Who This Fits
The MT573 is a working tractor for farms and heavy chores: hay ground, big loader work, PTO implements that punish smaller machines. If you're feeding cattle or maintaining serious acreage, this is the class built for it. It's also the class the owner runs on his own farm.
Common Questions
What transmission does the MT573 come with?
The MT573 runs a Synchro Shuttle, F20 x R20. Direction changes happen on a shuttle lever, no clutch-pedal dance during loader work. At this horsepower it's the setup most buyers want for steady fieldwork.
Is a front loader available for the MT573?
Yes — LS offers a factory-matched front-end loader for the MT573. You'll find the exact loader model and its published specs in the Factory Attachments section above. Ask us for the current loader package and pricing when you request a quote.
What warranty comes with a new MT573?
New LS tractors carry LS's factory warranty, with powertrain coverage that runs longer than the base warranty. Exact terms can change by model year and promotion, so we'll confirm the current coverage when we quote your unit.
