Overview & Specs

GT 345XL Grain Dryer Review, Specs & Buyer’s Guide — Canada

The GT 345XL is a 350-bushel recirculating batch grain dryer from GT Manufacturing, sharing the 300’s batch capacity but built on a taller plenum with a 26-inch axial fan and a longer recirculating cycle. With a 235 bu/h drying rate (at 5 points of moisture removal), a 2.2-million-BTU burner, and PTO drive, it’s a small-to-mid farm batch dryer in GT’s XL series. GT has manufactured recirculating batch dryers since 1953.

This guide covers the full official spec sheet, the batch process, Canadian pricing context, ownership notes, and GT lineup comparisons.

Aglist quick take: The 345XL is the taller-plenum, axial-fan member of GT’s 350-bushel class. It does the same core job as the 300 with a different fan and longer recirc cycle. Strong for small-to-mid farms wanting simple PTO batch drying. Where it’s limited: batch throughput caps daily volume; larger operations should look at the RB and RAB models.

Quick Verdict — Who the GT 345XL Is For

Buy it if: you want a 350-bushel batch dryer in GT’s XL series, run a small-to-mid farm, and value simple PTO drying. Skip it if: daily volume would bottleneck batch cycling (step up the GT range), or you need continuous-flow throughput (NECO or GSI tower).

2. How the Recirculating Batch Process Works

Grain loads as a batch; a circulating auger moves it continuously while a fan forces heated air through, drying every kernel evenly through repeated recirculation. At target moisture the batch unloads. The 345XL’s taller plenum (18 ft 4 in to the auger top) and 26-inch axial fan give it a 12,000 CFM airflow and a 10–12 minute recirculating cycle — a different drying profile from the centrifugal-fan 300. As with all batch dryers, daily throughput is set by batch size and cycle time.

4. How the GT 345XL Compares

Spec	GT 345XL	GT 300	GT 545XL
Drying capacity	235 bu/h	235 bu/h	335 bu/h
Batch capacity	350 bu	350 bu	500 bu
Fan	26″ axial	33″ centrifugal	32″ axial
Recirc time	10–12 min	5–7 min	12–15 min
Weight (PTO)	3,350 lb	2,900 lb	4,400 lb

Where the 345XL fits: the taller-plenum axial-fan option in the 350-bushel class. The 300 cycles faster with its centrifugal fan; the 545XL steps up to a 500-bushel batch. Choose by fan preference and how the plenum height suits your setup. See the GT grain dryers hub for the full range.

5. Real-World Performance

The 345XL delivers 235 bu/h at 5 points with a 350-bushel batch. Its 12,000 CFM axial fan and taller plenum give it a solid airflow profile, with the 10–12 minute recirc cycle reflecting the larger plenum volume. PTO drive at 525 rpm keeps it independent of three-phase power. A capable small-to-mid farm batch dryer for storage and local-sale drying.

6. Common Problems & Reliability Notes

Transparency note: general batch-dryer considerations, not model-specific defects. Maintain the circulating auger and drive, burner and vaporizer, fan clutch and belt, and the PTO driveline; observe propane discipline in cold weather. The simplicity of the batch design favours reliability.

7. Price Range in Canada

New pricing varies by dealer, configuration, and province — request a quote from a Canadian GT dealer. Used GT batch dryers appear on AgDealer, Ritchie Bros, and BigIron. GT cites high resale value and 1–3 year payback on working farms.

8. Best Use Cases in Canadian Conditions

Small-to-mid prairie farms (SK / AB / MB) at moderate daily volumes. Remote yards without three-phase power. Operations preferring an axial fan and taller plenum in the 350-bushel class. Not ideal for: large daily volumes or continuous-flow needs.

9. Maintenance & Service

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

10. GT 345XL FAQ

How much grain can a GT 345XL dry? 235 bu/h at 5 points of moisture removal, 350-bushel batch. Throughput varies with crop and conditions.

GT 345XL vs 300 — what’s different? Same batch (350 bu) and burner (2.2M BTU), but the 345XL uses a 26″ axial fan, a taller plenum (18 ft 4 in), and a 10–12 minute recirc cycle, while the 300 uses a 33″ centrifugal fan and a 5–7 minute cycle at lower weight.

Is the 345XL PTO or electric? PTO standard (525 rpm), optional 20 HP electric motor.

Is it still made? Yes — part of GT’s current XL batch series.
