This pump bolted right onto my TL100A with perfect fitment. No more hydraulic issues - pressure tests show it's performing like new. Genuine quality at an affordable price.
The motor arrived well-packaged and installed easily. Performance matches OEM specs exactly - no leaks and smooth operation. Saved me hundreds compared to dealer price
fastish shipping. item well packaged. item as described. very happy
Good quality, condition & value. Seller acted quickly to rectify a problem with delivery. I would definately buy from this seller again.
The box was beat up but the adapter was in good condition. It works good on the snow pusher we put it on but probably isn't heavy enough for major digging which is fine for our situation. It is light enough to lift by the handles and put it on the bucket. We put it on the loader first and picked up the bucket then pulled the latches so the bucket could fall in. So overall a good economy adapter.
