[AT] weighted tires or not???

[John Hall]

All this talk about wide front vs. narrow front got me wondering about 
something else. Are tractors with fluid filled rears more stable on 
hills or in quick maneuvering on uneven ground? The reason I ask is that 
I replaced the tires on a IH utility tractor we have had since new (1972 
454). It has over 8,000 hrs and we have always had weighted tires on it. 
Well I didn't have time to fill the tires with fluid before I began 
using it this spring. So far I am liking the less weight for treading on 
wet spots in fields. I recently reduced the air pressure (it was at 25, 
I dropped it to 20) because it was shaking me to death while spraying a 
field. The only time the loss of weight has been an issue is moving one 
load of hay--it was digging pretty bad. We do all of our bushogging with 
this tractor so there are quite a few banks and hillsides to get into. 
Wonder if it would be more stable with the fluid in?
