Spectrum SP8100TS 420cc Petrol Micro Crawler Excavator | 807mm Access Width

Spectrum SP8100TS 420cc Petrol Micro Crawler Excavator

The problem with hiring a digger for a garden job is rarely the digger. It is the gate. Most compact excavators are a metre or more across the tracks, which means taking down fence panels, lifting a gate off its hinges, or running the machine across a lawn you were trying to protect. At 807mm wide, the SP8100TS goes through a standard side access, down an alley between houses, and into a back garden without anything being dismantled first — and that is the single reason most people buy one.

Small enough to get in, strong enough to be worth it

Narrow machines are easy to make. Narrow machines that still dig properly are the harder problem. The SP8100TS runs a 420cc petrol engine producing 2.2 tonnes of bucket breakout force and 3.2 tonnes of arm force — enough to break into compacted clay, lift out old footings, and cut a clean trench rather than scraping at the surface. It will dig to 1,320mm deep with a 2,900mm working radius and load over the side of a trailer or skip at up to 1,150mm.

A word on that 2.2-tonne figure, because it is easy to misread: it describes digging force, not machine weight. The SP8100TS itself weighs 680kg. That is the point — you get the breakout force to do real groundwork from a machine light enough not to churn a lawn, light enough to move on a standard plant trailer, and small enough to store in a garage between jobs.

Tracks, slopes and working in a confined space

The tracked crawler undercarriage spreads the machine's weight and grips where wheels would spin — wet clay, loose spoil, soft ground and rutted site access. Rated to a 30° gradeability, it will work confidently on banks and sloping gardens where a wheeled machine starts to feel uncomfortable. Travel speed is a deliberate 2.16km/h: this is a machine for working, not commuting across a site.

The 360° slewing platform is what makes it usable in a tight garden. Dig, slew, dump into the barrow or trailer behind you, slew back — without repositioning the tracks each cycle. In a confined space that is the difference between steady progress and spending half the day shuffling the machine around.

What it is for

Drainage runs and soakaways. Footings for an extension, a garden room or a garage base. Pond and water-feature excavation. Lifting out tree stumps and old concrete. Trenching for cable, water or irrigation. Levelling and ground preparation before a patio or a new lawn. Landscaping work where a mini-digger hire would cost you a day of delivery, collection and gate removal before you turn a sod.

Supplied with a 200mm digging bucket, sized for trenching and accurate excavation.

Please read: domestic use only

This machine is supplied for domestic use only. The 5-year Spectrum warranty applies to private, non-commercial use — it does not cover use by commercial operatives or on trade groundworks. If you are buying for a landscaping or groundworks business, please speak to us before ordering so we can point you at the right machine. As with any excavator, check for buried services before you dig and use appropriate PPE.

Backed for five years

Spectrum machinery carries our 5-year warranty — several times the cover offered on most imported compact plant, and worth weighing against the cost of repeated hire. Three or four weekends of mini-digger hire, delivery and collection is a meaningful fraction of buying one outright, and at the end of it you own nothing.
