摘要： A flexible guard for preventing rocks and other debris from becoming trapped in the hollow area between the lift cylinder mounting lugs and then being crushed by one of the angle cylinders when the bulldozer blade is angled. In a first embodiment, the flexible rock and debris guard is fitted around the forward end of the lift cylinder mounting lugs on the bulldozer C-frame. It deflects away from the lift cylinder lugs the debris pushed against it by the retracting angle cylinder when the blade is angled. The rock guard has the additional advantage that the normal lubrication of the lift cylinder rod eye can be accomplished without its removal. A second embodiment of the rock guard includes a solid block of rubber or plastic that fits in the hollow space between the upstanding lift cylinder mounting lugs, and it has deflecting surfaces and flexible end portions permitting lubrication of the lift cylinder rod eye thereby providing the same general features as the first embodiment.
摘要翻译： 一种灵活的防护装置，用于防止岩石和其他碎屑被捕获在提升缸安装凸耳之间的中空区域中，然后当推土机叶片成角度时被其中一个角度缸压碎。 在第一实施例中，柔性岩石和碎屑防护装置安装在推土机C-框架上的提升缸安装凸耳的前端周围。 当叶片成角度时，它偏离提升气缸突出了由缩回角缸推动的碎屑。 防护罩具有额外的优点，即可以在不拆卸提升缸杆眼的情况下实现正常润滑。 岩石防护罩的第二实施例包括固定的橡胶或塑料块，其装配在直立提升缸安装凸耳之间的中空空间中，并且其具有偏转表面和柔性端部，从而允许提升缸杆眼的润滑，从而提供相同的 一般特征作为第一实施例。

摘要： First and second tractors are connected by a coupling device in a first row, and a third tractor is disposed in substantially parallel relation thereto in a juxtaposed second row. An implement assembly is connected to one of the first and second tractors and to the third tractor for moving material obliquely away from the normal longitudinal direction of working movement of the tractors. Preferably, a second implement assembly is connected to the other one of the first and second tractors and to the third tractor for similar operation when the triple tractor assembly travels in a reverse direction as a unit.

摘要： A bulldozer blade mounting assembly is provided for mounting a bulldozer blade on the front of a tractor. The mounting assembly includes a push frame connected between the tractor and the lower portions of the blade. A combined cushioning and stabilizing linkage assembly is provided with a link extending diagonally between each push arm of the push frame and the upper rear corner portions of the blade. The stabilizers on each link are interconnected with a closed loop hydraulic system so as to ensure that any deflection in one link must also occur in the opposite link.
