Here are a few possibilities. 1) The drive belt from the engine to the transaxle (rearend) has come off or broken. 2) The brake on the transaxle is stuck and keeping the brakes locked up. 3) There is a problem inside the transaxle. 4) A pulley or tensioner that keeps the pressure on the belt has broken or needs attention. 5) The linkage from the handle to the transaxle has become disconnected or out of asjustment. You will need someone to watch the belts, pulleys etc while you try to operate the mower to determine what is going on.
For stability and traction
A "mechanical front wheel drive" tractor has front-wheel-assist which means that not only the rear drive wheels pull the tractor ahead, but the front wheels also pull the tractor.
It is more difficult to steer with big tires, they are smaller so they are managable, also the weight on a tractor and traction is needed in the rear
when the wheels are larger the tractor appears to be going down hill making the load easier to pull. Much better for traction especially in mud and soft soil.
When you turn the front wheels, they skid sideways as they turn. The skidding wears rubber off the tire.
As the tractor pulls plows or other things the weight gets pulled back onto the rear wheels, to carry that weight and not sink into the ground they need to be large.
its to do with gearing think about having small wheels on the back they.d never push the big wheels
Either a nut on the axle or with a C clip against the outside hub of the wheel.
No, you can adjust them properly on the right side just before the rear diff lock pedal.
It is what the rear wheels bolt to.It is what the rear wheels bolt to.
A tractor works basically the same way your car does except for at a larger scale and with more power. A tractor also runs on diesel, which powers a 4- to 8- cylinder engine which powers the rear wheels/PTO/hydraulics which make a tractor the useful piece of machinery it is today.
