Description
Overview:
This genuine Denso glow plug timer relay controls the pre‐heat cycle of diesel engine glow plugs on Kubota machinery, helping the engine start cleanly and reliably in cold or damp conditions. Built with a robust plastic body and metal terminals for dependable electrical contact, it replaces OEM reference 061700-3770 and related supersessions. The unit manages the on‐time of the glow plugs so they reach the correct temperature without over‐heating, protecting both the plugs and the battery. Suitable across a wide range of Kubota compact and utility tractors and grounds machines, including the BX1830D and B1550D, it is a straightforward, like‐for‐like service part to restore correct pre‐heat control when starting performance has degraded.
Key Features:
- Genuine Denso part for OEM‐level performance and fit
- Direct replacement for OEM No. 061700-3770 and listed supersessions
- Controls glow plug pre‐heat duration for reliable cold starts
- Helps prevent premature glow plug wear by avoiding over‐heating
- Durable construction with sturdy housing and quality terminals
- Consistent switching and timing for smooth engine start‐up
- Simple installation in the original relay position on the machine
- Suitable for a broad spread of Kubota tractors and utility models
- Cost‐effective preventative maintenance to restore proper pre‐heat control
Typical Applications:
Used on Kubota tractors, mowers, and utility vehicles to manage glow plug heating before cranking, improving start‐up in low temperatures, reducing white smoke, and stabilising idle during warm‐up. Ideal when engines are hard to start, glow indicators behave erratically, or plugs fail prematurely.
