I don't get it. I have a shuttle and don't need more hands for loader work.
There is a foot peddle for the throttle.
If working a shuttle lever is as difficult as you claim, then why do most commercial front end loaders and backhoes use a shuttle lever for forward/reversing ??
how does anyone EASILY manage the wheel, the fel and the shuttle? The throttle may or may not be on the floor.
I've driven tractors for over 25 years, 2-3 or more times a week, where I could use 3 hands to steer, shift, work the fel. I only had a handle throttle.
I did it A LOT and I managed. It becomes second nature after a while. I'm not saying it's not possible, just that it's not easy and convenient. It's doing something the old way, where everyone accepted it, as it was the way that it was done.
It takes a new-to-hst person about five minutes with an FEL and a pile of dirt to understand the concept of backing off the pedal when you drive into the dirt pile.
Now that I have an HST, it is SO much easier. I would never go back.
I have to agree with MtnViewRanch about the speed thing. I run my 3016 at about 1500 RPMs and it does everything I need it to do. If I want to go faster, I press the GO pedal. It goes along well with it in H range. I've been working with it mostly in M range and once I wanted to see if I could uproot a small tree so I put it in L range. I don't generally adjust the throttle.
I didn't have a tach on my previous tractor and judging by the sounds of each, I think the other was usually running about 1500 rpm's as well.
To each his own. I'm just telling it from my personal POV.
