TRANSMISSION
The John Deere 4044M offers a versatile 12F/12R PowrReverser transmission, enabling smooth forward/reverse shifting ideal for loader and transport applications, while the optional eHydro provides infinite variable speed for precision tasks. Its multi-plate wet disc brakes and hydrostatic power steering enhance operator control and safety, particularly in challenging terrains or during complex maneuvers. However, the absence of a creeper gear may limit its effectiveness in extremely low-speed applications like detailed earthmoving.

TIRES
The John Deere 4044M tractor exhibits versatile tire configurations, promoting agricultural, turf, or industrial applications depending on the choice of 8-16 (farm), 27x10.5-15 (turf), or 10-16.5 (industrial) front tires, and corresponding rear options. Its front tread width of 148.1 cm and rear spacing of 137.2 cm enhance stability and maneuverability in tight spaces, making it suitable for diverse field operations. However, careful selection of tire types is crucial; turf tires minimize ground disturbance, while agricultural tires provide better traction on uneven terrain, impacting performance based on specific operational scenarios.
| Front | Farm - 8-16/Turf - 27x10.5-15 or 27x12LL-15/Industrial - 10-16.5 |
| Rear | Farm - 13.6-28/Turf - 44x18-20 or 22.5LL-16.1/Industrial - 16.9Lx24 |
| Front tread range | 148.1 cm/58.3 in. |
