Embarrasing moment at tractor pull

when you hook to the sled in 4000 lb class and cant move the slid in any gear for spinning.

Did you try taking off at an angle?

Wrong tires (tread cut) for the track or too much air pressure.

Happened to me, just sat there and spun, lucky I was the first puller and they shortened the chain 2 links and I was able to move it for a full pull. Chain length matters!

Pulled with  my 7040 at the local fair .. went to hit the high button and the old gal  froze till i hit the low button again ..  embareassed

Well Pankey, you make me feel a little better for this week's pull.  I did ok last week in the 4500 lb. class, but not great.  I am weighted up this week to go in the 6000 lb. class, so it's either gonna be really good or really bad.   I had one pull like that four years ago, my first one.  Spun from the very start and finally did get going but ended up second to dead last in my class, last being someone that broke something.  I almost ended my pulling career after that first pull.  I guess that's the fun thing and upsetting thing about pulling is that just when you got it figured out, it throws you for a loop. 

Finishing second when everyone else tied for first is real embarrasing.

I have looked over some notes and talked with some friends. I had only pulled the diesel rear twice before blowing the 310 ci motor up. This new motors increase in cubic inches and 1 point increase in static comp. ratio is definately making more torque. that along with the mechanical torque of the slower gear . Suprised me or was something I hadnt thought about much untill this week. Engine saturday had a verry light tune in it  but will spin the wheels about four feet in high gear across the field with nothing hooked to it when called on with throttle. Its time to weight it up or go back to the higher ring gear or back the cam  up  a degree or four.
