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.
