John Deere Mini Excavator Models and Service Parts

John Deere compact excavators cover operating weights from roughly 1.7 to 6 metric tons, spanning the 17 P-Tier through the 60 P-Tier. Machines wearing the older G suffix, such as the 26G and 35G, remain common in the field. The suffix identifies the generation, and generation is what decides which parts fit.

Key Points

• Weight range: roughly 1.7 to 6 metric tons across the compact line
• Current naming: P-Tier, covering 17, 26, 30, 35, 50 and 60
• Older naming: G suffix machines such as 26G, 30G, 35G and 50G
• Number meaning: approximate size class, not horsepower
• Wears fastest: undercarriage, hoses at pivot points, attachment pins
• Order against: the machine PIN and the engine serial

What John Deere Mini Excavator Models Are There?

The current line is designated P-Tier, and it runs across six size classes.

• 17 P-Tier: the ultra compact machine, with a variable width undercarriage that retracts to around 39 inches, roughly 19 horsepower, and approximately seven feet of digging depth
• 26 P-Tier: a redesigned cab with heat, air conditioning and Bluetooth radio, suited to concrete and footing work
• 30 P-Tier: a wider stance and more power than the 26
• 35 P-Tier: the size class most often chosen, balancing capability against transportability for general trenching
• 50 P-Tier and 60 P-Tier: the larger compacts, capable of trenching beyond twelve feet and handling heavier lifting

The retracting undercarriage on the smallest machine is the feature that defines its use case. At around 39 inches it passes through standard gates and doorways, which is why it appears on interior demolition and back garden work that larger machines cannot reach.

What Does the G in 26G or 35G Mean?

The G is a generation marker. John Deere ran the compact excavator line under G suffix designations before moving to the P-Tier naming, and both generations are widely in service.

The size number carries across the change. A 35G and a 35 P-Tier occupy the same size class. What differs is everything the generational update touched, which typically includes engine specification for emissions compliance, cab and control layout, and hydraulic and filtration arrangements.

For parts, that means the suffix is not optional information. Ordering a cab or hydraulic component for a 35 without stating whether it is a G or a P-Tier is the most common way to receive the wrong part in this range.

How Do I Tell Which John Deere Mini Excavator I Have?

Read the model decal first. On compact excavators it is generally applied to the side of the upper structure or the boom, and it carries the full designation including the suffix.

Decals fade, get replaced and get painted over during resale, so confirm against the PIN plate. Three checks settle it:

• Model decal on the upper structure or boom, for the number and suffix
• PIN plate on the frame, which is the authority
• Cab features, which distinguish generations where a decal is gone entirely

If both decal and plate are unreadable, the engine serial will still identify the powerplant, which narrows the generation considerably.

Where Is the Serial Number on a John Deere Mini Excavator?

The Product Identification Number plate is generally mounted on the machine frame, commonly on the side of the upper structure or within the operator station. Compact excavators carry several separate numbers worth recording together.

• Machine PIN for structural, cab and hydraulic components
• Engine serial, stamped on the engine block, for filters and engine parts
• Attachment serials on thumbs, breakers and augers, which are separate products

Our guide to finding the serial number and year on your John Deere excavator or skid steer covers plate locations and PIN structure across the excavator range in detail.

What Are the Specs Across the Range?

Four specifications decide whether a machine suits a job: operating weight, dig depth, reach and auxiliary hydraulic flow. The model number approximates the first of these and tells you nothing directly about the others.

Read the figures from John Deere's specification literature for your model and serial range. What holds across the line:

• Operating weight spans roughly 1.7 to 6 metric tons and governs transport requirements
• Dig depth ranges from around seven feet on the smallest machine to beyond twelve on the largest compacts
• Auxiliary hydraulic flow determines which attachments will run correctly and is the first specification to confirm when matching a breaker, auger or tiltrotator
• Undercarriage width, fixed or variable, decides site access

Attachment compatibility is where sizing errors surface. Augers and hammers for drilling and breaking, hydraulic thumbs and buckets for material handling, and tiltrotators offering rotation and tilt for precision grading all have flow and pressure requirements that must match the machine.

What Service Parts Do These Machines Need Most?

Compact excavators work in abrasive ground and put continuous load through the hydraulic system. Based on our catalog data, the recurring parts fall into four groups.

Filters. Hydraulic, engine oil, fuel and air, each on its own schedule. John Deere publishes intervals per model, and machines running hydraulic attachments for extended periods need shorter ones than the published baseline.

Undercarriage components. Rubber tracks, rollers, idlers and sprockets wear as a system. Fitting new tracks over worn rollers shortens the life of the tracks considerably, which makes replacing them together the cheaper decision over a full cycle.

Hydraulic hoses and fittings, particularly at boom and arm pivot points where flexing is constant and abrasion is highest.

Cab glass and wiper components. Front and door glass take damage from material handling and demolition work. A 28" Wiper Blade replacing John Deere TY24971 fits a broad range of cab equipped machines, and a Front Lower Glass replacing John Deere AT214097 is an example of a pane cut to a specific opening rather than shared across the family.

Which Parts Interchange Between John Deere Excavator Models?

Interchange follows shared architecture rather than adjacent model numbers.

Generally shared: filters across machines running the same engine, wiper and lighting components where the cab is common, and seals and fittings on shared hydraulic circuits.

Generally not shared: cab glass, which is cut per opening, undercarriage components specific to track width and machine weight, and anything revised between the G and P-Tier generations.

Attachments are a separate matter entirely. A thumb or breaker is its own product with its own parts listing, and its components cannot be looked up from the excavator PIN. Mirror and visibility hardware such as the Value Mirror Kit replacing John Deere M-245-3000 tends to span a wider range of machines, because mounting arrangements changed less often than cab structure.

How Do I Confirm a Part Fits My Mini Excavator?

Work from part numbers rather than model assumptions, because the generation split makes model level matching unreliable.

1. Read the OEM number off the component being replaced
2. Record the full model including suffix, G or P-Tier, plus the machine PIN
3. Use the engine serial for filters and engine components
4. Use the attachment serial for thumb, breaker or auger parts
5. Cross check the OEM number against the aftermarket listing before ordering

Quality aftermarket parts are built to meet or exceed OEM specifications and are generally the more economical route for filters, glass and wear hardware. Customers are responsible for verifying fitment. Send your model, suffix and PIN to sales@partsonline.com and our team will confirm the match. Consult a certified mechanic for hydraulic system work.

Frequently Asked Questions

Who makes John Deere mini excavators now?

John Deere produces its compact excavator line under its own badge, and parts are ordered against John Deere part numbers and the machine PIN regardless of where a given machine was built.

What are common problems with compact excavators?

Across the class, the recurring issues are undercarriage wear, hydraulic hose abrasion at boom and arm pivot points, and attachment pin and bushing wear. Most are maintenance items rather than defects, and inspection intervals catch them early.

How much does a John Deere mini excavator cost?

New and used pricing varies by size class, generation, hours and configuration, so a current dealer quote is the only reliable figure. Undercarriage condition is the single largest variable in used machine value.

Who makes the best mini excavators?

Several manufacturers build capable machines in this class and the right choice depends on dealer support, attachment requirements and site access. Condition and maintenance history matter more than badge when buying used.

What John Deere mini excavator models are there?

The current P-Tier line covers the 17, 26, 30, 35, 50 and 60. Earlier machines carry a G suffix, such as the 26G, 30G, 35G and 50G, in the same size classes.

What is the smallest John Deere mini excavator?

The 17 P-Tier is the smallest, with a variable width undercarriage that retracts to around 39 inches for gated access, roughly 19 horsepower and approximately seven feet of digging depth.

How deep can a John Deere mini excavator dig?

Digging depth ranges from around seven feet on the smallest machine to beyond twelve feet on the 50 and 60 size classes. Confirm the figure for your specific model and boom configuration from John Deere's specification literature.

Do G-series and P-Tier parts interchange?

Some do and many do not. Generational updates changed engine specification, cab layout and hydraulic arrangements, so verify against the OEM part number rather than assuming the shared size number means shared parts.
