Bobcat T870 Track Options Explained
The Bobcat T870 is available in two undercarriage configurations that use different track sizes. This is the most common fitment mistake on this machine. The torsion mount T870 uses 450x86x60 (60 links). The suspension mount T870 uses 450x86x58 (58 links). These are NOT interchangeable — a 60-link track will not fit the suspension frame and vice versa.
What size rubber track does the Bobcat T870 use?
The Bobcat T870 uses a 450x86x60 (torsion) / 450x86x58 (suspension) rubber track with a Block (B) guide. It also accepts the 450x86x58 as a wider option. This machine produces 100 hp at an operating weight of 11,453–11,570 lbs with vertical lift geometry.
Other machines sharing this track size include: Bobcat T86 (replacement model) (Bobcat T86).
Can the Bobcat T870 run wide and narrow tracks?
No, but you must identify torsion vs suspension. Check your serial number or count the links on your existing track — 60 links = torsion, 58 links = suspension.
What is the best tread pattern for the Bobcat T870?
C-Block for general construction. Zig-Zag for mixed terrain. The T870's 100-hp engine handles all tread patterns well. X-Terrain available on both the 60-link and 58-link sizes.
Compare all patterns in our tread pattern guide.
How long do Bobcat T870 rubber tracks last?
1,200 to 1,800 hours. The T870 is being replaced by the Bobcat T86-2 Pro with 115 hp — same track sizes apply.
Maximize track life with proper tension (1–1.5" sag), daily undercarriage cleaning, and matching your tread pattern to your primary work surface. See our maintenance guide for the full checklist.
What undercarriage parts should I replace with new tracks?
Inspect sprockets, front idlers, rear idlers, and bottom rollers at every track swap. Replace sprockets every other track change (~3,000–4,000 hours). Worn undercarriage components destroy new tracks prematurely.
How much do Bobcat T870 replacement tracks cost?
Aftermarket OEM-spec tracks from TrackTECH cost significantly less than dealer OEM pricing while matching factory quality specs — continuous steel cord, anti-abrasion virgin rubber, and drop-forged steel guides. All tracks include free shipping and a 24-month warranty. See our OEM vs aftermarket comparison for details.
