What is an RTV

Some people get confused between different makes and models of what are commonly referred to as utv’s and rtv’s. There are basically two types of vehicle, an atv and a utv. Kubota make their own utv which they refer to as an rtv.

Different types of RTV parts

Aftermarket – New parts made by an alternative manufacturer which are normally almost identical to manufcaturers parts, but often considerably cheaper.

Manufacturer parts – Specific parts made by Kubota, often referred to as OEM Parts, often normally required to be fitted to comply with terms of any warranty in place.

Salvage Parts – used parts that are normally taken from a used rtv that either no longer works, or has run its lifetime, but certain parts are still useable.
