Keeping the old Cat running

On his ranch near Turtle Lake, Wilfred Hamm is still using his 820 John Deere and D4 Caterpillar

Published: March 16, 2015

The Hamm family originally used this D4 Cat in their sawmill,  and  they  still  use  it  to  put  up  wood  to  heat  their  shops,  as  well  as  one home.

Wilfred Hamm has a large collection of old and antique farm machinery, and much of it is still used on his ranch near Turtle Lake, Saskatchewan.

Wilfred uses an 820 John Deere for cultivating summer fallow. The 820 John Deere is a two-cylinder diesel. It has a four-cylinder pony engine which runs on gas. Wilfred says the John Deere always starts, and requires little maintenance, other than oil changes. Wilfred and his son, Paul, both weld, and can tackle many repair jobs on their own.

But the John Deere’s six-volt generator doesn’t work anymore, and Wilfred can’t source another one. This means that after a week or so of work he has to recharge the battery.

The old JD isn’t the most comfortable ride — in fact, Wilfred’s the only one who uses it regularly. It’s quite loud, so he has to wear hearing protection. But it does have power steering, and Wilfred says he can run it for half the cost of his newer tractor, which has front-wheel assist and an air-conditioned cab.

The little cat

Wilfred Hamm says he originally bought the Cat to skid logs. Wilfred and his family used to run a sawmill, and they still mill their own lumber for corrals and farm buildings. They also use the Cat to bring in wood to heat one house and two shops on the ranch. The dozer blade comes in handy when clearing snow or brush.

The D4 Cat pre-dates hydraulics, and so a cable winch lifts the dozer. Breaking cables aren’t a problem, Wilfred says, as they replace the cables once they start to fray.

The engine is a four-cylinder diesel. It has an electric start pony engine, which runs on gas. The D4 was bought second-hand several years ago, but Wilfred says the only issue he’s had was a leaky radiator, which he replaced.
