Deere-Powered Pickup Works Like A Tractor
"It makes a great self-propelled spray rig that works like a tractor yet rides like a car," says Paul Gerber, Gadshill, Ontario, about the 1986 Chevrolet 1-ton, 4-WD pickup that he repowered with a 200 hp turbocharged Deere diesel engine.
Gerber, who runs a custom spraying business, uses the 4-WD pickup with a 50-ft. sprayer and 500-gal. tank. His father and brother also use the pickup to haul straw, pulling 30-ft. long wagons loaded with 40 big square bales that weigh a total of 9 tons.
The 359 cu. in., 6-cyl. diesel engine came out of a Deere industrial loader that had been rebuilt. Gerber paid $2,600 for the engine which had a broken crankshaft.
"The pickup's original 292 cu. in. gas engine was underpowered, especially on hills and soft ground. This industrial-type engine is heavier built and much more reliable than the diesel engines found in new pickups," says Gerber. "My neighbor Doug Roth helped me. The extra power combined with the weight of the sprayer make an ideal match. I mounted a big 4-in. dia. chrome muffler off a semi tractor behind the cab so the pickup is also very quiet. It's a pleasure to drive."
He bolted a 4-speed Allison automatic transmission out of an old school bus to the new engine. The turbocharger wouldn't fit under the hood, and he didn't want to make a "bubble" in the hood for it, so he raised the cab 10 in. by making new cab mounts out of square tubing. "The extra cab height really improved visibility in all directions," notes Gerber. He had a big new radiator custom built for the diesel engine. The radiator, grille, and bumper had to be moved forward and up 4 in. He also had to add extra leaf springs on front to handle the extra weight of the bigger engine.
Along with the 4-speed automatic transmission Gerber installed an independent transfer case (off a 205 Dodge) that has a 13-in. long driveshaft. To install it he had to shorten the rear driveshaft and lengthen the front driveshaft. He installed the automatic transmission's gear shifter inside the pickup next to the steering wheel. Custom made exhaust tubing runs from the engine back to the muffler. A 4-in. dia. air cleaner - which came off a Deere 7700 combine - mounts behind the cab and is connected to the air filter under the hood.
"It looks sharp and has unbelievable power, says Gerber. "I could've sold it many times. I spray a few thousand acres every year, using dual wheels for general field work and single wheels for row crop work. Top speed on the highway is about 40 mph.
"I didn't want to use a diesel engine designed for commercial pickups because in my opinion those engines aren't built for field work. They lack reliability because of all the electronic stuff on them. They work great on the highway but not in the field.
"My total cost was about $6,000, including the cost of repairing the crankshaft. It saves money because I can run the pickup hard all day long on an 18-gal. tankful of fuel whereas the gas engine needed about three tankfuls per day.
"The diesel engine starts easier in cold weather than any gas engine I've had, and I don't know why. Last winter it started right up even in temperatures as cold as 10 or 15 below. It also runs quieter than commercial diesel pickups because of the modified exhaust system. It runs so quiet that some people don't even think it's a diesel engine until they look under the hood. The radiator is bigger than necessary but I like knowing the engine will never overheat. A pair of electric cooling fans out of a Chevy Camaro car also help cool the engine. The power steering pump supplies the hydraulic spool valve that's used to fold the boom and to raise and lower it.
"The transmission came out of a gas-powered bus. The rpm's in a gas engine run a lot higher than they do in a diesel engine, so we had to weld weights on the governor to get the transmission to shift properly."
