Custom Mower with a 2JZ Inline-Six Grind Hard Plumbing is building their ultimate race lawn mower. The team started with a Simplicity 9020 Power Max tractor and promptly started cutting it apart. They welded the pieces together around a Jaguar XJS front and rear subframes. That means the mower will have fully independent suspension and disc brakes. Power will be generated by a 3.0 L 2JZ inline-six mated to a five-speed manual transmission from a Toyota 2WD truck.
