The Kubota L3700SU Special Utility Tractor is a bit different than the rest of Kubota’s L-series, such as the Kubota L3400 or Kubota L3540 tractors. The main reason for this is the fact that it comes packaged with a Kubota LA463 front loader. This front loader has a maximum dump angle of 40 degrees. It has a maximum safe lift capacity of 518 kg (1142 lbs). The total pump capacity of the hydraulic system of the L 3700 SU is 40. 2 liters per minute (10. 6 gallons/min). This hydraulic system provides the category 1 3-point hitch located at the rear of the tractor with a maximum safe lift capacity of 906 kg.
The engine that drives the hydraulic system of the Kubota L3700SU tractor is a 3-cylinder diesel with a displacement of 1, 826 liters. The 4-stroke engine is kept cool with a liquid cooling system and is vertically aligned. The engine is started by a 12-volt battery that supplies the engine with 490 cold cranking amps. The engine is fed with diesel from a fuel tank with a capacity of 34 liters. The engine drives the wheels transferring power through an HST hydrostatic transmission giving the L3700 SU infinite speeds in 3 ranges (Hi, Medium and Lo). This gearbox gives this special utility a top speed of 22. 7 km/h forwards, while in reverse it reaches a top speed of 20. 5 km/h. It’s almost as fast in reverse as it is in forward.
The Kubota L3700SU Special Utility Tractor comes with a folding roll bar (ROPS). The total weight of the machine is 1165 kg. The L 3700SU tractor has different ballast options, including weights that can be attached to the front bumper and weights that can be attached to the rear wheels. A 74-inch dual-stage snow blower can be attached to the 3-point hitch at the rear of the tractor.
