The author studied for equilibrium and measured the increase of draft force and handle reaction by various weight loading and hitching point of tiller type garden tractor. The results were obtained as follows:
1. The increase of handle reaction has almost same value at no-loading and wheel weight loading.
But handle reaction decreases when the balance weight is transfered to front.
2. On various loading, the max. draft force is in order of balance weight loading 120cm>″90cm>″60cm>wheel weight loading>no-loading for each hitching point.
As hitching point drops lower and nearer to driving shaft, max. draft force increases.
3. The Kinematic equilibrium formula that contains driving moment Mf, is established by means of the above results.
4. By wheel weigt loading, the center of gravity shift lower position and the increase of draft force has the same value as its weight.
By balance weight loading, the increase of draft force is more than its weight. As loading position of balance weight is transfered to front the max. draft force is increased, too.
