Källbunden jämförelseprofil med separat originalunderlag; ännu inte en fullständig modellguide.,DLG full report directly names a 4755 Powershift with mechanical front wheel drive (4WD), Nebraska Test 1621 / OECD 1236; tested unit serial is report-scoped.,Do not merge this MFWD Powershift test with 2WD, Quad-Range, another 4755 transmission, or adjacent 4955/4760 material.,The DLG report’s “1st Serial number” is reproduced literally and is not treated as a dated production start, model year, or full PIN range.,Deere June 2016 capacities are approximate shared-group cells; June 2016 is not the tractor model year. PST rows with/without MFWD stay separate.,DLG PTO table values are PTO output, not crankshaft engine power; no rated engine kW is inferred from them.,The DLG p.16 two-hour maximum-power row prints 36.89 L/h alongside 9.61 gal/h; the pair is not conversion-consistent. Preserve both literal cells and do not silently correct either.,No sales-market, Swedish availability, pricing, 2WD/QRT test results, full-guide status, or photo is proposed.
