Slow gears

Mike Lumley · Jan 30, 2012

Hoping someone can help out. Looking for phone number or name of person that listed slow gears in Red Power Nov-Dec 2010 issue. Looking for extra slow first gear for my Super C. Maybe somebody knows of someone else that deals with these gears.

I don't believe that a low speed first gear was ever made for a C. The parts info I have does not show one. It does show an optional high speed 7 MPH 3rd gear. A hydra-creeper option is shown as an option. I think that runs off the hydraulic system.

Hydra creep wont work, as i have taken off the touch control for pulling. Hoping someone can help? The ad listed slow gears and or ring & pinion.

You're running out of power before running out of traction when pulling the sled,right?You need to work on the engine,not the transmission.A member in our club has a JD B with low "Vegatable" Gears.It wont pull much-spins out sooner.you will have to put lots more weight on it,then that same weight will put you in a higher wt.class.Then you will right back where you started....Steve

Just the opposite. I have 13.6x36 tires. My ground speed to tire to track speed is too fast. I break loose when i start to load up. My air pressure is 8psi. HP isn't my problem, just thinking slowing it down may help??

Then you have too much power to the ground. Start backing off throttle as it starts to slip-not enough to stall it,rather enough to prevent spin out,then keep on working it as you pull.Gradually give it more throttle as the load increases.Try it.Thats the method I use.Wide open spins out lots quicker on the Super M.A little more'finess',more fun than just"balls to the wall".Steve

At the start of your pull you can drag the sled as fast as the tractor will go in that gear minus slippage on the tire. Pretty fast. as the pull continues, more load slows the tractor until it reaches a point that it has little forward motion, and the tires spin.
If you lower the ratio to reduce speed, the sled will be moving slower all through the pull. Because of this you will go a shorter distance. The inertia you generate on getting to speed is now less.
I believe a taller set of rears (not wider, just taller) will be better (you have no power issue, so putting taller tires on it will allow you to move the lead faster in the first part of the pull, and allow more of the grunt of the engine to work with less spin. When getting near the end of the traction throttling back to keep from spinning out will gain a few feet. the faster initial speed will gain maybe 10 feet.
I would go the bigger tire route first, then if no better, go to hand made gears. Jim
