A tractor linkage arrangement (10) to attach work equipment (20) to a tractor comprising a subframe (100), which is to be attached to a tractor chassis (11), comprising a first (103), a second (104), a third (105) and a fourth fixing point (106), a first support (101) comprising a first and a second spindle opening (107, 108), and a second support (102) comprising a third and a fourth spindle opening (109, 110), further comprising a first lifting arm (140), which is pivotally attached from its first end to the first support (101), a second lifting arm (141), which is pivotally attached from its first end to the second support (102), wherein the first lifting arm (140) is comprising a first lifting pin (142) on one side of the first lifting arm (140) and first gripping pin (144) on the other side of the first lifting arm (140), and wherein the second lifting arm (141) is comprising a second lifting pin (143) on one side of the second lifting arm (141) and a second gripping pin (145) on the other side of the second lifting arm (141), and a work equipment adapter (120), which is to be attached to a work equipment (20), the work equipment adapter comprising a first link arm (121) and a second link arm (122), a first, a second, a third and a fourth spindle opening (123, 124, 125, 126), wherein the first link arm (121) comprises a first grab (129) and the second link arm (122) comprises a second grab (130), wherein the first gripping pin (144) is to be fitted to the first grab (129) and the second gripping pin (145) is to be fitted to second grab (130).

A working vehicle includes an inertia detector to measure inertia information of a vehicle body, a rear axle supporting a rear wheel, and a transmission case rotatably supporting the rear wheel. The inertia detector overlaps with at least a portion of the transmission case in a plan view and is capable of accurately measuring inertia information when a vehicle body changes attitude.

A front attachment lift mechanism includes a front hitch weldment connectable to a lawn tractor frame and having a pair of side plates for supporting a front attachment. A hitch arm extends upwardly and rearwardly on each side of the frame. A rear weldment includes a pair of rear brackets connected by support bars to each other. Each rear bracket has an upper portion connectable to one of a pair of lift arms on a lawn tractor, and a forward end extending forwardly and downwardly from the upper portion. A wireform assembly is connected between each of the hitch arms and the forward end of one of the rear brackets.

An adapter bracket assembly is configured to allow a tractor to operatively connect to a different, otherwise incompatible utility component. The adapter bracket assembly includes an attachment member configured to securely connect to an attachment bracket that is compatible with the tractor, and a component-engaging member that is configured to securely connect to the different utility component in order to securely and operatively connect the different utility component to the tractor.
