Orchard tractors have been special models for decades, and New Holland has introduced three models in the T4000F series, all with tight turning circles and slim widths.
The T4000F series uses four-cylinder turbodiesels: 3.2-L engines on the T4030 and T4040 and a 4.5-L engine on the T4050, all able to run on biodiesel up to B100, provided it meets ASTM standards. All engines meet Tier 3 emissions regulations, have cross-flow cylinder heads, and a torque rise of up to 39%.
Power and maneuverability are most important for the row tractor; low branches and compact spaces force the T4000F series to be long, low, and thin. A width as narrow as 59 in (1499 mm) with 380/70R20 tires is possible. Cab height has been reduced to 85.5 in (2172 mm) by moving the air-conditioning compressor under the hood, while the optional SuperSteer front axle turns at 76°. This option also includes the front-wheel-drive system, which is electronically managed to engage when needed, reducing fuel consumption and increasing control.
Common applications include spraying and tilling, all managed via 62 to 82 PTO hp (46 to 61 kW). There are three transmission choices, a 16 x 16 mechanical shuttle, 16 x 16 power shuttle, or 32 x 16 power shuttle, each allowing easy directional changes. The 32 x 16 transmission has a push button giving high and low for each gear as well as seven gears below 1 mph (1.6 km/h). While cabs are optional, they can be equipped with antipollen filters, a cab pressurization motor, and air-conditioning. Cabless models have a fold-down roll bar to allow access to low areas.
A CAN bus electrical system provides easy diagnostics and on-dash display of error codes. The hydraulic system begins with a standard two-pump system, but larger variants are available, and an optional frontal three-point hitch is available on the T4050F model.
