John Deere GT262 Drive Belt (Routing Diagram)
The GT262 can have more than one belt path, so there is no dependable universal routing diagram based on the tractor model alone. First identify whether you are replacing the tractor’s hydrostatic drive belt or the mower-deck PTO belt. Then match the tractor serial number and, for a deck belt, the deck model to the correct John Deere parts listing or technical manual.
Equipment Setup & Safety Prep
A belt-routing job starts with identifying the belt, not removing it. The GT262’s tractor drive belt and its deck/PTO belt serve different systems and follow different pulley paths. Serial number and deck details matter because a diagram or part number for another setup may not fit yours.
Identify which belt you are replacing
The tractor drive belt transfers engine power to the hydrostatic transmission. The deck/PTO belt transfers power from the PTO clutch to the mower-deck pulleys. These belts are not interchangeable, and a diagram for one system cannot guide installation of the other.
Use this quick distinction before searching for a diagram:
| What you notice | Belt system to identify | What to verify |
|---|---|---|
| Tractor will not move normally, or the drive belt appears loose or damaged | Tractor drive | GT262 serial number and the correct drive-system diagram |
| Mower blades do not engage, or the deck belt is worn or displaced | Deck/PTO | Tractor serial number plus the mower deck’s model or identification details |
| Belt is missing, or the old path is hard to see | Uncertain | Identify the system and consult the matching manual before routing |
Do not choose a belt from appearance alone. Similar-looking belts can differ in fit and application. A belt that seems close may still sit incorrectly in a pulley or fail under load.
Make the tractor safe to inspect
Park on level ground, lower attachments, disengage the PTO, set the parking brake, remove the key, and let the engine cool. Disconnect the battery’s negative cable before working near belt-driven parts. Keep hands and tools clear of pulleys, springs, and belt guides.
Before loosening anything, record the tractor serial number and read the mower-deck identification tag if you are working on the deck. Use those details to find the applicable John Deere parts listing or technical manual. The model name “GT262” by itself does not confirm belt length, belt section, pulley order, or spring orientation.
Take a clear photo of the existing belt path and make a simple sketch. Note which pulleys have V-shaped grooves and which idlers have flat faces. Also record which side of each guide or keeper the belt passes. A photo helps, but it does not replace the correct diagram, especially if the old belt has already slipped out of place.
Field Cutting/Landscaping Operation
A correct routing diagram shows the path for the exact system and setup being serviced. A broad schematic can help you understand the difference between the drive and deck systems, but it cannot provide the GT262’s pulley sequence or belt dimensions. Confirm those details in the serial- and deck-specific information before fitting a belt.
Use the right diagram, not a look-alike
The illustration below is a system distinction, not an installation route:
TRACTOR DRIVE SYSTEM
Engine → drive-belt system → hydrostatic transmission
DECK/PTO SYSTEM
PTO clutch → deck-belt system → mower-deck pulleys
The arrows show only the power flow. They do not show the number or order of pulleys, the side of an idler to use, or the position of a spring. Those details must come from the diagram for your tractor and, for deck work, your installed mower deck.
A useful comparison when you are looking up the correct information is:
| Question | Tractor drive belt | Deck/PTO belt |
|---|---|---|
| What does it power? | Hydrostatic transmission | Mower-deck spindle and idler system |
| Does deck width identify it? | No, not by itself | Deck model or width is needed along with tractor serial number |
| Where should the route come from? | Applicable GT262 technical information | Diagram for the installed deck and tractor fitment |
| Can another GT262’s route be assumed to match? | No | No |
If a parts catalog or manual shows more than one listing, compare the serial number range and deck identification carefully. Do not use a route from a different deck width, model year, or tractor simply because the picture looks similar.
Install and check the replacement belt
Once the correct belt and diagram are confirmed, follow the applicable service instructions for access and belt removal. Avoid forcing a belt over a pulley or changing the position of a spring or keeper to make it fit. If the belt does not sit naturally along the specified path, stop and recheck the part number and route.
Use the diagram to confirm each contact point. A belt generally sits in a pulley’s V-groove or rides on a flat idler as intended by that system’s design. It must also pass on the correct side of each guide. Do not guess the route from the direction the old belt appears to twist.
Before restoring power:
- Check that the belt is seated in every specified groove.
- Confirm that guides, keepers, guards, and springs are back in their correct positions.
- Look for contact with the frame, wiring, or control linkage.
- Remove tools and loose material from the work area.
- Reconnect the battery only after the work area is clear.
Do not run the tractor with required guards or belt keepers removed. With the operator seated and the area clear, start at low idle and test the repaired drive or PTO system as appropriate. Then shut the tractor down, remove the key, and inspect belt seating again. Never reach toward a moving belt.
Maintenance & Sharpening/Tuning
Belt condition and pulley condition need to be checked together. A new belt may fail early if an idler is seized, a pulley is damaged, or the route is wrong. Inspect the related parts while the tractor is shut down and secured, and use the correct service information for any adjustment or repair.
Check for causes of repeat belt failure
Look for cracks, fraying, glazing, oil, grease, and signs of unusual wear. Also inspect pulleys for debris, sharp edges, misalignment, bearing play, or failure to turn freely when the system is safely isolated. Check the condition of idlers, tension springs, guides, the PTO clutch, and guards.
A damaged or contaminated belt should not be treated as a routing problem alone. Clean packed grass and dirt from the area with the tractor shut down and isolated from accidental starting. Keep oil and grease off belt surfaces. If a belt repeatedly comes off or wears in one area, find the cause before installing another one.
| Finding | What it may point to | Safe next step |
|---|---|---|
| Belt is glazed or cracked | Wear, heat, or age | Replace only after confirming fitment and route |
| Belt is frayed at one edge | Misalignment, rubbing, or incorrect routing | Inspect guides, pulleys, and clearance |
| Belt smells burnt, smokes, or squeals | Slippage, binding, or another fault | Stop immediately; inspect only after shutdown |
| Belt walks off a pulley | Incorrect route, damaged parts, or poor alignment | Do not keep testing; confirm the diagram and inspect components |
| New belt fails again | The underlying cause may remain | Check pulleys, idlers, springs, guides, and belt fit |
Do not infer a belt’s size or part number from a removed belt that may have stretched or been installed incorrectly. Confirm the replacement against the serial-specific listing and installed deck details. A visually similar belt is not proof of correct fit.
Storage & Seasonal Care
A short inspection before storage and again before seasonal use can reveal damage before the tractor is needed. Keep the belt area dry and free of oil, grease, and packed grass. Check the belt, pulleys, guides, guards, and spring condition with the machine safely shut down.
Before putting the tractor away
Clean debris from the belt area without reaching into moving parts. Look for cracks, frayed edges, glazing, and signs of rubbing. If you remove a belt for service, keep the correct routing information with your maintenance notes so the route is easy to confirm later.
Before the first use of the season, verify that the belt remains on its intended path and that all guards and keepers are installed. If you see a displaced belt, a damaged guard, or a loose part, do not start the tractor until the issue is corrected.
Stop using the machine if a belt walks off, smokes, squeals, or vibrates. A misrouted or damaged belt can contact a keeper or frame, fail under load, or expose the operator to moving parts or thrown debris. Shut down, remove the key, and investigate only after all motion has stopped.
Field Scenarios: Choosing the Correct Route
These examples describe common troubleshooting situations, not confirmed GT262 repair records. They show how to narrow the question without guessing at a pulley sequence. In each case, the next step is to identify the belt system, confirm the machine details, and use the matching diagram.
The tractor moves poorly after belt work
If the complaint concerns tractor movement, first establish whether the affected belt is the hydrostatic drive belt. Record the tractor serial number and consult the applicable drive-system information. Do not use a mower-deck belt diagram to route a transmission drive belt.
If the belt is already displaced, avoid restarting the tractor to see whether it will settle into place. Inspect the belt path, guides, and pulleys with the tractor shut down. If the route cannot be confirmed, pause and obtain the correct manual or parts information.
The blades will not engage after deck service
If the tractor drives but the blades do not engage, identify the deck model from its tag and pair that information with the tractor serial number. Find the deck-specific belt listing and routing diagram. A deck that looks similar may use a different belt path, so do not rely on a picture from another machine.
After installation, check that the belt is seated correctly and that the deck guards and keepers are restored. Test the PTO only from the operator’s position, with the area clear and all required guards installed. Shut down before checking belt seating again.
The replacement belt does not seem to fit
Stop rather than stretching, twisting, or forcing it onto a pulley. Recheck whether you ordered a drive belt or a deck/PTO belt, then verify the serial number and deck identification used for lookup. A mismatch in system or deck details can lead to the wrong belt even when the tractor model is correct.
Conclusion
There is no reliable one-size-fits-all GT262 routing diagram. The correct path depends on whether you are servicing the hydrostatic drive belt or the deck/PTO belt, and deck-belt fitment also depends on the installed mower deck. Confirm the tractor serial number, deck identification, and applicable John Deere diagram before installation.
Photograph the old route when it is intact, inspect the related pulleys and guides, and restore every keeper and guard. If the belt smokes, squeals, vibrates, or walks off, stop and correct the cause before using the tractor again.
FAQ
These answers address the main fitment and routing questions for GT262 belt service. The key rule is to identify the belt system and confirm the machine details before ordering or installing parts. Where exact dimensions or pulley order are needed, use the serial- and deck-specific John Deere information rather than a generic image.
Is there one routing diagram for every GT262?
No. Drive-belt and deck/PTO-belt routes are different, and deck routing depends on the installed mower deck. Confirm the tractor serial number and deck identification before using a diagram.
How do I tell which GT262 belt I need?
Identify whether the problem is with tractor movement or mower-blade operation. The first points to the drive system; the second points to the deck/PTO system. Confirm the correct part using the applicable serial-specific information.
Does the GT262 model name confirm the belt size?
No. Do not infer belt length, section, or part number from “GT262” alone. Use the tractor serial number and, for deck belts, the deck identification.
Can I use a routing picture from another GT262?
Not safely without confirming that the tractor serial range and installed deck match. A similar-looking tractor or deck may have a different belt application or route.
What should I photograph before removing the belt?
Photograph the full belt path, pulley contact points, guides, keepers, and spring positions. Note which pulleys are grooved and which are flat. Use the correct service diagram to verify the route.
What if the old belt has already come off?
Do not guess from memory or restart the tractor to watch the belt move. Identify the belt system and use the matching technical manual or parts information before installation.
What does it mean if a belt keeps coming off?
Possible causes include incorrect routing, poor alignment, worn or damaged pulleys, a faulty idler or spring, or a belt that does not fit. Stop repeated testing and inspect the system with the tractor shut down.
Can I test the belt with the guards removed?
No. Do not run the tractor with required guards or belt keepers removed. Keep hands and tools away from moving belts, and inspect belt seating only after shutdown.
What should I do if the belt squeals or smokes?
Stop the tractor immediately, remove the key, and let all parts stop. Inspect for misrouting, slippage, binding, or damage before operating again. Do not reach toward a moving belt.
Should I replace a belt that looks cracked or frayed?
A cracked, frayed, glazed, or oil-soaked belt should be treated as damaged. Confirm the correct replacement and check pulleys, guides, and alignment so the cause of wear is not left in place.
