Our verdict
Murray's biggest petrol push. The InStart electric-start system is genuinely brilliant when it works — press button, mower starts — but the lithium battery pack is a known weak point, and out-of-warranty replacement is expensive enough to write the mower off. Buy new with full warranty or buy used very cheap; there's no middle ground that makes financial sense.
Pros & cons
Pros
- InStart push-button electric start — no pull cord
- Briggs 675iS is the upgraded 'is' (idle stop) variant
- 51cm cut covers ground fast
- Variable-speed self-drive
Cons
- InStart battery is consumable (~£40 every 4 years)
- 33kg is heavy on slopes
- Murray dealer support thin — InStart faults need B&S service centre

Buying second-hand
Used EQ700Xs are scarce because owners run them until the InStart dies, then bin them. £250-330 for a working example is realistic. The fallback pull-cord is fitted but hidden under the cowling — confirm it works before buying. If the InStart battery is dead, the seller usually doesn't know it's a £40 part and will accept £180 — that's the deal.
