What sort of mower are you using Charlie?
Sickle-bar, gang, or rotary slasher?
I only ask because those wee Ford-Ferguson things were terribly under powered, nineteen to twenty-four horses, and absolutely no torque!

(They were essentially Ferguson; built under licence by Ford . . . incidentally,
there's one here in New Zealand that's had a tummy transplant . . . now running a Lincoln Zephyr V12! Quite a wee beast!)
