen numerous photos of them, and they all have the small skid plates that sit horizontal to the ground, while the tractor is on all 4 tires.

Wouldn't it make more sense to have those skid plates horizontal to the ground when the tractor has it's front end in the air, so that more of the skid plates are in contact with the ground???

Any comments?


thanks.

yes, i have been to a few pulls and the skids i have seen would be parallel when the tractor front is in the air not during normal driving.  otherwise they would dig into the ground
 
just remember that different pulls use different rules.  Not all use napta rules etc... just make sure they are correct and safe for where you pull
 
good luck
 
Napta rule
 
4. Wheelie bars are required in Divisions II, III, IV & V and should not be attached to the draw bar in any way. Minimum requirements for the wheelie bars are as follows. 10" maximum above ground. The back of the wheelie bar is to extend 5" behind the tire radius. C: Pads = 5" square minimum, spaced minimum of 20" from outside each pad. D: Stabilizer bar system must be able to support the weight of the tractor in the heaviest class pulled. E: Jacking up the pads so the tractor is completely off the ground is a good test of the strength of the system’s support ability and the NATPA Tech Crew reserves the right to perform this test at its discretion.

Just make sure that they will skid and not dig in

hey CAL(KS), these were the exact rules I built them buy, but they just didn't say what angle to make the plates.

Pivoting works!

Thanks!

Hate to burst your bubble - but looking at your picture - and understanding that they pivot - I believe if the front of your tractor raised up to the point that the wheelies contacted the ground, the front / leading edge would dig in and cause the foot to flip around and end up on top of the square tubing.
Again just my opinion from looking at your picture.

If you angled or beveled the front of the pad that would work, right?  Out riggers on trucks are made that way so they will slide and not dig.

I agree with gary,  i made a set that pivoted and they did roll over and made 2 nice furrows in the track at the most inoppurtune time.   matching the angle to the expected front end height is the way to go. remember the kiss method.   (keep it simple stupid)

its hard to see, but i've got the tubing cut so that there isn't much travel in the pivoting.
It sits level now, and bends back (which would be level if the tractor was in the air, but won't go any further.
The steel is 3/16, and as long as the grade 8 bolt doesn't sheer, I think it will hold the weight of the tractor, and not allow the plate to pivot back any further and dig in.

Thanks for all the input.

  they should be angled these were built with the front wheels 42 inches off the shop floor with a slight angle to keep the front edge from digging in i personaly dont care for the pivioting padsd  when they hit the ground what is to stop it from digging in and then flipping back and essentialy chocking the tractor and probley breaking somthing and getting dangerious

Don't make them pivot. Like the others said if the back flips up you will have a anchor. Role the front edge up, weld them solid to where the back edge hits the ground first.  MACK
