I am inclined to presume you have recently acquired this tractor? It sounds like this tractor has a hydrostatic transmission (fluid drive). I'm pretty certain that the lever under the seat is the "free wheeling or bypass" control that allows you to manually roll the machine when the engine is not running. This is a very useful feature for moving the machine to a parking position for storage in close quarters, or any time the tractor must be moved and the engine does not run. The pull knob on the dash is most likely for engaging the parking brake lock. To check for this, press down (could require great effort) on the brake pedal while pulling out on the knob. You might be able to hear or feel the locking pawl "snick" into the lock positon. Continue pulling on the knob while you take your foot off the brake and the knob should remain (somewhat) in the pulled position and the parking brake should be locked now. To release the parking brake, push down on the brake pedal without touching the dash knob. When the brake pedal goes down far enough, the knob will disengage and the parking brake is now released. I also must guess that this tractor DOES NOT have a transmission directional control lever (on a fender perhaps) but instead uses a foot pedal control for forward and reverse. With the foot pedal directional control, you generally have to push forward at the top edge of the pedal to go forward and push forward or down on the bottom edge of the pedal to select reverse. Taking your foot off of the pedal should return the transmision to "neutral" AND apply the automatic dynamic braking afforded by hydrostatic transmissions. It is this "dynamic braking" feature that the lever under the seat defeats when you need to move a non-running machine. If this is your first tractor or your first hydrostatic transmission, you have a bit of learning ahead. Take note that pushing lightly on the transmission pedal will produce slow going but a heavy foot will result in jack rabbit starts (in either direction). It is advisable that you get the machine into an open area to practice and "play with" until you are comfortable with all aspects of operation. I hope some other members will jump in here with more specific details in regard to your exact machine. Be careful out there.

Joanne, Suckers will grow just as the mother plant. I have some that have developed leaves that were not true and were removed and some have not. If you have not gotten the entire sucker from the plant, you should be able to see the bits that are left. You can rub them out with a pencil point. If there is some of the sucker left, the sucker will sometimes sucker. If you want the sucker for another plant, let it get a bit bigger so it is easier to see when you remove it. If you are not sure if you have a bloom or a sucker, again wait for a few days and it will become obvious. I hope this helps! Linda

Sunflowers are simple to grow. They are not picky about soil.I give mine a fair amount of water, and they grow fast. They were planted from seed about 6 weeks ago and are now about 5 ft. tall. You should have no trouble starting them now in zone 7. If you wait until next year, I'm sure it would be best to start them indoors. Good Luck!!
