Overview & Specs

GT 300 Grain Dryer Review, Specs & Buyer’s Guide — Canada

The GT 300 is a 350-bushel recirculating batch grain dryer from GT Manufacturing — a step up from the entry 245XL, pairing a larger batch with a 33-inch centrifugal fan for faster, quieter drying. With a 235 bu/h drying rate (at 5 points of moisture removal), a 2.2-million-BTU burner, and a PTO-driven design, it’s a practical small-to-mid farm dryer for operations that have outgrown the smallest batch machines but want to stay simple and affordable. GT Manufacturing has built recirculating batch dryers since 1953.

This guide covers the full official spec sheet, the recirculating batch process, Canadian pricing context, ownership notes, and how the 300 compares to its GT siblings.

Aglist quick take: The GT 300 is the value sweet spot at the small end of the GT range — 350-bu batch and a centrifugal fan that drives faster drying than the entry 245XL, at the same machine weight. Strong for small-to-mid prairie farms wanting simple PTO batch drying. Where it’s limited: still a batch machine (one batch at a time), so larger daily volumes point up the GT range to the RB and RAB models or to a continuous-flow dryer.

Quick Verdict — Who the GT 300 Is For

Buy it if: you want more capacity than the 245XL without a heavier or more expensive machine, value the faster-drying centrifugal fan, and run a small-to-mid farm where simple PTO batch drying fits. The 350-bushel batch and 235 bu/h rate suit moderate daily volumes.

Skip it if: your daily volume would make batch cycling a bottleneck (move up to the RB500/RB600/RB800 or RAB models), or you need continuous-flow throughput — see NECO mixed-flow or a GSI tower.

2. How the Recirculating Batch Process Works

In a recirculating batch dryer, grain is loaded as a batch into the bin, where a circulating auger continuously moves it up and around while a fan forces heated air through. The constant recirculation means every kernel passes the heat repeatedly, drying evenly. When the batch reaches target moisture it unloads, and the next loads. The 300’s 33-inch centrifugal fan is the upgrade over the 245XL’s axial fan — centrifugal fans handle static pressure well and run quieter, which on a 350-bushel batch translates to efficient, even drying. The trade-off versus continuous-flow remains total daily throughput, since you dry one batch at a time.

4. How the GT 300 Compares

Spec	GT 300	GT 245XL	GT 345XL
Drying capacity	235 bu/h	140 bu/h	235 bu/h
Batch capacity	350 bu	200 bu	350 bu
Fan	33″ centrifugal	26″ axial	26″ axial
Recirc time	5–7 min	5–7 min	10–12 min
Weight (PTO)	2,900 lb	2,900 lb	3,350 lb

Where the 300 wins: larger batch than the 245XL at the same weight, and its centrifugal fan with the short 5–7 minute recirc time gives it an efficiency edge over the 345XL (which shares the batch size but uses an axial fan and a longer 10–12 minute cycle). A strong value pick. For the full lineup, see the GT grain dryers hub.

5. Real-World Performance

The 300’s 235 bu/h at 5 points, paired with the 350-bushel batch and quick recirculating cycle, makes it a capable small-to-mid farm dryer. The 33-inch centrifugal fan is the standout — quieter and stronger against static pressure than an axial fan, contributing to even, efficient drying. PTO drive keeps it usable in yards without three-phase power. For farms drying for storage and local sale at moderate daily volumes, it’s a well-balanced machine.

6. Common Problems & Reliability Notes

Transparency note: general batch-dryer ownership considerations, not model-specific defects. Batch dryers are mechanically simple, which favours reliability. Keep the circulating auger and drive in good order, maintain burner and vaporizer, check fan clutch and belt and the PTO driveline, and observe propane discipline in cold prairie conditions. No notable catastrophic-failure pattern is associated with the GT batch line.

7. Price Range in Canada

New pricing varies by dealer, configuration, and province — contact a Canadian GT dealer for a quote. Used GT batch dryers appear regularly on AgDealer, Ritchie Bros, and BigIron. GT notes its dryers hold high resale value and often pay for themselves in 1–3 years.

8. Best Use Cases in Canadian Conditions

Small-to-mid prairie farms (SK / AB / MB) drying for storage and local sale at moderate volumes. Remote yards without three-phase power (PTO drive). Operations wanting faster drying than the entry model via the centrifugal fan. Not ideal for: large daily volumes (move up the GT range) or continuous-flow needs.

9. Maintenance & Service

Maintain circulating auger and drive — central to even drying
Service burner and vaporizer; propane discipline in cold weather
Check fan clutch, belt, PTO driveline each season
Inspect grain sampler and controls
Keep a ULC-approved fire extinguisher with the dryer

10. GT 300 FAQ

How much grain can a GT 300 dry? 235 bu/h at 5 points of moisture removal, with a 350-bushel batch capacity. Throughput varies with crop, starting moisture, and conditions.

What’s the difference between the GT 300 and 345XL? Both have the same 350-bushel batch and 2.2M BTU burner, but the 300 uses a 33″ centrifugal fan with a 5–7 minute recirc time, while the 345XL uses a 26″ axial fan with a 10–12 minute cycle and a taller plenum. The 300 is the faster-cycling, lighter machine.

Is the GT 300 PTO or electric? PTO-driven standard (475 rpm), with an optional 20 HP electric motor.

Is the 300 still made? Yes — it’s part of GT Manufacturing’s current recirculating batch lineup.
