Products Description
Lawn Mower Tractor PTO Clutch Ogura - GT1-TR05
Unlike ordinary PTO clutches without stopping function, this unit integrates built‑in brake structure, designed to bring blades to rapid halt once power cuts off, a core safety feature for Exmark, Toro and Snapper mid‑commercial mower fleets. It adopts 1‑inch shaft bore paired with 7.75‑inch pulley for either 1/2" or 5/8‑inch V‑belts, delivering 110 ft‑lbs rated torque under peak engine speed 3600 RPM.
In daily field operation, repeated brake‑engage cycles will gradually wear armature friction surfaces, shift air‑gap value and trigger delayed disengage or partial dragging issues. Our aftermarket unit optimizes friction formula and internal structural rigidity against such typical degradation. Every mounting footprint, brake spring setup and electrical connector strictly follows original reference specs, technicians can complete field swap without cutting or reworking machine brackets.
Each batch undergoes combined clutch‑brake functional validation: checking both engaging pulling force and braking response performance. It caters to mixed procurement needs for independent repair workshops, equipment rental yards and regional parts distributors across Americas.

Products Advantages
Why Choose Our Electric PTO Clutch over Generic Replacements?
Our Solution:
Tailored Cyclic Durability For Clutch‑Brake Working Mode
This Ogura‑pattern assembly bears dual workload: frequent electromagnetic engagement plus mechanical braking load. We select fatigue‑resistant brake spring sets and stabilized friction composite specially for repeated stop‑and‑go scenarios of mid‑size commercial mowers. It effectively reduces risks of spring distortion, friction‑face galling and air‑gap drift, common failure modes on budget copies running on Exmark / Toro / Snapper fleets.
Multi‑Model Cross‑Platform Compatibility Simplify Parts Stock
One single SKU covers multiple Exmark, Toro and Snapper mid‑commercial mower platforms that originally adopt Ogura GT1‑TR series clutch‑brake. Key parameters including 1‑inch bore, 7.75‑inch pulley dimension and CCW rotation fully match OEM drawings. No custom shims or on‑site machining needed during replacement. For parts dealers, this broad compatibility lowers total SKU count and eases warehouse inventory arrangement.
Stable Torque & Reliable Braking Response Under 3600RPM
Mid‑size commercial mowers often run near maximum 3600 engine RPM during lawn maintenance. Poor‑quality replacements tend to slip under rated torque or show sluggish blade‑stopping performance. Our upgraded internal components maintain consistent 110 ft‑lbs torque transmission; meanwhile the integrated brake module delivers fast blade halt after power loss, preserving original‑grade operational safety for turf crews.
Adapt To Seasonal Procurement Rhythm For Rental & Repair Business
Mower rental shops and local repair centers face obvious order swings tied to mowing seasons. We maintain cyclic production planning and reserved stock for this clutch‑brake SKU. Every finished product passes combined clutch‑brake function testing before shipment. Our supply chain supports large seasonal bulk purchase as well as small urgent restock orders; OEM branding options open for volume buyers.

FAQ
Q: How do I confirm this clutch‑brake assembly fits my mower?
A:This aftermarket unit is cross‑compatible with Ogura GT1‑TR05 related part numbers, also covers matching Exmark, Toro and Snapper OEM references. Core specs: 1‑inch bore, CCW rotation, 7.75‑inch pulley for 1/2" or 5/8" belts. Kindly cross‑verify your original component part number alongside machine model before purchase. Forward your equipment information, our technical staff will double‑check fitment for you.
Q: What is special for this brake‑integrated PTO unit compared to ordinary PTO clutches?
A: Different from simple power‑transfer clutches, this assembly incorporates mechanical brake springs and dedicated friction surfaces. Besides normal blade engagement, it delivers rapid blade‑stopping once power supply cuts off. We upgrade brake spring fatigue resistance and friction material to counter wear caused by repeated engage‑brake cycles, and sustain working temperature up to 365°F(185°C) under max 3600 RPM engine speed.
Q:Can I apply custom logo and personalized packaging for bulk‑volume procurement?
A:OEM custom service becomes accessible once meeting minimum‑purchase threshold. We can print or engrave brand logo on clutch housing, redesign outer carton and wiring bundle wrapping. Custom product development can also be discussed if you provide physical samples or engineering drawings.
Q: Any key maintenance points for this clutch‑brake unit?
A: Keep clutch‑brake zone clear of grass clippings and dirt buildup. Regularly inspect wiring harness and connector for abrasion or loose contact. Check abnormal dragging rotation after PTO disengage. Timely routine inspection helps preserve both torque‑transfer performance and blade‑braking function, extending overall service life.
