Chevy C60 Kodiak -- what is the speed in 2nd Gear low--

[Tom McKenna]

Anyone out there know how fast a Chevy C60 Kodiak will go in 2nd gear? This truck has a gas engine and 4 speed tranny with the hi/low shifter.

I bought this truck with a lime bed. I put the lime bed on a tandem axle trailer thus converting the lime bed to a pull type.

I'm told the previous owner ran the truck in 2nd gear with the gas pedal smashed to the floor. I need the speed to figure out how much lime I'm putting on / how fast to run the tractor

I think there are alot of unknown variables. Truck gear ratio for ground speed and then how fast did the truck PTO run compared to a tractor pto ?
 

[Tom McKenna]

PTO speed is 540 -- same as the tractor.

I have no idea what kind of a rear end the truck had. It doesn't run and I scrapped it.

Any general idea on speed?
 

[Mike M]

I really have no clue as to how fast they run ? I just knew there will be varibles needed to figure it out.
Any locals got Chevy grain trucks ? If so go drag race them with your tractor and match up the speeds. Got to be better then a guess.

The C60 we have on the farm is a 4+2, with a 350. It has a 6:1 ratio rear axle. It dosen't even register the speedometer until you're in 3rd in low, (approx. 15mph), so I'd guess in the 7-10 MPH range?

Of course, the truck you had could be totally different. But you knew that. good luck! -Andy

PS, As I think about it, That guess is for only maybe half throttle. The only time more throttle is needed is when trying to actually get somewhere with the truck. Hauling grain, or empty, I'll be around 3/4 throttle to do 45-50 with it. I usually only hit 35-40.

That being said, with the throttle WFO, I still think 15 mph is being overly optimistic with the truck I'm referring to. I'll stick with the 10 mph guess.

Why not just figure out how fast the apron will be travelling in your present setup in feet per minute... then measure the desired cross section of the gate... from there calculate a volume per minute. Convert the volume to pounds per minute. Once you have that you can easily figure your spread area based on width and travel speed...

Tom,

I could not make out the brand name on the spreader in the picture. It looks fairly new. Is the web chain ground driven or PTO driven? If the web is ground driven it should be easy to figure out from the instructions often bolted somewhere on the side of the bed.

If you can find a tag with a make and model number you should be able to get set-up and operating instructions directly from the manufacturer or by searching the internet for the instructions or a dealer's name.

From the picture it looks like you've already used it, why bother asking now? -- Just kidding!

It really does depend on so many things. On a "fast" geared 4x2 in low I had one that I wound out to 15 mph (at 3200 rpm) every time I shifted her. My truck now (a slow 4x2) wound out to 3000 rpm is 5 mph. Most Kodiaks aren't geared that low - that's for the old babies. 15 mph is a little tall, but that setup only put me at 50 in fourth low (New Process four speed). If he really had it wound up good (I think redline is just under 4000 on them) I would say 12 mph is a fairly safe bet.

It would be easier just to do the math like someone said and then do a sample box.

i would get in road and drive in 2 wide open and time it over a measured distance. then drive tractor to achieve same speed.

This will take a little math, cut a 3x3 square of anything flat,cloth,cardboard,plywood and lay it in the field(cloth stake it) and drive over it at whatever speed you thing is right. Then weigh the lime and you will know how much you are spreading on the 3x3 and multiply it out to an acre.

Borrow an iphone from your kid/grandkid/friend. Everyone installs a spedometer/odometer app, or use the GPS mode.
Or pull the Garmin from the car.
