GT Grain Dryers Specs, Reviews & Ratings in Canada

GT Manufacturing has built recirculating batch grain dryers since 1953 and calls itself a worldwide leader in the batch field. For Canadian farmers, GT fills a specific and valuable niche: the simple, affordable, often PTO-driven batch dryer that suits small and mid-size operations. Where other brands build continuous-flow towers and mixed-flow machines for high daily volumes, a GT batch dryer dries grain one batch at a time — mechanically straightforward, usable in any yard without three-phase power, and a low-cost entry into on-farm drying. GT notes its dryers often pay for themselves in one to three years and hold strong resale value.

Aglist is built to make GT easy to compare. Here you can browse the full GT lineup by model and capacity, open a model page for a structured spec breakdown sourced from GT's official specifications, and understand how batch drying differs from the continuous-flow machines used by larger operations. Whether you're sizing a small-farm dryer, comparing GT's axial-fan XL series against its centrifugal-fan RB series, or weighing a used GT or Tox-O-Wik on the prairie market, this brand hub is the starting point.

Browse GT Grain Dryers

GT dryers are named by their bushel capacity and split into three groups: the axial-fan XL series, the centrifugal-fan RB series, and the all-automatic RAB series. Use the links below to explore the models on Aglist, then drill into detailed pages with specs, the batch process, pricing context, and reviews.

GT XL Series (Axial Fan)

The XL series uses axial fans — lighter and lower-cost — across the small-to-large batch range.

GT 245XL — entry 200-bushel batch, the most affordable GT
GT 345XL — 350-bushel batch, taller plenum
GT 545XL — 500-bushel mid-range batch
GT 645XL — 640-bushel batch, largest XL

GT RB Series (Centrifugal Fan)

The RB series uses 38-inch centrifugal fans — quieter and stronger against static pressure.

GT 300 — 350-bushel batch, fast-cycling centrifugal fan
GT RB500 — 500-bushel centrifugal-fan batch
GT RB600 — 640-bushel centrifugal-fan batch
GT RB800 — 820-bushel batch, GT's largest manual model

GT RAB Series (Automatic)

GT RAB5000 — all-automatic batch with GT Grain Guard control

GT also offers the larger automatic RAB8000 and a newly introduced 21T-820 bushel model at the top of the range. For the full model-by-model breakdown, the batch-vs-continuous comparison, and the used Tox-O-Wik market, see the complete GT Grain Dryers guide.

What Specs Matter Most When Comparing GT Grain Dryers

A GT batch dryer is best chosen on three decisions, plus an understanding of the batch process itself.

Batch Capacity

Match the batch size to your realistic daily intake. Because a batch dryer processes one batch at a time, capacity is set by batch size and recirculating time. The 200–350 bushel models (245XL, 300, 345XL) suit small farms; the 500–640 bushel models (545XL, RB500, 645XL, RB600) suit mid-size operations; the 820-bushel RB800 and automatic RAB models suit larger farms.

Fan Type — Axial vs Centrifugal

Several capacities are offered both ways. Axial fans (XL series) are lighter and lower-cost; centrifugal fans (RB series) run quieter and handle static pressure better. The 545XL versus RB500 and the 645XL versus RB600 decisions come down largely to this choice.

Power — PTO vs Automatic Electric

The XL and RB models run off a tractor PTO, with an optional electric motor, so they work in any yard without three-phase power. The automatic RAB models use three-phase electric power and the GT Grain Guard control system for hands-off cycling — suited to larger operations that want to save labour during harvest.

Burner and Recirculating Time

Burner output ranges from 2.2 million BTU on the smallest models to 3.5 million BTU on the automatic RAB5000. Recirculating time — how long a batch cycles to reach target moisture — rises with batch size, and affects how many batches you can run in a day.

GT Reviews on Aglist

Specs help you compare, but reviews help you decide — and owner data on batch dryers is genuinely scarce online. Owner reviews highlight what matters after the purchase: burner and auger reliability, real drying capacity on your crops, fuel use, ease of operation, and serviceability. On Aglist, reviews are submitted by users and moderated to reduce spam and abuse. They reflect personal experience, so treat them as guidance rather than a guarantee.

If you own or have run a GT dryer — current model or an older Tox-O-Wik — your review is especially valuable. Even a short note helps: mention your model, what crops you dry, and how it performs through a prairie harvest.

Popular Comparisons Canadian Buyers Make

Many GT searches start with one model and end with a comparison. Aglist is built for that path.

Common GT comparison angles:

545XL vs RB500 — axial versus centrifugal fan in the 500-bushel class
645XL vs RB600 — axial versus centrifugal in the 640-bushel class
RB800 vs RAB5000 — largest manual batch versus all-automatic
GT batch vs continuous-flow (NECO, GSI, Vertec) — simplicity and value versus throughput

For the full range, the batch-vs-continuous breakdown, and the used Tox-O-Wik market, see the GT Grain Dryers guide. For other dryer types, browse the grain dryer category and the Best Grain Dryers in Canada guide.

Important Note About Specifications

Aglist aims to keep specs accurate, but details can vary by model year and configuration. Specifications come from GT Manufacturing's official model pages and are subject to change without notice; drying capacities are quoted at 5 points of moisture removal and vary with crop, starting moisture, and conditions. Before buying, servicing, or repairing equipment, double-check key specs with GT documentation, the owner's manual, or your Canadian dealer.

GT Grain Dryer FAQ

Are GT grain dryers still made?

Yes. GT Manufacturing has built recirculating batch dryers since 1953 and offers a full current lineup from the 200-bushel 245XL through the manual RB series to the automatic RAB models. GT also supports its legacy machines, including older Tox-O-Wik dryers, with manuals, technical tips, and parts.

What is a recirculating batch grain dryer?

It loads grain as a single batch, then a circulating auger continuously moves the grain while a fan forces heated air through it, drying every kernel evenly. When the batch reaches target moisture it unloads and the next loads. It's mechanically simple, often PTO-driven, and suited to small-to-mid farm volumes.

What's the difference between GT's XL and RB series?

Both are batch dryers, but the XL series uses axial fans (lighter, lower-cost) while the RB series uses 38-inch centrifugal fans (quieter, stronger against static pressure). Several capacities come both ways — the 545XL and RB500 share a 500-bushel batch, differing mainly in fan type.

Do GT dryers need three-phase power?

The XL and RB series run off a tractor PTO, with an optional electric motor, so they work in any yard. The automatic RAB series uses three-phase electric power for hands-off operation. Confirm your power supply when choosing between them.

What is a GT Tox-O-Wik dryer?

Tox-O-Wik is GT's legacy line of portable PTO-driven batch dryers, common on the prairie used market. They're a low-cost entry into on-farm batch drying — buy on condition, checking the burner, auger, fan, and PTO driveline.
