Have to agree with the above, I grew up with a four lever Ford at our house, the first time I used a two lever, I thought it was the greatest thing ever invented. As for your question, the "joystick" you see on bigger equipment is electrical, running solenoids that operate the valves, if you think your toys are expensive now,! add that setup and you'd have to live in your tractor. Most full size tractor-loader-backhoes don't even have this setup due to the cost. It doen't hurt quite as bad on a several hundred thousand dollar machine. You are slowly starting to see the smaller Japan built construction equipment with them, but for hoes your size, I don't think it will ever happen. When I was learning as a kid, my Dad wouldn't throttle up the tractor very high, he made us learn that the teeth will do the work if you point the bucket right and let them cut. Running at a high rpm is good, but, as you are learning, you tend to us only one lever at a time, and with the engine wound up it's much harder to keep from slamming the hoe around. (swing was always the worst!) I would learn to work on smooth and fluid motions first, then more on working on all the actions at once, which takes more oil and slows and smooths things out a little. Next time you see a true operator running a hoe of any type, stop for a moment and watch how fluid his motions are, very little wasted motion and lots of work happening. You see less and less of this as all the young "hotdogs" are starting to run equipment.
