MOUNTFIELD HP42 Petrol Lawnmower Reviews

18 reviews for MOUNTFIELD HP42 Petrol Lawnmower

  1. Nick Walmsley

    Absolute garbage. Used it twice last year. Now it won’t start. Drained fuel – added new fuel. Nothing. Will be claiming on the warranty. Simply not fit for purpose. My old Stiga never missed a beat and was fine with any old fuel left in it over winter. Pathetic.

  2. Ian Gough

    Easy to assemble, started first pull of the cord, seems to be a superb mower for the price range

  3. Julie Grech

    5* very pleased with purchase. Have previously owned a Mountfield for quite a number of years so know they are reliable.

    Excellent mower, very easy to use. Have previously owned a Mountfield for quite a number if years so know they are reliable.

  5. Michael

    Can’t rate performance because it’s too late to cut my lawn but I bought this model on my next door neighbour’s advice he has this model and can’t fault it. It took less than 15 minutes to assemble the machine and it looks very impressive so I’m now waiting for the right conditions to fire it up and start cutting

  6. Paul

    Instructions a little hard to follow, however, the machine is exactly what we needed for the garden.
    Very light to use and starts first time.
    Excellent service from the supplier!!

  7. Brian White

    Very well packaged, very easy to start does a very good job

  8. Caroline Rogers

    Very good lawnmower would highly recommend

  9. Sharon Young

    We are very pleased with our purchase. The lawn mower was delivered promptly on the specified day. Easy assembly with clear instruction. Took only a few minutes before we were using our new machine, with the oil that came with it. One very happy customer.

  10. Mr Stephen Barratt

    Starts first time, easy assembly, easy and comfortable to handle and quiet. Excellent value for money.

  11. Joanna

    This is excellent, only used it once but very happy with it
    Putting it together was a little challenge as instructions not easy to follow

  12. Norman Smith

    Easy to start, quiet, large collection bag & very easy to use

  13. customer Tom Sharp.

    Very easy to handle cuts beautifully.

  14. rob

    Prompt delivery, easy to assemble and use

  15. Ed Cranford

    All assembled but owing to other workload in my home, so far I’ve not used it at all. I’m sure it will be fine but to stop Trustpilot badgering me for a review, here it is.

  16. Mrs. Elizabeth Wilkinson

    It was assembled without difficulty, started first time and made an excellent job of cutting the grass. Although this model does not have power steering, it was quite easy to push on our flat lawn. This might be because it does not have a roller on the back, as striped grass was not needed. However it does have a mulching option, which will be useful, as emptying grass collector and disposal of cuttings adds time. I thought the inclusion of the oil was a nice touch, as it meant we could get on with the job right away. Very satisfied!

  17. Craig Sharp

    Very good mower much lighter and easy to handle than my old Ryobi. Ordering & delivery very straight forward although wasn’t able to track through TNT so missed initial delivery slot. Assembly instructions could have been clearer and so took longer than expected but so far happy with purchase.
