What Is a Kubota BX2350 Front Blade Mount (Pin Specs)
A Kubota BX2350 front-blade mount pin joins the blade or hitch to its mounting points and keeps the parts aligned. There is no one confirmed pin size for every BX2350 setup: the correct part depends on the blade and front hitch. Check their model and part numbers before ordering; guessing by tractor model or hole fit alone is unsafe.
If you found “front blade mount pin” in a manual or parts listing, it is reasonable to wonder which piece it means. Several pins may be used at different joints, and they may look alike while serving different positions. I’ll show you how to identify the right one without relying on a guess.
What the BX2350 front-blade mount pin does
A mount pin is a removable metal fastener that connects parts of the blade mounting system. Depending on the assembly, it may secure a hitch to the tractor or connect the blade to the hitch. Its exact role and shape depend on the equipment fitted.
The pin passes through aligned holes in two or more parts. A retainer, such as a hairpin clip or cotter, helps stop it from sliding back out. The pin carries force through the joint; the retainer holds the pin in place.
Do not assume every visible pin is the same. A blade setup can have multiple pins, and one may be a pivot pin while another secures a mounting link. Use the blade or hitch parts diagram to identify the position before you remove or replace anything.
Key point: The BX2350 model identifies the tractor, but does not identify every blade-mount pin.
Why there is no single verified BX2350 pin size
A pin’s size and part number depend on the front hitch and blade assembly, not just the tractor. Kubota and aftermarket equipment may use different mounting parts, and even parts that appear similar may not be interchangeable. Without the assembly identifiers, giving a diameter or length would be a guess.
This is why searching or ordering for “BX2350 front blade pin” alone can lead to the wrong part. A pin that slips through a hole is not necessarily the correct pin: its length, shoulder, retainer position, and intended strength also matter.
| What you know | What it can tell you | What it cannot confirm |
|---|---|---|
| Tractor model: BX2350 | Which tractor you own | The blade or hitch pin specification |
| Pin location | Which joint needs attention | The correct part number by itself |
| Hole diameter | A measurement to compare with a specification | The pin’s load rating or fit |
| Pin appearance | Possible head and retainer style | Whether it is original or compatible |
| Blade and hitch identifiers | A path to the correct parts diagram | Compatibility unless confirmed for that setup |
Key point: Confirm the blade and hitch before buying. Do not order on the tractor model alone.
How to find the exact pin and part number
The safest route is to match the pin’s position in the correct parts diagram to the equipment’s model and serial information. A parts diagram uses a callout number to point to a specific component; that callout can then be matched to a listed part number.
- Identify the blade. Look for a model or part number on its identification plate, label, or stamped marking.
- Identify the front hitch or mount. Record its model or part number, and any serial number or serial range shown.
- Find the matching parts diagram. Use the diagram for that exact assembly and applicable serial range, not a general BX2350 illustration.
- Locate the pin by position. Trace the callout to the pin at the joint you need. Check the listed part number and any notes about serial ranges.
- Confirm the part number. Ask a Kubota dealer or the implement manufacturer to verify the number and check whether it has been replaced by a newer number.
When I help owners sort out a pin question, the most useful details are the blade model, hitch model, serial information, and a clear photo showing where the pin sits. A photo can help identify the location, but it does not replace the parts diagram or part-number check.
If you cannot find a marking, share the equipment details and photo with a dealer or manufacturer before ordering. Next step: Verify the pin’s diagram callout and part number for your exact assembly.
Which measurements help identify an unknown pin?
Measurements can help compare an unidentified pin with a manufacturer’s specification, but they cannot prove that the pin is the right or strong enough part. Measure with calipers on clean, unworn areas. Do not use a worn pin, rust, burrs, or a bent section as the basis for a replacement size.
| Measurement or feature | What to record | Why it matters |
|---|---|---|
| Pin diameter | Diameter at an unworn section | Helps compare the pin with the specified size |
| Usable grip length | Distance across the joint from the head or shoulder to the retaining feature | Shows how much of the pin spans the connected parts |
| Overall length | End-to-end length | Helps distinguish pins with different head or end styles |
| Head or shoulder | Shape and position | May set how the pin seats in the joint |
| Retainer type and location | For example, cross-hole and cotter, or a hairpin clip | Must match the pin and mount design |
| Mount-hole spacing and alignment | How the connected holes line up | Can reveal wear, damage, or an assembly mismatch |
Grip length is the section of the pin that fits through the joint. Retainer means the clip or other locking part that keeps the pin from working out. Record these details, but use them only to help verify the specified part. Measurements do not establish a pin’s load rating or prove compatibility.
If holes look stretched or no longer line up, do not solve the problem by fitting a larger pin. The hole or mount may need repair. Next step: Compare your measurements with the manufacturer’s specification, not with a guess based on appearance.
How to handle and install a replacement pin safely
A pin may be carrying the blade’s weight or holding parts under pressure. Before handling it, secure the equipment so parts cannot drop or shift. Never rely on hydraulics or a jack alone to support a blade or hitch.
Use this safe sequence:
- Park on firm, level ground. Lower the blade, stop the engine, remove the key, and set the parking brake.
- Relieve implement pressure as directed by the equipment manual.
- Support the blade or hitch mechanically before removing a load-bearing pin.
- Check the pin, mounting holes, and retainer for bending, cracks, deep scoring, corrosion, or wear.
- Install only the specified pin and its correct retainer. Make sure the pin seats fully and the retainer locks in its intended position.
- Before operating, check that the joint moves through its intended range without the pin binding or coming loose.
Do not substitute a bolt, piece of rebar, drift, or unverified pin. Do not operate with a missing or loose retainer, damaged holes, or a blade and hitch whose compatibility has not been confirmed. A pin that is too small, only partly engaged, or poorly retained can shear or come out during blade impact. The blade or hitch could then shift or detach.
Key point: Stop if a pin or hole is damaged. Confirm the correct part and repair the mount before using the blade.
Two common pin-identification situations
These examples show how to approach the problem without treating a measurement or visual match as proof. They are general scenarios, not claims about a specific BX2350 assembly.
Situation 1: The pin is missing, but the blade and hitch are marked. Record both sets of identifiers and find the matching parts diagrams. Locate the pin at the correct joint, then verify its part number and serial range with the parts listing or manufacturer. Do not order based only on the empty hole’s diameter.
Situation 2: The pin is present, but worn or bent. Stop using the blade until the pin and joint are checked. Record measurements from an unworn area if possible, but also check the hole for elongation and the retainer for damage. Use the assembly’s parts diagram to identify the replacement; a measurement from a damaged pin is not a reliable specification.
In either situation, keep pins and retainers labeled by assembly and position. Similar-looking parts can be mixed up during storage. Next step: Match the equipment identifiers to the diagram before installing any replacement.
Inspection, care, and storage
A quick check before use can catch loose retainers or visible damage early. Inspect pins and mounting holes before operating and again after an impact. Replace a pin that is bent, cracked, deeply scored, necked down, or heavily corroded; have elongated holes repaired rather than masking the wear with an oversized pin.
Lubricate only as directed in the blade or hitch manual. Keep retainer holes and locking surfaces clear so the pin and clip can seat fully. After the first short operating interval, recheck the mount, pins, and retainers; then inspect them at intervals recommended by the equipment manual.
Before storage, clean and dry the mount, protect exposed metal from corrosion, and store each pin with its correct retainer. Label pins by the blade or hitch assembly and position to reduce mix-ups.
Key point: A sound pin, a sound hole, and a fully seated retainer all matter. A replacement pin alone will not correct a worn mount.
Frequently asked questions
These answers address the most common BX2350 front-blade pin questions. The exact specification still depends on the blade and hitch identifiers, so use the applicable parts diagram or ask the equipment maker to verify a part number.
What size is the Kubota BX2350 front blade mount pin?
There is no single verified size based on the tractor model alone. The blade and front hitch determine the correct pin.
Can I order a pin by saying it is for a BX2350?
That is not enough to confirm a match. Provide the blade and hitch model or part numbers, serial information, and the pin’s location.
How do I find the pin’s OEM part number?
Use the parts diagram for the exact blade or hitch and serial range. Match the pin’s position to its diagram callout, then verify the listed number with a Kubota dealer or implement maker.
Can I measure the old pin and buy one with the same dimensions?
Measurements can help identify a pin, but they do not confirm compatibility or load rating. A worn or bent pin may also give misleading measurements.
What should I measure if the pin is unidentified?
Record its diameter, usable grip length, overall length, head or shoulder shape, and retainer type and location. Also check the mounting holes for alignment and wear.
Can I use a bolt if the original pin is missing?
Do not substitute a bolt unless the equipment manufacturer specifies that exact replacement. An unverified substitute may not fit or hold the joint as intended.
What if the new pin fits through the hole but seems loose?
Do not operate the blade. Confirm the specified pin and inspect the hole for wear or damage. A loose fit may indicate the wrong part or an elongated hole.
What if the retainer is missing?
Do not use the blade until the correct retainer is installed and locks fully. A pin without secure retention can slide out.
Can a damaged mounting hole be fixed with a larger pin?
Do not use an oversized pin as a workaround. Have the mount assessed and repaired as needed, then install the specified pin.
What information should I send a dealer for help?
Send the blade and hitch model or part numbers, serial numbers or ranges, a clear photo of the pin location, and any part numbers you have found. Measurements can help, but do not replace those identifiers.
To identify the right BX2350 front blade mount pin, start with the blade and hitch, not a guessed dimension. Confirm the pin’s position and part number in the correct parts diagram, then check the pin, hole, and retainer before use.
