Get your John Deere 40 Series Tractor Ready for Spring with LED Lights and Cab Interior from Hy-Cap

Updated: Apr 6

John Deere's 30 & 40 Series tractors are getting older, but there is a reason they have been a mainstay on many farms since the Eighties. The horsepower range is perfect, not too little yet not too big. They make great smaller planting tractors, are used for pulling wagons, and are also good for mowing ditches and moving snow.

Jerry from JKB Application loves having his John Deere 4640 tractor around. "They are so versatile, you can hook up to anything," he said. If you have one of these tractors, chances are you enjoy it just as much as Jerry. So, why not get the most out of it? With some simple updates, you can get these tractors ready to use just in time for spring!

We teamed up with Jerry to install Hy-Capacity LED lights everywhere we could on his John Deere 4640 tractor. In total, there are 17 lights on the machine!

In addition to the 17 LED lights, Jerry's tractor was also fitted with various Cab Interior products that can fit 30 & 40 Series tractors. These Cab Interior products, along with our ISO Hydraulic Couplers, were installed to make this 40+-year-old tractor more modernized to today's standards.

(2) 8302143 CREE LED PAR36 Flood Beam Bulb

(2) 8302205 CREE LED PAR36 Trapezoid Beam Bulb w/ Original Halogen Style Lens

Jerry wanted to add as much light as he could to his tractor, so he got creative by adding LEDs in areas his tractor didn't typically have lights.

"On the front of the tractor, we added a couple of Spot Beam lights (8301645), which is not applicated to this model. It's hard to get light in front of you. You never have enough light or HP!" - Jerry, JKB Application

As you can see, these lights can be attached near the grill of the tractor to add some extra light. This is a great option if this is a tractor you are using on a consistent basis.

"A Flood Beam light (8301654) was added to the rear cab roof. This helps when hitching up equipment and moving snow." - Jerry, JKB Application

Optional Lights:

(1) 8301654 CREE LED Flood Beam Light (used on Front Grille as shown)

(2) 8301645 CREE LED Spot Beam Light (used on Rear Cab Roof as shown)

Last spring, Jerry installed new Quick Connect Hydraulic Couplers on his 4640. “This is an upgrade you have to do to be efficient. People aren’t using the older style tips that OE had on the tractor now that implements and pulling equipment have been switched over to ISO Couplers.”
