thanks  on the 1950

It only smells   like when I am turning square corners--- *(brakes and clutch applied abit)    I  did put my nose  on that vent--  nothing there ... 

we did have a bit of problems shifting from the 1000 to the 540 this time... could we have??
or  is it like I thought  maybe the belts on the mower???   the smell you just cant  locate  -- in a hay field  thats mostly  weeds  and you have  alergies  and athesma...
