Confused about Supersteer

spencer200 · Apr 25, 2003

yeah that would be supersteer. I have not seen that happen with all the tractors we sell I am just surprised thats all. Maybe the weights he had where not newholland. I dont know it just sounds odd that it hits.

When I got mine I got two weights and if u wanted more there is an extension weight bracket to let u use the max amount (I think it is 5 or so).
He needs to put the extension on the 45D.
My dealer had it in his spec book.

I stopped by my dealer this morning to pay a bill, and did a little more drooling while I was there /forums/images/graemlins/crazy.gif. It appears tractoritis is not fully cured just by buying one.

Anyway, they had 3 TC45Ds on the lot, 2 with SS and one with Standard steer. All three had R4s, and all 3 were parked with the wheels turned hard left to demonstrate the difference between SS and standard. With the R4s, they would not reach the weights - should clear by 1-2 inches. The standard steer wheel does not go forward far enough to reach the weight bracket at all, and the stop keeps the tire from rubbing the engine cowling.

So, it appears the problem might only occur with agressive R1s, which must be 2-3 inches larger in diameter than the R4s. Turfs should not be a problem, either. My friend didn't say anything about ordering larger than normal R1s, but I guess that is possible, also.

I will mention the extension bracket, in case he is not aware one is available. Thanks for the tip.

Sitting here now, waiting for the dealer to deliver my 1520, which they just serviced...supposed to start raining tonight and tomorrow /forums/images/graemlins/frown.gif /forums/images/graemlins/frown.gif = reduced seat time this weekend.

( So, it appears the problem might only occur with agressive R1s, which must be 2-3 inches larger in diameter than the R4s. )

Casimir, that's a good point. I was thinking in terms of width, but the extra height of an R1 would equate to extra "reach" towards the center of the tractor as the axle swings forward. I know the TN's clear this fine, but my dealer doesn't stock many TC's with R1's, so I have no way to verify.

We've had good rain here for two days. I'd say we're just about up to zero seat time this weekend. Unless I need to break out the "fear"-wheeler. /forums/images/graemlins/smile.gif

Later,

That would make sense to me that it is happening with ag tires we have never sold a supersteer with anything but turfs or industrials so i have not seen one with ags turning I missed that when I read your post the first time.

I found tire sizes for class III
8-16 R-1 30.5" OD
10-16.5 R-4 30.8" OD
Plus the R-4 is 2.5" wider tire.

That 18" is an interesting number but remember it is the inside diameter of a circle. You still have the entire remainder of the tractor making the circle. A SS tractor will complete a full turn in under it's wheelbase with brakes. Here is some of the text from a post I made in the Pricing Buying forum Having had a larger tractor (TN75) both with and without SuperSteer I can tell you that there is no comparison in turning radius. I went to New Hollands web site to get some numbers as I was confused by some on the numbers in the previous posts. The NH TC29 has a wheelbase of 63" and turns in a 102" diameter circle with brakes. Supersteer TC29 has a wheelbase of 72 and will turn in a 60.5 in circle. TC 45 has wheelbase of 73.5" and turns a 127" circle. TC45 supersteer has 83" wheelbase and turns a 81" circle (again less than it's wheelbase)

Again as I've done in previous posts I would caution the use of SuperSteer if you will be doing much loader work since it can make the tractor quite unstable if you have a high load when the axle is rotated.

Hope this helps clarify the issue some. To keep it simple just remember the tractor with SuperSteer can spin in less than it's own wheel base. If you haven't driven one it is worth a trip to a dealer to try one out.
