It's interesting it is V'd both sides.
I've got a Stihl/Viking 42" ride-on sitting here with a dead motor and it's deck is really simple. I'd take it any day over a modern John Deere/Sabre mower. The only issue I've had with it when I was doing heavy duty mowing and landscaping work was the wheel slip as it didn't have a locking diff.
The Tecumseh/Peerless 6 speed hydro transmission has handled towing a loaded 300kg trailer up rocky slopes and carting 50kg+ bluestone blocks on a custom built bolt on carrier.
By the way, the chassis is still in good condition without any cracks after having weights on the front and frequently driving on only the rear wheels when carting the bluestone.
The only reason I stopped using it was when the Briggs was blowing all the oil out the breather ever 15 minutes. (This motor had significant blow-by since new by the way with no assistance from the dealer)
Then I bought a second hand Greenfield to use for the heavy duty mowing & hired with the intent to purchase a Vermeer mini skid steer for the landscaping work until the customer lost all their money in the collapse of the Banksia Financial Group.
