All-Weather Cab Protection for John Deere 3R Tractors

Bad weather can turn a short tractor job into a long task. However, Cab 40441 helps shield the operator from direct wind and wet weather. The enclosure adds useful cover for work in fall, winter, and spring.

A molded ABS plastic roof forms the top of the cab. Therefore, rain, sleet, and falling snow stay off the main seat area. Its hard surface also gives the enclosure a firm shape.

Cold wind can make snow work feel harsh. Yet the full enclosure helps reduce the flow of air around the operator. You can plow a drive, move feed, or haul firewood with more cover.

This cab fits the John Deere 3033R, 3039R, and 3046R. Still, it is only for 2018 and newer open-station tractors with the correct ROPS. Confirm the model and year before you order.

Safety-Glass Windshield and Electric Wiper

The front windshield uses safety glass for a clear view. In addition, an electric windshield wiper comes with the cab. The wiper helps clear light rain, wet snow, and other moisture from the front glass.

A forward tilt gives the windshield a useful angle. Thus, the glass can have less direct contact with falling rain and snow. Its shape can also help reduce glare during outdoor work.

Clear Lexan plastic forms the side doors and rear curtain. As a result, the operator can see the work area from inside the cab. The shatter-resistant panels can also handle cold weather without the brittle feel of common plastic.

A clear view still depends on good care. Therefore, clean the Lexan with mild soap, water, and a soft cloth. Do not use rough pads, dry paper towels, or harsh glass cleaner on the plastic panels.

Hinged Doors Support Quick Entry

Hinged side doors make it easy to reach the tractor seat. Moreover, door latches help keep each side closed during normal use. The wide clear panels also help you check the area beside the tractor.

Open and close both doors before each job. Next, make sure no tool, coat, wire, or loose item blocks the exit. Stop work if a door or latch does not move as it should.

Keep snow, ice, and mud off the tractor steps. Likewise, face the tractor and use safe handholds when you climb in or out. Never use a clear panel or cab frame as a grab bar unless the guide marks it for that use.

No-Drill Mounting System

Cab 40441 uses holes that already exist on the tractor. Therefore, no drilling is needed for the listed fit. The model-fit mounts help make installation clear and direct.

Most first installs take about three to four hours. Still, tool choice, skill, and tractor setup can change the time. A second adult can help hold the roof, windshield, and frame parts.

Read the full guide before work begins. Then, park the tractor on firm and level ground. Set the brake, turn off the engine, remove the key, and let hot parts cool.

The tractor ROPS must stay in its raised position with this cab. Thus, never fold, remove, cut, drill, or change the ROPS to make the enclosure fit. Follow each mount step in the supplied guide.

Review our tractor cab installation manuals before your cab arrives. If you need help with model fit, please contact Original Tractor Cab before placing an order.

Hardtop Cab 40441 Product Specifications

Measure the Finished Tractor Height

The listed ground-to-roof height is about 85.25 inches. However, tire type, tire pressure, tread wear, and tractor setup can change the final height. Measure your tractor after the cab is in place.

Low doors, limbs, pipes, and beams can strike the roof. So, leave more room than the measured height when you pass below an object. Never guess at overhead space from the seat.

Confirm Model Year and Cab Fit

First, find the tractor model and product tag. Next, confirm that your unit is a 2018 or newer 3033R, 3039R, or 3046R. An older tractor may use a different frame or mounting layout.

This enclosure is for an open-station tractor. By contrast, it does not replace or attach over a factory ComfortGard cab. Added lights, mirrors, controls, exhaust parts, or tools may also affect fit.

For other model-fit options, shop our John Deere tractor cab collection. You can also view tractor cab accessories for lights and other useful add-ons.

John Deere 3033R, 3039R and 3046R Specifications

John Deere 3R tractors pair a small frame with strong tool power. As a result, they suit land care, farm chores, loader work, mowing, and snow removal. Each model offers a different level of engine power.

All three tractors use a three-cylinder Yanmar diesel engine. However, their engine systems and power ratings are not the same. Buyers should match the model to the load and type of work.

The 3033R supplies about 32.2 gross horsepower. Meanwhile, the 3039R raises gross power to 38.2 horsepower. The 3046R provides about 44.7 gross horsepower.

For current factory details, visit the official John Deere 3 Series tractor page. You can also review the maker’s John Deere 3039R product page.

3R Series Engine Comparison

Specifications can change with the model year and market. Therefore, use the tractor serial tag and operator manual as the last word for your machine. Never use general web data to set a safe load limit.

Yanmar Diesel Power

The 3R line uses Yanmar diesel power for strong low-speed work. In addition, direct fuel injection helps support clean and firm starts. A high torque reserve helps the engine work through changing loads.

The 3039R uses a turbocharged engine. Meanwhile, the 3046R adds an intercooler to its turbo setup. These systems help the larger models make more power from a compact engine.

Final Tier 4 controls help the engines meet current exhaust rules. Thus, some models use a diesel oxidation unit and a diesel particle filter. Follow the tractor manual for filter cleaning and exhaust care.

Transmission and Twin Touch Controls

John Deere offers an electronic hydrostatic drive on the 3R line. Therefore, Twin Touch foot pedals let the operator control forward and reverse travel. No clutch is needed for normal direction changes.

Three drive ranges help match speed to the job. For example, a low range suits hard pulling or slow loader work. A higher range works well for travel across open land.

Cruise control helps hold a set travel speed. Likewise, the eThrottle feature can link engine speed with pedal movement on equipped tractors. These tools can make long mowing jobs feel more simple.

Available transmission choices can vary by model. So, check the build sheet for your exact tractor. The operator manual will show the right use for each control.

Three-Point Hitch and PTO Use

A rear three-point hitch lets the 3R Series use many land care tools. As a result, owners can run a tiller, blade, box scraper, cutter, or other approved tool. The rear PTO supplies power at 540 rpm.

Some tractor setups also support a mid PTO. Thus, owners may use a compatible mower deck or front tool. Cab parts must never block a PTO control or safe exit.

Always match tool weight and power needs to the tractor model. Moreover, use the right ballast for loader or rear-tool work. Follow the Deere manual when you add or remove ballast.

Loader and Property Care Work

The 3R tractors can handle many jobs on a home site or small farm. For instance, a loader can move mulch, soil, gravel, snow, and feed. Rear tools can grade paths or prepare garden soil.

Cab 40441 can add value during this work. In fact, the enclosure helps keep direct wind and wet weather away from the operator. Clear side panels support a wide view of the nearby job site.

Never raise a loader higher than needed while moving. Instead, keep the load low and travel at a safe speed. Avoid steep slopes and sudden turns with material in the bucket.

Snow Removal with Cab 40441

Snow work often puts the operator in cold wind for a long time. However, the hardtop cab adds a covered space around the seat. The front wiper also helps keep wet snow off the safety-glass windshield.

A blade, blower, or loader can help clear a drive. Still, snow can hide curbs, rocks, ice, and holes. Mark the work area before the first storm when you can.

This enclosure does not include a heater. Therefore, dress for the air temperature and expected work time. Watch for cold stress during long jobs.

ROPS and Seat-Belt Safety

The tractor ROPS must remain raised while Cab 40441 is in use. In addition, use the seat belt as the John Deere manual directs. The cab fabric, roof, and frame do not provide certified rollover protection.

Do not change the ROPS or its mount points. Likewise, never attach a tow rope, chain, or load to the cab frame. Use only the tractor points that Deere approves for towing or pulling.

The History of Original Tractor Cab

Original Tractor Cab began in 1939. At that time, Indiana farmer Stanley Williams needed more cover from harsh weather. So, he made a cab for his own tractor.

Other farmers soon saw the value of his idea. Then, Stanley placed a small ad in a farm magazine. The strong reply showed that many workers shared the same need.

That simple cab led to a new American company. As a result, the team began to make cabs for the leading tractor brands of the day. Real farm work shaped each early design.

During World War II, the firm turned its skills toward the war effort. Its workers made backpacks and other vital goods for military use. Afterward, the company returned its focus to products for outdoor work.

Tractors and outdoor machines changed through the years. Therefore, Original Tractor Cab kept adding new model-fit products. Its range grew to include hardtop cabs, soft enclosures, sunshades, and cab accessories.

The Williams family carried the company forward through three generations. Moreover, each new product kept the same core aim: practical weather cover for people at work. Family skill and shop knowledge still guide the brand.

Original Tractor Cab remains in Arlington, Indiana. In fact, American production has been part of the company since its early years. Cab 40441 carries that long history into a modern tractor fit.

Today, the company serves tractor, mower, and utility equipment owners across the nation. Yet the main goal stays much the same as it was in 1939. Read more on our Original Tractor Cab history page.
