Overview

The Kubota L5030 is a versatile compact utility tractor, part of Kubota's L30 series, manufactured between 2003 and 2007. It is powered by a reliable four-cylinder Kubota V2403 diesel engine with a displacement of 148.5 cubic inches, delivering a power output of 50 hp. Available with multiple transmission options including hydrostatic, Glide Shift (GST), and a fully synchronized system with creep, the L5030 offers a range of speeds suitable for varying tasks. The tractor features hydrostatic power steering, wet disc brakes, and a choice of operator stations between a two-post ROPS or an optionally enclosed Grand Cab. Supporting a three-point hitch system of category II/I with a lift capacity of 3,860 lbs, this tractor is equipped to handle a variety of implements. Additional details such as total hydraulic flow, PTO speeds, operating weights, and dimensions contribute to the model's adaptability for farm and utility work.
