Product Details


This MTD46 Thorx Engine Push Propelled Rotary Petrol Lawn Mower is hand propelled, easy to use, and highly durable. The lawn mower is constructed from a high quality steel mower-deck, making the lawn mower robust and impressively durable. This petrol-powered lawn mower has a reliable and powerful MTD Thorx engine. This features an oil-foam air-filter with an aluminium cylinder so as to maximise service-life, utilising the overhead-valve technology and significantly reducing exhaust-emissions, sound-output, and fuel-consumption.

The MTD46 Petrol Lawnmower has superior maneuverability, which is useful for those who have flowerbeds, trees, and shrubs to work around. The large 70 litre capacity fabric grass bag has a large opening for easy emptying, whilst the ergonomic handles are foldable for easy transportation and more compact storage between uses. 

The cutting deck is fitted with special hi-lift blades which give a clean cut and excellent collection. The cutting height can be individually adjusted using the six cutting positions ranging from 20mm to 90mm, enabling you to manage a variety of grass-types. The ergonomically shaped handlebar facilitates long periods of low-fatigue mowing.

      MTD Thorx 123cc 18" (46cm) Push Propelled Rotary Petrol Lawn Mower - Model MTD46 is rated 4.3 out of 5 by 42.
      Rated 5 out of 5 by from light and easy to use this is a light and easy to use lawnmower, our lawn has lots of fiddly bits and this mower is a lot easier to manoeuvre into those places than our old heavy mower. Because it is light the fact it is only push propelled is not a problem. The only problem we have had is when it arrived the handle wasn't fitted to the mower. We had to get some star washers, remove the old ones on the spindle, attach the handle and then fit new star washers. Apart from that it seems well built for the price paid.

      Rated 5 out of 5 by from Neat machine Bought this petrol lawn mower as a replacement for an old corded rotary one we had for years. It's the first petrol mower I have ever owned and must say for the price a great piece of kit. Would recommend this model as its a good size, great price and perfect for reasonably sized lawn. The downside was the instructions were not the best and not clear as to the basic starting of the machine. Be advised you need oil and unleaded petrol to begin with ! Well that's what I used and it worked

      Rated 4 out of 5 by from Good, if you can assemble it... Good price for a reliable machine that actually starts first time and cuts grass rather well. Finishing touches not great - all four plastic wheel covers fell off on first use and second use and have now been binned. Instructions for assembly hopeless, make an MFI wardrobe assembly child's play. User manuals (one for machine, one for engine) run to 200 pages each, of which 6 pages or so are in English. But so far it does a good job

      Rated 4 out of 5 by from Up and running in no time Looked long and hard at petrol rotary mowers and this has proved to be a worthwhile choice. Arrived promptly with no complications and was easily assembled. Having already purchased petrol and oil the mower really did start first time! This mower allows for individual wheel adjustment that I personally prefer. I have previously owned petrol mowers and this one is as good as any of those.

      Rated 5 out of 5 by from A great little petrol mower A real value for money petrol mower with a motor powerful enough to get through tall ryegrass. I saw a post about the oil being hard to acquire but the SAE30 oil specified is standard for petrol mowers so don't panic. Had a couple of hiccups assembling it but that is just because I played my man card and refused to look at the instructions, it is actually fairly easy.

      Rated 5 out of 5 by from Easy to assemble good cut Found the machine easy to assemble and setup. Has adequate height adjustment to suit English lawn. Overall very please with purchase. Only down side was delivery company DPD who were appalling and wasted a day of my time at home! Its areal shame Costco use DPD who have poor customer service when things go wrong and are not honest with customer as to situation.

      Rated 4 out of 5 by from So far so good Pros: -Great value for money. Excellent delivery (next day) Starts easily and is light and manoeuvrable. Cut level means adjusting all 4 wheels using a very basic device. Folds down for practical storage and transport. Cons:- Height adjustment slots are not easy to see.Although there is not much to assemble, the instructions are anything but clear

      Rated 3 out of 5 by from 50/50 good but has some concerns Had it a week now. Good points:- looks good. Cuts grass. Not hard to start. Good volume basket to collect grass. Manouveres easily. Price. Bad points:-instruction! Terribly confusing. Cannot get the blade to lower and the epic journal of instructions is of no help at all with some diagrams not related to product.
