kneedeep said:Tractor mechanic told me that the dual brakes on a Ag tractor are for keeping the tractor following the rows whether straight or curved. Tractors tend not to turn with heavy ground engaging equipment like planters and cultivators. Thus, 'guiding' the tractor using the brake pedal to follow the row. He also stated that locking the brake to twist the tractor around eventually will damage the brake, or worse yet, break a axle. Proper way is to stop, raise equipment and turn even if you have to backup.
I bought a JD 950 years ago that the left brake was completly worn out from the old farmer 'spinning' the tractor at the end of the garden row. Everything was worn or broken on the left side and the right side had minimum wear. The tractor was only 4 years old and he planted about a acre garden.
Just my :2cents: worth
There is a world of difference in a 950 and a Ag tractor.
