A method and system for easily predicting a remaining lifetime of a hose are provided. A hose remaining lifetime prediction method and a hose remaining lifetime prediction system, for predicting a remaining lifetime of a hose 1 in use, include obtaining in advance, for a hose of the same type, relationship between use time of an inner tubular rubber layer 11 at a reference temperature and a physical property value of rubber forming the inner tubular rubber layer 11, generating a thermal degradation model for the inner tubular rubber layer 11, calculating, for the hose 1 in use, reference temperature use time being use time of the inner tubular rubber layer 11 at the reference temperature until a time of the prediction, and predicting the remaining lifetime of the hose 1 in use, based on comparison between the reference temperature use time and the thermal degradation model.

A retrofit assembly used to substitute a remotely controlled cylinder for a furrow closing standard spring on agricultural equipment. The retrofit assembly includes a cylinder mount including a cylinder mount tab and a cylinder mount fixture. The cylinder mount is connected to the furrow mount. The cylinder bracket 30 is mounted to the agricultural equipment. A remotely controlled fluid cylinder is mounted between the cylinder mounting assembly and the cylinder mounting bracket. A standard spring for a furrow closing assembly on agricultural equipment can be replaced with a remotely control fluid cylinder allowing the furrow closing assembly to be controlled remotely by the user.

A base assembly for a working machine. The base assembly comprising a ground engaging structure, an undercarriage connected to the ground engaging structure, and a connector for connecting the undercarriage to a superstructure that mounts a working arm. A drive arrangement is provided for moving the ground engaging structure to propel, in use, the base assembly and a connected superstructure. The drive arrangement includes a prime mover and a transmission and the drive arrangement is housed within the undercarriage. An electronic control unit (ECU) is provided for controlling the drive arrangement and/or the ground engaging structure.

An apparatus for attachment to a tractor the apparatus comprising a primary implement and at a first end, connections suitable to connect to the three point linkage of the tractor and at a second end, connections suitable to connect to the three point hitch points of a secondary implement.

Tubing bundle supports comprise body parts clamped around split rotatable sleeves. In one embodiment, spring mounted peripheral shoes and rotatable tubing bundle support sleeves allow metal tubes and tubing bundles to be routed inside a conduit in spaced apart positions and resistant to vibration. In another embodiment, split pillow block sections are clamped around a split rotatable sleeve. In an embodiment, the split pillow block support is held to a strut channel by a strut channel nut.

A support and guiding apparatus for feeder lines having a feed pipe for excavation devices is disclosed. The apparatus has a support branch and a plurality of crosspieces connected with the support branch which includes ring chain having a first and a second series of rings linked to one another in an alternate manner, defining a longitudinal axis (X); a plurality of spacer elements coupled to rings of the first series of rings so that they cannot slide. Each of the spacer elements has a seat that houses a ring of the first series of rings by orienting it in a substantially stable manner on a first lying plane, a second seat and a third seat opposite to each other that partially house the rings of the second series of rings linked to the one housed in the first seat by orienting them on a second lying plane transverse to the first lying plane, each of said spacer elements being arranged to prevent the longitudinal sliding between the rings and to allow the rotation of the rings of the second series of rings only on the second lying plane around a rotation axis perpendicular to the longitudinal axis of the chain and to the second lying plane.

A hydraulic system for a work machine includes a tank to store an operation fluid, a hydraulic device to be operated by the operation fluid, a control valve to control the hydraulic device, a first fluid tube connecting the hydraulic device and the control valve, the first fluid tube being to supply the operation fluid from the control valve to the hydraulic device, a second fluid tube branching from the first fluid tube and connected to the tank, a switch valve provided to the second fluid tube, the switch valve being to control a flow rate of the operation fluid, and an oil cooler provided to the second fluid tube between the switch valve and the tank.

A tubing assembly for a work vehicle includes a tube having a first end and a second end, wherein the first end is configured to fluidly couple to a fluid source. The tubing assembly also includes a fitting positioned at the second end of the tube. The fitting includes a first radially-expanded portion configured to engage a first side of a plate that is configured to form part of a chassis of the work vehicle, a threaded portion configured to extend through an opening in the plate, and a second radially-expanded portion configured to engage a second side of the plate to trap the plate between the first radially-expanded portion and the second radially-expanded portion, thereby coupling the tube to the plate.

A hydraulic fluid line coupling system is disclosed. The coupling may include a female fitting, a male fitting, first and second elastomeric seals between the female fitting and male fitting, and a lock nut securing the female fitting to the male fitting, and the lock nut including a plurality of threads.

A method of operating a digging machine, including damping the response of a boom hydraulic cylinder operationally connected to a boom arm and actuating a bucket hydraulic cylinder operationally connected to a bucket.
