John Deere 3033R Troubleshooting
The
John Deere 3033R compact tractor was manufactured from 2014 to 2021. The John
Deere 3033R tractor is powered by 100.2 cu.in (1.6L) Yanmar 3TNV88 4-cycle
3-cylinder direct injection liquid-cooled diesel engine with a max output power
of 33 hp (24.6 kW).
The John Deere 3033R is fitted with two transmission options:
PowrReverser power shuttle transmission with 12 forward and 12 reverse
gears, or three-range hydrostatic transmission with infinite forward and
reverse gears. The maximum travel speed (forward and reverse): 19.1 mph
(30.6 km/h) / 18.5 mph (29.8 km/h).
The open center hydraulic system used a gear pump with a rated capacity
of 8.6 gal/min (32.7 l/min). The hydraulic system pressure is 172 bar
(2500 psi). The tractor is equipped with a hydrostatic power steering,
wet disc brakes, 7.00x14 (AG) or 27x8.50-15 (Turf) front tires, and
11.2x24 (AG) or 41x14.00-20 (Turf) rear tires. The wheel base is 68"
(1720 mm).
The John Deere 3033R is compatible with the following attachments: 60"
or 72" mid-mount 3-blade mower decks with cutting height of 1.5-6.0"
(38-127 mm) and hydraulic lifting, John Deere H160 front-end loader with
lift capacity to full height of 1360 lbs (616 kg),
