Thanks for the lesson Reed.....so it is a separate SS gear box? I have never seen an arrangement like that. The engine/bell housing/trans has been bolted together on all other tractors that I've seen and the shuttle arrangement was encased in the trans housing.....or I assumed this to be the case. Iseki's are certainly full of innovation. I've got to be honest though, the first thing it makes me think is, I don't know if I'd put a front end loader on it.
Since Reed is familiar with Landhopes, he'll have to explain it's operation ( some shuttles work differently than others) but the shuttle shift is the lever on the left side of the steering column. It is probably marked with forward, neutral, reverse. It allows for fast gear changes between forward / reverse and is very handy when doing certain types of work...especially using an end loader. Every tractor should have shuttle in my book. All of the equipment I have personally used have allowed for using the shuttle w/o using the clutch and while moving. I think some require the clutch to be used though and I'd say it's always a good idea to be stopped before engaging the opposing gear.
I will have to back up on one statement that I made earlier now. I know from reading about equipment that some shuttles use a separate hydraulic clutch.....so when I said I've never seen/(heard of) of a hydraulic clutch on a tractor...that's not necessarily true.....they're just in the trans, I've never personally seen one or really understand how they work.:confused2: In any case, I didn't think about that or think it applied here.
I have two separate levers for gear selection that both connect to the gear box directly under the seat. Sitting in the seat they are on my left side. The lower one by my left knee is h pattern R,1,2,3 and the other one located left side by my hip is also h pattern 1,2,3,4
