John Deere J3816 Chainsaw (Specs & Price Guide)
The John Deere J3816 is a 38-cc-class chainsaw specified with a 16-inch guide bar, suited to light-to-moderate property work when the saw is sound and correctly equipped. It is a discontinued model, and I can’t verify a current market price. Before buying or cutting, confirm the exact saw, fuel mix, and compatible chain from its label and model-specific manual.
If you are comparing saws for storm cleanup, pruning, or firewood, the right choice depends on your trees, workload, and the saw’s condition. A 16-inch bar does not mean every 16-inch tree is a safe cut. Wood species, trunk shape, lean, defects, and your skill all matter.
Local needs vary, too. A small suburban lot may call for occasional limb cleanup, while a rural property may need regular firewood cutting. In either case, a used saw’s history and serviceability matter more than its old retail price or a seller’s claim that it is “powerful for its size.” I would treat this model as a used-equipment purchase that needs careful checks, not as a bargain based on the name alone.
J3816 specifications: what is known and what needs checking
These are the model-identification details I can support: the J3816 is in the 38-cc class and is specified with a 16-inch guide bar. Other setup details must be checked on the individual saw or in documentation for its exact version; a model name alone is not enough to choose parts or settings.
| Item | What to know | What to verify |
|---|---|---|
| Engine class | 38 cc | Confirm the model label on the saw |
| Guide-bar length | 16 inches | Check the installed bar stamp and condition |
| Chain pitch and gauge | Not established by the model name alone | Match the bar stamp and replacement-chain listing |
| Drive links | Not established by the model name alone | Count or confirm against the bar and chain listing |
| Fuel ratio | Do not assume a ratio | Check the manual for the exact version |
| RPM, oil flow, and adjustment values | No model-specific values verified here | Use the correct service documentation |
“Pitch” is the spacing between chain drive links, while “gauge” is the thickness of the drive links that fit into the bar groove. “Drive links” are the parts of the chain that sit in that groove. All three must match the bar. Do not order a chain by bar length alone.
A guide bar is the metal track that supports the chain. Its length is not a safe tree-size rating. If the installed bar does not appear to be the specified 16-inch size, or its stamp is unreadable, resolve compatibility before use.
Price guide: how to value a used J3816
There is no live-market price verified for this discontinued saw, so I would not give a dollar figure that implies a current market value. A fair offer should reflect the saw’s working condition, serviceability, included bar and chain, and any faults. The original retail price, if a seller cites one, does not establish what a used unit is worth today.
I assess a used saw in this order: identity, safe function, engine operation, cutting parts, and repair risk. A clean exterior is not proof of a healthy engine, and a running engine is not proof that the chain brake or oiling system works.
| Condition at inspection | Buyer’s approach |
|---|---|
| Starts cold and hot; controls, brake, and lubrication work; no clear damage | Compare its condition and included parts with other available saws |
| Runs but has an untested brake, poor oiling, leaks, or damaged parts | Do not treat it as ready to cut; identify repair needs first |
| Will not start or cannot be tested | Value it as a parts or project saw, not as a working saw |
| Model label or bar/chain details cannot be confirmed | Pause until identity and compatibility are established |
Before paying, ask to see a cold start and a restart after the saw has warmed. Test the chain brake and confirm chain lubrication using the manual’s procedure. Look for fuel or oil leaks, cracks, damaged handles, loose fasteners, worn bar rails, and a chain in poor condition. If the seller will not allow basic checks, account for that added uncertainty rather than assuming the saw is sound.
I would not estimate a repair cost without a diagnosis and parts information for the exact version. If the seller describes a fault as “just a carburetor adjustment,” ask for a running demonstration or a mechanic’s assessment. Treat an unverified claim as a risk, not a confirmed repair.
Buying and compatibility checks
A compatibility check means confirming that the saw, bar, and chain fit and function together. For this model, the bar stamp and the exact-version operator’s manual are more useful than a generic online listing. If either is missing, get authoritative model-specific documentation before buying parts or fueling the saw.
Check the exact saw and cutting parts
Read the model label rather than relying only on a seller’s description. Check the guide-bar stamp for the chain details, then confirm the replacement chain listing matches pitch, gauge, and drive-link count. Do not guess these values from “16 inch.”
Inspect the bar rails for damage and uneven wear. Check that the chain is not cracked, badly worn, or incorrectly fitted. A sharp chain matters, but do not use sharpening as a substitute for correcting a mismatch or damaged part.
Confirm fuel and oil requirements
The correct fuel-oil ratio for the J3816 is not established here. Do not assume 50:1 or use straight gasoline. Find the instruction manual for the exact version and use its stated ratio and specified two-stroke oil. If you cannot confirm the requirement, do not fuel or start the saw until you have reliable documentation.
Bar oil goes into a separate reservoir from fuel. Use the manual to identify the correct oil and how to check flow. Do not rely on a guessed viscosity or flow rate, since no model-specific value is verified here.
Equipment setup and safety preparation
Preparation means checking the saw, protective gear, and work area before starting. It reduces avoidable risk but cannot make a poor cut or defective saw safe. Wear a helmet with face and eye protection, hearing protection, chainsaw chaps, gloves, and protective footwear before handling a running saw.
With the engine off, inspect the chain brake, throttle lockout, chain catcher, handles, fasteners, chain tension, bar rails, and chain condition. If the brake is defective or its function is uncertain, do not use the saw. Check the manual for the correct tension procedure; retension only with the engine off and chain cool.
Clear bystanders and obstacles from the work area. Plan a retreat path and consider the tree’s lean, overhead hazards, wind, and likely fall direction before any felling work. If the site or tree is beyond your training, do not attempt the cut.
Field cutting and landscaping operation
Operation means starting and cutting in a way that keeps the saw under control. The model’s 38-cc class and 16-inch bar do not establish that a particular tree is safe to fell. Tree condition, wood diameter, species, lean, and operator skill all affect the risk.
Start and check lubrication
Use fresh fuel mixed at the ratio specified in the J3816 manual, and fill the bar-oil reservoir separately. Start the saw on stable ground and follow the manual’s cold- or warm-start steps. Engage the chain brake for starting if the manual directs it.
Before cutting, confirm that the chain is receiving oil using the manual’s check. If oiling is not working or you cannot confirm it, stop and diagnose the issue before cutting. Poor lubrication can damage the cutting system.
Cut with the bar nose clear
Hold the saw with both hands and keep a stable stance. Do not cut above shoulder height or force a dull chain through wood. Keep the upper tip area of the bar away from wood and other objects: contact there can cause rotational kickback, driving the bar rapidly up and toward you.
Do not attempt tip-boring or complex cuts unless trained and properly equipped. Felling trees also requires a sound plan for the drop zone and escape route. If you lack the training or cannot assess the site, leave the work to a qualified person.
Maintenance, sharpening, and seasonal care
Maintenance means following model-specific instructions to keep the saw’s cutting parts, engine, and safety features in working order. No verified J3816-specific adjustment values are provided here for idle speed, maximum engine speed, depth gauges, oil flow, or fastener torque. Use the correct service manual and chain maker’s instructions instead of generic numbers.
After use, engage the brake, shut off the saw, and let it cool before cleaning. Remove debris and inspect the chain, bar, air filter, and oiling system as directed by the manual. Check for damage before the next use.
Keep the chain sharp and set its depth gauges, also called rakers, to the chain manufacturer’s specification. These control how deeply each cutter bites. Do not guess the clearance. Use the specified file, gauge, and method, or have a qualified service shop do the work.
Follow the manual for bar-nut tightening and other fasteners. Do not substitute guessed torque values or overtighten. For storage and transport, use the manual’s instructions, including any direction on fuel handling and protecting the bar and chain.
Practical purchase scenarios
These are decision examples, not claims about specific J3816 owners or actual sales. They show how I would apply the verified specifications and inspection checks to common buyer situations.
| Buyer situation | What the J3816 may fit | Decision point |
|---|---|---|
| Occasional limb cleanup on a small property | Light work may suit a sound, correctly equipped saw | Confirm the parts, safety features, and fuel instructions |
| Regular firewood cutting | Suitability depends on wood, volume, and operator skill | Compare workload with the saw’s condition and available service |
| Storm-damaged trees or planned felling | The bar length alone cannot establish suitability | Assess hazards and training; use a qualified professional if needed |
| Non-running saw offered at a low price | It may be a project or parts unit | Buy only with repair risk understood, not as a ready-to-work saw |
For a buyer with limited cutting needs, a verified, safe used unit may be worth considering. For heavy or frequent work, do not decide on displacement or bar length alone. Compare the actual workload, the saw’s condition, and the support available for repairs and parts.
Conclusion: should you buy the J3816?
The J3816 is identifiable as a 38-cc-class saw with a specified 16-inch bar, but that does not answer every buying question. Fuel ratio, chain fit, and service settings require exact-version documentation. There is no verified live price here, so condition and repair risk should guide your offer.
Before buying, confirm the model label, inspect the bar stamp, see a cold start and hot restart, test the chain brake and oiling, and look for leaks or damage. If a safety feature is defective or untested, do not cut with the saw. If the unit will not run, value it as a project rather than a working chainsaw.
FAQs
