摘要： PURPOSE:To suck lubricating oil without contaminating the oil with air by forming a horizontal inlet passage directed lengthwise monolithically to a case bottom positioned below a fixed level holding point. CONSTITUTION:When a tractor is tilted forward, an oil level 89 of lubricating oil of a transmission is tilted forward. At this time, the depth of lubricating oil near a rear oil inlet port 23 becomes shallow. However, since the rear oil inlet port 23 is away from a vertical line of a fixed level holding point 88 compared to a front oil inlet port 24, the rear oil inlet port 23 is not exposed above the oil level 89. Further, on the bottom of an oil inlet chamber, most of lubricating oil to be sucked flows from the front oil inlet port 24 into the oil inlet chamber, and the inflow of lubricating oil from the rear oil inlet port 23 is not large so much. When a vehicle is tilted backward, the depth of lubricating oil near the front oil inlet port 24 becomes shallow, and the front oil inlet port 24 is exposed above the oil level, but since a forward opening of the oil inlet chamber is retracted to a rear end edge 25a of a partition plate 25, contamination of lubricating oil with air can be prevented.

摘要： PURPOSE:To miniaturize and lighten by spline-fitting to the first idler gear on the first idler shaft a shifter gear which can be spline-engaged disengageably with the second idler gear on the first idler shaft while meshed disengageably with an idler gear on the second idler shaft. CONSTITUTION:One subspeed change system is constituted by sline-fitting to a shaft 28 each high and low speed driven gear 38, 39 (first, second driven gear), rotatably fitted to the gear wheel driven shaft 38 (output shaft), and a shifter gear 37 disengageably spline-engageable with these driven gears. While the other subspeed change system is constituted by spline-fitting to a low speed driven gear 40 (first idler gear) on a shaft 29 a low speed shifter gear 43 which can be disengageably spline-engaged with a low speed idler gear 41 (second idler gear) on the intermediate shaft 29 (first idler shaft) while disengageably meshed with an idler gear 45 on a front wheel drive shaft 30 (second idler shaft).
