TO 30 turns over slow

I have had this tractor 20 years. I have always had a 12v battery in it. The starter hits real hard and I have had a problem breaking nose cones if it isn't timed nearly perfect. I bought a 6v battery for a 8n I'm working on. I decided to try it in my fergy. It turns over fast enough to start but I'm not to impressed. I haven't been around many 6v batteries. Is this just par for the course or do they actually turn decent?
 
millions of cars and trucks and tractors were started very well on
6 volt batteries. But 6 volt is not as forgiving as a 12 volt. connections need to
be super clean, and starters in good shape. They are rebuildable.
now if you apply 12 volts to a 6 volt starter, it will turn faster and start quicker, and
will also break nose cones and fry the system if you are a bit careless.
 
I realize that they work fine and maybe my question isn't worded right. What I need to know is how fast a properly working 6v turns in comparison to a 12v system? Mine is slower than I'm use to but that could be normal for 6v?
 
6V or 12V?
Difference? Basically 12V spins twice the speed.
Breaking nose cones? Ring gear looks like what?
 
It hasn't broke nose cones in a long time but it hits hard. I happened to be buying a 6v battery for the 8n so thought I would see how it spun the Harry. It seems slow but I guess it's the way 6v is. It's about the same in the 8n. The fergy will start pretty easy with a hand crank when everything is right. I found that out when I was fighting nose cones.
 
A 6 volt system turns over quite slow compared to a 12 volt system. But like Kris said, that's what we had for years and years back in the day and the vehicle started as long as everything else was in good working order.
 
Change both leads from battery to OO Gauge.
Removed poor Ground / Earth strap..go directly to Starter...
My 6 Volt Ferguson starts perfectly...Starter spins engine over ......:)
My 6 Volt Ford 2- N starts perfectly...Starter spins engine over ......:)

I believe I rerouted the ground wire already. I usually do anyway. Not sure what wire size i have. The tractor doesn't run very often so i dont plan on spending much right now.

Thank you for answering my question directly! That was what I was figuring but needed clarification.
 
I just installed 2/0 battery cables custom made from a cable web site as none were available locally. They will make up red or black any gauge with any ends you need any length. The starter spins the engine right over. Not as fast as a 12 vol. These old Ferguson's have up draft carbs, which take a few more engine turns before they light off because the carburetor is a bit more distant from the combustion chambers than typical down draft set up.

What I have noticed, if tractor sits for a while, a week or two, it turns over rather slow the first few crank revalutions, and has once stopped turning while engaged and than continued to crank. I think this has something to do with dry cylinder walls. The second start spins right over. If it is started the next day, it spins right over.

My tractor sat for 18 years, and valve train was rusted tight not able to move. Engine was close to being stuck, so I suspect it may still have some nasty spots where rings were sitting for all that time which may have something to do with that occasional drag-down of starter performance.

Get those fat cables, and reduce voltage drop.
 

There are no longer any off the shelf battery cables.
wjajr.
if you could post the information for the place that made your custom cables it would give an option for those needing quality cables.
I'm going to buy some welding cable and make mine for my 203.
There is a lot of good information in this thread about cables.
I recently read that insufficient battery cables causes premature starter failure. Its basically the same as if you run a 100 foot extension cord to a air compressor. It fry's the motor With a starter its killing it slowly with each start. The wire has to be able to carry the amperage the motor needs to work or the motor suffers damage.

Four years ago when I got my TO30 running after sitting for 18 years, I took both starter and generator to a local rebuilder. They went through them replaced whatever was needed, bushings, brushes, probably turned the armature, cleaned out any rust, and painted the exterior. That crossed off two problem child's of the list of things to repair. Yeah I know, one can overhaul these things at home, but they stress test them, probably mega the winding's. It's what they do all day long.

A draggy starter can have bad brushes, corroded armature, dry bushings, and other problems from old age, as well as voltage drop from under sized conductors supplying the amperage, poor connections, and a half dead battery. The there could be mechanical problems with engine, and or ring gear.
