Had to lol on that one !
I have been using a john deere riding mower for 8 yrs. , already had to replace the transaxle , I don't think the brake system was adjusted right from the factory , and put undue stress on the whole mess. When I put the new one in , I had to adjust the brakes way down compared to the original , shift/stops better than new--------
Next time I`ll be looking for a zero turn , probly a 40/42. Would love to find a single blade 40 '' , when they get some age on them, the single blade will do a prettier job than a dual blade. jmo--I`ve had both.
