The next problem to fix will be loss of ground due to limited or no vertical travel of the wheels without traction tires.
I removed all the traction tires on my 44 tonner. Eliminated the other cause of stalls. Plenty of pulling power for my applications without traction tires.
I wish MTH/ATLAS would offer geared axles without traction tires part # DC0000024. I have had 6 axles on back order since February 15, 2022.
Let’s go MIKADO.
