Stupid question #1934 6 speed vs 3 speed

Recommended Posts

donmoore1904

The thread on changing a 3 speed to a 6 speed (what I can infer from the discussion) leads me to finally satisfy my curiosity and ask what the difference is.

From what I read, it sounded as though a 6 speed might be a 3 speed tranny with pulleys added. Please forgive me if I am way off base, but is this the case or is there actually a 6 speed tranny?

If you are familiar with folks using a large (8" or 10") pulley on the early 3-speeds, to slow them down for tilling...well, that is exactly what the 6 speed tractor adds, but in such a fashion, that both size pulley sets reside side by side. Each has it's own belt, and shifting from 'Hi' to 'Lo' is done by applying the clutch, and engaging one of the 2 belts with the range selector. Quite simply, it moves the idler/tensioner pulley from the 'Hi' pulley set, to the 'Lo' pulley set, and vice versa.

It's actually a nice, reliable setup. Plus, if you happen to toast a belt, you still have one to use to get you back to the garage! ;)

I should note, for anyone in a similar, single-belt situation with a 6-speed tractor...if you find yourself at the garden and begin to run low on beer, and have no intention of manually moving the belt over to 'Hi', leave EARLY on your tractor, to return to the garage for replenishment. It takes a while to get there in 'Lo', and you may run out during the trip. Another option is to bring extra beers to the garden...but they may get warm, and that presents an entirely different problem. You could also bring a cooler, in some creative fashion, on or behind the 6-speed...but if you have to take a cooler to till the garden, you have bigger problems than I can advise on.

I hope this helps someone. Mark? Tim? Ray? Mike? :Q

Not the best pictures, but hopefully this can clear it all up;

My current 3 speed; one set of pulleys and one belt.

IMGP7039.jpg

The 6 speed setup I'm going to; two sets of pulleys and two belts. A low speed kit run in parallel with the normal set. A lever moves the idler in and out to apply tension to only one belt, thereby selecting the range.I bought my 3416 as a shuttle with a broken axle tube and missing diff. I swapped in a 3410 3 speed as a stop-gap measure until I either repaired the shuttle (it actually came with a brand new tube, just not installed, but no diff), acquired a hydro, or found some other option. I acquired a vickers unit to put in, but right at that time my father's 3414H started acting up and it made me weary about putting a pump in mine, and I thought it may be best to keep it around as a potential donor for his. [His 3414H is pristine original; previous owner used it to cut something like a 25' x 25' piece of grass in the city!] Soon after that we picked up a 7013S that had a busted shuttle, added that to a previous 7117 that had a bad bearing in the planetary of the shuttle and I started getting weary about shuttles. Meanwhile the 3 speed has been bullet proof while the rest of this has been going on. Enter this most current deal, a friend who bartered for a 710 6 speed that he's going to give me for working out some minor issues on his 7010 and I can keep the bullet proof 3 speed while adding the least possible number of 'things that can break' to the setup and get a low range for tilling and deep snow and still keep a high range for moving about. None of that is to say that I have a bad opinion of shuttles or hydros. I've acquired a few of each and they work well. I just want to keep this one as easy to work on as possible as it's my worker and the most likely for me to push too hard and break.[sorry for the long-winded post]

So Josh,

In other words, the moral of the story is to have a sippin beverage like Scotch instead of beer? ^

Awesome replies, and a picture is worth a thousand words. Thank you for the education.

And now for an associated question-->

In the 7010 manual for my 3 speed, it has a chart (@3600 rpm):

------Standard---Low Speed Kit

1st----1.5mph-----.96mph

2nd----3.5mph------2.3mph

3rd----5.8mph------3.7mph

Looking at Brian's picture, it looks like the outboard front pulley is smaller than mine. Could it be that the 6 speed ground speeds are similar to those in this chart? In other words, the 6 speed adds a lower range that is the equivalent of the Low Speed Kit? I assume that the Low Range Kit for a 3 speed tractor replaced the front pulley with a smaller than stock one?

id="quote">If I'm not mistaken the "low speed kit" for a 7010 is just a larger rear pulley, new belt and belt guard.It does give close to the same speeds as a 7010 6 speedManual 6-speed transmission:Forward speeds .7-6.1 mph
