Hello Mich, Nath, Norm and Max
The 3210 [pronounced as thirty-two ten] was an extremely popular
mower in the day. It was the choice for many contractors.

It was Theo Reinhold [AKA Mr Greenfield] that designed the
Posi-Traction drive, a simple but robust system, when he was
at Rover Mowers.

It was an enduring design too - with the chassis being updated to
a high-arch with plastic side catcher. This was the 321 chassis.

Cheers
