Introduction
The Timberwolf TW-PRO is a formidable firewood processor, known for its robust construction and reliable splitting power. However, even the best machine can be elevated with the right add-ons. This article explores the key accessories and upgrades that transform the TW-PRO into a productivity powerhouse, helping operators cut cycle times and reduce fatigue. From log lift enhancements to conveyor systems, we break down the must-have gear for anyone serious about maximizing their output.
What Log Lift Accessories Are Available for the Timberwolf TW-PRO?
The standard manual log lift on the TW-PRO works well for smaller rounds, but for larger diameter logs or high-volume production, an upgraded hydraulic log lift is a game-changer. The Timberwolf factory offers a hydraulic log lift retrofit kit (part number TW-PRO-HLL) that attaches directly to the machine’s frame. This kit provides a lifting capacity of up to 1,200 pounds (544 kg) and uses the existing hydraulic system to raise logs up to 42 inches (107 cm) in length. The retrofit includes a heavy-duty pivot arm, a 3-inch bore cylinder, and a control lever mounted at the operator station. Installation takes roughly 4-6 hours with basic tools, and the cost in US dollars is around $1,295 to $1,495 depending on the dealer. For operators processing mixed hardwood species like oak or hickory, this accessory significantly reduces back strain and allows for a continuous flow of material.
Additionally, third-party manufacturers like LogRite offer aftermarket log lift attachments that can be adapted to the TW-PRO. These units often feature adjustable cradles and sometimes a telescoping arm for better clearance. However, they require careful measurement of the TW-PRO’s receiving tube diameter and mounting bracket spacing. It is recommended to compare the factory kit warranty (2 years) against third-party options, which typically offer 1 year of coverage. For most operators, the factory kit provides the best fit and reliability.
Which Conveyor Systems Increase Output the Most?
One of the most transformative upgrades for the TW-PRO is the addition of a conveyor system to handle split wood. Two primary types exist: a belt conveyor (often included in bundled packages) and a chain-and-slat conveyor. Belt conveyors from Timberwolf, such as the TW-PRO-BC, run at 60 feet per minute and can handle 30-inch-long splits. They are powered by a 1.5 HP electric motor (110V or 220V) and connect to the TW-PRO’s discharge chute. The belt model excels with clean, straight splits, moving them efficiently into a trailer or pile. The CAD price for this unit is approximately 2,895 CAD, including a 12-foot length.
| Specification | TW-PRO-BC (Belt) | TW-PRO-CS (Chain) |
|---|---|---|
| Type | Rubber Belt with Cleats | Steel Chain with Paddles |
| Max Split Length | 30 inches (76 cm) | 34 inches (86 cm) |
| Motor Power | 1.5 HP / 110V | 2 HP / 220V |
| Conveyor Speed | 60 ft/min | 45 ft/min |
| Weight Capacity | 400 lbs per hour | 600 lbs per hour |
| USD Price (approx.) | $2,195 | $2,895 |
| Best For | Clean splits, light use | Heavy, knotted, or wet wood |
The chain-and-slat conveyor (TW-PRO-CS) is the heavy-duty option, priced around 3,695 CAD in Canada. Its steel construction handles rough, knotted, or wet wood better than a belt, which can slip under heavy loads. For operators processing larger volumes (10+ cords per day), the chain conveyor is a worthwhile investment. Both units require a dedicated electrical circuit and can be mounted with a manual tilt bracket to adjust dump height. It is also wise to consider a cross-comparison with similar models to see how conveyors affect overall workflow.
What Hydraulic Upgrades Are Worth Adding?
The Timberwolf TW-PRO already features a strong hydraulic system, but several upgrades can boost its performance. The first is a high-flow pump kit. The standard pump delivers 11 GPM at 2,500 PSI, but a factory upgrade kit (TW-PRO-HF) increases flow to 14 GPM. This results in faster cycle times, particularly for the saw and splitter functions. The upgrade costs $1,095 USD and includes a new pump, valve block, and pressure relief valve. It also requires upgrading the hydraulic oil capacity to 12 gallons (45 liters) to prevent overheating. For operators splitting green ash or cottonwood (which are easier to push), the speed gain is noticeable—about 1.5 seconds per cycle.
Another beneficial upgrade is the addition of a hydraulic oil cooler. The standard TW-PRO has a small radiator, but for extended operation (over 4 hours continuous), an auxiliary cooler (TW-PRO-OC) is recommended. Priced at $895 USD, it includes a 12V fan and mounting brackets. This accessory reduces oil temperature by 15-20°F, extending seal and hose life. Installation requires tapping into the return line, and the kit comes with detailed instructions. For those who already own the machine, checking the hydraulic system specs can help determine compatibility.
Which Saw Blade and Bar Upgrades Improve Cutting Speed?
The stock saw bar on the TW-PRO is a 24-inch Oregon bar with a .325-inch pitch chain. While adequate, upgrading to a 28-inch bar (Oregon Pro-Tech or Timberwolf TW-PRO-28B) increases cutting capacity for larger logs. The longer bar allows you to slice through 28-inch diameter rounds without repositioning, saving time. The upgrade kit costs $299 USD and includes a bar, chain, and sprocket. The standard chain is a 72-drive link; consider switching to a skip-tooth chain for reduced drag on the saw motor. This is particularly helpful when cutting through frozen or dry hardwood.
Another accessory is the sharpening jig mount. Timberwolf offers a clamping jig (TW-PRO-SJ) that attaches to the saw head guard, allowing the operator to sharpen the chain in minutes without removing the bar. Priced at $149 USD, it holds the file at the correct angle (25 degrees) and depth gauge height. For operators who process hundreds of logs weekly, this keeps cutting performance consistent. Some dealers also offer carbide-tipped chain options (e.g., Oregon LPX) for longer edge retention, though these cost about $80 USD per chain versus $30 for standard steel.
What Splitter Accessories Enhance Versatility?
The splitter wedge on the TW-PRO is a 4-way design, but there are several add-ons to consider. A 6-way wedge (TW-PRO-6W) is available, costing $495 USD. This wedge splits logs into six pieces per stroke, ideal for thin kindling or stove-ready pieces. It is easily interchangeable with the standard wedge using a single pin. However, it requires higher hydraulic pressure; the standard system can handle it, but only if the logs are under 18 inches in diameter and relatively straight-grained. For twisted or knotted wood, the 6-way wedge may stall the splitter, so it is best used as a secondary tool.
Another useful upgrade is a log cradle extension. The TW-PRO has a 12-inch cradle depth, but an extension kit (TW-PRO-LCE) adds 6 inches for a total of 18 inches. This prevents logs from tipping during the split cycle, especially when working with shorter rounds (12-16 inches). The kit costs $195 USD and includes a steel plate and bolting hardware. Additionally, a log stop gate (TW-PRO-LSG) can be mounted at the end of the conveyor to prevent wood from falling off prematurely, priced at $125 USD. For operators looking to maximize split quality, these small add-ons reduce wasted motion and increase safety.
What Do Owners Say About TW-PRO Accessories?
Long-term owners consistently praise the hydraulic log lift upgrade. Marcus from Vermont reports, “I added the factory lift kit to my TW-PRO last year, and it cut my log handling time by 40%. It’s a no-brainer for anyone processing over 5 cords annually.” On forums like Firewood Hoarders Club, the conveyor systems receive high marks for reducing back strain, though some note that the belt model can slip in wet conditions. The 6-way wedge is a favorite among those selling kindling, with one user stating, “I produce 2 cords of kindling per week, and the 6-way wedge saves me an hour per day.”
Regarding the hydraulic cooler, several owners mention it extends operation times during summer months. Jake from Texas says, “In 95°F heat, the auxiliary cooler keeps the oil under 160°F, which is critical for long runs.” The saw bar upgrade is also well-received, with a logger in Maine noting, “The 28-inch bar lets me handle large red oak rounds that used to require two cuts.” However, a minority of owners advise against the high-flow pump kit unless you have a heavy-duty tractor or engine to drive it, as it can strain the PTO system. Overall, the consensus is that well-chosen accessories significantly boost the TW-PRO’s utility.
