Deere 45 Loader Converted To Double Action Dynamo

After totally rebuilding the Deere 45 loader on his 1954 Deere 60 tractor, Tony Bunniss can do a whole lot more work than he could before.
"I've dug stumps and rocks out. Once, I even used the loader to push the tractor out after getting stuck," says Bunniss. "It's so powerful I only stop loading when the tractor's back end comes off the ground."
To get the extra power, he reworked the hydraulic system on the tractor and added a beefed up loader. Extra cylinders replace the old bucket trip.
To get full use from the more powerful loader, he built a new 8-ft. bucket. Pockets at the rear store chains, clevises and other tools. He also built a forklift that's equipped with quick-tach knuckles.
To modify the tractor he installed an open-center control valve under the hood with foot controls for it on the platform. He removed the pressure pipe from the "power trol" and rerouted the oil to the open-center valve.
"I installed a hose from the valve to the power-trol," says Bunniss. "This made it possible to have two separate hydraulic pressures from the same pump. I have the original pressure of 1,200 psi at the power-trol and 2,000 psi for the loader."
He also added an extra tank alongside the rear housing that is coupled to the bottom drain plug. It automatically maintains the same level of fluid that is in the "power-trol" system and adds about 3 gal. capacity.
Because he planned to carry heavier loads, Bunniss decided to install power steering. He used a combination of original Deere 60 parts as well as newer, improved parts from a Deere 620 and a 630.
Loader rebuilding was even more drastic, beginning with new pins and bushings. Machining new pistons and threaded rod ends for the lift cylinders allows him to apply down pressure to the loader. Braces that were on the sides of the rear masts were relocated to the centers of the mast for more support. This eliminated twisting of the masts that he encountered when switching from lift to down pressure.
He beefed up the loader arms by cutting the main tubes behind the bucket mount and machining another pipe to fit inside them. He then spot-welded that pipe by drilling holes in the original pipe.
Two 3-in. cylinders mount on the main arms just behind the front end of the tractor to provide tilt to the bucket and fork lift. It is the extent of tilt on the forklift, actually curling it back, that allows him to use it for stump and rock removal.
"I tried to keep the old loader looking as original as possible, but these loaders weren't Deere's finest hour," says Bunniss.
