Sizing a Komatsu Forest Forwarder: 825TX, 845, 875, and 895 Compared

Four Forwarders, Four Different Jobs

Komatsu Forest doesn't build one forwarder and call it a lineup -- it builds four genuinely different machines, from a thinning-specific unit engineered around protecting standing trees to a 44,000-lb flagship built to move maximum volume off a clearcut. We've already given each of these machines its own spotlight. This piece puts all four side by side, because sizing the right one is really a decision about your tract mix, trail conditions, and harvester output -- not about which machine has the biggest number on the spec sheet.

The Numbers, Side by Side

The 825TX sits at the bottom of the lineup by design, not by limitation: a 9,000 kg (19,842 lb) rated load on roughly 14,580 kg (32,143 lbs) of operating weight, powered by a 127 kW diesel. It's built around a tracking rear bogie that keeps the rear wheels following the fronts within less than 200 mm of deviation -- a thinning-specific feature that has nothing to do with payload and everything to do with not scraping bark off the trees you're not cutting.

The 845 nearly triples that into genuine mid-size territory: a 12,000 kg (26,455 lb) rated load on about 16,950 kg (37,368 lbs) of operating weight, a 140 kW diesel, and 172 kN of tractive force. That tractive force number -- the machine's actual ability to pull a loaded chassis through soft ground or up a grade -- is arguably more important day to day than the payload figure, especially on the tighter, less-improved trails that come with thinning work.

The 875 is the bridge machine, and its spec sheet makes the bridging explicit: a 16,000 kg (35,274 lb) rated load -- roughly 9,000 lbs more than the 845 -- on 17,800 to 20,100 kg (39,242 to 44,335 lbs) of operating weight depending on configuration, with a 190 kW diesel. Its 214 kN of tractive force matches the flagship 895 exactly, even though it carries noticeably less payload -- a deliberate choice that keeps the 875 mobile on the same difficult ground the bigger machine handles, at a price point still meaningfully below it.

At the top, the 895 is built for contractors who need maximum volume per trip and nothing else: a 20,000 kg (44,092 lb) rated load, a 214 kW diesel producing 1,280 Nm of torque, and the same 214 kN tractive force as the 875 but with double the hauling capacity to actually use it on. Komatsu doesn't badge any of these forwarders with the dash-number generation convention you'd see on its excavators and dozers, so there's no documented predecessor comparison to give you for any single model in this lineup -- we'd rather say that plainly than invent one. What's verifiable is each machine's current position relative to its siblings, and that's the comparison that actually matters when you're deciding which one to buy.

Matching the Machine to Your Tract Mix

If your work is dominated by pre-commercial and commercial thinning with landowner agreements that penalize damage to residual stands, the 825TX is the only machine in this lineup actually engineered around that specific problem -- the 845 and up will move more wood, but none of them share the 825TX's tracking-frame geometry. If you're running a mix of smaller parcels through a season rather than one big clearcut, the 845 is sized specifically so you're not financing flagship capacity you'd rarely use -- 26,455 lbs covers the large majority of thinning-volume loads without the extra fuel burn and purchase cost of a bigger machine.

The 875 earns its place for an operation that's outgrown the 845's payload but doesn't have the volume to justify a full flagship, especially on steeper or softer ground where that flagship-matching tractive force keeps the machine moving loaded. And the 895 makes sense specifically for large-tract operations and high daily production quotas, where every trip's fixed time cost (driving to the pickup, loading, driving back, unloading) gets diluted across the maximum possible payload -- the entire economic argument for flagship capacity breaks down fast if your actual loads never approach 44,000 lbs.

Pairing a Forwarder With Your Harvester

None of these four forwarders work in isolation on a cut-to-length operation -- they're paired with a harvester, and matching forwarder capacity to harvester output is as much a part of this sizing decision as the tract itself. Komatsu's own 951XC-2 eight-wheeled harvester is the natural pairing machine across this lineup, and a harvester that's outpacing your forwarder's hauling capacity is one of the clearest signals you've undersized the forwarder side of the operation.

For a deeper look at any single machine in this lineup, our individual spotlights cover the 825TX's thinning-specific design, the 845's mid-size positioning, the 875's bridge-class role, and the 895's flagship payload in more detail than a side-by-side comparison has room for.

The Honest Rent-vs-Own Case Across This Lineup

Forestry-specific rental fleets are smaller and get booked up faster than general construction rental yards, especially during peak harvest windows -- and the bigger the machine, the thinner that rental availability gets. If you've had to turn down a thinning contract because the right machine wasn't available to rent in time, or scrambled for forwarder availability more than once in a season you could see coming, that's the clearest signal ownership belongs in your plan rather than another rental.

There's also a bidding advantage worth weighing beyond pure utilization math: a contractor who owns the right forwarder for their typical tract size can credibly bid on jobs that a contractor dependent on rental availability has to think twice about. Our overview of financing Komatsu Forest equipment covers the rent-vs-own math in more depth across Komatsu's full forestry range, not just the forwarder side of it.

We won't quote a payment figure here -- forestry equipment financing is structured around your credit profile and time in business, with down payments typically ranging from $0 for excellent credit up to 20-30%, sometimes 40% for a newer operation. An actual application gets you real numbers to plan a season around, across any of these four machines.
