 Topic: 190 puller
Posted: 19 Jun 2019 at 9:47am |
|
Hoping for some advice. Completed a-pump installation on 190. Works great however when I pull, I'm getting a crazy bounce. Some ole timers said not enough tire pressure, I'm running 13 psi on Good year dynatorques. 18.4r38. Some said try dropping hitch 1/2" and also could be clutch. I'm running an Atlas 11" double disk. I use 7th gear.
Any thoughts would be appreciated.

My thought's are, to much pressure.
More air pressure will give you less of a contact patch and you'll spin earlier. Not good.
Less will give you, more contact and have less energy to bounce. I believe that the only way to start a bounce, is to have slippage, first.
Sometimes, problems can be diagnosed with extremes, see what happens at 8 lb.

I would say try less pressure in the rear tires, a flat ball doesn’t bounce, I have better luck with my 200 with the tires softer and have enough weights to move around to balance it out , do you have a center weight bar , weights in the middle seem to do better, just my opinion

Weigh the tractor as you have it. If it weighs 6000 lbs, I would try 2000 lbs on front wheels and 4000 lbs on the rear wheels AS A STARTING POINT. Also, shift it into road gear and see if the clutch slips or kills the engine. That will diagnose that issue. Sounds like you are too heavy on the nose.

I run 13-14psi and seems to work good. Firestone 23 degrees. Narrow tire stance with tires an inch from stock fender location. 190 a-pump 7th gear also. 6500lbs, I run with no weights and no bounce. 7500lbs 3-5 weights on front the rest on the back. Before I removed power director had a lil bounce off the line up to maybe 100 foot line but none on the other end. I'd try different tires.

Yup I dont run PD either. I'm going to try hitch height alittle lower first. I'm weighted pretty much as Dr Allis suggested.

In the video, it looks like you have 250-400 lbs on the front ?? Too heavy in that run as it never picked up the front wheels once.
