For a John Deere D105, begin with the tractor serial number and the engine fitted to the machine. Deere’s historical service-kit table separates two serial branches, so the model badge alone is not enough to select a kit.
D105 Serial and Engine Reference
John Deere’s , updated November 21, 2019, records these D105 branches:
| Tractor serial | Engine stated in the row | Historical kit |
|---|---|---|
| Through 200000 | 31G777-0306-G5 (MIA12433) | LG266 |
| 200001 onward | Not stated for this branch | LG271 |
Use the tractor serial to choose the branch, then read the installed-engine marking. The engine identified in the early row must not be assumed for the later branch. Confirm the current service-parts reference for the identified engine before ordering. If the engine has been replaced or its marking cannot be identified, confirm its identity first.
Equipment & supplies
D105 Maintenance Kits by Serial Branch
Match the serial branch above, then confirm the installed engine and applicable market in the current parts reference. A D105 model name alone does not establish fit.
John Deere LG266 maintenance kit
Deere's November 2019 D105 table lists LG266 through serial 200000, with engine 31G777-0306-G5 (MIA12433). Check the engine actually fitted before ordering.
John Deere LG271 maintenance kit
Deere's November 2019 D105 table lists LG271 from serial 200001 without naming the engine for that branch. Confirm the installed-engine application; do not carry over the earlier row's engine.

D105 Pre-Purchase Checklist
- Deck and equipment: Identify the fitted deck, blades and discharge equipment. Measure gates and storage access against that configuration.
- Intended work: Compare the intended mowing route and attachments with the applicable operator manual’s operating restrictions.
- Operator fit: Inspect the seat, steering and controls; check reach, visibility and adjustment on the actual D105.
- Service and faults: Request operating hours and dated maintenance or repair records. For a running-cost comparison, use recorded fuel use from matched engines, workloads and mowing conditions.
Manuals and Current Service Parts
Obtain the manual for the installed engine and the applicable tractor/deck documentation. Use them for oil, filters, service intervals, cleaning, tire pressure and storage instructions.
Assess the Complete Offer
Ask for a written offer identifying the D105, attachments included, known repairs, transport costs and any warranty. Compare the complete offer and condition with alternative machines.

Just got my John Deere D105 last week and WOW! This thing cuts like butter! 😍 I’ve been mowing my lawn like a champ. The design feels sturdy and I love how comfy it is on long mowing sessions. Anyone have tips on the best mowing patterns? I’m still figuring out the best way to get my lawn looking like a golf course!
Great to hear you’re enjoying your D105! For mowing patterns, try to mow in a straight line and then alternate directions each time for an even cut.
That’s awesome, Liam! I usually do a double pass to get a clean cut. Makes a huge difference! 🌿
The build quality feels top notch. Seriously, you can tell it’s made to last. I’m curious about the maintenance part, though. Is it user-friendly? I don’t want to be the guy who needs to call a mechanic for simple fixes!
Good question, Jacob! Most owners find the D105 maintenance quite manageable, plus there are plenty of tutorial videos online.
Yes! Maintenance is actually pretty straightforward. The manual is pretty helpful for regular tasks!
I have mixed feelings… The D105 is definitely powerful, but I feel like the comfort could be improved. After an hour on this thing, my back starts feeling it. Did anyone else notice that? Is it just me? 😩
You might want to consider a back support pillow! I use one on my mower, and it helps a ton!
I didn’t have that issue, but I’m also a big fan of those cushy seat covers. They really help on longer jobs!
Charlotte, comfort can vary from person to person. Have you tried adjusting the seat? A little tweak can sometimes help!
So, I’ve been looking at the John Deere vs. some other brands, but honestly, I’m a bit overwhelmed. The comparisons made in this article helped a bit. But can anyone tell me if the D105 is really worth the few extra bucks compared to cheaper models? I just want a solid mower without breaking the bank. 🤔
I think it’s totally worth it! I’ve had mine for a year now and it’s been super reliable. The engine power makes all the difference! 💪
Agreed, Ryan! My friend had a cheaper model and it broke down within months. It’s not just about the cost upfront!
Hi Emma, it ultimately depends on your needs! If you have a larger yard or tough grass, the D105’s power is a great investment.
Okay, let’s be real — how does the D105 stack up against something like a Cub Cadet? Anyone feel like diving deep into that comparison? I need real opinions here, not just sales pitches! 😂
Great point, Ryan! John Deere’s support network is really extensive, which can make maintenance easier.
Honestly, I think John Deere has better resale value and parts availability. Cub Cadet is decent, but I’d lean towards Deere for quality.
I just read this article, and while I love the D105, it’s definitely not perfect. That cutting deck could be wider, right? Sometimes I feel like I’m mowing the same patch twice to get it all. Why can’t they just make it 5% bigger? 😂 A little improvement could go a long way! Anyone else feel that way?
Haha I get that feeling! It’s not a deal-breaker for me, but I have noticed I have to go over some spots twice! Maybe they’ll improve it in the next model.
Lol, you’re not alone, Oliver! If only everything came in ‘XL’, right?! 😂
